Who It’s For

All skin types as an essential part of your anti-aging regimen at every stage of aging for prevention and repair, especially of sun damage, pigmentation, and uneven skin tone. 

How It Works

This Vitamin C Serum stands alone among any other C Serum you’ve tried. It’s designed to deliver dramatic results, with a combination of three potent, stabilized forms of Vitamin C, perfectly paired with a cocktail of 22 additional active ingredients.

We begin with 20% Tetrahexyldecyl Ascorbate, 3% Magnesium Ascorbyl Phosphate, and 0.5% Ascorbyl Palmitate to create a glowing complexion without irritation, even for many sensitive skin types. Vitamin C combats the loss of collagen that comes with aging to leave skin firmer and less lined. In addition, it boosts your skin’s ability to produce collagen. Its proven antioxidant power protects skin from UV damage and environmental oxidation when used along with sun protective practices.

Phloretin enhances the penetration of all active ingredients making them even more effective, while also acting as a potent antioxidant in its own right. This flavonoid helps to even skin tone, while boosting the performance of other ingredients.

Hyperpigmentation, dullness, and rough texture all get a dose of serious work from ferulic acid, resveratrol, CoQ10, turmeric extract, and glutathione, which is considered one of the body’s most essential antioxidants for age repair and prevention. The synergy of all these active ingredients, and the many others that comprise this unparalleled formula, deliver noticeable improvements to the skin that have garnered media attention and a cult following of devoted users.

Loving the Vitamin C Daytime Serum!!
Just started using Kate Ryan products but very happy with results. My skin feels so much softer and brighter. I’ve also been impressed with the customer service and help I’ve needed!!

Must have!

As a busy mom of two littles, I rely on products that are effective and easy to use. The Vitamin C Daytime Repair Serum is an absolute staple in my routine. I love starting my day with this serum; it absorbs quickly and gives me a healthy, even glow.

Vitamin C daytime repair

I first tried this product last spring and then ran out. I went a few months without it and my skin really missed it! I recently reordered it and my skin looks more radiant and feels soft and healthy. Thank you! I will not let my supply get depleted again!

Every day serum

Searching for long time finding the enriched antioxidants serum and finally got this!
Love it!

Best Vit C Serum

This is the first vitcamin c serum I have been able to use consistently. I have sensitive skin and every other vitamin c serum I’ve tried in the last (including a $160 one) have either irritated my skin or caused me to break out. This one has been great! It absorbs quickly, leaves no shiny or sticky finish, has no smell and hasn’t irritated my skin at all. Will definitely repurchase.
