Alpha Lipoic Acid

Alpha-lipoic acid (ALA) is a coenzyme found in mitochondria, similar to a vitamin, that can eliminate free radicals which accelerate aging and cause diseases. After being absorbed through the intestines, ALA enters cells and, due to its fat-soluble and water-soluble properties, can travel throughout the body without obstruction, reaching any cell to provide comprehensive benefits to the human body.

Alpha-lipoic acid also increases glutathione levels, providing better protection against UV-induced pigmentation than glutathione itself, thereby protecting the skin from UV damage. This natural antioxidant is produced in the body and can also be taken as a supplement. In clinical trials, alpha-lipoic acid significantly reduces dark spots. It is actually more effective than glutathione in preventing UV-induced pigmentation. Alpha-lipoic acid has a significant inhibitory effect on tyrosinase activity, which increases with the concentration of water-soluble alpha-lipoic acid. At a concentration of 0.1%, the inhibition rate reaches 80.2%, which is significantly stronger than arbutin. Alpha-lipoic acid also significantly inhibits melanin production, with the inhibition rate increasing as the concentration of water-soluble alpha-lipoic acid increases. At a concentration of 0.1%, the inhibition rate of melanin production reaches 71.5%.


Benefits of Alpha-Lipoic Acid Powder

Benefits of Alpha-Lipoic Acid Powder
  1. Anti-inflammatory effects.

  2. Antioxidant protection.

  3. Reduces the expression of key transcription factor proteins that initiate the process of skin pigmentation.

  4. Decreases enzymes that promote melanin production. Alpha-lipoic acid enhances antioxidant enzyme activity, inhibits basal tyrosinase activity, suppresses the production of basal melanin, interrupts the transfer of melanin, and metabolizes melanin in the skin’s surface layer.
