1. Whitening effect: Alpha Arbutin is considered to be a highly effective whitening ingredient. It can inhibit the activity of tyrosinase, reduce the formation and deposition of melanin, and effectively lighten skin pigmentation problems such as dark spots, freckles and sun spots. At the same time, it evens out skin tone and brightens dull skin.
2. Inhibit melanin production: Alpha arbutin can interfere with the synthesis process of melanin, inhibit the oxidase activity of tyrosine, and block the formation of melanin. This makes it an ideal skincare ingredient that blocks the overproduction of melanin, reducing the risk of hyperpigmentation and blemish formation.
3. Safety and stability: Compared with other whitening ingredients, Alpha Arbutin has higher safety and stability. It will not lose its activity due to light or oxidation, and can maintain its whitening effect for a long time. In addition, alpha arbutin exhibits low irritation to the skin and is suitable for all skin types.
4. Moisturizing and anti-oxidation: In addition to whitening effect, alpha arbutin also has moisturizing and anti-oxidation effects. It can increase the moisture content of the stratum corneum, improve the moisture balance of the skin, and effectively relieve dryness and tightness of the skin. At the same time, it neutralizes free radicals, defends against oxidative stress, and protects the skin from environmental damage.
