Brightens skin
It absorbs quickly and gives a noticeable glow. My skin looked brighter and more even after consistent use, and it didn't feel sticky or irritating.
Great consistency
a refreshing ampoule to brighten your skin. Feels nice to my dry skin and can use it day and night. Better to patch test.
Liking it
I am liking this serum so far. I usually press it on my skin and it does leave a bit of sticky residue. I would recommend following it with a hydrating face cream.
Brightening
I use Vitamin C every single day and this one didn't disappoint. I like that it's not overly greasy so it sinks into the skin. It is on the stronger side so I'd suggest to use every other day at first if you're sensitive. This has been great for brightening my skin. I haven't noticed any lessening of older dark spots but it does help with new spots. Other skincare layers nicely overtop.
Works great!
Works for me! I'm usually on the more sensitive side so I'm always careful about introducing actives to my skin, but my skin loves this! Would recommend to people who have sensitive skin but is interested in trying out vit c serum
