What is Arbutin ?
Arbutin is a widely used skin lightening agent derived from hydroquinone. It is all-natural and can be extracted from bearberry, cranberry, blueberry, and pears. However, synthetical production is also possible through the action of acetobromoglucose on hydroquinone.
Arbutin’s power in reducing hyperpigmentation has been proven and confirmed by various researches over the years. A 2018 study published in Cosmetic Facial Surgery found that arbutin effectively reduced melanin content to approximately 39 percent.
Aside from skin lightening, arbutin also has antioxidant properties that can help improve skin texture. It’s also used in anti-aging products because of this characteristic.
Alpha arbutin (4-hydroxyphenyl α-glucopyranoside) is the purest form of arbutin available. It is also soluble in water, making it easier for the skin to absorb.
Here’s something to note about products that contain alpha arbutin. They are generally expensive because of high manufacturing cost. So if you see a cheap product that claims to contain this ingredient, you may want to think twice.
Products with alpha arbutin are very effective in skin lightening. With the right concentration, the presence of this agent can greatly benefit those who suffer from hyperpigmentation.
