CARNITINE FUMARATE.

Valuable CAS 220349-64-4 / SKIN CONDITIONING

A high-performance bio-active salt that bridges the gap between metabolic energy production and surface-level skin refinement. This versatile molecule excels at balancing lipid levels and accelerating cellular renewal without the inflammatory response typically associated with chemical exfoliants.

Sebum regulator Non-acidic exfoliant Mitochondrial energy booster Skin conditioning agent

Science

It acts as a mitochondrial fuel transporter, shuttling long-chain fatty acids into the cell's 'power plants' for ATP synthesis. This metabolic upregulation signals sebocytes to reduce excess oil production while providing a non-acidic keratolytic effect that clears dead skin cells through enhanced biological turnover.

Key findings

  1. 01 Demonstrated a statistically significant boost in ATP concentration within hair follicles for revitalized growth (2% concentration).
  2. 02 Proven to markedly decrease sebum secretion by modulating intracellular fat metabolism in human skin cells (2% concentration).
  3. 03 Validated as a gentle keratolytic agent capable of promoting cell turnover at a skin-neutral pH of 6.0-7.0.

Because it is an effective 'story' ingredient for energy and metabolism, it is often included at sub-clinical levels (<1%). For true sebum regulation and exfoliation benefits, a minimum of 1-2% is required.

Stability

Highly thermally stable up to 200°C but significantly hygroscopic; must be protected from humidity. Optimal long-term stability in solution is maintained between pH 3.0 and 6.0.

Synergies

  • Humectants
  • Hair growth stimulants
  • Mattifying agents

Conflicts

  • Strong oxidizing agents
  • Highly alkaline environments (pH > 8.0)
