Collagen Booster Intense Repair Serum

Reduce the appearance of fine lines, wrinkles and improve overall tone and texture.


Apart from water content, our skin consists primarily of collagen. Collagen provides the springy, plump and smooth appearance we associate with youth and health. When we reach our 30s, our bodies begin to produce less collagen year by year. The percentage of loss accelerates as we age, so we see less elasticity, more wrinkles, and sagging skin. At the same time, we can also experience damage to collagen due to sun, diet, pollution, and anything that causes inflammation.

Size: 1 fl oz

Who It’s For

How It Works

This lightweight serum unlocks the three keys to maximizing collagen levels – stimulate, condition and protect. Collagen Booster Intense Repair Serum promotes maximum collagen synthesis using hydrolyzed collagen, peptides, centella asiatica and stabilized vitamin C.

Hyaluronic acid and DMAE condition and strengthen skin’s collagen, while powerful antioxidants like resveratrol, phloretin, alpha lipoic acid, and green tea protect skin from damage and collagen loss due to stress, inflammation, and environmental factors.

Keep collagen levels at their best and see your most beautiful skin!

Collagen Booster.

Love it! Been using it for a couple of years. Use it every night.


I have been using this together with all the vit C and DMAE. Someone said my skin has gotten much better!


I love this product! Other collagen products have made me breakout in the past but I havent had any problems with this or any kate ryan product. In just a few weeks I've seen a small scar already start to fill in. Cant wait to keep using.


I love this collagen booster product, and using it with DMAE serum causes my wrinkly skin to be smoother! Definitely worth every penny!


I've been using KateRyan skincare about 5 months, and my skin feels wonderful, less lines visible on the forehead and around the eyes. I had collagen injections about 4 years ago and my face and skin felt fuller and smoother, but that only lasted about 3 years. Since being introduced to the vitamin c serum and the collagen booster serum, my skin and face are almost back to the fullness and smoothness I experienced with the injections, which by the way are painful and expensive. I'm very happy with all the products, DMAE serum, retinol serum and even the cleanser, which I wasn't crazy about at first, but have definitely changed my mind! Keep doing what you're doing, I'm a fan!
