Seems ok
I have been using this consistently since i received it in the egg edit. It absorbs easily and smells lovely. My skin feels soft and it leaves a lovely glow. I haven’t noticed a difference in pigmentation however i will purchase again and hope for the best!

Perfect vitamin C
One of the best vitamin C out there. Is on the pricy side but is worth the money. I use every morning before moisturiser and SPF
