As this was only a sample, I did not get the benefit of seeing the result over a long period of time. What I can tell you, is that the serum though velvety, was thick and I could just imagine how potent it is. It did have a faint sweet fragrance and had a cooling sensation when applied.
Benefits include: oil-free, prevention of visible and signs of ageing, fights dryness, dullness and loss of radiance. The bottle is quite pricey in the market, so for me maybe when ageing signs become more prominent I might invest.
