How long should I stick to a product until I give up on it?
For the past 2 weeks i have been using 0.1% tretinoin on my upper arms and calves for my sever pigmented kp. I have been doing it every other day and plan to start everyday in the next week. Ik that i am far from giving up on this and would like to try for at least 2 months but im curious, how long do people suggest we stick to a product for kp. Id hate to be wasting my time on a treatment that won't work. The tret hasnt done much for my kp, sometimes it looks better but I feel like its just lighting. It's understandable that it'll take a while for me given that my kp is years of hyperpigmentation on my arms.
