In cosmetic-appearance dermatology, it shows up as the look of premature wrinkles, uneven tone and dark spots, leathery surface texture, and overall dullness — most visibly on areas that get the most chronic sun (face, neck, décolleté, and backs of the hands). Patient-facing references from major dermatology and regulatory bodies converge on daily broad-spectrum SPF 30 or higher as the single most consistent long-term lever for the cosmetic appearance of sun damage. Sun Damage is framed here at the cosmetic-appearance layer; medical concerns associated with sun exposure (including skin cancer) are out of scope for this Concern page and belong with a clinician."]},{"heading":"Causes","paragraphs":["The cosmetic appearance commonly grouped under \"sun damage\" is driven primarily by cumulative UV exposure. Two UV bands matter for the daily-wear story:","UVB (~290–320 nm). The burning band. Causes the visible redness and tenderness of sunburn and is the band the SPF number rates. UVA (~320–400 nm). Penetrates deeper into skin, passes through clouds and standard window glass, and is the band most consistently named in patient-facing dermatology references for the appearance of long-term photoaging — premature wrinkles, dark spots, sagging-looking skin, and dullness.","Cumulative UV exposure interacts with several other factors that influence how visible sun damage becomes:","Years of unprotected outdoor time. Commute hours, outdoor work, recreational sun, and reflective surfaces (water, sand, snow) all add up. Tanning behavior — beach and indoor. Both have been linked in patient-facing dermatology references to accelerated cosmetic-appearance aging. Skin tone and individual response. Lighter skin tones generally show UV-driven appearance changes earlier; deeper skin tones can show appearance changes as uneven pigmentation and dullness even when burning is rare. Daily SPF benefit is a cosmetic-appearance lever across all skin tones. Combined exposures. Smoking and chronic alcohol intake are commonly named cosmetic-appearance accelerators alongside sun exposure.","A single topical product cannot reverse decades of accumulated sun-driven appearance change. The strongest long-term lever for the look of sun-damaged skin is preventing further UV insult — daily, year-round."]}],"ranked_product":{"title":"EltaMD UV Clear Broad-Spectrum SPF 46","url":"https://skinknowledgebase.com/products/eltamd-uv-clear-spf-46"}}
