The sun is “out” every day.
Here’s how it affects you and your skin.
The sun is over 6 billion years old, but it’s still going strong. Some say, stronger than ever. The sun's ultraviolet light covers a wide spectrum: ultraviolet A (UVA) covers the long-wave spectrum while ultraviolet B (UVB) covers the shortwave rays.
The skin is the largest organ of your body. It has three layers: the epidermis (outer), basal (middle) and dermis (inner).
When your skin is exposed to Ultraviolet (UV) rays, cells in your outer epidermis called melanocytes produce melanin, the pigment that becomes absorbed by surrounding skin cells. When melanin is exposed the longer UVA rays, it darkens as it oxidizes, creating a darker complexion.
