4 Find The Allergen
Many cases of blepharitis are caused by some kind of allergic reaction. This may be a makeup product, a skincare product, or any number of other things you use on your face. The skin here is extremely sensitive and therefore can react badly to seemingly innocuous things.
The aim then is to return to basics and to use as simple a regime as possible. Try just using water and if that clears up the problem, then you can gradually reintroduce items one at a time until you find the culprit.
Another point to consider is that blepharitis is very often caused by allergies to dander and pollen. These can likewise irritate the area and cause many of the same symptoms. Using antihistamines may be useful in this scenario.
