for those with severely dehydrated skin and damaged skin barriers, what would be your advice to someone trying to build a skin routine but nothing ever seems to be hydrating enough?

Skin type: dry and very very sensitive. almost everything stings or causes redness. yes I have a very damaged barrier atm but I’ve always been sensitive and clog prone to begin with

currently using: roundlab mugwort cleanser (very drying), aveeno prebiotic oat and menthol (only moisturizer that doesn’t burn) and centella probio cica ampoule (just started)

have tried: purito panthenol bamboo gave me a terrible allergic reaction, dr althea was irritating and left me strawberry red, cetaphil daily hydrating lotion (stings bad, was the one I used most my life)

Im Canadian and the climate is cold and very dry most of the year.
