Grand DHA

Grand DHA is a colorless sugar that reacts with the amino acids present in the outermost layer of the skin, known as the stratum corneum. This reaction leads to the formation of a brown pigment called melanoidins, resulting in a temporary tan or bronzing effect on the skin. It is a 3- carbon sugar derived from plant sources such as sugar cane or sugar beets. It has the chemical formula C3H6O3 and is classified as a reducing sugar. In the production of selftanning products, DHA is typically derived from these natural sources or can be synthesized in a laboratory.

When DHA comes into contact with the amino acids present on the skin’s surface, a nonenzymatic chemical reaction known as the Maillard reaction occurs. This reaction primarily takes place with the amino acid groups of the proteins present in the stratum corneum. As a result of the reaction, brown-colored melanoidins are formed, which stain the outer layer of the skin, providing a tan appearance.

INCI Name: Dihydroxyacetone

CAS Number: 96-26-4

Benefits of Grand DHA:

Safe and Non-toxic: DHA has been approved by regulatory bodies such as the U.S. Food and Drug Administration (FDA) for topical use in self-tanning products. It is considered safe and non-toxic when used as directed, with minimal risk of adverse reactions or skin irritation.

Natural-looking Tan: DHA produces a natural-looking tan effect on the skin. Unlike traditional tanning methods that involve exposure to ultraviolet (UV) radiation, which can be harmful, DHAbased self-tanning products offer a safer alternative to achieve a sun-kissed glow without the need for sun exposure.

Temporary Results: One of the benefits of DHA is that the tan it provides is temporary. As the outer layer of skin naturally sheds over time, the tan gradually fades away, typically lasting for about 5 to 7 days. This allows individuals to control and customize their tan without longlasting commitment or permanent color change.

Quick Results: DHA provides an almost instant tan effect on the skin. After the application of self-tanning products containing DHA, the tan develops within a few hours, allowing individuals to achieve a desired look without the need to spend hours under the sun.

Sun Protection: Although DHA does not provide any inherent protection against UV rays, selftanning products that contain DHA often include additional ingredients like sunscreen. These products can provide a temporary tan while also offering protection against harmful UV radiation when used as directed.
