What is Photoaging?

UV-induced skin aging that differs from natural chronological aging

Destruction of collagen and elastin causes deep wrinkles, uneven pigmentation, and loss of elasticity, accounting for up to 80% of total skin aging.

Main causes & characteristics of Photoaging

Photoaging is known to result from ultraviolet radiation damaging the collagen and elastin fibers in the dermis. UVA penetrates deep into the dermis and is known to cause deep wrinkles and loss of elasticity, while uneven melanin production may lead to hyperpigmentation. Cumulative sun exposure is cited as the background factor that accelerates changes distinguishable from chronological aging.

Managing Photoaging

Applying a sufficient amount of sunscreen daily and reapplying every 2 to 3 hours is recommended as the fundamental management approach. Antioxidant ingredients (such as vitamin C) and retinol-class ingredients may help with collagen support, and it is advisable to use physical protection such as hats and sunglasses as well. If pigmentation or wrinkle changes are of concern, consulting a dermatologist may be helpful.
