What it is: A serum that boosts overall skin conditions, improving pores, sebum, firmness, fine lines, skin texture, skin tone and irritation.

What it does: The serum makes your skin soft and smooth and helps even out your skin tone and texture. It features a lightweight, nonsticky texture that absorbs quickly. It's perfect for those with complex skin concerns that want to improve overall skin conditions at once. It is the ideal first-step skin booster that can be paired with other products.

How to use: After cleansing you may use this serum as the first step of skin care. Spread the serum on the entire face and you may apply several times to amplify the effect of the next serum or ampoule

Plump and Hydrating
[This review was collected as part of a promotion.] I loved this skin booster! It made my skin feel more plump and hydrated. I used this at night with my nighttime skin care routine so I am not sure how it would do under makeup.

Amazing serum for acne skin.
[This review was collected as part of a promotion.] My acne skin really enjoyed this serum. After weeks of consistent use, my skin genuinely felt smoother, more hydrated, and looked healthier overall. I didn’t have a good experience with other cosrx products, however this serum did wonders for my skin.

[This review was collected as part of a promotion.] Love the hyaluronic acid in this serum. The serum appearance itself is very lightweight & thin but it is very hydrating and brightening on the skin. Nice all in one serum for those who don’t want a 20 step skincare routine.
