This serum contains two notable anti-oxidants. Both are said to be very beneficial to the skin.
It is however, much more concentrated than other similar products that are on the market (though considerably cheaper). So you need to introduce this very slowly and carefully into your skincare routine.
I used too much during the first application and my skin stung so much that I had to wash it off within a few hours. I then experienced some redness and peeling the next day.
So I went back to it with caution. I started by mixing just one drop with another thick serum that I use. I have now increased this to 2 drops and do this no more than every 2-3 days. My skin is now coping with it well. I don't intend to go to daily use for some time.
This is an excellent product but needs to be used responsibly!
