2. Reaction to Makeup
Another common cause of blepharitis is a reaction to makeup. If you wear makeup around the eyes as is very common, then this can make its way into the pores of the skin, the hair follicles, or the meibomian glands. What’s more, is that this can have a reaction directly with the skin itself.
An allergic reaction effectively causes the body to act as though it has an infection. It thinks that something dangerous has entered the system and then essentially ‘overreacts’ by ramping up the immune system and causing the same swelling, redness, and streaming. All of this is designed to drive out the substance.
Allergic reactions to makeup are common, seeing as these products often use a lot of harsh and unnatural ingredients.
