What it is
Arbutin is a glucoside found in plants such as bearberry, and it is also produced synthetically for cosmetic use. It is valued for its ability to support a more even-looking skin tone and is commonly paired with sun care to address the appearance of uneven pigmentation. In sunscreens it functions as a conditioning and tone-supporting additive rather than as a UV filter.
Safety & warnings
Arbutin is generally well tolerated at cosmetic use levels. Because it is a glycoside of hydroquinone, regulatory bodies in some markets have considered limits on use and on hydroquinone impurity content; formulators typically control purity accordingly. Sensitive users may patch test before regular use.
Origin & sourcing
Natural or synthetic; arbutin occurs in plants including bearberry (Arctostaphylos uva-ursi), and is also produced synthetically to a defined purity for cosmetic use.
