My new essential

I only started retinol about 18 months ago, and this is the nicest texture product I have used. It has a mild scent and I find is fine to be applied direct to the skin. The strength 6 seems about right for me, having worked my way up from a 3. Can definitely notice smoother skin around my eyes

Love Medik8

Great retinol but make sure to build up with lower levels first. This is suitable for sensitive skin & nice to apply. Great results.

My new favourite retinol

So pleased I took the plunge and went for a higher strength retinol! This is such a GORGEOUS serum, doesn’t dry my face out or cause any redness or irritation. I’m early 30s so usage is age-preventing. And such a bonus that Cult has it on offer. Will absolutely be repurchasing!

Never got irritation from this, don’t even use a moisturiser with it. However hard to tell how much difference it has done just yet

My 4th Bottle

Amazing texture and I really see the difference in my skin after a month of using it. A little goes a long way and the formula is just gorgeous. Plus point is that it comes a pump!

After using the 3 I have stepped up to this. I was a bit nervous but my skin really suits it

Powerful serum

I was on retinal 3 to begin with and now have moved onto the 6. It’s been very pleasant. It delivers a powerful hydrating effect to help soften and smooth my skin, it looks more bright, refreshed and radiant. This one has a advanced complex and is powered by wonderful ingredients that works very faster than retinol to target the look of pigmentation, fine lines and wrinkles for a smooth, even complexion. It’s definitely a winner the serum is rich in antioxidants and really helps protect my skin.

Amazing!!

I have sensitive skin and aged 41, I found this product goes on beautifully and I am certainly starting to see improvements in my skin's texture. It has been a seemless experience having recently upgraded from level 3 of the same product line
