Dr. Thomas also said that everyone should be wearing sunscreen regardless of skin tone. Most people wear sunscreen to prevent skin cancer but people of color should be wearing it to reduce wrinkles, skin texture changes, and discoloration. For children, Dr. Thomas suggests that if they are under 6 months then you should not apply sunscreen, just cover them up. When your child is 6 months they can start wearing sunscreen on the exposed areas only. The highest a childs sunscreen SPF should be is SPF 30.
