Rating (out of 5): 2

Birtch (Betula spp.) has a long history of use in traditional medicine, particularly in Europe and parts of Asia, for supporting skin health, including the treatment of dry or flaky skin. Birch leaves, bark, and sap have been used in folk remedies as topical treatments, baths, and infusions due to their purported anti-inflammatory, astringent, and moisturizing properties. Historically, birch oil (often derived from the bark or buds) has been included in ointments and creams aimed at soothing irritated or dehydrated skin, and birch sap is sometimes applied directly for its hydrating effects.

Scientific evidence for birch’s effectiveness in treating dry or flaky skin is limited. Some laboratory studies have identified that birch contains compounds such as betulin, betulinic acid, and various flavonoids, which exhibit anti-inflammatory and antioxidant effects. These actions may theoretically benefit skin barrier function and hydration. However, clinical trials specifically evaluating birch preparations for dry or flaky skin are lacking. Most available evidence remains anecdotal or based on traditional use rather than rigorous scientific validation.

In summary, while birch is traditionally used to support skin health and relieve dryness, current scientific validation is minimal. Its use is primarily justified by traditional practices, with some supportive but indirect evidence from laboratory studies on its bioactive constituents.
