I was lucky enough to get a sample of ESPA Optimal Skin ProSerum and I am loving it.
It comes with a droplet and this makes it feel a little scientific but also as if your using something exclusive and luxurious.
I mix the oil with my moisturiser and don't feel dry until the next day.
This is saying alot since I suffer from dry skin.
It normally retails for £48.00 and after learning this I will be rationing my supply.
Have you tried it?
