So I can use retin A no problem and have used for over a year ,built up to 0.1 three times a week , running low so used redermic R I bought ages ago but never used , woke up with a really sore peeling face :( cleansed as normal with cetaphil and sloughed off the flakes ! Covered in Nivea blue pot and even more peeling ! Washed off and covered in cetaphil cream !! Haven't left the house today ! 'My chin and between my eyes are bright red and sore !! Hope it calms down my Monday. Didn't expect that at all as I wouldn't have thought it was as strong .
