What the product description says
“- Hyaluronic Acid: Supports hydration and acts as a delivery system to enhance skin exposure to actives.”
Source: Sephora

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. The following ingredients in this product do the job: alanine, arginine.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: arginine, caprylyl glycol.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, dipeptide diaminobutyroyl benzylamide diacetate, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, palmitoyl tripeptide-38, pentapeptide-18, urea

  • Tessie· Oct 2023Recommends

    Possibly the best product out there if you're interested in trying peptides but not completely sold on them. It contains a combination of peptides that are among the ones that have a bit more evidence backing their effectiveness (e.g. Argireline, Matrixyl Synthe'6, Matrixyl 3000 & Syn-Ake) and also has good humectants, so even in the worst case scenario of the peptides not actually working in skin, at least you're getting a good hydrating serum at an overall affordable price. I have to note, however, that as for the Argireline's "botox-like" effects, I feel like I got better results when it comes to the vertical fine lines on my forehead with The Ordinary's Argireline 10% solution than with this.

  • Nehy06· Mar 2023Recommends

    Only thing it does for me is hydration. Maybe a little brighteness in the skin, but the effect is very slight. I do not see any difference after 1 bottle. Although, it hydratest, it is not iritating, no fragrance and absorbs quickly.

  • Skinaddict· Oct 2022Recommends

    Helped me a lot with hydration. I don't have aging skin (I'm 19), however acne treatments had dried out my skin so much, I was left with some dehydration lines on my forehead. This product did help a lot to make them not visible. Also, I've had some fine lines around my eyes and ever since I started the Buffet they are not noticeable at all (I also do under eye slugging -with Vaseline on top of the buffet- every night as I'm not prone to milia)
