The best retinal by far

5 stars out of a maximum of 5

Over time I've worked my way up to ret6, Without any complications I can't tell you how good it feels to finally have something that actually works

Amazing range

4 stars out of a maximum of 5

Just finished my bottle of 3, now onto 6. I wake up every morning to soft, bump free skin when using this in combination w moisturiser. The only reason not 5 stars is I expected a bigger difference between 3 and 6, still great just not much difference on my skin

Well worth the cost

5 stars out of a maximum of 5

I love this product. It’s expensive and gets more expensive as you move through the levels but I have to say it’s worth it. It’s nice oily, it doesn’t cause flaking and I could see a difference after a month of using.

A favourite and a staple

5 stars out of a maximum of 5

With my skin being very sensitive my skin doesn't tend to tolerate retinol type products very well but i'm absolutely fine with this. I use it 2-3 times a week generally and don't get the same irritation i've had in the past from using similar products. I don't wake up with my skin feeling dry/tight either and I really like the smell and texture

The best retinal ever!

5 stars out of a maximum of 5

This is by far the best retinal I have ever used. I have used quite a few retinols but nothing compares to retinal, especially this one from Medik8. The first time trying it a fine line on my forehead had reduced overnight! I love that its available in different strengths so your skin is always improving. 10/10 would definitely recommend to anyone!
