AMAZING!

Bought this with a discount code as my cheaper Retinol product had run out. This stuff is amazing! Since I am a regular retinol user, I didn't experience any sensitivity and have been using it about 3x a week as part of my evening routine. I am currently experiencing a little bit of a purging period, but nothing that I wouldn't happily work through for the next couple weeks. My skin overall looks brighter, smoother and fresher and I have a feeling it will just keep getting better after several months of use.

Very good

I’ve tried a few retinols over the time but this really does leave my skin soft & clear I’m only using 3 times a week at the moment I think that this is enough for my skin

Well what can I say this product is just THE best! After struggling with my skin I was recommended this by a friend... I had results pretty much overnight and they just keep getting better!

Very good

I bought this in April and had been consistently using it about 3 times a week. I used it after cleansing, and then I layered the Medika8 Advanced Night Restore after. I am quite happy with this product. It is effective without being too strong and causing any bad reactions, despite it being a retinal. Layering on a really good moisturiser after the retinal really helps, and there was no dryness or irritation. My skin felt smoother when I woke up in the morning, the texture is creamy, and the scent is like vanilla and quite subtle. I am almost done with the tube I got and had already purchased the retinal 6, ready for the upgrade.

Medik8 Christal Retinal3

This was suggested to me by a Cult Beauty Lovely Lady and I think the product itself is fabulous, really suited my skin without complication and helped to reduce uneven skin tone even on my rapidly ageing skin. The packaging is unfortunate. The pump at the end of the tube lasts about 5 times. It was suggested I squeeze the tube whilst pressing the pump top. Didn't work either. Solution; either waste the rest of the product still in the tube or cut the bottom of the tube and squeeze the remaining product into a CLEAN glass pot and just hope the product keeps its efficacy. So sad as the products really do what they say. Wanted to buy their SPF but note that has the same daft top. Also wanted to 'go up a notch' and try the Retinal 6 but think it would be the same problem. What's wrong with a simple tube you can squeeze then replace the top. Simple!

No difference yet...

I can't see any difference in my skin yet but I've been quickly able to move to applying this on a daily basis with no ill effects. The smell is lovely and it sinks in quickly. I have only just learned that this should be used on the eye area too with eye cream applied after it sinks in.

Brilliant

This is my first retinol but I am converted. No redness or flaking but visibly better skin - both in terms of pore size and fine lines/radiance.

Lovely product

I have been using this for about 4 weeks now and really like the product. I have also upgraded from The Inkey List and find I get no irritation or dryness at all. The only issue I have is with the pump which doesn’t always dispense the product. I will definitely repurchase.

Love it!

I 'upgraded' to this from the inky list retinol serum and will never look back. The texture was a bit weird at first, a lot thicker than I was used to at serum stage. However, I've had zero irritation, and my skin doesn't feel dry or tight on waking up, in fact it feels lovely and smooth. I've been using it for a few weeks and have already seen a difference in my pores. Love it.
