I'm not going to lie to you: This serum is an odd reddish liquid, and smells like ferment and Teryaki sauce.
It does, however, make for AMAZING skin! Trust Avance!
My skin was bright, even, happy and clear.
I do recommend putting it on at least 20 minutes before going to bed, just so your pillows don't pick up the scent. But it is worth it! Very worth it.
