I've been doing a mix of dermapen and TCA Cross (100% performed by my derm) to reduce my indented facial scars from cyctic acne in my 20s and chicken pox as a teen. I don't use any actives until a few days after either treatment, fyi. I'm a pale redhead with pretty sensitive skin, so it took me awhile to work my way up to using 0.1% Tretinoin every night. However I'd like to introduce the TNS Recovery Complex into my skincare routine, but am not sure how to do so. Any advice would be appreciated
