AI (augmented intelligence) promises to be a transformational force in health care, especially within primary care. Experts outline ways that innovations driven by AI - often called artificial intelligence - can aid rather than subvert the patient-physician relationship including Aysa's impact on diagnostics.
Technological and chemical advances continue to bring new dermatological products to market, promising healthy, moisturized skin. But a product discovered in the 19th century still tops dermatologists’ recommendations for healing and keeping skin healthy: petroleum jelly.
You may have an old jar of petroleum jelly collecting dust in the back of your medicine cabinet, but did you know just how versatile that petroleum jelly can be? We’ve rounded up 10 ways you can use petroleum jelly today.
- Heals minor skin scrapes and bruises – Petroleum jelly keeps the area moist, preventing the wound from drying out and forming an ugly scab. It can also keep the scrape or bruise from getting worse. Remember to clean the area first before applying the jelly.
- Relieves dry skin – Dry skin can appear dull and rough, with fine scales that flake off easily. It can be itchy and sometimes even crack and bleed. Rub petroleum jelly on dry patches including your eyelids and lips to relieve itch and stop the flaking. Apply to dry chapped noses during cold and allergy season.
- Moisturizes – Step out of the shower and apply the jelly (like you would with lotion) to lock in moisture to the skin. For lips, use just like Chapstick.
- Saves your hair – Swimming in pool water, the summer sun, and wind can all dry your hair out. Petroleum jelly can lessen the appearance of split ends and add luster. Just rub a small amount in your palms and apply to the ends of your hair.
- Treats diaper rash – If your baby has a diaper rash, apply the jelly during each diaper change. If applied properly, the rash should clear up within a few days. If the rash does not go away, seek help from your child’s pediatrician or a dermatologist.
- Prevents chafing – Chafing happens when body parts rub together or against clothing, causing a painful skin irritation. Apply petroleum jelly to problem areas like the inner thighs, underarms, or nipples to prevent the irritation.
- Prevents skin stains – Looking to dye your hair or get a spray tan? Apply the jelly around your hair line or on your cuticles so the dye or spray tan doesn’t stain your skin or accumulate in your nail beds.
- Rehydrates your nails – If you treat yourself to mani-pedis, apply petroleum jelly to your nails and cuticles in between polishes. This hydrates your nails, cutting down on potential breakage and chipping. It’s best if you apply it when your nails are damp.
- Saves your pet’s paws – After you’ve gone for a stroll with your pet, clean his or her paws with gauze, dry, then apply the jelly.
- Helps remove stuck objects – Stubborn ring won’t come off? Apply a little around the stuck object to safely remove.

Most people are probably familiar with or have heard of Botox, but how much do you know about what it’s used for and how it works? Botox is one of several brands of injectable medicine (such as Dysport, Xeomin, and Jeuveau) that contain the molecule botulinum toxin. Botulinum toxin is a protein that is produced by the bacteria Clostridium botulinum that has some very interesting properties. This protein has the ability to paralyze the respiratory muscles necessary to breathe. However, scientists have found ways to harvest and utilize this toxin in very small concentrations to safely treat a number of medical and cosmetic conditions such as muscle spasticity, excess sweating, wrinkles, migraines, and more. The two conditions that most commonly bring patients to dermatology offices for botulinum toxin injections are wrinkles and excessive sweating.
Dermatologists (and many other healthcare providers) offer botulinum toxin injections to prevent and reduce wrinkles. As we age, our skin becomes thinner and less elastic, creating creases in the skin that we can wrinkles. When the muscles of our face move, they scrunch up the overlying skin and decrease the appearance of wrinkles. In addition to minimizing the appearance of wrinkles that are already there, the paralysis of the muscles can also have a preventative effect by slowing down the process of wrinkles being etched into the skin in the first place. While botulinum toxin paralyzes these muscles, the paralysis doesn’t last forever. Eventually, the body breaks down the botulinum toxin and the muscles are able to move again. This typically takes around 3 to 4 months; however, the length of effect can be shorter or longer depending on the person.
The less frequent use of botulinum toxin in dermatology is for treatment of excess sweating (hyperhidrosis). Hyperhidrosis is a medical condition in which a patient has unusually high sweat production, beyond what is considered normal or appropriate for regulating body temperature. Hyperhidrosis can either be generalized, in which there is diffuse sweating all over the body, or it can be localized, in which is affects only specific locations in the body – most commonly the hands, feet, face, armpits, or groin. In the same way that botulinum toxin blocks the nerves that control the muscles, it can also block the nerves that control the sweat glands. This effect can drastically reduce the excessive sweating from hyperhidrosis and significantly improve the quality of life for patients. Just like botulinum toxin for wrinkles, the injections for hyperhidrosis will eventually wear off. The effects typically last anywhere between 4 and 12 months but will vary based on the location injected and the individual patient.
