"i&#039;m 28 years old and i had pretty good until up until i took hormonal birth control 3 years ago and i am still trying to repair the damage to my skin. i&#039;ve been using a combination of benzoyl peroxide .25% cream in the morning on cleansed skin and trentinoin .05% cream (not the gel) before bed. my skin is very fair and sensitive but it&#039;s finally looking better after 2 weeks. so far i&#039;ve experienced mild purging by the chin and cheek but they are not the huge cystic pimples i used to get before. i think the peeling and redness is worth clear skin in the end."
