1.3-Dihydroxyacetone (DHA) is a naturally occurring carbohydrate commonly used in self-tanning products. It reacts with amino acids in the skin's surface to create a temporary bronzing effect, offering a safe and UV-free tanning solution.
Benefits:
-
Instant Tanning: DHA reacts with the keratinocytes in the skin's surface to produce a brownish pigment, giving the skin a natural tan.
-
UV-Free: Unlike sunbathing or UV tanning, DHA achieves a tan without exposure to harmful UV rays, reducing the risk of skin damage.
-
Gentle and Safe: DHA is a non-toxic ingredient suitable for most skin types.
-
Adjustable Shade: By varying the concentration of DHA, different shades of tan, from light to dark, can be achieved.
Uses:
DHA is primarily used in self-tanning products such as lotions, sprays, and mousses. It is ideal for those who want a sun-kissed glow without UV exposure.
Precautions:
-
Even Application: Ensure even application to avoid streaks or uneven coloration.
-
Avoid Mucous Membranes: DHA may irritate mucous membranes like the eyes and lips, so avoid these areas during application.
-
Temporary Effect: The tanning effect of 1.3-Dihydroxyacetone DHA fades as the skin's outer layer naturally sheds, typically lasting 3-7 days.
-
Patch Test: A patch test is recommended before first use to ensure no allergic reaction.
