Product description:
Nordic Beauty® Birch Sap is a purely natural, highly bioactive active ingredient sourced from the unspoiled nature of Northern Europe. This genuine birch sap is harvested only once a year in the spring (from early April to mid-May), when the trees intensively pump the nutrients stored in their roots into their buds. The silver birch (Betula pendula), Finland’s national tree, has a long tradition in Nordic healthcare and is used topically to promote healing and relieve skin irritations such as eczema or psoriasis.
In cosmetic formulations, Nordic Beauty® Birch Sap stimulates cell renewal, helps retain moisture in the stratum corneum, and improves the skin’s appearance. The fructose it contains serves as an immediate source of energy for skin cells to support cellular regeneration processes. In addition, fruit acids and vitamins effectively protect skin cells from oxidative stress, UV rays, and environmental stressors. The comprehensive spectrum of nutrients also includes glucose, sucrose, essential minerals such as magnesium, manganese, zinc, iron, and phosphorus, as well as free amino acids and enzyme complexes.
In vivo studies demonstrate the high efficacy of the active ingredient, showing a 42% reduction in TEWL as early as 2 hours after application of a formulation containing 20% of the active ingredient. In addition, after 7 days of use, skin moisture increases by 11% (at a 10% concentration) or by 32% (at a 20% concentration), and skin elasticity increases by 38% (at a 10% concentration) or by 44% (at a 20% concentration).
When Nordic Beauty®Birch Sap is used in hair care, its negative zeta potential causes the active ingredient to quickly adhere to the anionic surface of bleached hair. As a result, it diffuses into the hair more quickly than distilled water, noticeably moisturizing and smoothing it.
The sugar components it contains—fructose and sucrose—also form a light protective film on the hair. This hydrophilic active ingredient can be easily and smoothly incorporated into the aqueous phase of any formulation. Outstanding conditioning results are achieved even at the recommended usage concentration of 10–15%.
For maximum performance and a compelling “Waterless Beauty” or “Active Water” concept, the standard water phase of the formulation can be replaced entirely (100%) with Nordic Beauty® Birch Sap. This active ingredient gives end products—such as anti-aging emulsions, cell-regenerating repair serums, refreshing tonics, or luxurious hair care formulations—that decisive edge in Nordic purity, scientifically proven efficacy, and sustainable innovation.
