Permissibility of making Masah of ones face for Wudhu if one has eczema

Aslm’alykum…i suffer from eczema which now has spread to my face…is it permissible for me to make masah on my face in wudhu until the problem subsides as water irritates it and makes it worse? If it is permissible than will my masah be valid if i have makeup on which doesnt get washed of due to the masah?jzk
