I'm going on a 4 day camping trip starting this thursday and i am contemplating not going due to my acne. I'm afraid that if i stop the use of my retin a for 4 days that my skin is going to breakout and I will lose the progress i have made ( my acne is by no means clear it just is not as severe as it used to be ). Is there anyway i could use the retin a while i am camping ? Or should i cancel the trip?
