- Arbutin: Some skin lighteners are natural sources of hydroquinone. They include Mitracarpus scaber extract, Uva ursi (bearberry) extract, Morus bombycis (mulberry), Morus alba (white mulberry), and Broussonetia papyrifera (paper mulberry). All of these contain arbutin (technically known as hydroquinone-β-D-glucoside), which can inhibit melanin production. Pure forms of arbutin are considered more potent for affecting skin lightening. Arbutin is derived from the leaves of bearberry, cranberry, mulberry or blueberry shrubs, and also is present in most types of pears. It can have melanin-inhibiting properties. Arbutin is considered safe alternatives to commonly used depigmenting agents to make the skin fairer. Medical studies have shown the efficiency of arbutin for skin lightening.

- Glutathione: This is a tripeptide molecule found in mammalian bodies. It is an antioxidant that plays an important role in preventing oxidative damage to the skin. The role of glutathione as a skin whitening was discovered as a side effect of large doses of glutathione. Glutathione utilizes different mechanisms to exert its action as skin whitening agent at various levels of melanogenesis. It inhibits melanin synthesis by means of stopping L-DOPA’s ability to interact with tyrosinase in the process of melanin production. Research result from a study shows that glutathione inhibits the actual production as well as agglutination of melanin by interrupting the function of L-DOPA. Another study found that glutathione inhibits melanin formation by direct inactivation of the enzyme tyrosinase by binding and chelating copper within the enzyme’s active site. Glutathione’s antioxidant property allows it to inhibit melanin synthesis by quenching of free radicals and peroxides that contribute to tyrosinase activation and melanin formation. Its antioxidant property also protects the skin from UV radiation and other environmental as well as internal stressors that generate free radicals that cause skin damage and hyper-pigmentation.
- Kojic Acid: This is a by-product in the fermentation process of malting rice for use in the manufacturing of sake, the Japanese rice wine. Research has shown kojic acid to be effective for inhibiting melanin production (darkening of the skin).
- Licorice: The compound glycyrrhizin (or glycyrrhizic acid) is found in liquorice and is very effective treating inflammation-induced skin hyperpigmentation. Hyperpigmentation is the darkening of an area of skin caused by increased melanin.
- Papaya: One of the most popular ingredients in skin whitening products because it contains papain, a natural enzyme that promotes skin renewal and cell turnover. It helps in exfoliating the skin to reveal newer cells, and has restorative properties that lightens & softens the skin.
- Plant Placenta: This is the highly bioactive vegetal placental ingredient. The scientific substitute for human or animal placenta as it offers the same efficacy and results. They are particularly noted to have similarity in amino acid content acting as bio-activator for natural skin development, thus revitalizing cells naturally. Plant placenta regenerates and invigorates the skin, enhances the release of stem cells, stimulates cell renewal, improves oxygen supply in our cells and increases protein synthesis in our skin to maintain its radiance and youthfulness. The powerful properties also strengthen skin cells against premature photo-ageing and chronological ageing; thus, concluding the perfect rejuvenated, revitalized, regenerated and lighter skin.
