Mum likes it so far

Bought as a gift for mum and she likes it so far. Thinking of getting one for myself too hoping it would calm my acne down.

Swear by this retinol!

The best retinol product I’ve used, I use it nightly

Best in every aspect

I always wanted to actually stick with using retinoids, however, I am very critical of textures and user experience, and simply no product did it for me - I couldn't bear to use them long enough to actually see improvements, until I finally gave in to the rave this product has and bought it. Bestest decision ever, truly. Texture is divine, non-greasy, effective. Already repurchased!

Gentle on the skin

I love this medik8 product. I use liquid peptides in the morning and this product for the night. I used it exactly how it was recommended and my skin in the morning looks fresh and plumped. Definitely recommend!

Visible effect

First product from the brand - there was a visible difference on the first use in the morning. Didn’t cause any irritation, and absorbs well as the first layer. As an added bonus, the packaging is quite effective and hygienic. I look forward to trying other products from the brand.

Love, will repurchase

Obviously the benefits of a retinol/retinal are long term, but my looks incredible the morning after after using. I have dry skin but I don’t feel like this is drying or irritating, though I have only been using once a week and use a lot of hydrating products in between. Will absolutely repurchase, possibly the retinal 6 depending how I’m going when I get toward the end

Early Days

It’s still early days but I was looking for a higher strength retinol and this comes highly recommended. Im using it as directed and building up the tolerance, some localised break outs but that’s to be expected with a retinol. A few weeks in and I’m waking up and my skin is super soft!

Love it!

Have been using it for the past 3,5 weeks now. My skin looks much clearer and no sign of any redness and skin discoloration.
