For about six years, the skin on my forehead has had two noticeably darker patches of skin on it. As far as I can tell, the skin on these patches is thinner, as occasionally the darker patches wear away again when I wash my face and bleed. I don't know what caused it, maybe I was washing my face too rigorously. I try to moisturise that area and not wash it too rigorously with harsh scrubs or not wash it at all if it's not greasy/spotty. But the skin never seems to repair. Any ideas of how I can fix this? Is there a product that can encourage skin healing /growth or uniform my skin colour on my forehead?
