What are mink lashes made of? The answer is that they are made from the hair of real mink. Real mink lashes are light, soft, fluffy and ultimately look more natural, matching the natural human lashes very closely. Mink lashes usually last longer because they are so light. The downside to this type of extension is that they are expensive. But again, due to the quality material and light weight of the lashes, mink lashes can be used over and over again!
