BETULA PLATYPHYLLA JAPONICA JUICE.

Valuable CAS 223748-09-2 / SKIN CONDITIONING

Commonly known as Birch Sap, this nutrient-dense botanical fluid serves as a superior alternative to deionized water in precision formulations. It delivers a bio-available complex of minerals and sugars that mirror the skin's natural moisturizing factors to optimize cellular hydration.

Humectant Skin Conditioning Agent Anti-inflammatory Barrier Repair

Science

It functions as a multi-level humectant and barrier-restorative agent. By supplying essential amino acids like glutamine and leucine alongside electrolyte minerals (calcium, magnesium), it maintains osmotic pressure within the skin cells, while its natural xylitol and glucose content reinforce the lipid barrier and neutralize oxidative stress through its flavonoid profile.

Key findings

  1. 01 A 28-day clinical trial involving 67 sensitive-skin subjects demonstrated significant reductions in TEWL and visible redness, with 83.87% reporting improved skin comfort.
  2. 02 In vitro analysis confirms that concentrations between 6.25% and 50% stimulate keratinocyte and fibroblast proliferation, supporting accelerated tissue regeneration and anti-aging pathways.

Because it is often used as the formula base (replacing water), it is rarely 'dusted' in high-end skincare; however, in mass-market products, inclusion below 5% may fail to provide the clinical regenerative benefits seen in higher-dose studies.
