I've reintroduced this powerful vitamin C serum back into my routine because my hyperpigmentation has re-emerged. After only a few weeks of use, the dark spots and uneven skin tone have already faded and are much less visible.

Gradually increasing the vitamin C concentration in my routine, I've tried various other serums before - this one is the most effective so far. I'm not sure if I should Show more

No irritation, no weird smell
I switched from Cosrx's Vitamin C 23 serum to this. I prefer this to Cosrx. It has no smell, no irritation and gentle to my skin. If you are a fan of Cosrx Vitamin C serum (but loathe the smell), you may want to try this too.
