Replenishing Eye Serum



Our eye serum protects against the degradation of elastin and collagen while simultaneously stimulating their production. This means it helps prevent the formation of lines, as well as smooth the appearance of existing ones. Unique to this formula is retinol in a concentration gentle enough for the under eye yet potent enough to create change without any irritation. 

You’ll find this serum lightweight and creamy as you smooth it on and you’ll notice a regeneration of the under eye over time: lines look smooth, texture is firm, and dark circles and puffiness disappear. We like to say it brightens your outlook.

Love the eye serum. Goes on smooth and easy. I have already seen visible lines diminish some. Hope for even more results in the future. Barbara

I'm still using my previous Replenishing Eye Serum and have not opened the new one. I like all of Dr. Koo's products.

Products are great, your skin absorbs the products, doesn’t just lay on the skin.
