I have both the versions of this serum - this pink and the blue one with cica.

I like them both - both contain complex of 5 hyaluronic acids and is therefore the best hyaluronic acid serum that I haveever used. I have already purchased several bottles of those so it is safe to say this is now an integral part of my skincare routine.

This pink I appreciated especially in winter when my skin was lacking on vitamins. The blue on, on contrary, is more clming and helped my skin in the summer after the sun exposion.
