Product Description

Medik8 has long been considered royalty of the retinal world, and its supercharged Crystal Retinal 20 (30ml) takes the brand's reign to new, skin-smoothing heights...

This silky night serum for retinal regulars contains the strongest concentration of vitamin A to come out of the Crystal collection to date (that's a potent 2.0% retinaldehyde for all the skingredient buffs out there). Expect a complexion that appears smoother, brighter and oh-so-supple. That's not all though: the addition of hyaluronic acid, vitamin E and glycerin provides a soothing and hydrating pick-me-up to ensure that this super serum is gentle to even sensitive skin types.

I think other people notice the difference more than I do. But, I do feel that my skin becomes a bit grainy after use, probably because the skin becomes sensitive?

My favorite retinal

5 stars out of a maximum of 5

I started using this retinal at a dose of 3 and have increased it to 20 over three years. I use it year-round at night under my moisturizer. I'm very happy with the results. I am 50 years old.

My go-to retinol

5 stars out of a maximum of 5

I buy it for autumn/winter season. My skin is accostumated to this strength already. I use it at night and I like the texture: lightweight and easy to absorb. I like my skin after using it: smooth and hydrated.

Disappointing results and significant texture incompatibility

3 stars out of a maximum of 5

I have used the Medik8 Crystal Retinal 20 several times, pairing it with the matching eye cream. Unfortunately, my experience has been underwhelming. Every time I apply a facial oil over the retinal, it causes 'pilling', creating soft, lumpy clumps all over my face. This suggests that the formula does not absorb well or reacts poorly with oil-based products. Plus, despite consistent use at this high strength, I haven't noticed any significant reduction in wrinkles, improvement in skin tone, or fading of my sunspots. For a product at this level, I expected much better performance and absorption

Best retinal product

5 stars out of a maximum of 5

I have been using Crystal Retinal for years. I’ve tried all strenghts and I find this one perfect for my mature skin. No irritation (unlike tretinoin), it does not trigger my perioral dermatitis and it's really hydrating. My skin loves it and it will remain in my routine for ever. I am loving all Medik8 products.

Great cream

5 stars out of a maximum of 5

I bought this cream with all the discounts for 94 euros. I really like this brand. I've already had 2 creams: Retinal 3 and 6. The skin just glows! I decided to buy for next season with more concentration.

Powerful

5 stars out of a maximum of 5

Worked my way up to 20. I found the transition from 3-10 easy with no problems, used 20 nightly at 1st as I was feeling cocky but my skin soon broke out & my barrier was damaged. Back to every other night & working good. Only negative is that it stains my pillows & doesn't layer as well as strengths 3 & 10.

Maximum Strength, Clinical Level Results

2 stars out of a maximum of 5

Medik8 Crystal Retinal 20 is one of the strongest over-the-counter retinal products available and delivers very fast visible changes in texture, clarity and fine lines. It is highly effective but also very unforgiving: dryness, peeling and barrier stress are common if your skin is not fully adapted. Best used only by experienced retinoid users with a slow, controlled build up. Texture is elegant and absorbs well, but the strength puts it firmly in the “advanced treatment” category, not daily cosmetic skincare. Short verdict: extremely effective, but only for skin that already knows what it’s doing.
