This TikTok on how to get glass skin is going viral (and it uses just four products)

As its name suggests, glass skin refers to an almost transparent complexion that resembles a reflective mirror. Like most innovative skincare trends, glass skin hails from Korea and made its first appearance in the beauty sphere in 2017 - and now it’s taking over TikTok. Achieving glass skin usually includes a multi-step skincare routine, but one TikTok user has shown how you can mimic its high shine by using makeup instead.
