Tightlining eyeliner makeup is popular. The tissue between the lashes and the waterline is covered with makeup to accent the eyes. There is a downside to consistently applying makeup to this area. Debris at the base of the eyelashes affects oil production. Using eye pencils, eyeliner, mascara, eye cream, and shadows with glitters in this area causes them to be blocked. This area is called the Meibomian glands. It opens out onto the lid. This water line can get irritated and cause dry eye syndrome and blepharitis. Your optometrist has treatments for it.
What is MGB?
Meibomian gland dysfunction (MGD) occurs when the meibomian glands don’t produce enough oil (meibum) or are of poor quality.
Nutritional Support for MGB
Eat more fish, walnuts, greens, and eggs or taking omega-3 fatty acids supplements can help.
Diseases that can cause MGD
Rosacea, Sjogren’s Syndrome, Lupus and Rheumatoid Arthritis and other autoimmune diseases can increase the risk for Meibomian gland dysfunction.
