Betula Alba (Birch) Juice

Betula alba (birch) juice is a hydrating skin care ingredient derived from the Betula alba birch tree. It’s also commonly referred to as birch juice. Unlike maple or most other types of sap, birch juice is clear and doesn’t have much flavor, it’s just slightly sweet. The juice is a good source of trace minerals like manganese as well as various amino acids, all of which make it a good natural hydrator for skin--but more research is needed before we have a complete understanding of how the various nutrients in birch juice benefit skin (or when the juice is consumed, as birch sap has seemingl…

Betula alba juice appears to work by activating genes responsible for maintaining the skin barrier. Notably, research suggests it can upregulate AQP3 and occludin—proteins essential for barrier function and cell-to-cell communication—in a way that differs from some synthetic alternatives.The ingredient also inhibits enzymes (KLK5 and hyaluronidase) that can compromise barrier integrity, whilst simultaneously suppressing inflammatory and oxidative stress pathways through mechanisms including COX2 inhibition.

Betula alba juice is typically found in toners, essences, and treatment serums. Apply to clean skin using a cotton pad or by patting into the skin with fingertips. It can be used as part of a morning or evening routine, and may be layered with other skincare products. Start with regular use and adjust frequency based on your skin's response.

Betula alba juice is generally considered well-tolerated. Those with known sensitivity to birch pollen or birch-derived products should exercise caution, as cross-reactivity is theoretically possible.
