On a consistence it is transparent liquid, such slippery water, flavorless. I apply serum on moist skin 2 times a day, on the face (under eyes too), on the neck and on décolleté. 5 drops are enough for me. Stickiness disappears in a minute, and skin remains dry as though I put nothing.
I have seen result somewhere in a month. In general it is difficult to see result when constantly you see yourself in a mirror :-) But as that I have paid attention that wrinkles of "ring" on a neck became hardly noticeable!