While these are the two most common uses for treating dermatologic conditions, there are many other uses for Botox in other specialties. Many studies are in the pipeline to test out new indications for the drug, and several other companies have or are bringing their own versions of botulinum toxin, be sure to visit your dermatologist to learn more about potential treatment options available.

There is nothing worse than being sick while traveling, and many a travel-related illness can be avoided (or at least mitigated). Please, for the love of all things good, take it from me. I’ve been there.
The advice in this post has come from over a decade of full-time travel, often learning the hard way; lessons learned in seemingly innocuous places, as well as truly inhospitable environments. Here’s how I survived (at times, barely).
It’s all about prevention.
In this guide I lay out the exact process for staying healthy while traveling, and preventing nasty things from happening. Because when icky stuff strikes, your budget – as well as your trip – may well be blown.
So let’s make sure icky stuff doesn’t strike, shall we? Let’s get started.
MY TRAVEL MEDICAL KIT
Got a Weird Skin Thing? Here’s What to Do.
Goodness knows, over the years I’ve had a ton of weird skin things. From heat rashes, to bug bites, to allergic reactions and more, skin disturbances can range from mild to severe, and non-serious to life-threatening.
Problem is, when you’re off in the boonies somewhere you don’t speak the language, how do you know?
When I was in Australia, I got 37 spider bites in one fateful night. They looked like they were healing up nicely, until two weeks later when they exploded (literally – it was gross). I asked a pharmacist to look at the carnage; they told me I needed to go to the hospital.
I might have been able to avoid that hospital trip if I had known about Aysa.
Aysa is a free app that is built using AI and the expertise of over 47,000 physicians and nurses. It’s so simple – you just take a picture of your skin condition. The app asks a few follow up questions and gives you a list of possible conditions and treatments. While it’s not a substitute for an in-person medical diagnosis, it is a great preventative health tool that just may help you nip a skin problem in the bud – before it becomes serious.
Perhaps if I had used Aysa when I was in Australia, I’d have learned that some antibiotic cream would have prevented the all-out infection I ended up with.

According to recent studies, nearly two-thirds of U.S. travelers rely on smartphone apps to enhance their travels.
- 61% have booked and paid for travel through their smartphone
- 65% want real-time flight alerts throughout the journey
- 54% prefer to use an app to add booking extras on-the-go
Would you believe I started traveling full-time before smartphones were really common? (Gosh, that dates me).
Having said that, I would be lost without my smartphone now. With all my years on the road, I’ve harnessed my smartphone to make travel easier, faster, cheaper, and more comfortable.
On the Go Apps
Skin Condition Questions? AI-Inspired Answers with Ask Aysa
I recently discoverd this app, and now it’s on my phone both on the road and at home. Using the expertise of over 47,000 physicians and nurses along with AI technology, this app is pretty revolutionary.
On the road, it’s so easy to have a “skin thing” – be it inflammation, bumps, flakes, or something else entirely.
Is it serious or not? You sure don’t want to ruin your trip by sitting in the emergency room unnecessarily; then again you don’t want to ignore a problem that becomes serious as a result (trust me; I’ve done both).
That is where Aysa comes in. Simply take a picture of your skin condition, answer the follow up questions, and Aysa will analyze your photo and give you personalized guidance. While it’s not a diagnosis tool per se, it may help put your mind at ease, or preventatively treat a little problem before it becomes a big one (or alert you to something that may require medical attention).
It’s a great travel app, because on the road, you might not be in easy distance of medical care, or even anybody who speaks English. Aysa is my first line of defence when I have an abnormality on my skin.
In honor of Skin Cancer Awareness Month, we wanted to take this opportunity to provide helpful information on how to prevent melanoma. Skin cancer is the most common of all cancers.1 Although melanoma is the least common of skin cancers, it causes the most skin cancer deaths by far. The good news is that if it is recognized early, it can be successfully treated.
Here are three ways you can help prevent melanoma:
Know Your Risk Factors
It is estimated that in 2019, 7,230 people are expected to die of melanoma.1 Though the disease can affect anyone, increased risk factors2 include:
- A family history of melanoma – If someone in your family had melanoma, it increases your risk 10-fold.
- Fair skin, light eyes, and a tendency to freckle – The risk of getting melanoma is 1 in 50 for Caucasians, 1 in 200 for Hispanics, and 1 in 1,000 for people of African descent.
- A large number of moles, especially unusual appearing moles.
- History of frequent sun exposure, especially in childhood.
- History of sunburns.
- Decreased immune system, such as transplant patients and patients with HIV/AIDS.
Though melanoma is the deadliest skin cancer, it is highly treatable when caught early.3 The best way to protect yourself is to perform self-exams. The warning signs are known as the ABCDEs of melanoma.2
- A – Asymmetry: One-half of the mole does not look like the other half.
