I started shaving 4 months ago and I noticed after shaving I would feel just irritation then it would go after 3 minutes. After weeks of shaving, I used the same disposable razor everyday never changed it for weeks on end. I had very grey grey grey skin and I started getting many spots in those areas. It was mostly my neck and sideburns where when shaven, I would have really grey skin. I've tried boot products, after-shave, dermatologist cream from doctor (dry skin), tried lemon, tried skin whitening product (fair&handsome) which my friend suggested but nothing seems to get rid of this? In the light, it shows really bad and looks disgusting. Please someone help
