Challenges in Sun Protection.

Area of Science:

• Dermatology and photoprotection research.
• Cosmetic science and product development.
• Public health and consumer education.

Background:

• Historical use of sun protection methods predates modern sunscreen products.
• Early 20th-century association of tanned skin with health contrasted with the need to prevent sunburn.
• Development of the first sunscreen products around 1945 marked a significant advancement in solar radiation protection.
