The first week I had no side effects at all, then half way through the second week, my skin suddenly became super oily, and then the very next day it went dry.

So for me, the dryness side effects came very suddenly during week 2.

20mg is a pretty low dose so it may take a few weeks. Dry lips will probably be your first side effect.

oh buckle your seat belts- the first week i remember i just waited around and was like "oh wow this is going to be an easy treatment"- second- to third week i was like... why did i agree to this... Anyways- im on month err 5 right now or 4 i cant rmemeber! ahhh. anyways stick with it! it gets better after month 2 and a half! trust me. also after you wash your face- you skin should not feel very tight- if it is your cleanser is tooo harsh.

Best friends- CeraVe hydrating Cleanser + CeraVe Lotion (in the tube) you are gonna thank mee

I think I jinxed myself. My lips have been soooooo dry today. It begins now, right?
