Serum with peptides

Thin serum. Absorbs quickly into the skin. Leaves a pleasant texture and I like the result on my face! I use it in the morning before my moisturizer!

Great hydration

I have sensitive and sometimes reactive skin. After just a couple of days of use, I've noticed my skin is better: more hydrated and looking healthier. It absorbs really well, and I can then apply my moisturizer. It doesn't leave any shine; it leaves my skin feeling great.

I bought it by chance when the product was on sale. I've been using it for quite some time now. It leaves a moisturizing effect on the skin and absorbs immediately. It's not sticky. I have combination skin, and my skin doesn't feel greasy after using it.

The best thing with peptides I've ever had. Excellent consistency, suitable for oily skin too, instantly nourished skin. I recommend 👌👌

Light, absorbs quickly and I love peptides. It really fits into any routine. It can replace toner, but I personally use it after it because it also contains KH and I want to get the most out of it. This product is a staple in my morning and evening routine.

Great serum for daily care
3/12/2026

I've been using this serum for a while now and I'm very happy with it. The texture is quite runny, but that's precisely why it's so easy to apply to the face and very economical. My skin feels soft and comfortable afterwards. It hasn't caused any allergies or irritation for me. The bottle is practical and overall it's a great basic skincare product. 😊

The serum is very watery (it doesn't contain propanediol), and the name "booster" is more accurate. It works especially well for me when I'm choosing other active ingredients in my skincare routine but still want to "smuggle in" peptides. It boosts skin's hydration, which is clearly noticeable. It has a large capacity and is easy to apply, so I also apply it to my neck, décolletage, and even my hands.

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.
