Great retinol

I have been working my way up through the strengths. I would definitely recommend Medik8’s retinols. I have had compliments on my skin since using them.

So far so good

4 stars out of a maximum of 5

Only used 3 times as only use retinal once a week but does have dead skin cells on the surface after sleeping . Use along side other medik8 products to get full benefits

A good starting point for retinol

5 stars out of a maximum of 5

My skin did not experience any sensitivity to this product. Used every other day and then built up to everyday, before bed. Pleasant scent and left my skin looking glowy and feeling smooth. Always use spf as can increase sun sensitivity.

worth it

5 stars out of a maximum of 5

been getting into retinol and this was the second retinol i’ve tried, it’s not irritating on the skin and the packaging keeps it mess free and it’s hygienic! it’s pricey but it’s made a noticeable difference in my skin texture and appearance

I have just started retinal and moved straight on to this one, I’ve only just found out I shouldn’t of done that but as it may cause irritation but this really hasn’t, in the small time I’ve been using this I’ve really started noticing a difference

Great first time retinal serum

5 stars out of a maximum of 5

This is my first time using a Medik8 retinal serum. Within a couple of weeks I could see a difference, my skin looked much clearer and had less redness.
