Medik8 Crystal Retinal 20 - Age-Defying Retinal Night Serum - Improves Wrinkles & Skin Firmness- 0.2% Retinal Strength - 11x Faster than Retinol - For Highly Experienced Vitamin A Users - 30ml

I can't speak highly enough of Medik8's retinol range - it's kind enough for my sensitive skin, the cream formula minimises the risk of it degrading, and the different strengths mean you can adjust daily based on what your skin is doing. I've been using 6 & 10 for some time now, and dared to venture to 20. It's noticeably thicker than 10, and also makes your face shockingly yellow (this is a sign of good quality retinol, apparently), a little sticky on the pillow. But despite its strength, I've had no irritation, using once or twice a week, alternating with 10. I always us a peptide first (Medik8 or Vichy89), and if I notice any dry or tight patches, I revert to 6 for a few days. I've used retinol for so long I wouldn't have a skin 'transformation', but Im in no doubt that retinol has been keeping my skin texture in good nik, and this is by far one of the best I've used.

It cost more than I usually pay but thought I would give it a try. To be fair I haven't used it religiously or regularly. It didn't cause any rash or burning. I can't see myself purchasing it again, probably hype. I read that retinal content has to be very high to be effective and these creams are only available on prescription, used for burns victims etc.

I've only just started using this. Need more time for results I think it's helping though

This product has made no difference at all a waste of £77and this was highest retinol content wouldnt recommend

Excellent product quality and efficiency.
