Skin Brightening

How It Works

I have been using this serum for a year. But I have realised that nothing much different since the 1st time using. It was clear my black spot from acne but now it’s not really clear tho still has a slightly mark in my skin. Probably my skin get used to it.

Simply brilliant

I really like how this product is lightening imy pigmentation it hasn't got rid of it totally but in saying that I have only used it for a few weeks. Skin definitely feels brighter so I will persevere with the product and when I run out perhaps try another bottle.
