What type of products can individuals use to achieve tanning without UV exposure?

The correct choice highlights products designed specifically to create a tanned appearance without using ultraviolet (UV) light, which is beneficial for those looking to avoid skin damage associated with tanning beds and sun exposure. Bronzers, self-tanning products, and spray tans work by applying color to the skin's outer layer through ingredients such as DHA (dihydroxyacetone), which reacts with the amino acids in the skin to produce a brownish tint.

This method allows individuals to achieve a tanned look instantly via bronzers or gradually with self-tanning products, all while eliminating the risks associated with UV radiation, which can lead to skin cancer and premature aging. Spray tans provide a professional application option, ensuring even coverage and preventing streaks.

The other choices do not align with the goal of tanning without UV exposure. Indoor tanning lotions are typically used in conjunction with UV exposure from tanning beds, while UV lamps and sunbathing oils exacerbate UV exposure, counteracting the intention of sunless tanning products.
