Collagen Booster Intense Repair Serum

Return to Previous Page


What It Does:

● Reduces lines and wrinkles
● Firms and restores lost volume and elasticity
● Minimizes scarring and stretch marks
● Helps to heal acne and lessen the appearance of enlarged pores
● Smoothes uneven tone and texture
● Repairs and protects skin from environmental damage

Who It’s For:

All skin types wishing to maintain and restore collagen to the skin for a firmer, smoother, more youthfully healthy complexion at every age.

How It Works:

Apart from water content, the skin consists primarily of collagen. Collagen gives our skin the springy, plump, strong appearance that we associate with youth and health. However, once we reach our 30s, our bodies begin to produce less collagen year by year and the percentage of this loss speeds up as we age so we see less elasticity, more wrinkles, and sagging skin. At the same time that chronological aging produces collagen loss, we can also experience damage to collagen due to sun, diet, pollution, and inflammatory conditions like acne.

What’s the best way to keep collagen levels at their best so you see your most beautiful skin? Stimulate, condition, and protect. The Collagen Booster does all three. This lightweight 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, and powerful antioxidants like resveratrol, phloretin, alpha lipoic acid, and green tea protect skin from damage due to stress, inflammation, and environmental factors.

    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!

    Love this product! My skin feels & looks plumper the next morning. I love that it treats & helps to prevent further skin damage. I have hypersensitive skin with Rosacea & have not had any reactions. So thankful to have found KRS!!!

    I am really loving this product. It took 4-6 weeks for me to notice improvement, but now I cannot live without it. I use it at night since it can cause makeup to pill. You will not be disappointed with this product.

    Love KR Collagen Booster, it adds moisture to my skin, and seems to help my other products perform better. Love the KR collection.

    I am so happy at the end of the day when I get to massage this into my face — it just feels so good! The other day a casual friend told me that I was the only person she knew who gets significantly better-looking as time goes by… thanks for helping out with that, Kate Ryan 🙂

    The Kate Ryan products are top notch. I wish I could buy them all. The collagen booster is a must have though. I’m pleased KR is now carrying a daily moisturizer which I will get.

    I love it! I use it along with the KRS nighttime vitamin c serum just before going to bed and my skin has never looked better. Some of my acne scars have disappeared and my overall skin seems to be more elastic. I’m glad I found this company!

    First, let me say that Kate Ryan Skincare is a gem of a company! The customer service is hands down the best I have ever experienced. I had a question about serum usage and it was answered personally and in-depth within 2 days! And the best part… Erica couldn’t respond to my email right away, but she sent me a personal email letting me know she had received it and would respond the next day.
    I love the Collagen Booster Intense Repair Serum. It makes my skin feel a little bit tighter and I’ve seen an improvement to a very old scar on my face. I’ve also seen an improvement in the fine lines on my forehead. I like knowing that I’m preventing future damage and already fighting the inevitable fine lines around my eyes and mouth. The biggest compliment, however, came from my husband who told me my skin was looking healthier (after 2 weeks of use of multiple Kate Ryan skincare products)!

    I am beyond happy with all of the products I have purchased from this line. You are provided with a ‘recipe’ which makes it easy…and the recipe works! My skin looks more dewy and youthful, and refreshed.

    I have been using the Ultimate Hydration Collection along with the Vitamin C Collection for about a month. Yesterday my daughter looked at me from across the kitchen table and asked me if I was using something different on my face because my skin looked so smooth. Yes!!!
