Rated 5 out of 5 by from Absolute Holy Grail for Plump, Youthful Skin! [This review was collected as part of a promotion.] ​I have tried countless peptide serums over the years, but this is hands-down in a league of its own. If you are looking for a product that delivers real, visible results without irritating your skin, this is it. ​This leaves my skin feeling instantly hydrated. It completely gets rid of that tight, dry feeling for me. My skin looks noticeably firmer and smoother. ​It is definitely an investment piece in a skincare routine, but a little goes a long way, and the results speak for themselves. My complexion looks radiant, plump, and healthy. I will absolutely be repurchasing!

Rated 4 out of 5 by from Good for dry skin [This review was collected as part of a promotion.] I use full Medik8 regime and last time I switched C-tetra advanced for C- Tetra Lux as my skin had been become too dry. With moisture is fine now, but my pores becomes more enlarged, so I'm going to return to 20% vitamin serum. This product I would recommend for everyone who is struggling with skin dryness . It is as well a problem with RM scam delivery. It would be great to have an option of licker delivery. Now it's very hot and this product stayed unnecessary in RM for 2 more days.

Rated 5 out of 5 by from Vit C day cream is a dream in a jar! [This review was collected as part of a promotion.] I have tried moving away to Trinny London products but realised packaging is noghinjg compared to quality of product. If your 40 plus and especially 50 plus. It's such a luxury cream and I do get so many compliments about my glowing skin since moving back to medik8 . It's super rich but non greasy my skin just absorbs it so quickly. I look forward to using it every day.

Rated 4 out of 5 by from This serum has a watery, [This review was collected as part of a promotion.] This serum has a watery, but still oily, texture. It does run well in the face and neck. As I am over 50 I really need a higher vitamin C concentration but started with this because I have sensitive skin. I make sure to apply it once my skin has dried from clearing and before moisturizer.
