The product is decent, doesn't cause any allergic reactions, and absorbs quickly. However, I won't buy it again; I prefer the Mizon peptide serum.

I'm still looking for a peptide essence that works for me. It stings a little when you apply it, but it works well with other products. My skin is oily and sensitive.

Amazing product that can be used as a skin preparation before moisturizing cream for better absorption, but also on its own! It gives a very nice feeling of cleanliness and freshness and leaves a shine that makes the face look fresh.

The serum has a light consistency, absorbs well, is fragrance-free, which suits my sensitive skin. I am satisfied with it, it is good to use in both the morning and evening routine.

It's a good serum, more like an essence, quite thin, no spectacular results so far.

Wow effect 😍

I bought this serum at the recommendation of a friend and was delighted. It has a light consistency, isn't sticky, and doesn't leave a greasy residue. I've been using it for over six months and I can see the results. My discoloration has disappeared, and my skin is radiant.

Revelation!

This serum-essence from Cosrx is working great for me. I've already used half the bottle, but after just the first few days, I noticed my skin became firmer, soothed, and my pores had shrunk. It has a slightly watery consistency. It lasts a long time! 🩷
