THE IMPORTANCE OF PHOTOPROTECTION IN PREVENTING SIGNS OF SKIN AGEING AND CARING FOR SKIN HEALTH

Abstract

Introduction: Photoprotection is fundamental in preventing signs of skin ageing and in caring for skin health.  Chronic exposure to ultraviolet (UV) radiation accelerates premature aging, characterized by wrinkles, loss of elasticity, hyperpigmentation and other cumulative damage to cellular DNA, as well as increasing the risk of developing skin cancer. Objective: To analyze the relevance of photoprotection as an indispensable strategy for preventing the signs of skin aging and maintaining skin health. Methodology: This study used a literature review methodology to investigate the importance of photoprotection in preventing signs of skin ageing and maintaining skin health. Results and Discussion: Broad-spectrum sunscreens (UVA/UVB) play an essential role in preventing photodamage and photoaging. Ultraviolet (UV) radiation is one of the main causes of premature skin ageing and structural damage to the skin. Broad-spectrum sunscreens offer protection against UVB rays, which cause sunburn, and against UVA rays, which are responsible for deeper damage to the dermis. Studies show that regular use of sunscreens reduces the incidence of changes in the extracellular matrix and protects cellular DNA, preventing mutations associated with skin cancer. Conclusion: The regular use of broad-spectrum sunscreens (UVA and UVB), combined with antioxidants and physical barriers, is essential to reduce the harmful effects of the sun. Adopting healthy habits, such as avoiding intense sun exposure and wearing protective clothing, enhances prevention. Strategies combined with dermo-cosmetics help to delay the effects of ageing and preserve the integrity of the skin.
