I purchased this in late December and my bottle is nearly finished. So little irritation that the product actually feels soothing to my skin. My face glows the morning after using this and it's definitely softened my skin. I'll be trying 0.5% retinol next but will likely repurchase this too to use on days I don't use the stronger serum. I'm so impressed.

Amazing product. Skin looked younger just after few days of using it. I love all no ordinary products!

Have been using this since November. If I want to be honest, there is no real change that I can see on my skin. Unfortunately, it does clog my pores on my cheeks. I noticed that whenever I apply this my pores look bigger than when I am not using it at all.

I’m using the bottle about 1 year and no wrinkles and irritation I’m very glad that this product and price. I will buy again and again.

Age: 46. Skin type: combination/ sensitive. Major concerns: first signs of ageing, fine lines, brown spots. I've been using this product for a month at night along with Buffet” + Copper Peptides 1% and Marine Hyaluronics. Pros: Doesn't irritate my skin, skin feels soft and "renewed" in the morning, noticing that a small bump/ enlarged pore on my forehead is getting smaller since I began using this product. Cons:Packaging: I'm a bit concerned that every time I use it, some air may get inside the bottle and break down the retinol/ I'd prefer the TO used pump dispensers rather than eyedroppers Overall: love it and will buy again/ would recommend to a friend.
