Arbutin & B3 Serum

Arbutin is a naturally occurring antioxidant and skin brightening ingredient derived from the bearberry plant. It works by inhibiting the enzyme tyrosinase, which plays a key role in melanin production (the pigment responsible for dark spots and uneven skin tone). In skincare, especially in products like Alpha Arbutin serums, arbutin is used to:

• Fade hyperpigmentation including sun spots, acne scars, and melasma
• Even out skin tone by slowing down pigment formation
• Brighten dull skin for a clearer, more radiant complexion
• Gently lighten the skin without irritation (unlike some harsher alternatives like hydroquinone)

When paired with ingredients like Niacinamide (B3), the brightening effects of Arbutin are amplified, making it a go-to for anyone targeting pigmentation or uneven tone.

Great question! Arbutin and Alpha Arbutin are often confused but they have some key differences in terms of effectiveness and stability:

Arbutin (also known as Beta-Arbutin)

• Naturally derived from plants like bearberry, cranberry, or blueberry.
• Works by slowly releasing hydroquinone in the skin to inhibit melanin production.
• Less stable and can break down more easily when exposed to light or heat.
• Gentler, but less potent than Alpha Arbutin.

Alpha Arbutin

• A synthetically derived but more stable and refined version of Arbutin.
• Considered a superior, more effective form when it comes to brightening skin and reducing hyperpigmentation.
• Works faster and is more targeted in inhibiting tyrosinase (the enzyme responsible for melanin production).
• More suitable for formulas aiming for visible and quicker results, like high-performance serums.

Alpha Arbutin is the more advanced, stable, and effective form of Arbutin, making it the preferred choice in premium brightening and pigmentation-correcting skincare products, like our Arbutin & B3 skin brightening serum.

Alpha Arbutin, a clinically backed ingredient derived from the bearberry plant, inhibits melanin production to lighten dark spots, melasma, and uneven tone. This Alpha Arbutin serum works deeply in the skin to reduce pigment at the source without irritation or harsh side effects.
