I am currently using this serum and loving it. It absorbs fast and can be used during the day and night. I saw visible results within a week of using it, in terms of the suppleness and brightness of my skin especially in the morning. In two weeks i noticed that my skin looked really good.
The texture is not sticky, it just glides on the skin and a little goes a long way. This was my first retinol use and it did not cause any pimples or reaction at all, period.
At some point i used this together with the olay retinol 24 at night and to my surprise they paired really well but i alternated the olay with a ceramide cream.
This is perfect for first time retinol use, i think its formulation is such that it does not irritate. The bottle is written highest concentration - great stuff.
It comes only in a 30 ml and it does last. I use it very often but not every single day. I've had it for 3 months now.
It is pricey though but worth it.
Worth buying!!
I love it
