Science
Mechanism of Action
GFF operates via a multifaceted biological cascade, supplying yeast peptides, amino acids, and vitamins to stimulate cellular regeneration and metabolic processes, which in turn restore skin elasticity and refine texture. It enhances barrier function through activation of the aryl hydrocarbon receptor (AhR) and upregulation of epidermal proteins like filaggrin, while boosting hyaluronan synthesis for increased hydration. Potent antioxidant activity is driven by NRF2 activation and Reactive Oxygen Species (ROS) suppression. GFF also addresses hyperpigmentation by modulating melanocyte redox balance, exhibits anti-inflammatory properties through promoting IL-37 and downregulating IL-33, and supports a balanced skin microbiome.

Key findings
- 01 An essence containing 97% GFF significantly reduced large opened pores (over 15.66%), blackhead pores (21.84%), sebum (64.17%), and keratin (16.47%). It also improved skin brightness by 2.49% and decreased acne by 9.59% in a study with twenty volunteers.
- 02 A combination serum including GFF effectively treated post-acne hyperpigmentation (PAH) in Fitzpatrick skin types IV and V over 8 weeks, demonstrating increased lightness (L* score) and a reduced melanin index.
- 03 GFF-containing moisturizers were shown to increase skin hydration, reduce transepidermal water loss (TEWL), and improve intraday fluctuations in facial redness, skin roughness, and hair pore size. Daily application for 12 months effectively reversed facial skin aging.
- 04 At a 0.1% concentration, GFF, when combined with Epigallocatechin Gallate (EGCG), inhibited Reactive Oxygen Species (ROS) generation in human keratinocytes.

Dusting Analysis
Clinical studies demonstrate significant efficacy across a wide range of concentrations, with potent effects observed even at 0.1% for antioxidant benefits and comprehensive improvements at 97%. This indicates GFF is effective at active levels, rather than at negligible 'dusting' percentages.
The Formula
Formulation
Stability
GFF has a characteristic fermented aroma that may require fragrance in higher concentrations. While the raw material is susceptible to heat (>40°C) and light, and should be refrigerated, finished products are generally stable at room temperature due to integrated preservatives. Color may transition from yellowish to amber over time without impacting efficacy.
Synergies
- Epigallocatechin Gallate (EGCG) for enhanced antioxidant activity
Conflicts
- High-pH ingredients
- Strong exfoliants
- Products for fungal acne (Malassezia-induced conditions)
Safety
Safety Profile
A tentative CIR report (Jan 2024) deemed GFF safe for cosmetic use, with reported concentrations up to 90.7% in leave-on moisturizing products. It is generally well-tolerated with minimal irritation potential; however, its fungal origin means it is not recommended for individuals with fungal acne or Malassezia-induced skin conditions as it may exacerbate the issue.
