I’ve purchased this serum about 6 times? Maybe more who knows It’s not too agressive but still does the job and I wake up with a glow. I will say it took me some time to realize it works best for me if I use it every 5 days - I have very sensitive skin

Didn't see any improvements and I just hate the packaging - you can't get all the product out and must cut the tube open to use this thing up. Shouldn't happen at this price point...

Been useing this for over 6 months and I do see slight difference. With retinol you need patience and since this one is not as strong as the other ones from this line it does not have a huge effect. I already repurchased it and plan to start with number 3 after I finish it

I buy it for myself, I buy it for everyone. The best in the market. I have sensitive skin and it didn't cause any issues for me. The weaker version wouldn't be enough for me so unless one has rosacea, this version is pretty good. One tube is enough to see improvement in fine lines and texture and can't wait to see better results with the second tube. 

it's a bit an expensive product, but it has been working great for me! I use it once very 3 days to avoid irritation
