Protecting the Skin

Sun exposure causes skin damage. Photoaging is the premature aging of the skin due to prolonged and cumulative sun exposure. Photoaging (photodamage) is a preventable dermatology condition. A mild case is generally characterized by wrinkles, freckles, lentigines, blemishes and telangiectases. Telangiectases are birthmark-type lesions caused by dilation of a group or small blood vessels. Moderate photoaging is generally characterized by tough, rough, thickened, sallow (yellowish) skin and severe photoaging is usually indicated by actinic keratoses (horny, premalignant skin lesions), reduction in skin elasticity and scarring. While aged skin is smooth and unblemished with exaggerated expression lines, photoaged skin has more pronounced wrinkles, lentigines and pigmented lesions like freckles.

UVB rays: Shorter wave lengths that cause visible damage to the skin. UVB primarily affects the skin's outer layers and is the primary cause of sunburn. These rays contribute to skin aging and skin cancer and are more intense during the summer months, at higher altitudes and in areas closer to the equator.

UVA rays: Longer wave lengths that remain constant throughout the seasons. Their effects are cumulative and they penetrate more deeply into the skin. They contribute to photodamage (wrinkling of the skin, premature aging and skin cancer).

• Due to sun-reactive types (fair and sensitive skin)
• Due to skin conditions like Rosacea, Melasma, Actinic Keratosis
• Due to skin medications like Accutane and Retin-A
• Due to therapies like Alpha-Hydroxy Acid
• Due to treatments like cosmetic procedures, peels and lasers

• Facial skin is exposed to UV radiation everyday
• The incidence of skin cancer continues to rise
• Year-round sun exposure for active lifestyles and outdoor occupations
