  • Exfoliate your skin to stimulate more efficient delivery of skin renewal mechanisms, including higher levels of collagen production

This product works by delivering multiple functions infused in a single formulation. It facilitates exfoliation, faster skin regeneration and renewal, and better antioxidant protection — all thanks to Vitamin C, and to some extent, Adenosine.

Adenosine: Boosts your cellular energy, this ingredient is key to speedier repairs, regeneration, and renewal that, in turn, restores your skin’s overall health and normal functioning [2].

Glycerin: May help skin retains moisture while reducing inflammation but also can cause skin irritation to sensitive skin [3].

Pentylene Glycol: This ingredient is used in cosmetics and beauty products that is also secondarily used as a solvent and preservative. However, can cause skin irritation, dermatitis, and hives from too many mast skin cells [4].

Kiehl’s Powerful-Strength Line-Reducing Concentrate offers an additional way for you to address your aging skin problems using just 1 key ingredient, Vitamin C.

That means no more layering and lesser chances of encountering product reactions that can lead to skin irritations.

As we age the composition, texture and appearance of our skin changes. Signs of skin aging include wrinkles, fine lines, loss of moisture, uneven tone, and dull, tired-looking skin. There are countless anti-wrinkle creams on the market promising to make skin look and feel younger. Many anti-wrinkle creams promise everything short of a facelift or to provide the much sought after "fountain of youth". In reality most are just moisturizers marketed as anti-aging products.

Below you'll find some of the most effective wrinkle serum formulations on the market today, in our opinion:

"I'm a 32-year old professional actor and dancer. At my age getting jobs as a dancer gets more and more difficult. Because of this, I want to hide my real age as much as possible. That's why I started using Kollagen Intensiv. I'd heard about it before by good reputation, which is why I chose this specific cream. I concur that Kollagen Intensiv is an incredible anti-aging cream that really does work. My skin feels and looks amazing, and I could swear that I appear 10 years younger at least. I am so happy I found this product! It has done amazing things to my skin!- By Delilah

    Great Vitamin C Serum - kiehls fine line reducing serum
    Too early to tell. Been using the serum for about 2 weeks. It does seem to be breaking my forehead out. Will use entire bottle and make determination then if to continue with using.
