Do suncreens protect us?

Area of Science:

• Dermatology
• Oncology
• Public Health

Background:

• Sunlight exposure, specifically ultraviolet (UV) radiation, induces significant biological effects on the skin.
• These effects include pathological changes and are a primary cause of photocarcinogenesis.
• Despite public health campaigns promoting sunscreen use, the incidence and mortality of malignant melanoma continue to rise.

Purpose of the Study:

• To review the role of UV radiation in skin cancer development.
• To summarize the evidence regarding the beneficial and harmful effects of sunscreen use.
• To provide practical recommendations for patient photoprotection against photocarcinogenesis.

Main Methods:

• Literature review of scientific articles.
• Analysis of epidemiological data on skin cancer incidence and mortality.
• Synthesis of evidence on sunscreen efficacy and safety.

Main Results:

• UV radiation is a well-established etiological factor in skin cancer.
• Sunscreens provide a degree of protection against UV-induced skin damage.
• Current sunscreen usage and public health strategies may be insufficient to curb rising melanoma rates.

Conclusions:

• Further research into optimal photoprotection is warranted.
• Patients require clear guidance on effective sun protection measures.
• Balancing UV exposure benefits and risks is crucial for skin health.
