How to Use the Sun Exposure Skin Age Calculator
More than 80% of visible skin aging is attributed to photoaging caused by sun exposure. This calculator starts from your actual age and adds points for daily sun exposure, sunscreen frequency, smoking, and tanning habits to estimate a skin age. It's not a medically precise measurement — it's a reference indicator meant to show intuitively how lifestyle habits affect skin aging.
Skipping sunscreen regularly lets collagen break down faster and speeds up pigmentation and wrinkles, while smoking reduces blood flow to the skin and is one of the most common accelerators of aging. UVA rays penetrate through windows even indoors, so it's worth wearing sunscreen even on cloudy days or when you're mostly inside. Tanning beds concentrate strong UV exposure into a short time, which can significantly raise both skin aging and skin cancer risk.
