Gentlier than trentinoin, but just as effective

5 stars out of a maximum of 5

I had switched over to Medik8 Crystal Retinal 6 from tretinoin because tretinoin was just so harsh on my skin. I've found that this is as effective without all the side effects --redness, dry skin, or peeling. I definitely recommend this for those who want the benefits of tretinoin without all the side effects.

Latest technology in skincare

5 stars out of a maximum of 5

I wanted to upgrade from my 1% retinol and after some research, I found out that Retinal is actually the best form of vitamin A right now to help with signs of ageing, hyperpigmentation and enlarged pores. I started in the Medik8 0.6% right away as I’m already used to retinol - if you’re starting just now with it go for the 0.3%. I had no irritation at all (I use a specific retinal product for around the eyes), I’ve been using every night, sometimes followed by a night moisturiser. My skin is glowing and imperfections such as hyperpigmentation are definitely improving. I truly recommend this product to anyone wanting to upgrade their nighttime skincare routine.

A retinoid innovation

5 stars out of a maximum of 5

Lovely texture, sinks in very well, and a nice smell (unusual for a retinoid!). I love that it's the more advanced form of retinal and trust that this will give better results over time. I use retinoids more as a preventative as I don't have many fine lines yet, but I feel confident that this will keep my skin youthful for longer. I actually use this every night and have zero negative side effects, despite the fact my skin is naturally dry - impressive.

Helped my acne

5 stars out of a maximum of 5

I have almost finished the tube now and purchased the crystal retinal 10 to progress to after this. Found I got a little itchy when over-eager at the beginning but as you should with retinol just ease yourself in. Use every evening now and have found it has improved the overall texture of my skin and also reduced breakouts. Now I have been using such a long time (4 months) have really noticed under skin spots/lumps all but gone now! Fairly pricey but happy with results and has lasted a long time as I’m not stingy with it either!

Great product poor packaging

4 stars out of a maximum of 5

The biggest improvement in my skin after a month, my pores were significantly smaller and less noticeable. Also, my skin texture actually improved although I already had a nice texture. I really like this product. My only issue is at his price, the pump should work till the product runs out. Poor packaging for the price.

Fantastic product

5 stars out of a maximum of 5

I have been using it for 3 weeks and have already seen a big difference in the texture and brightness of my skin! I’ve had many compliments and questions about what I’ve been doing. Using currently 3 times a week! Would definitely recommend it.

The best night-time serum

5 stars out of a maximum of 5

This serum/cream retinal has given me none of the skin irritation/dryness I typically experience with retinol. I've slowly worked up to two pumps and my skin feels calm, plump and texture is much more smooth. With the few spots that I have, they've already diminished. It absorbs very quickly into the skin and has a faint scent that doesn't linger too long. With absolutely no irritation to my skin, ease of application and the fact that it doesn't come in a clumsy pipette glass bottle, I will be repurchasing this until the end of time!
