Sun Protection and Sun-Damaged Skin

Sun damage is the skin change that follows sun exposure, and sun protection is the habit that guards against it. Seen as a timeline, the topic runs from the first faint sign to a daily routine to the point where damage is worth a professional look.

Protection starts as a year-round habit

The CDC says it is important to protect your skin from the sun all year, not just during the summer. The CDC also advises protecting your skin when the UV index is three or higher in your area. That advice applies in St. Johns as much as anywhere. The Skin Cancer Foundation keeps a broader page on skin cancer prevention for readers who want the larger picture.

What the skin does over time

MedlinePlus has a page on aging skin and sunlight, and the Skin Cancer Foundation keeps a page on sunscreen.

Guides can name the stages, but they cannot judge a particular patch of skin. When a mark has changed or protection has been uneven for years, an in-person assessment is the sensible next step.
