Who among us has not, in a moment of panic or curiosity, consulted the internet in search of solutions to a medical ailment?<\/p>\n
Increasingly, people are turning to AI for health advice, and skincare is no exception. Purpose-built apps promise to identify that rash, while people are sending selfies to AI chatbots seeking \u201cfull skincare analysis\u201d and personalised regimens of treatments. On Reddit forums, people post before and after shots of the results from their AI-recommended skin routines.<\/p>\n
Given the significant cost of seeing a dermatologist \u2013 about $230 out of pocket in Australia, on average, it\u2019s no wonder some are taking skincare into their own hands by using AI as a tool. But too often the advice these chatbots provide isn\u2019t spot on.<\/p>\n
\u201cI can understand the urge to upload photos,\u201d says Dr Michelle Wong, a cosmetic chemist and science educator who runs Lab Muffin Beauty Science. But she cites the sci-fi writer Ted Chiang, who once described the output of ChatGPT \u201cas a blurry Jpeg of all the text on the web\u201d.<\/p>\n
\u201cIf you keep that in mind, I guess you can avoid the pitfalls,\u201d says Wong, who has warned of AI slop worsening scientific misinformation. \u201cMost of the time you don\u2019t see what sources they\u2019re using\u201d \u2013 whether chatbots have pulled skincare information from user-generated forums, dermatology websites or ill-evidenced blogs.<\/p>\n
In the last six months Wong has come across people who were told by chatbots to use multiple skin products with the same active ingredient, such as vitamin A. Others \u201cupload their routine and ask for what order to use [products] in\u201d, to be given a \u201cweird order \u2013 like, it tells you to use cleanser after serum, or sunscreen before a serum\u201d.<\/p>\n
In other instances, chatbots have advised consumers to use products that don\u2019t exist, or products that supposedly do not contain an allergenic ingredient but actually do. \u201cThey\u2019re very confident liars,\u201d Wong says. \u201cTry to remember it doesn\u2019t have a brain.\u201d<\/p>\n
She cites previous research showing that an image-classification AI mistakenly identified rulers as a marker of skin cancer, because in the training data images of lesions with rulers next to them were more likely to be malignant.<\/p>\n
For specific conditions, consulting a reputable dermatology website, such as DermNet, which has a large repository of skin images, is a \u201cmuch better place to explore\u201d than turning to AI, she says.<\/p>\n
Consulting AI can produce its own problems. Dr Anita Lasocki, a dermatologist and practice principal at South Road Dermatology in Melbourne, has seen patients develop skin problems as result of treatments suggested by chatbots.<\/p>\n
\u201cMost commonly I see irritant contact dermatitis or a flare-up of rosacea, where patients have layered too many steps or active ingredients into their skincare routine \u2013 retinoids, exfoliating acids, vitamin C, overly rich moisturisers and so on \u2013 in the hope it would help their problem, but it ends up fuelling it or creating a new complication altogether.\u201d<\/p>\n
She adds: \u201cThe core issue is that an AI chatbot can\u2019t provide an accurate diagnosis. Some of the general principles it suggests might be reasonable, but the specific advice may not apply to the person asking. As a result, patients often spend significant time and money on products or treatments that were never indicated for their actual problem.\u201d<\/p>\n
Associate Prof Deshan Sebaratnam, a dermatologist at the Skin Hospital in Sydney, agrees. \u201cThere are over 3,000 skin conditions in dermatology, and AI is not good at separating these at present,\u201d he says.<\/p>\n
For example, he says, a dry scaly rash could be eczema or psoriasis, which is treated with anti-inflammatories; ringworm or scabies \u2013 treated with antimicrobials; or less common conditions such as lupus or cutaneous lymphoma, a type of blood cancer involving the skin. Chatbots can\u2019t carry out tests like skin swabs, scrapings or biopsies that may be required for accurate diagnosis.<\/p>\n
In addition, he points out, \u201cmost medical images used for teaching are of white-skinned people, so AI is also not well equipped to make diagnoses in skin of colour when there is less good reference material for it to learn from\u201d.<\/p>\n
Consulting AI chatbots for skin advice may partly be driven by the significant cost of seeing a dermatologist and long wait times. \u201cThere is a worldwide shortage of dermatologists to meet the burden of skin disease, but this is particularly true in Australia,\u201d Sebaratnam says. \u201cPublic dermatology appointments have long wait lists, but so do private dermatologists, and appointments usually cost hundreds out of pocket.\u201d<\/p>\n
\u201cPeople could use AI to brainstorm problems, but at the end of day don\u2019t put your trust in it,\u201d Sebaratnam says. \u201cNo one understands your skin like a dermatologist.\u201d<\/p>\n
For those seeking a basic skincare routine, \u201csimplicity is best\u201d, Lasocki says. \u201cIn the morning: a cleanser may or may not be necessary. A light moisturiser is typically desired, particularly in dry weather or cooler climates. And a non-negotiable in Australia is SPF 50+ sunscreen on the face, year-round. Some patients like to add an antioxidant vitamin C serum underneath their sunscreen \u2013 it\u2019s not compulsory, and in certain skin conditions it can actually be aggravating.\u201d<\/p>\n
She suggests a gentle cleanser in the evening. \u201cMost can be bought at supermarkets or pharmacies for a reasonable price \u2013 look for one that\u2019s fragrance-free, non-foaming, soap-free, and avoids essential oils. A simple moisturiser afterwards is sufficient for most people. For those with an intact skin barrier who want to optimise further, an over-the-counter or prescription retinol can be added \u2013 but it should be introduced slowly and carefully to minimise irritation.<\/p>\n
\u201cNot every patient needs active ingredients. For many, a moisturiser and sunscreen in the morning, and a cleanser and moisturiser at night, is all that\u2019s required.\u201d<\/p>\n
Another good rule of thumb is to apply products in order of thinnest to thickest, Wong says: serums before moisturisers, sunscreen last, and make up on top. \u201cThe instructions on the packaging \u2013 that\u2019s always going to override what [a chatbot] tells you.\u201d<\/p>\n
