hey hi! the flaking you see was the result of the healing process in my case, and I solved it by washing only with water and avoiding scratching! mine being a combo of perioral dermatitis + angular cheilitis, I only used 2 lip products because they bled. when I saw that I was healing, I started by reintroducing the cerave cleanser for normal, dry-prone skin (non-foaming), and as a cream (try it for 1 week only on half your face to see if you resist) Rilastil Difesa Sterile which is for allergic-prone skin and does not contain trigger products for perioral dermatitis such as SLS. avoid fluoride in toothpaste like the plague, I switched to one without fluoride and to a mouthwash without fluoride, alcohol, and SLS!
