Post-acne marks almost gone
Three years carrying them. Two months with The Vitamin C 23 and they've faded a ton. The Ácido hialurónico combo is a winner.

My esthetician was shook
Showed her before/after with The Vitamin C 23 and she was floored. Said she'd never seen results like that without laser.

TikTok made me buy The Vitamin C 23
Saw The Vitamin C 23 four times in one afternoon and caved. Lasts forever and my friends stole two.

Good but not for me
The The Vitamin C 23 didn't irritate me, but I didn't see the change I hoped for in a month. Might need longer, but I'll move on.
