Light , a little sticky but absorbs  quickly.It is suitable for my sensitive skin 

This is a nice serum for those who have oily skin.

The quality/price ratio is good, moisturizing without greasing, but looking at the formula, I prefer the MMHC2 from NIOD.

I use this serum as my last-step clean care routine as moisturizer ,I like the texture of it as it is just slightly thicker than water, but i personally do not like the smell of this serum.

I've been using it for almost six months and just can't see any results. It's not hydrating at all, very sticky and greasy, the feeling when I use it is unpleasant, if it's warm outside (=15C and higher), the greasy feeling stays for the whole day. Can't see any significant improvement of my skin condition after half a year daily use, cheaper vitamin c serums do the same job even better.   I have sensitive, combined skin.