- B – Border: The outline of the mole is irregular.
- C – Color: More than one color can be seen, such as brown, black, red, blue, and white.
- D – Diameter: A mole larger than 6 mm (1/4 inch), which is roughly the size of a pencil eraser.
- E – Evolving: Changes in the mole over time.
Self-exams should be performed once a month in a well-lit area after a shower or bath. Using a mirror can be helpful for difficult-to-see areas of the skin.
Contact your doctor if you identify a suspicious mole or other skin mark!
Avoid Sun Exposure & Don’t Forget Your Sunscreen
UV sun exposure is another huge risk factor for developing melanoma. In fact, nearly 90% of melanomas are thought to be caused by UV light and sunlight.4 Sunburn also plays a huge role in increasing the chances for the disease. One blistering sunburn can more than double a person’s chance of developing melanoma later in life. Be sure to have proper SPF coverage when you are in the sun, and avoid tanning beds at all costs.
When it comes to a suspicious mole or other skin mark, it is always recommended to contact your dermatologist or primary care physician as soon as possible.

ROCHESTER, NY (April 24, 2019)
In a survey of more than 1,500 U.S. millennials, 7 in 10 say skin damage is a significant concern for them. Yet when it comes to skin care and sun precautions, their everyday practices suggest a different attitude. A new poll sponsored by the developers of Aysa, an artificial intelligence-driven symptom checker app, aimed to uncover millennial attitudes and habits when it comes to protecting their skin – and here’s what it found.
Although 70% of millennials surveyed say they are concerned about skin damage from the sun, only 14% use sunscreen every day – despite the fact that sunscreen is widely known to be the best protector against the sun’s ultraviolet (UV) rays. According to the American Academy of Dermatology (AAD), sunscreen should be used every day, even if it is cloudy, as 80 percent of the sun’s rays can penetrate skin on those days. Nevertheless, 4 in 10 millennials surveyed only used sunscreen when they expected to be spending time in the sun. Fortunately, when millennials do use sunscreen, 78% use sunscreen with a sun protection factor (SPF) of 30 or higher (as recommended by the AAD).
“Dermatologists are seeing a concerning rise in skin cancer among young people and continued lack of precaution,” says Dr. Art Papier, dermatologist and CEO of Aysa’s parent company, VisualDx. “Skin cancer is the most common cancer in the United States, and melanoma rates continue to increase rapidly.” In fact, 1 in 5 Americans will be diagnosed with skin cancer in their lifetime, and men and women with a history of nonmelanoma skin cancer are at a higher risk of developing melanoma.
While 25% of millennials surveyed acknowledged a family history of skin cancer, of this group, 43% have never seen a dermatologist for a routine checkup. This is concerning because, as Dr. Papier notes, “Individuals, regardless of age, with a family history of skin cancer should be evaluated by a dermatologist and then see a dermatologist yearly for a full body scan if their risk profile is high.”
In 2017, the average wait time in metro areas to see a dermatologist for a routine skin exam was 32 days, which could explain why millennials – even those with a family history of skin cancer – are not making appointments with dermatologists. “Access is a concern in the field of dermatology,” Papier adds.
Of the millennials surveyed, 45% noted that they are prone to develop freckles and moles from sun exposure. This is a risk factor for skin cancer, and yet nearly 20% of these respondents said they do not know what an abnormal freckle or mole looks like. “Part of the reason for developing Aysa was to give individuals tools for understanding their skin issues at home,” explains Dr. Papier.
Users of the Aysa app can take or select a picture of a rash or skin lesion, and through machine learning and artificial intelligence, Aysa is able to analyze the photo and provide guidance on next steps, whether trying an over-the-counter cream or ointment, making an appointment with a dermatologist, or seeking immediate medical attention from an emergency room. Dr. Papier says, “We want to do a better job of educating people to help them make good health decisions.”
The findings are based on a Pollfish survey of more than 1,500 millennials in the United States.
The US Food and Drug Administration wants to test your sunscreen; should you be concerned?
Whether you slather on lotion or mist yourself with sprays, sunscreen is an important tool to protect your skin from the sun. This tool is actually an over-the-counter drug that the FDA regulates, and it does contain chemicals. Now, the agency wants more testing and data on what goes into your sunscreen.
What is considered safe? Should I check my label?
There are 16 active ingredients in sunscreen that the FDA can classify.1 Two ingredients (titanium dioxide and zinc oxide) are considered safe and effective. Two others (PABA and tolamine salicylate) are not safe and effective. Don’t worry, though – you don’t have to check your sunscreen label for PABA and tolamine salicylate, because they are banned already from sunscreens sold in the United States.2
As for the other 12 ingredients, the FDA wants more information before coming to a definite conclusion, which is why they’ve proposed more testing.
