Hello. Im a 37 y/o male. I may have allergic contact derm on my face from years of facial products. (Wash and lotion) Its scales with no redness and extreme dryness after a rinse or shower. Its been chronic for 3 yrs. I stopped products a month ago. Its better but not gone. Scales are in my brows, around mouth facial hair, cheeks and eyelids. All where i used products. How long can it take to fully heal?
