Arctostaphylos Uva Ursi (Bearberry)

Definition:
Arctostaphylos Uva Ursi, commonly known as Bearberry, is a small evergreen shrub native to Europe, Asia, and North America. It is characterized by its red berries and leathery leaves, which have been traditionally used for medicinal purposes due to their high content of arbutin, a natural skin-lightening agent.

Use:
In cosmetics, Arctostaphylos Uva Ursi extract is primarily used for its skin-brightening and antioxidant properties. It is often included in formulations targeting hyperpigmentation, age spots, and uneven skin tone. The arbutin in Bearberry extract inhibits the enzyme tyrosinase, which is responsible for melanin production, leading to a more even complexion and reduced appearance of dark spots.

Usage:
Bearberry extract is commonly found in serums, creams, and lotions designed to brighten and rejuvenate the skin. It can be applied topically to the face, neck, and hands, either as a standalone treatment or as part of a skincare regimen. However, it is important to note that Bearberry extract can be sensitizing to some individuals, so a patch test is recommended before regular use. Additionally, it is crucial to use sunscreen during the day when using products containing Bearberry extract, as it can increase the skin's sensitivity to UV radiation.
