[|Human|] Hello Dr, I am 31 years old. I was a very very fair baby. My parents and siblings are fair. However, my skin color has been getting darker. My trunk from neck till knee are fair but my face, neck and forearms are dark. Especially my face is becoming darker. I would like to be in wheatisChatDoctorplexion if not fair. Can a fair baby become dark over time? Is there any way now at this age, I can reverse it? Thanks for your time and answer. Sami
[|AI|]  Hello the part of the body you are mentioning is less likely to be covered and due to sun exposure it becomes darker. Apply sunscreen. Choose a sunscreen. SPF, or Sun Protection Factor, is a measurement of how well a sunscreen will protect skin from UVB rays, the kind of radiation that causes sunburn. If your skin would normally burn after 10 minutes in the sun, for example, wearing an SPF 15 sunscreen would theoretically allow you to stay in the sun for 150 minutes (10 x 15) without burning. This is a rough estimate, however.30 minutes before you go outside, apply an ounce of sunscreen. Applying sunscreen just before you go into sun will not be effective. Hope this answer helpsRegards
