Thank you for your question. There are two parts to your question. First is about change in skin colour. You do not mention any additional symptoms like itching or burning or discomfort with heat or cold. Sometimes skim changes can be due to local infections whilst others can be part of a wide systemic problem. A skin specialist can help. Skin lesions need to be seen to be treated effectively. Over the counter remedies may not work. The second question is about excess hair. Laser is very effective at permanently reducing hair on various parts of the body. Again a skin specialist with facilities to use laser will be ideal. best wishes
