I live in the south and avoid the sun as much as possible. However, I do have to go into the sun (of course with sunscreen).. yard work, picnics, pool sometimes,etc. I wish I could live a vampire life like my esthetician commands- - impossible! I wear sunscreen everyday and all the time. I use Tretinoin every other night to assist with some sun damage. Should I discontinue using Tretinoin cream in the summer? Will the use cause more sun damage even with sunscreen?
