Description and Application:

Alpha-arbutin is similar to arbutin, which can inhibits the production and deposition of melanin, remove spots and freckles. Studies have shown that α-arbutin can inhibit the activity of tyrosinase at a relatively low concentration, and its inhibition effect on tyrosinase is better than the arbutin, but its price is slightly higher. Alpha-arbutin is characterized by rapid whitening and brightening of the skin, and the whitening effect is stronger than the β-arbutin, which is suitable for all skin types.
