In my opinion, we should know what blepharitis is. Blepharitis is an inflammation of the eyelids causing red, irritated, itchy eyelids and the formation of dandruff-like scales on eyelashes. The real reason of blepharitis has not been confirmed by now. As far as i can see, Seborrheic dermatitis, a bacterial infection, Rosacea, Allergies, Eyelash mites or lice can be consisted in the reasons of blepharitis. Makeup can be an allergic reaction to the eyelid and cause blepharitis. However, you don't need to worry about it for it's not permanent. There are some treatment options for blepharitis, keeping the eyes clean, using antibiotic creams and steroid eye drops. In so doing, the blepharitis will disappear gradually. Therefore, don't worry about it. It's ok, baby!