If my sunscreen has any of the 12 ingredients, should I throw it out?
Absolutely not. These ingredients have been in sunscreen for years. The FDA isn’t saying those ingredients aren’t safe; the agency just wants to be thorough. In fact, in the recent proposal, the FDA recommends continuing to use the sunscreen you have.
When will this testing take place?
This is still a proposal. The FDA guidelines are open for comment until the end of May. Then, the agency has until the end of November to send the proposal to Congress. If approved, testing could take years.
What should I do in the meantime?
Practice good sun protection (American Academy of Dermatology recommendations):
- Seek shade.
- Dress to protect yourself from the sun.
- Apply sunscreen to skin that isn’t covered by clothing with SPF 30 or higher.
The American Academy of Dermatology has a number of resources for you to check out, including How to Select Sunscreen and How to Apply. If you have any other questions or concerns, check with a board-certified dermatologist.

It’s no secret that tanning of any kind is bad for your health. According to the Melanoma Research Foundation1, using tanning beds before age 30 increases your risk of developing melanoma by 75 percent. In fact, the World Health Organization’s International Agency for Research on Cancer classifies tanning beds in the same category as other hazardous substances such as asbestos and plutonium. So, what are you to do if you still want that sun-kissed glow without the health risks? Here are a few sunless alternatives to tanning beds:
Most sunless tanners use the coloring agent DHA (dihydroxyacetone) to produce a darker skin color2. This ingredient causes a reaction involving the outermost, dead cell layer of the skin. Combining with the skin’s amino acids, it results in a “tan” that is much safer than a UV tan.
A large concern with sunless tanning is that a fake tan might leave your skin looking unnatural. However, if done right, a fake tan can look just like the real thing. Here are a few tips from Allure3 on how to prepare for your spray tan and keep it natural looking and long-lasting:
- Prepare yourself. The morning before your appointment, use a nonoily scrub to exfoliate the skin, and coat scabs and scars with Vaseline.
- If you use a retinoid or take Accutane, talk to your doctor about how this might affect your spray tan results.
- If you’re using a spray tan booth, put a light layer of lotion on the soles of your feet, between your toes and fingers, and on your palms, knees, and elbows. This will help ensure a more even tan.
- Avoid letting your skin get wet for eight hours and exfoliating for at least a week.
- Moisturize generously after you shower.
At-home tanning products come in many forms: lotions, towelettes, and creams to name a few! With so many choices, it can be intimidating and difficult to figure out which sunless tanning method is the best. WebMD has a helpful list of different types of self-tanning and what each is best for4:
- Self-tanning moisturizers: With a lower concentration of dihydroxyacetone (DHA), the active ingredient in sunless tanners, these gradually build a sun-kissed glow with daily use.
Best for: Achieving just a hint of color; a good starting step for novice self-tanners.
- Tanning towelettes: Presoaked with self-tanner, these sheets just need to be unfolded and swiped across skin for an even glow.
Best for: Keeping up your glow on vacation. These pads are stress-free. “It’s almost impossible to apply too much product with tanning wipes,” says Tamar Vezirian, a New York makeup artist who runs a tanning salon and mobile tanning service. She’s helped some models in the Sports Illustrated swimsuit issue get their golden glow.
- Self-tanning lotions and creams: The workhorse of sunless tanning, these formulas are often tinted so you can see if you’ve missed any spots.
Best for: Both practiced and beginner tanners. Because these formulas don’t absorb into the skin instantly, you have a few extra seconds to blend.
- Sunless mousses and gels: Lightweight and fast drying, these formulas are easy to layer, so you can build coverage or customize for contouring.
Best for: Experienced self-tanners. You need to blend fast before the color is absorbed.
- Do-it-yourself tanning sprays: The fastest way to cover large areas. Technique matters: You need to apply evenly from about 6 inches away in a circular motion.
Best for: Hitting hard-to-reach areas like your back. “These dispense just a light mist of color so you can achieve results that are like an airbrushed tan,” Vezirian says.
The benefits of a sunless tan are immense. Choosing to avoid UV tanning will help avoid many skin issues such as wrinkles, age spots, premature aging, and skin cancer. Don’t fear the “fake” tan — embrace healthier skin.

What exactly is digital health? The scope and definition of digital health is broadening and now, it seems, digital health is essentially anything that isn’t a drug or traditional medical device. It encompasses hardware (mobile phones, wearable sensors), software (AI, machine learning, mobile phone apps), and digital communication platforms (telemedicine, text, email) to improve health.
For challenging rashes and inflammatory skin diseases, VisualDx released a consumer app in 2018 called Aysa that uses machine learning to identify inflammatory skin conditions and make preliminary recommendations for self-help and treatment. These innovations represent important examples of how digital health is impacting dermatology.
