Cu SkinCU Dr.Solution Niacin 10% Vitamin C Ampoule

This is the best niacinamide serum I've ever tried. It really evens out the texture and overall appearance of my skin. The texture is watery and doesn't leave any film behind at all. I'll definitely be repurchasing it a few more times.

It leaves your face very radiant and evens out your complexion. Vitamin C combined with niacinamide is simply a bomb for your skin. It doesn't clog pores. I recommend it.

This serum truly brightens discolorations, even the most blemished ones. It mattifies and doesn't clog the skin (it's non-comedogenic), absorbs quickly, and is fragrance-free. It doesn't leave you with a heavy, blemish-free effect, but it mattifies.

It makes your face very radiant and evens out the top of your face, and I have the impression that there is some kind of smoothing mask on my face. I always just took vitamin C, but this one in combination with niacinamide is just the bomb.

A great serum that regulates sebum and doesn't clog pores, one of the best for oily skin, I recommend it.

Good serum, my favorite serum with niacinamide. It really helps tighten pores and the result for me.

This product worked well for me; after 3 weeks of daily use, my pigmentation spots had lightened slightly. I recommend it.

A very good serum for brightening discolorations. Overall, it does a great job of brightening and evening out skin tone. The only thing that doesn't do much for lightening acne discolorations.

Great product

I like this ampoule. Liquid consistency, does not weigh down. Mattifies and reduces pores.
