As I understand it, oligopeptides are peptide chains made up of 4 to 25 amino acids. This explains why it isn't listed as a single ingredient in this serum. This is based on research and guesswork, and you should definitely not take my word for it. This serum is a bit pricy, but if the ingredients are as listed, it should help rebuild collagen in the skin. I've found a little goes a long way. If I use more than I should, it feels tacky to me, and I don't care for that sensation. While I can's say I have seen any tremendous improvement in my skin as yet, I will say this is non-irritating, even when used near my eyes, so that is important to me. I do feel like my "crows feet" are softened after a few weeks of use.

This serum repair renews and provides increased hydration and collagen. Lessons fine facial expression lines. Lovely product.
Soothing. No sensitivity issues.

This is a product I use after toner and before a moisturizer or cream. The amopoule spreads very nicely on skin and only a little is needed I noticed it would get stickier if I end up using more. Even without a moisturizer afterwards, there is definitely still a feeling that this is very hydrating and keeping skin plump. The dropper helps to limit how much is used. Considering the size of the bottle and cost, it seems to be a very good product worth the investment.

Heavy glass bottle but the serum smell is very medicine-like. It feels sticky when its drying and it does moisturize but I don't think its something i can keep using because my skin stayed sticky even after it'd been awhile since i applied it on.

This helps to repair the skin, increase hydration and collagen and improves the appearance of fine lines and wrinkles. It enhances volume and plumpness of the skin with Glycerin, Glycol, Hyaluronic Acid and Peptides. It has a beautiful texture that feels lightweight and absorbs beautifully.
