CAMELLIA JAPONICA LEAF/SEED WATER.

Valuable / SKIN CONDITIONING

A refined botanical hydrosol derived from the Red Camellia, prized for its high concentration of protective polyphenols. This nutrient-dense aqueous base serves as a bioactive alternative to plain water, providing immediate soothing effects while fortifying the skin's defense against environmental stressors.

Antioxidant Soothing agent Skin-conditioning solvent Anti-photoaging

Science

Operates through a multi-pathway approach: it neutralizes reactive oxygen species (ROS) to prevent oxidative damage and inhibits matrix metalloproteinase-1 (MMP-1) to preserve collagen integrity. Furthermore, it regulates pigment production by inhibiting tyrosinase and strengthens the lipid barrier to significantly reduce transepidermal water loss.

Key findings

  1. 01 Demonstrated significant reduction in UV-B induced erythema and skin thickening at 1.0% concentration.
  2. 02 Inhibition of collagen-degrading enzymes (MMP-1) and stimulation of Type I procollagen in human dermal fibroblasts.
  3. 03 Promotion of DNA damage repair via the FUNDC1-mediated mitophagy pathway in skin fibroblasts.

Because it can be used as a primary solvent (up to 100%), it is rarely 'dusted' in the traditional sense; however, concentrations below 0.1% may fail to provide the anti-inflammatory benefits seen in clinical literature.
