Great product!

It’s a great product and I see visible quality changes on the skin while I use it. For some reason, closer to the end of the bottle content, the serum gets a bit yellow, probably this is the impact of oxygen.

I have summarised my experience in the review.

The texture of the serum is very smooth, but it has not really been effective in reducing puffiness under my eyebrows.
