What color undertones can self-tanners produce if not applied correctly?

Self-tanners, when not applied correctly, can often result in orange or uneven patches on the skin. This occurs primarily due to the reaction of the dihydroxyacetone (DHA), which is the active ingredient in many self-tanners, with the amino acids in the skin. If the self-tanner is not evenly distributed or if the application is rushed, certain areas may absorb more DHA than others, leading to discoloration.

The presence of orange tones is commonly associated with a poor application technique, where excess product accumulates, especially in areas with texture like elbows or knees. Factors such as skin type, hydration levels, and preparation (like exfoliation) further influence this uneven appearance. Thus, when self-tanners are not applied with care, they can create a patchy and unnatural look, which is why it’s essential to understand proper application methods and skin preparation to achieve a smooth, natural tan.
