Keratin Lifts

I've been doing some research on lash lifts since I saw a little article about them on social media. It seems like a better option than lash extensions (was contemplating on them for a while) because of their low maintenance and cost value. The articles I've looked at are focused on keratin treatments and specifically done by a BH-based technician named Elysee using the YUMI formula. The keratin treatments argues that they have no parabens or ammonia products, which make them friendlier and safer. The three brands that are "safer" are YUMI, Elleebana (MSDS), and LVL. This blog talks about how these three are basically identical, just marketed in different countries.
