Photoaging — Conditions

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

Photoaging is known to result from UV radiation damaging 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 pigmentation. Cumulative sun exposure is cited as the background that accelerates changes distinguishable from intrinsic aging.

How to manage

Applying a sufficient amount of sunscreen daily and reapplying every two to three hours is recommended as the fundamental approach. Antioxidant ingredients such as vitamin C and retinol-class ingredients may help support collagen maintenance. Using physical protection such as hats and sunglasses in combination is advisable. If pigmentation or changes in wrinkles are a concern, consulting a dermatologist may be helpful.

Good to know alongside

Photoaging is commonly discussed in relation to UV radiation (UVA/UVB), collagen and elastin loss, hyperpigmentation, and is recognized as a topic in aging skin that is contrasted with intrinsic aging.

Everyday care tips

UVA penetrates through clouds and indoor window glass, so making a daily habit of applying sunscreen — regardless of weather or whether you are indoors — is known to be helpful.
