Questions about COSRX The Vitamin C 23 Serum 20g

Got questions? We’ve got answers!

Who is this vitamin C serum best for?

It suits people already comfortable with vitamin C who want a high-strength brightening serum for dull, uneven-looking skin. If your skin is very sensitive or new to vitamin C, you may want to start with a gentler, lower-strength option.

Does it tingle, and is that normal?

A potent vitamin C like this can cause a light tingle, especially at first. Introduce it slowly, patch test, and if it feels uncomfortable, use it less often or pair it with a moisturizer.

Does the COSRX Vitamin C 23 Serum have a scent?

No, there is no added fragrance in the ingredient list, so it is a good option if you prefer fragrance-free skincare.

How do I keep it from going off?

Vitamin C can oxidize over time, so store it somewhere cool, keep it out of direct light, and try to use it up within a couple of months of opening.

Where can I read COSRX The Vitamin C 23 Serum reviews, and is it authentic at C&C Canada?

Yes, C&C Canada stocks authentic COSRX stock, and you can check the star ratings and shopper reviews right on this product page before you buy.
