What is DHA primarily used for in tanning products?

DHA, or dihydroxyacetone, is primarily known for its role as an active ingredient in sunless tanning products. It works by reacting with the amino acids in the outer layer of the skin, specifically in the dead skin cells, to produce a brown pigment called melanoidin through a process known as the Maillard reaction. This is what gives the skin a tanned appearance without the need for UV exposure, making it a popular choice for those seeking a tan without the risks associated with sun exposure or tanning beds.

While some products may contain ingredients that could enhance color or serve as fragrances, DHA specifically functions to create a tanned look. This distinguishes it from other options that might not be directly associated with the tanning effect.
