Finn Cosmeceuticals White Advanced Brightening Cream - For Elbows, Knees and Knuckles. Lightens, Softens, Smooths & Retexturizes, 50g

I have almost black coloured elbows and brown coloured knees. I have been using it since a week now and I think the product is working. However the process is quite slow. I see only a slight difference in a week when I have not been consistently using. It is advised to be used 3 times a day for better results.One more thing that it does lighten ups the skin, however after and while using it, you need to take a good care of elbows and knees to not turn dark again.
