Hello, As the pandemic started I started using wash hands regularly and applying sanitiser. In some occasions I applied sanitiser after washing hands. So before this my hands were fair (I am dusky) but after 3 months and I also didn't notice this , but the skin over finger joints and just below nails has darkened in comparison to before. Looks like I have applied something dark there. Also the darkening is more in right hand. I don't user moisturiser much and also my utensil cleaning also has increased. What to do? Is this due to hand washing or using sanitiser ? I started using cleaning gloves and applying nivea moisturiser at night for now.
