Plant Extract (Salix alba)
Willowbark extract is often called "nature's aspirin" because it contains salicin, which is chemically similar to acetylsalicylic acid (aspirin). It provides gentle beta-hydroxy acid (BHA) exfoliation without the harshness of synthetic salicylic acid. It unclogs pores, reduces inflammation, and helps control excess oil. It's a gentler alternative for those who can't tolerate salicylic acid and offers the added benefit of anti-inflammatory properties.

Willowbark comes from the white willow tree (Salix alba), native to Europe and Asia. The bark is harvested sustainably from managed trees or coppices. It's one of the oldest herbal medicines—used since ancient Egyptian times. The extract is made by extracting salicin from the bark.

Plant Extract (Hamamelis virginiana)
Witch hazel is a plant extract that's been used for centuries as a natural remedy for skin conditions. It contains tannins and polyphenols that give it astringent properties—meaning it can temporarily tighten skin and shrink pores. It also has anti-inflammatory and antioxidant properties. Commercial witch hazel is often distilled, which removes some of the beneficial compounds, so look for alcohol-free versions with the full extract for maximum benefits.

Witch hazel comes from the leaves and bark of Hamamelis virginiana, a shrub native to North America. Native Americans used it for centuries before European settlers adopted it. The leaves and bark are sustainably harvested, and the extract is made by steeping the plant material in water or alcohol.
