This is a very good product, the lactic acid is very hydrating. I somehow feel that the retinol content is bit less than the claimed 1% after trying some other brands.

This is the only serum which keeps all its promises! High efficacy, excellent tolerability. Before buy the big size I purchased the little format because I was afraid about tolerability. But without any irritations in just 2 weeks Iachieved excellent results: less wrinkles, firmer skin, less discoloration! Inlove it! 😘🥰😍

In the last 20 years I've tried to use retinol from various brand, but every time some irritations have occurred. So I was very scepter about this serum and I've bought the small size because I was afraid. But… surprise! I have gradually introduced it in my night routine and no irritations have occurred! And when I wake up my skin looks refreshed and pumpled! Chapeau, Shni Darden!

I have sensitive skin and have been reacting badly to retinol, but this went on seamlessly and seems to be very hydrating, too. As I continue using it I can see some real effects. I would definitely recommend 

I loved this immediately. I had heard about this in a video where it was presented as retinol that has no side effects. I have sensitive skin and retinol does not always work without redness, and reactions. This worked seamlessly. It promises rapid, youth-boosting results without side-effects. Also it promises to hide pores and deeply hydrate and I feel that it does what it promises, really! 

I got this in the 2021 advent calendar and then purchased a full-size version. I am in love with this retinol. Is it pricey? Yes. Is it worth it? yes! This is the only retinol serum I have used where I see a visible change in skin texture and complexion changes. Little goes a long way, so the bottle last for a very long time. It does not irritate my skin at all.

I have sensitive skin and this retinol doesn't irritate it at all. It seems quite potent.

This retinol is amazing. Super gentle and effective and makes my complexion look plump and glowy. A very good retinol product.

I have hormonal acne along jawline and while this helped prevent my monthly large spots. In its place I developed we pustule acne all over my face, which was worse. Because their is lactic acid (aha) and retinol it was too much for my skin. It’s odd this product combined the two when everywhere you look it recommends not to use on the same evening. I don’t recommend this. Medik8 is 100 times better if looking for a good retinol for sensitive skin.

Retinol is only something I introduced into my routine around 6 months ago. Prior to this, I was using a retinol serum with a lower strength but I was able to swap to this every evening without any irritation whatsoever. Since I have been using this ( around a month ) my skin is looking a lot brighter ( this is also thanks to the lactic acid in the formula!) and I've noticed the fine lines on my forehead are a lot less noticeable. If you are looking for a new retinol serum I would definitely recommend giving this one a go!
