Covers all areas

My go to night cream (well every second day). Cover the retinol, exfoliation etc. love it. Been using for about 6 months. This is my second tube. Love it!

Hello Retinol

I had never used a retinol before, but wanted to give one a go. Mind you, one of the reasons I hadn’t used one is because I was scared for some reason. I think all the stories of people over using it and “burning their faces off” scared me off. After doing some research I settled on Cosmedix Define and I am so happy I did. My skin has handled it well and I haven’t had any trouble with it.

Cannot go without this product - highly recommended!

I have been using the Cosmedix Define for almost three weeks now and have noticed changes in my skin. My skins texture has become a lot smoother, old scars have begun fading away and my complexion has become a whole lot brighter. I use this product every second night and this product has now become a staple in my skincare routine.

The only retinol I would use

I have combination skin which is prone to breakouts. I first bought Cosmedix Define at the recommendation of my beautician prior to my wedding. I had tried a pharmaceutical retinoid in the past and it made my skin peel quite badly. I find Define is gentle enough that I can use it 3-4 times per week. I’ve now been using Define for about 2.5 years and have noticed the texture of my skin is better, I have less acne breakouts, my pigmentation has faded and overall my complexion is better.
