Have not used it long enough to see the effect
It has niacinamide in it so it might cause purging. Would recommend doing a patch test. So far, it haven't cause me to have any breakout.

It really makes a difference!
At first I was hesitant to try this product as it is quite expensive (for me) but my friend convinced me to try it as it works wonder ok her. Initially, I did not see anything different happening on my skin but as soon as I stopped using it, my skin started looking dull and without glow. I went back to using this and it gave back what lacking on my skin. It is a really good product. Oh, and even thiugh this product is a little pricier than most essences I’ve tried, I have to say it lasts a long time because it contains a lot of products inside. :)

awesome
this is a great essence! it's on the liquidty side, but very moisturizing. almost done with this!

can't pinpoint exactly what it does but loving my skin so far
Used about 20mL of the product already... I couldn't pinpoint exactly what it does for my skin yet. Maybe it's one of those products that you only see the difference it makes once you stop using it, lol! However I plan to continue using this as a FTE in my regimen. No harm done to my skin, it's affordable, unscented which I like and safe, ingredients -wise. No plans of switching whatsoever. :-)

yess
this product enhanced the appearance of my skin and increased my skins moisture and elasticity! also highly moisturizing! love it
