Alpha Arbutin: A Safe & Effective Natural Skin Lightener April 06 2017
Alpha Arbutin is completely safe and naturally derived from the leaves of the Bearberry (Arctostaphylos uva-ursi). It has been proven in clinical studies to prevent the formation of melanin and lighten the skin. This is great news for those who not only wish to improve their skin and eliminate pigmentation issues, but continual use will also prevent built up of pigmentation caused by sun damage and aging.
Alpha Arbutin is considered a safe alternative to hydroquinone, and is a valuable antioxidant that benefits skin greatly. While others might try to say that there could be side effects, it's a proven medical fact per studies recorded in the NCBI that there are no supportive findings to suggest that alpha arbutin is anything but very safe and effective.
Arbutin is used in skin lightening treatments designed for long term and regular use. An active agent in brands of skin lightening preparations, it is more expensive than traditional skin lightening ingredients like hydroquinone, which is now banned in many countries. In vitro studies of human melanocytes exposed to arbutin at concentrations below 300 μg/mL reported decreased tyrosinase activity and melanin content with little evidence of cytotoxicity.
While there are sources that suggest that there is not enough evidence to suggest that arbutin is effective - it would be true that they haven't done their research. There are several significant studies that show alpha arbutin works very well and is a worthwhile alternative to harsh and synthetic skin lightening ingredients.
