Does the sun help produce melanin?
The outer layer of the skin has cells that contain the pigment melanin. Melanin protects skin from the sun’s ultraviolet rays. These can burn the skin and reduce its elasticity, leading to premature aging. People tan because sunlight causes the skin to produce more melanin and darken.
Does sun exposure change skin color?
Exposure to sun or ultraviolet (UV) light, especially after taking a medicine called psoralens, may increase skin color (pigmentation). Increased pigment production is called hyperpigmentation, and can result from certain rashes as well as sun exposure. Decreased pigment production is called hypopigmentation.
How does melanin disappear?
It is productive to have nonliving protein and fat there rather than having living cells on the surface.” The melanin in these dead cells absorbs some of the UV radiation hitting the skin. During the winter, this cycle of regrowth and shedding continues, but the production of melanin drops off.
How long does skin take to produce melanin?
After an hour, measurable amounts of melanin accumulate, although in relatively small quantities compared to the production that will occur within 24 hours.
Does sun age your skin?

Is sun damaged skin permanent?
