Kojic Acid

Grand Kojic, kojic acid, is a whitening agent that is produced by the fermentation and purification of glucose or sucrose under the action of kojic enzyme. It works by inhibiting the activity of tyrosinase, the enzyme responsible for melanin production. Grand Kojic can also inhibit the activity of n-hydroxyindoleate (DHICA) oxidase and block the polymerization of dihydroxyindole (DHI). This makes it a rare single whitening agent that can simultaneously inhibit a variety of enzymes involved in melanin production.

Tranexamic Acid

GI-TA,Tranexamic acid, is an innovative and highly effective whitening agent that targets melanin reduction and pigmentation reduction. Traditional whitening agents primarily focus on inhibiting the activity of tyrosinase in melanosomes to reduce melanin production. However, these agents only partially inhibit melanin production and accumulation, and achieving a complete block is challenging.

Alpha-Arbutin

Grand Alpha-Arbutin is a highly valued cosmetic ingredient used in skincare formulations. Through a bioenzymatic transformation, it acquires a single α configuration, ensuring exceptional purity and stability.

Glutathione

Grand Glutathione is a naturally occurring compound that is composed of three amino acids: glutamic acid, cysteine, and glycine. It contains a sulfhydryl group, which gives it antioxidant and detoxifying properties. Glutathione can help to protect the skin from damage caused by free radicals and toxins, and it can also help to lighten the skin tone.

β-Arbutin；Hydroquinone-beta-D-glucopyranoside, 4-Hydroxyphenyl-beta-D-glucopyranoside

Grand Arbutin, also known as arbutin, is renowned for its skin brightening and whitening properties and is widely used in cosmetic formulations.

Kojic Dipalmitate

Grand Kojic-D, Kojic dipalmitate, is a derivative of kojic acid that is produced by the fermentation and purification of glucose or sucrose under the action of kojic dipalmitate. It works by inhibiting the activity of tyrosinase, the enzyme responsible for melanin production.

Ferulic Acid

Grand Ferulic, Ferulic acid, is a naturally occurring phenolic compound that is found in plants. It is a powerful antioxidant that can help to protect the skin from damage caused by free radicals. Sodium ferulate and ferulic acid ester, which are derivatives of ferulic acid, retain the essential biological characteristics of ferulic acid.

Mandelic Acid

Grand Mandelic Acid is an aromatic alpha hydroxy acid, soluble in water and polar organic solvents. It is mild and non-irritating, suitable for all skin types, including sensitive skin.  Grand Mandelic Acid can inhibit tyrosinase activity and reduce the production of melanin in the skin. It also can lift off dead skin cells gently and even skin color. So it has the effect of excellent Skin Brightening Properties & Lightening PIH (Post inflammatory hyperpigmentation). Thus, Grand Mandelic Acid is recommended for lotion, emulsion, essence, cream and other pruducts.
