It is normal that ultraviolet radiation from sunlight affects our skin and darkens it due to extra exposure.

There is a positive contribution of sun rays on the body that it helps in producing melanin and vitamin D. But if there is excessive exposure then ultraviolet rays put a negative impact including sun burn and increased risk of skin cancer and sometimes ageing of the skin.

The laser treatment for tan removal uses a low level of red laser that is applied to the area damaged by the sun rays. The penetration is three inches deep in the skin. This enhances the growth of the new skin cells along with the increase in the production of enzymes, collagen and cell growth. Laser therapy also halts scar tissue from forming and increases the collagen levels in the skin.
