Ultraviolet (UV) light plays a complex role in skin care, encompassing both beneficial and harmful effects. On one hand, exposure to UV light can aid in the production of vitamin D, which is essential for various bodily functions, including bone health. On the other hand, excessive exposure to UV rays can lead to skin damage, increased risk of skin cancer, premature aging, and other skin conditions.

This duality in UV light’s effects highlights the importance of moderation and protection. While certain controlled exposures may be leveraged in therapeutic settings, such as in the treatment of specific skin disorders, the potential for harmful outcomes makes it essential to balance the benefits against risks.

In contrast, some of the other options reflect narrower perspectives on UV light's role. The notion that it solely promotes tanning overlooks the serious risks associated with UV radiation, and claiming it is used for skin cleansing does not align with established skin care practices. Similarly, while UV light can contribute to skin healing under specific conditions, it is misleading to suggest that this is its primary role without acknowledging the potential for harm.
