I'm 31, so I would say that the properties of the serum in full will not be able to appreciate. General impression: a good pack, I came with the normal dosing (because of economical consumption), even the label, glass bottle, 60 mL of the product, compared with 30 conventional serums. Consistency helium substance transparent light beige color, which is instantly absorbed. But unfortunately, I liked it a lot less than their hydrating serum (that all just a fairy tale!), No complaints, but the effect can not see something ... She gave her mother, so she appreciated! She loved it! Concludes - work well on the skin of age. Therefore, all the same five, because there is nothing negative I experienced during use. I hope that helped you with a choice.
