Photoprotection in immunocompetent and immunocompromised people

Area of Science:

• Dermatology and Public Health

Background:

• Ultraviolet radiation (UVR) from solar and artificial sources is a primary cause of skin cancer and premature skin aging.
• Skin cancers, including melanoma and non-melanoma types, pose a significant global public health challenge and incur substantial healthcare costs.
• Effective photoprotection, encompassing shade, protective clothing, and sunscreen use, is essential for mitigating UVR's detrimental effects.

Purpose of the Study:

• To provide comprehensive information on UVR and photoprotection strategies.
• To discuss the efficacy and safety of topical sunscreen formulations.
• To address behavioral, educational, and common misconceptions related to photoprotection and skin cancer prevention.

Main Methods:

• Review of existing literature on UVR, skin cancer, and photoprotection.
• Analysis of current photoprotection recommendations and guidelines.
• Identification and discussion of persistent misconceptions regarding sun safety.

Main Results:

• UVR is a major etiological factor for various skin cancers and photoaging.
• Photoprotection measures are vital for both immunocompetent and immunocompromised individuals.
• Misconceptions about photoprotection can hinder effective skin cancer prevention efforts.

Conclusions:

• Adequate photoprotection is the cornerstone of reducing UVR-induced skin damage and skin cancer incidence.
• Education and behavioral interventions are critical for improving photoprotection practices.
• Addressing common myths and errors in photoprotection is necessary for public health.
