Hi,i am currently on 10mg/day of isotretinoin, no major side effects except dry lips and skin flakes around mouth and nose area. I live in a tropical country, am wondering if the followings are safe during my treatment: - Is it safe to use benzoyl peroxide topical 2.5% on acne spots? - Are Kojic Acid, Retinol and Arbutin serum (topical) safe? - Is manual extraction of comedones and soft chemical peeling safe? Thank you very much in advance.
