Product Description
What Is Arbutin?
Bearberry, blueberry, and cranberry are among the plants that naturally contain arbutin. Because of its brightening and skin-lightening qualities, this glycoside of hydroquinone is typically found in cosmetic products. Arbutin reduces hyperpigmentation and evens skin tone by inhibiting melanin-producing tyrosinase enzyme.
Preparation Method:
Arbutin can be obtained through extraction from plants, or it can be synthesized in a laboratory setting. The synthetic process typically involves glycosylation of hydroquinone using glucose or glucuronic acid to form the glycoside. The ultimate form of beta-or alpha-arbutin is obtained by drying and purifying the high-purity result from this process.

Skin Whitening & Brightening: Arbutin inhibits tyrosinase to reduce melanin production, helping lighten dark spots, freckles, and age spots for a more even skin tone.
Anti-aging Products: It addresses pigmentation and age spots, promoting a youthful appearance by reducing uneven skin tones.
Hyperpigmentation Treatment: Arbutin is effective for treating melasma, acne scars, and sunspots, by fading dark patches and improving skin clarity.
Sun Protection: While not a sunscreen, it complements UV protection by reducing pigmentation caused by sun exposure.
Moisturizers & Serums: It brightens and hydrates the skin, promoting a glowing complexion.
Facial Creams & Toners: Used in these products to refresh and soothe the skin, reducing discoloration.
Dark Spot Correctors: Targeted treatments use Arbutin to lighten dark spots and blemishes.
User Asked Question:
Q: Is Arbutin better than hydroquinone?
A: Arbutin is considered a safer, milder alternative to hydroquinone, which may cause irritation or sensitivity. Arbutin offers similar benefits without the risks associated with hydroquinone.
