I love this brand anyways and this product is not the exception.......I apply it at night and my skin feels so smooth and looks very hydrated. I need more time and product to see if it really brightens and tones skin.

Thai is great. Makes my skin feel so smooth without greasiness. I will not be purchasing it due to the price.

Ove!

I am in my 40's and am noticing fine lines and wrinkles but don't want to spend a fortune on BOtox and fillers. So I'd rather use creams and oils to Moisture my skin. So far, So good!

Not for me

I wanted to like this based on the description and ingredients. It seemed to go on nicely and was not irritating at first. After two days I noticed more acne from my sensitive skin and stopped applying.

Pure Magic for my face!

I've just started noticing aging signs on my face and this was terrific! It smoothed away some of the fine lines and left my skin feeling supple and smooth all day.
