As I've said from my previous posts that there are various ways of treating acnes. I recently just remembered my godmother who visited last year about tretinoin gel. She attested that tretinion works wonders for acne and that she is using it when a zit occurs in her face. She even recommended it to her sister and her sister's daughter. In fairness, they too have flawless face. Her sister even said she poured some tretinion solution to their astringent.
