Gentle Powerhouse for Radiant Skin

Medik8 Crystal Retinal 3 is a game-changer! It’s gentle yet incredibly effective, making it perfect for beginners or those with sensitive skin. After just a few weeks, my skin looks smoother, brighter, and more even-toned. The 0.03% retinal works wonders without causing irritation or dryness. A must-have for anyone looking to elevate their skincare routine!

Second purchase

This is my second purchase of the retinal 3, beautiful formula and have to say it does what it says on the label! Will increase to the 6 after this is finished

Gentle formula

Love this serum. It’s more like a cream and isn’t greasy on the skin at all. I’ve not been a consistent retinol user before so started with the 3 but will level up to the 6. Great scent and a little goes a long way!

The only retinol I'll use!

The only retinol I've tried where I can see actual results with continued use and I'm thinking about moving up to the next strength. I don't have sensitive skin but never had any irritation and has massively improved my skin texture!

Helps to fight fine lines and wrinkles

With a moderate concentration of retinaldehyde, it promotes skin renewal and helps reduce signs of aging, such as fine lines and uneven texture.

Best retinol

Doesn’t make your skin sensitive, is the best out there. You see results consistently. I’m on my 4th tube

Excellent

No sensitivity despite never using retinol before. Can easily use every day or every other day to alternate with other serums. Made such a difference to my skin - small bumps gone, more even tone.

Excellent

I really like this product! Made my skin softer and reduced some pigmentation from past sun damage. I had a brownish spot under my eye from it which is now barely visible. But again, you need to protect it from future sun.
