What is a common effect of using UV rays on the skin?

Using UV rays on the skin can lead to darkening pigmentation, a response known as hyperpigmentation. This occurs because UV radiation stimulates the melanocytes, the cells responsible for producing melanin, the pigment that gives color to the skin. In reaction to UV exposure, melanin production increases as a protective mechanism to absorb and dissipate the harmful effects of UV radiation. This results in tanning or darkening of existing pigmented areas of the skin.

While other options such as soothing irritation, increasing hydration, or enhancing elasticity may seem beneficial, they do not typically occur as a result of UV exposure. In fact, excessive UV exposure can actually lead to skin damage, inflammation, dryness, and loss of elasticity over time, which further highlights the risks associated with UV radiation.
