Vitamin C and Hyaluronic Acid

By Kiehl’s Education Team

Hyaluronic Acid and Vitamin C are both important ingredients that can deliver powerful support in our formulas. The former ingredient is often found in formulas that aim to hydrate skin, while the latter addresses skin radiance and even tone. How might the two ingredients work together in one skincare routine, and what are the best ways to use each respective ingredient for your skincare needs?


Vitamin C

Vitamin C is a powerful ingredient that can visibly improve deep lines, wrinkles, uneven skin texture, and dullness. It’s key to the production of collagen and elastin in the skin and is known to have an anti-aging effect.

Vitamin C can also help reduce the appearance of skin-aging damage caused by UV radiation and free radicals.

Hyaluronic Acid

Hyaluronic Acid is a potent anti-aging ingredient. Its benefits include replenishing skin to boost hydration, improving texture and decreasing the appearance of wrinkles to reveal a firmer, plumper complexion.

How Can You Use Hyaluronic Acid and Vitamin C In Your Routine?

Hyaluronic Acid and Vitamin C can complement each other when used in the same skincare routine. Together, our Powerful Line Reducing Serum and Ultra Pure High-Potency Serum 1.5% Hyaluronic Acid can visibly reduce wrinkles, improve skin brightness and hydration.

Our bestselling Powerful-Strength Vitamin C Serum is a multi-benefit serum that instantly smoothes skin texture and visibly reduces fine lines and wrinkles while improving the appearance of skin's radiance and texture. It also contains fragmented Hyaluronic Acid — a shorter-length Hyaluronic Acid that is better able to penetrate the surface layers of the skin. This allows for more moisture to be drawn into the epidermis, improving the appearance of fine lines, and smoothing out the look and feel of rough skin texture.

In terms of how best to incorporate both ingredients into your skincare routine, it’s important to layer them correctly for the most effective results. If you decide to use Hyaluronic Acid and Vitamin C separately, apply the formula that has the lighter consistency first, and then layer up to a thicker serum and moisturizer after.
