Rated 1 out of 5 by from Unfortunately not for me I use Differin - Vit A - and using this in the morning and Differin in the evening for the last two and a bit weeks completely wrecked my skin leaving it sore, dry and breaking out in spots. Even now a week on from not using the Vit C it's still a mess. I am very precious about my skin as I have had a lot of acne issues and now I am having to try and sort out the mess. I love your other products but this isn't good for my skin.

Rated 5 out of 5 by from Favourite skincare staple I've been using this for a year now and see a significant improvement particularly at this time of the year when I'm prone to rosacea. My skin is calmer and it feels like a luxurious treat every day

Rated 5 out of 5 by from Great products that work! I love the medik8 range. Started using them around 3-4 months ago, with the crystal retinol and advance night restore. . then added the c-tetra lux and hydra b intense. Definite results in the appearance of my skin hydration and smoothness. I’ve used retinol and hyaluronic acid previously but these gave me a bit more added ingredients. I’ve recently ordered surface radiance cleanser and liquid peptide samples. So all good so far and definitely would recommend trying!
