The Inkey menu 20% vi-ta-min C Serum

Despite my love for many The Inkey danh mục products, I was not a fan of their 20% vitamin C.

More watery and with 5% less Ascorbic Acid, Geek & Gorgeous use the same full bộ with vitamin E and Ferulic Acid that Timeless has. There is no Panthenol và more preservatives due to lớn the dropper bottle packaging as well as a slightly higher pH of around 3.4.I prefer the more watery texture of this one and, as it is easier to get and more affordable, will continue lớn repurchase Geek và Gorgeous.
