What are lash extensions?
Eyelash extensions, also known as Semi-Permanent Eyelash Enhancements, or simply Lash Extensions, is the professional application of a single, or multiple, synthetic lashes applied to your natural eyelash using a fast-drying, semi-permanent glue, by a Licensed and Certified Lash Artist.
What are lash extensions made of?
There seems to be some confusion about the material that is most widely used to make eyelash extensions. People hear “mink lashes” and of course think of Minks being tortured and abused for their fur. While this is true in some parts of the world, it is most likely not what your local Lash Artist is using.
First, real mink lashes are expensive due to the methods to attain them, and therefore a limited supply is available. Second, real mink fur is not easy to work with because it is thinner and not as rigid as faux mink lashes. Third, real mink is not the most sanitary to use because it does come from an animal. Last, real mink does not have the best cost-value ratio due to the sourcing and production involved, and they must be curled by the client on a regular basis just to maintain the best look.
Millions of synthetic lashes, also known as faux mink, are manufactured in order to supply the booming eyelash enhancement industry, for semi-permanent lashes and for strip lashes. By using a more affordable and more readily available material, the only way to balance the supply and demand needed is to make them out of plastic, particularly PBT, or Polybutylene Terephthalate, which you can read more about here.
PBT maintains its shape and curl while also being strong but flexible enough to be comfortable on your eyes. It is also healthier to use near your eyes because it is not susceptible to holding germs or absorbing oils or dirt. With proper care, cleaning, and regular fills, your eyes and your extensions can live harmoniously for as long as you wish.
