What is Hyperpigmentation?
Next, there is photo damage (sun damage), another form of hyperpigmentation, which is the most common kind. This occurs when melanin in the skin is exposed to UV radiation from the sun. It is the structural and functional deterioration of sun exposed skin resulting in freckling, fine lines, wrinkling, roughness, altered texture, discolorations, lentigines, mottled hyperpigmentation, epidermal thickening, degeneration of the dermis, degeneration of collagen and elastin, damage to dermal vessels, the presence of skin cancer, and sun spots. Damage to the skin results from prolonged exposure to UV irradiation. It damages the skin's fibers and is the cause of up to 90% of skin aging. Sunscreen use EVERYDAY, rain or shine and use indoors & outdoors can prevent photo damage to the skin. It is recommended that one wears a broad spectrum sunscreen (covering UVA/UVB rays) of at least a SPF30 daily and reapplied every 2 hours. Also, it is best to avoid the sun's rays between the hours of 12-4 pm when they are the strongest, especially during the summer months.
