Pleasant hydrating serum
4/17/2026

This serum is suitable for all skin types. It hydrates perfectly and is suitable as a first serum before thicker consistencies (as a base for hydration). It does not contain perfume or other potential allergens - suitable even for sensitive skin.

This serum is also great for combination skin, moisturizing well without clogging or weighing down the skin. It absorbs quickly and leaves a smoothing effect and a healthy glow. A very effective, lightweight product for daily care.

I use the COSRX The Hyaluronic Acid 3 Serum and I am very satisfied. I have dry skin, so good hydration is critical for me — and this product did a great job. After using it, my skin became softer, moisturized, and looked healthier. I especially liked that the serum doesn’t leave a sticky feeling, absorbs quickly, and feels comfortable on my face. The only downside is that the jar is gone 😊 I will definitely buy more!

Very pleasant, quickly absorbed serum, does not leave the skin greasy. In the morning I see that the skin is nicely hydrated and smooth. My friend also uses it and he is also satisfied.

I bought this serum just to try it out, because I use other products from this brand in my skincare. I am pleasantly surprised. The serum is not heavy on the skin at all, it hydrates wonderfully, my skin does not feel dry at all and after applying it to my face my face feels smooth, unified and extremely pleasant to the touch. In combination with the cream, this serum is simply great. I recommend it.
