Retin-C Treatment Complex


Put the ultimate Super Nutrient Complex, 7% Vitamin C (STAY C) and 2.5% Rovisome (less abrasive, more effective form of Retinol) to work for you! Vitamin C has been proven to increase Retinol’s efficacy while making it that much more stable. STAY C, a potent antioxidant not only provides maximum radiance but helps the skin receive all the benefits of Retinol.
Retinols work by promoting skin cell turnover, allowing for new cell growth. The breakdown of collagen is reduced and skin is thicker at the deepest layer where fine lines and wrinkles begin. Research has demonstrated the two together increase the benefit of each. Retinol and Vitamin C together allow for the fight against free radicals, while protecting Retinol from oxidization as it penetrates deeper into the skin allowing maximum anti-aging benefits!

    Fantastic night serum! I was given this as a sample and loved it. It smells great, goes on easily so you don’t need much, and sinks in quickly so you don’t have to wait too long before applying night cream. My skin definitely looked firmer and brighter in the morning.

    I had a generous sample of this and used it on clean micro needled skin twice a week. It is quickly absorbed with virtually no scent. The following morning my skin is visibly brighter and clearer. I will be purchasing the full size when it comes back in stock.

    I really like Kat Burki’s products in general so thought I’d give this new treatment complex a try. I was a bit worried as have had major skin irritation from retinol products, but the Retin-C complex is really gentle – I have had no irritation and my skin texture has improved: smoother, brighter.

    I received a sample size of this in the beauty edit. I really like it. Great serum. I love all the Kat Burki products I’ve tried so far. I am looking forward to trying some more new products from the range.

    I haven’t used any products from the Kat Burki brand before so when I got this product in a GWP goody bag I couldn’t wait to try it out. I was wary of it being too strong for my skin as I haven’t used this type of product before but it wasn’t at all. I found it easy to apply, it absorbed into my skin easily and my skin felt really smooth after I applied the product. I really thought that it improved the brightness of my skin after a few uses as well. I do think the price is high so it is a considered purchase but I do like it.

    I have tried a decent sample size of this serum and since a little goes a very long way I was able to have about 2 weeks worth of usage with the sample. I really like the lightweight runny texture and it gets absorbed into the skin very fast, allowing faster cream application afterwards. It is very gentle too as opposed to a lot of similar products on the market that can be quite irritating. Effect is very subtle but noticeable, I got overal brightening and smoother skin. Maybe you’ll get much better results if you are new to vitamin c serums…
