Hope for skin of colour

I purchased the 30ml Advanced Hyper***mention treatment due to the very attractive ingredients which targets stubborn ***mentation. There are very few products out there with a combination of all powerful ingredients in one package. I was also impressed with the packaging, the very best I've come across for active ingredients.Just disappointed that I had to discard of the product whilst halfway through using it because it turned from a white to a dark brown colour. So I didn't get to use this product long enough to experience the effects of it and it's quite pricey to be using just half and discarding the rest. Not sure if this is due to oxidation but hopefully the business can work on resolving that issue. Would love to see this business grow and improve on their products as it addresses some real skin issues that we women have to deal with. Just a tip to those who would like to try this produt, rather start with the 15ml.
