Good product I bought a lot from stylekorean

Tried this product out because of Tina Tanaka Harris, and it works! Not harsh on the skin, but the sebum control and brightening effects can be seen after just a short period. Highly recommend adding it to your routine, and layering with other serums.

The best of the best! I really like it and will recommend to my friend ♥️

I use the product in the morning to brighten my skin for a day

I haven't tried the new version but if the brand keeps the same formula as the previous version, so i is a deserving serum with high content of niacinamide. Feeling good on the skin, quick absorption but not sticky or uncomfortable

Amazing Product! Must Try! Recommend to purchase

it work as it describe. function well.

It's just ok, doesn't irritate my skin but can't really tell if it has any effect.

I love Tiams vitamin B products. The toners have a nice slip, and the serums are not heavy and oily on my skin. Works very well.

This vitamin serum is super lightweight on the skin, it's non-scented and drys fast on the skin. I love it, makes my skin smoother and brighter.

I love this serum. Very good for uneven tone and texture and hyperpigmentation.
