I can not remember when I purchased this serum, but definitely a long time ago. And I used only one third of it. It really lasts incredibly long. I use it 3 times a week before sleep (2-3 drops) and since it is oily (squalane), I think it is very appropriate for winter time. It makes my skin very soft and younger. For sure great value for money.

I have used the retinol for about a month and can see that my skin does feel a bit smoother and cleaner. I have breakouts from time to time, and I feel that this retinol helps with them too. The formula is very rich/oily so does not dry out the skin as some other products might do. I wouldn't say it gives you a massive skin change, but as an everyday product is quite okay.

This one did nothing for me and I hate how greasy it is. Also didn’t see any changes on my face while using it regularly. 

Love this. I’ve used a couple of their retro oil products and have built my way up to 2%. Nothing bad to say about this product and it’s definitely improved my skin. And for the price - BUY IT NOW :)

I switched from 1% to this 2% retinol product.All looks well. No irritation.
