I'm in a similar situation as you, so I don't have much advice to give, but I wanted to let you know you're not alone! I'm going into my 5th week and my skin is maybe even worse than when I started, very red and painful and dry I'm also close to quitting but I've seen some people say that weeks 4-6 are the worst and that things get better after that... So I guess I might as well keep doing it since the alternative is doing nothing, which has a lower chance of working.
You should consider adding jojoba oil into The Regimen at this point. If your skin is dry and red just add a few drops of the jojoba oil into the palm of your hand and mix it in with the moisturizer and that will really help with the redness and dry skin.
