KELP FERMENT FILTRATE.

Valuable / SKIN CONDITIONING

Kelp Ferment Filtrate, produced by fermenting Macrocystis pyrifera kelp with Lactobacillus, is a nutrient-rich ingredient designed to optimize skin health. It precisely delivers bioavailable vitamins, minerals, and antioxidants, targeting enhanced hydration, visible anti-aging effects, and a reduction in inflammation. This fermented extract works to refine skin texture and promote a balanced complexion.

Science

Through the fermentation of Macrocystis pyrifera kelp with Lactobacillus, its inherent nutrients are broken down into highly bioavailable vitamins, minerals, and antioxidants. On the skin, it functions as an oil-free moisturizer and emollient, forming a protective film that actively reduces transepidermal water loss and significantly improves hydration, texture, and brightness. Its robust antioxidant properties shield the skin from environmental stressors and oxidative damage. Furthermore, it exhibits anti-inflammatory effects, effectively soothing irritation, decreasing erythema, and minimizing blood pooling. The ingredient promotes new cell growth and collagen secretion, addressing visible signs of aging such as fine lines and wrinkles while enhancing skin elasticity and refining pore size. It also contributes to a balanced skin microbiome, offering potential antibacterial benefits to mitigate acne development.

Key findings

  1. 01 A study on 33 Chinese women demonstrated enhanced skin healing and decreased transepidermal water loss after two weeks of twice-daily application of a Macrocystis pyrifera ferment-containing cream.
  2. 02 In a comparative study, Macrocystis pyrifera ferment alone significantly reduced Balsam of Peru-induced erythema over time, performing comparably to hydrocortisone.
  3. 03 A 12-week clinical study involving 53 women (aged 42-75) revealed significant improvements in the appearance of fine lines on the forehead and crow's feet, glabellar wrinkles, pore visibility, and overall skin smoothness, with benefits observed as early as two weeks, following twice-daily use of a Macrocystis pyrifera ferment-containing cream.
  4. 04 Research indicates that seaweed polysaccharides within such formulations, alongside probiotics from bioferment, contribute to a reduction in skin pore size.
  5. 05 Specific Lactobacillus strains, key to the fermentation process, have been shown to stimulate collagen secretion, thereby improving skin texture and reducing pore visibility.
