First Retinal

This is my first retinal and my sensitive skin has responded really well. It’s got a lovely texture that absorbs quickly into your skin, and the pump delivers just the right amount of product.

Really enjoying!

Bought the eye cream to go with it and loving them both so far! my face looks a lot more youthful and glowy. You can tell it's really working but still feels quite gentle at the same time! Will definitely repurchase although not sure if my skin is ready for CR6 yet!

Excellent product

I got this in a beauty gift box.  It’s a gentle introduction and apart from a tiny breakout initially all seems good.  A little goes a long way so £/application seems very reasonable. Once I’ve used this up I will move up a strength as it seems to do the trick and my skin is happy.

The best retinol and I love the fact that you can move up strengths once your skin has adapted to it!

Love

This was a repurchase, really happy with this product. I don’t get any sensitivity from this and it seems to be effective. My skin always looks especially good the morning after using.
