Not for sensitive skin

My skin is really sensitive and unfortunately this was still too strong. The texture is really nice though.

Great product

I like this retinal. it has a nice creamy consistency and I do see results without irritation. Only downside for me is that is drys out my skin.

No irritation at all

I'm a long-time retinol user and so I did not experience any irritation when I switched from my Paulas Choice 1% retinol serum to this Medik8 product. I have combination skin with rosacea but my rosacea did not flair up at all after the use of this which proof that it is well formulated. I can highly recommend it to sensitive skin people.

Expensive but good

I have sensitive, combination skin with rosacea and this vitamin c serum did not irritate my skin. I bought it over 5 times and the bottle lasts 6 month. I would recommend to store it in the fridge during summer because one batch got oxidized during my Italy summer vacation but otherwise I would say it starts to oxidize from month 5 and so I think this is fine and still works. The consistancy is great for sealing in your hyaluronic acid. It does not peel off under makeup.

good but expensive

I did like it but if you continue with the crystal retinal series it gets very expensive over time, I use the Avene Retinal instead now

Night cream

Would recommend this product for plumpness and smoothing skin tone however use sparingly as can cause dryness and definitely follow directions as to how to introduce into night time regime

This is amazing for beginners

I always wanted to use a retinol serum which meets the needs of my sensitive skin and I’m so grateful I found it. This retinol is perfect for beginners and does not irritate or dry out the skin. It still works its wonders  but it takes a certain amount of time to see some results. Soon I’ll by the one with a higher concentration.

Very gentle

I have very sensitive and rosacea-prone skin and this caused no irritation. I used moisturizer around the eyes and mouth to protect the delicate area in case the serum would migrate there. The serum has a lovely texture and the smell is very nice.
