Sun protection is the catch-all phrase to describe various methods to shield skin from the sun's damaging UVA and UVB rays. Excessive sun exposure is the leading cause of skin cancer (melanoma); it is also the primary cause of premature aging in skin.
Types of Sun Protection
Sun protection methods include sunscreen, sunblock, sun protection clothing, wash-in sunscreen for clothes, and general avoidance of the sun by staying in shady areas, wearing a protective hat, or staying indoors. Dermatologists advise that individuals use at least a broad-spectrum SPF 30 sunscreen daily, and year-round, to protect skin from even incidental sun exposure.
Protecting skin from sun exposure after a skin treatment
It is important to also remember that following many cosmetic procedures, especially chemical peel and laser resurfacing, the skin is vulnerable and more susceptible to sunburn and sun damage. Sun protection is necessary to ensure the skin is not harmed as it heals.
