Any suggestions for products that work to get rid of keratosis pilaris?
If your condition is serious/ truly bothers you, it's best to talk to a derm and potentially get a prescription for most effective treatment. In terms of cosmetic skincare, you can try exfoliants: AHAs, salicylic acid, PHAs.
Please do not overdo it: the last thing you want is irritation (it can lead to pigmentation and worsen the condition overall). You should also use a daily sunscreen.
First Aid Beauty has a KP scrub that works well. The best things are to hydrate and exfoliate (both manually and topically with AHA/BHA laden body scrubs and creams).
