This serum is amazing. I've been using it for a few years now and definitely won't be changing anytime soon. It leaves my skin glowy and soft. Definitely recommend.

The best vitamin c
This is my third bottle of this vitamin c. The best I have ever used! It's smells beautiful and goes on the skin like silk.

Underwhelming
I got this in the LF dermatological skincare box and was excited to try - but it’s been a bit underwhelming for me. I’ve used nearly all the bottle now and seen some brightness, but not nearly enough impact to justify what it would cost at full price. Also, the texture is a bit weird and sticky, which might be because I have combination skin
