INCI name：Lactobionic acid

Skinactive LBA, Lactobionic acid, is a polyhydroxy acid (PHA) that is naturally produced by the fermentation of lactose. It is a gentler exfoliator than other AHAs, such as glycolic acid, and it is less likely to cause irritation. Lactobionic acid is also a humectant, which means that it attracts water to the skin. This helps to keep the skin hydrated and prevent it from drying out.

INCI Name: Dihydroxyacetone

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.

INCI Name: Erythrulose

Grand Erythrulose, also known as Erythrulose, is a chemical compound commonly used in selftanning products. It is a four-carbon sugar with the chemical formula C4H8O4. It is a colorless to pale yellow liquid with a sweet odor. Erythrulose is a ketose sugar, meaning it has a ketone functional group.In self-tanning products, Grand Erythrulose functions similarly to DHA. When applied to the skin, it undergoes a chemical reaction with the amino acids present in the stratum corneum, resulting in the formation of melanoidins, which contribute to a tan appearance.
