Executive Summary: SKIN001’s premium Pearl Powder is a highly purified, fractionated marine biomaterial functioning as a dual-action traditional Chinese brightening mineral complex. Its primary biochemical efficacy is driven by conchiolin protein, a complex biomacromolecule that hydrolyzes into highly bioavailable keratin-compatible amino acids. Once in the stratum corneum, these amino acids stimulate endogenous superoxide dismutase (SOD) activity and downregulate tyrosinase synthesis, effectively inhibiting melanogenesis at the cellular level. Concurrently, the aragonite (crystalline calcium carbonate) fraction provides an immediate optical blurring effect, scattering incident light to diminish the appearance of rhytides and surface hyperpigmentation.
For R&D formulators, our Pearl Powder is milled into strict particle size distributions, allowing precise control over rheology, dermal penetration, and optical performance. Unlike oxidatively unstable synthetic tyrosinase inhibitors (e.g., L-ascorbic acid), this mineral-protein matrix is intrinsically stable and highly synergistic with botanical extracts. It provides lab procurement officers and chemists with a versatile, long-shelf-life active that satisfies both clean-beauty biochemical mandates and immediate tactile formulation requirements.
Formulation Guidelines: To optimize performance based on desired clinical endpoints, SKIN001 categorizes this ingredient into nano pearl powders and ordinary pearl powder (请分为纳米级和非纳米级珍珠粉):
-
Ultra-Nano Grade Pearl Powder (超纳米级珍珠粉 – 80,000 Mesh / 8万目 / <150nm)
-
Usage Rate: 0.05% – 1.0%
-
Solubility: Insoluble, but owing to extreme sub-micron milling, it forms a near-transparent colloidal suspension in aqueous systems without opacifying the base.
-
Phase Integration: Highly reactive due to massive surface area. Must be pre-dispersed in a low-molecular-weight glycol (e.g., Butylene Glycol or Pentylene Glycol) to prevent electrostatic agglomeration. Add to the final emulsion during the cool-down phase (< 40°C). This 80,000-mesh specification is engineered for maximum transfollicular and transdermal penetration of conchiolin peptides directly into the basal layer.
-
Nano-Grade Pearl Powder (纳米级珍珠粉 – <100nm / 0.1μm)
-
Usage Rate: 0.1% – 2.0%
-
Solubility: Insoluble in water and oil; forms highly stable, homogenous colloidal dispersions in aqueous gels and emulsions.
-
Phase Integration: Add to the cool-down phase (< 45°C) to preserve the structural integrity and enzymatic activity of the conchiolin protein. Requires high-shear homogenization to prevent nanoparticle agglomeration and ensure maximum transdermal bioavailability.
-
-
Ordinary Pearl Powder (非纳米级珍珠粉 – 10μm to 20μm)
-
Usage Rate: 1.0% – 5.0%
-
Solubility: Insoluble. Disperses readily in high-viscosity oil phases, anhydrous systems, or dry powder bases.
-
Phase Integration: Highly heat-stable. Add to the heated water or oil phase prior to emulsification (up to 80°C). Primary function relies on the aragonite crystalline structure for optical blurring and sebum absorption rather than deep dermal penetration.
-
Primary Applications:
-
Advanced skin-brightening and anti-aging emulsions (lotions/creams)
-
Color cosmetics (setting powders, liquid foundations) for soft-focus, matte finishes
-
Overnight restoration masks targeting photo-damage and melanin overproduction
-
Mild physical exfoliants and cleansing pastes (utilizing ordinary/non-nano grades)
-
Clean-beauty and traditional medicine-inspired (TCM) active skincare lines
