Which property is associated with both DHA and aloe vera in cosmetics?

The property associated with both DHA (dihydroxyacetone) and aloe vera in cosmetics is hydration. DHA is primarily known for its role in self-tanning products, where it reacts with the amino acids in the skin to produce a tan effect. However, many formulations containing DHA also include hydrating agents, as the tanning process can sometimes lead to dryness. Aloe vera, on the other hand, is widely recognized for its soothing and moisturizing properties, making it a popular ingredient in a variety of skincare products. Its high water content and ability to penetrate the skin effectively contribute to hydration, making it an excellent complement to DHA in cosmetic formulations.

The other options, while relevant to different contexts in cosmetics, do not align as closely with both DHA and aloe vera as hydration does. Color enhancement is more pertinent to pigments and dyes, healing is more about wound care, and exfoliation refers to the removal of dead skin cells, which is not a primary characteristic of either ingredient.
