My baby is 2 months and 8 days. I have few concerns about her skin. 1. Darkened legs especially knees with acne like tiny spots without bumps 2. Dark patche in mustache area whereas cheeks and chin are much lighter 3. Tiny lines on forehead and neck( like alternative black and white lines) 4. Does hardness of water effect skin colour and texture 5. Few dry patches like tiny circles Kindly clarify my concerns and sorry for such a long list
