I was sceptical after reading the bottle, but it really does work. Fine lines vanish.

Great Product
Purchased

My skin is dehydrated at the moment and it's starting to show some lines. This Concentrate is helping me moisturise my skin very efficiently. I couldn't say that it removed my lines (yet!), but it drastically improve the elasticity and texture of my skin. It looks better and fuller.

Couldn't tell a difference in lines

I'm 31 and starting to get some smile lines around my eyes. I was happy to get this sample and I used it every night until it ran out. It felt soothing and nice around my eyes, but I didn't really notice a difference in the appearance of lines. It did feel nice and warm going on though, so I'm sure it was doing something -- maybe preventative for further development of line, but I couldn't really tell. Maybe if I'd used it longer.

Worked wonders!

Although the directions indicate not to apply around area, I read them a little too late and wound up doing just that. I did notice that after just 2-3 days the difference in the fine lines I get underneath my eyes were less noticeable.

Loves this!

I am relatively new to wrinkle products, but I used the entire tube and went ahead and bought an actual bottle. I use this morning and night and it makes my skin look smoother and feel softer!

Great really works
Sampled

I sampled this and it was awesome. Goes on light, immediately makes your skin look more toned. It did make my eyes burn a little when I layered too much one once, but if you use a thin layer it feels good.
After several days I felt like my fine lines really disappeared. I like that this is a retin-a free product that actually works. Will likely be buying this soon.
