Anyone who's spent hours scrolling SkinTok knows the drill: Someone swears an ingredient changed their life, so you buy it, but it doesn’t even come close to changing yours. That's the frustration that Cottonball, a new prescription-grade, personalized skin-care brand, is betting it can solve. Instead of investing your time and money in trial-and-error, you fill out a quiz, a real dermatologist reviews your answers, and a licensed pharmacy compounds a cream just for you. I signed up to see what the hype was about, and here’s what I know so far.
The Quiz
More like an intake form at a dermatologist’s office, this quick yet comprehensive questionnaire goes beyond the usual multiple-choice, “skin type” questions, and focuses more on your concerns and how much they bother you. It also wants to know about your sensitivities, allergies, the climate you live in and past skin issues.
Another piece of the puzzle the brand considers is your current skin-care routine, and you’re prompted to choose specific products you use from a drop-down menu. The drop-down found everything in my daily lineup except one moisturizer, which wasn’t a problem because I just selected another in its place. (I’m constantly testing products, so my routine isn’t static anyway.) It asks this to make sure that whatever the derm prescribes for you doesn’t clash (or duplicate) what you’re already using.
Uploading a makeup-free selfie is optional, though of course I did because I wanted to see how it viewed my skin. It could “see” my lines and wrinkles (humbling), so we were aligned on my primary concern. One thing that surprised me a bit was that it also detected under-eye dark circles and/or puffiness, which is not something I could see in my picture and not something I consider a big concern. Nonetheless, I didn’t take it personally. I appreciate a thorough exam.

The Formula
I was prescribed a custom-blended formula called VX.2, which included tretinoin, niacinamide, Matrixyl 3000, hyaluronic acid and provitamin B5, based on my primary concerns: lines and wrinkles, a little bit of redness and visible pores. Cottonball guarantees that orders will be reviewed by a dermatologist (in my case, it was Natick, MA dermatologist Michael Krathen, MD) within 24 hours, but in most cases it will be much sooner, like an hour or two. The brand tells me that if there are concerns based on your quiz results, or about the recommended product, the doctor will request additional information, a picture or a virtual consultation. If everything is status quo, everything will move forward quickly.
Other dermatologist-favorite ingredients you might see in your formula, depending on your concerns, are hydroquinone and azelaic acid, dosed in quantities you can’t get over the counter. If your quiz flagged that you were sensitive to something or had a bad reaction in the past, the algorithm takes that into account.
Each of the six formulas is mixed in small batches at a licensed pharmacy and shares a single base to which the actives are added. Developed by cosmetic chemist Ron Robinson—he’s the brains behind Hailey Bieber’s rhode, his own brand BeautyStat and many others, and a friend of NewBeauty—this base is the foundation for all the formulas, which target everything from signs of aging and wrinkles to dark spots, brightening, under-eye concerns, neck care and more. I love that Cottonball doesn’t sell a single “custom serum,” but rather this small, focused lineup of treatments that are each built around a core concern and individually tailored to your quiz answers.
As far as cost, mine is $70 per month, and there’s a 30-percent discount if you purchase a three-month supply. My two-month option would have been $90 per month. The brand offers free two-day shipping as well.
What Happens When You Get Your Product
Once you receive your blend, Cottonball says you can message its support team 24-7 with any questions, and “as your skin changes, your formula changes with it.” If the strength of your actives needs to be adjusted, they will make it happen, and quickly. Another thing I really like and appreciate is that the brand shows you where your new product fits into your current skin-care routine, based on the steps and products you included during the quiz. Mine is meant to be applied after my other serums and before my night cream.
The Bottom Line
If you’ve been curious about prescription skin care, and particularly heavy-hitting ingredients like tretinoin or hydroquinone, but don’t have time for an in-office visit, this is the next best thing. I can’t imagine you won’t be satisfied with your healthy, glowing skin, but if you aren’t, there’s also a 90-day money-back guarantee.
