Arbutin works similarly to the whitening agent hydroquinone by inhibiting the activity of tyrosinase and reducing the formation of melanin. However, arbutin has a lower level of irritability compared to hydroquinone due to the presence of glucose molecules in its structure. This allows it to be used in skincare products without causing significant irritation.
In addition to its ability to inhibit tyrosinase and prevent the formation of melanin, arbutin also has anti-inflammatory properties and can accelerate the breakdown of existing melanin. These properties make it a popular ingredient in whitening products.
However, it's important to note that arbutin can cause melanin precipitation when used in high concentrations during the day. To comply with regulations and ensure safety, cosmetic products typically contain arbutin at levels below 3%, which is well below the limit set by regulatory authorities. Therefore, it is safe to use products containing arbutin during the day.
You can find arbutin in various skincare products, including moisturizers, cleansers, and serums, such as the Water Moisturizing Whitening Facial Cleanser, Water Moisturizing Whitening Toner, and Water Moisturizing Whitening Essence.
