Vaseline can help with a number of dry eyelid conditions. People who notice that their skin is dry or irritated during the dry, cold winter months can use it to prevent moisture loss from the eyelids. Some people also use it as a moisturizer to reduce the risk of wrinkles, or as a supplement to traditional eye creams.
Some doctors also recommend Vaseline for specific dry eye conditions. It may help with blepharitis, which causes dry and irritated eyelids, as well as dysfunction in the meibomian glands that lubricate the eyes.
Petroleum jelly from Vaseline can also help keep wounds moist. This may help prevent scarring. The skin on the eyelids is very thin and has a higher risk of scarring with exposure to the sun.
Petroleum jelly is not really a moisturizer, like some lotions or serums. Instead, it creates a moisture barrier. This means that it prevents moisture from leaving the eyelids and can make it more difficult for moisture to get through. For this reason, it works best when a person applies it after other moisturizing products.
