Welcome to HCM
Coloring with dye is very common but it is allergy to the similar chemical dye hebal or dye always do a skin allergy test
if allergic donot use product it may be costly or cheap.
Any allergy and infection should be treated accordingly.
It is more important to have healthy skin and I would advise kindly consult a good Dermatologist
to if there is any other condition like diabetes
nned to be ruled out.,for beard a clean shave may be a option.
Take up healthy life style do exrcise daily and healthy and balanced diet will improve skin a lot good and do not use alcohol,take 7 hours of sound sleep.
Good Luck to you
