Fab product

5 stars out of a maximum of 5

On my second bottle now, I was tempted to upgrade to Retinal 6 but for the time being I think the 3 is still effective. Not harsh and still get glowy results and my skin feels much smoother than it was at the beginning of the year. I will definitely stick to this line and try the 6 in time. Love that there is always a discount so feel like I’m getting a great deal.

I'm new to vitamin A and this is perfect for beginners. I've just started to use it and I can feel / see the effect cleaner, smoother and brighter - without any irritation!

Great first retinal

5 stars out of a maximum of 5

This is the first retinal product I've used and I'm so glad I decided to try it. It sinks into the skin very quickly and my face and neck feel beautifully soft the next day. Will definitely repurchase.

Great retinal

5 stars out of a maximum of 5

I have used this for years, I was using 10, but after anillness my skin became sensitive to everything. After a period of minimal skin care (barrier remain balms only) I am starting back down the lower end. I have nerve had a reaction to Medik8 retinal of any strength, and I think its a great price

Lovely

I am a gal who is very into skincare and do a lot of research before using products. This is the first retinal I’ve used after retinols and loved it so much! Only downside is how spenny it is!

My skin is prone to irritation to retinol. But never experienced any kind of sensitivity and irritation with this beauty. Love it to moon and back.
