L-Carnitine (also known as Carnitine) is an amino-acid derivative found in the skin and is produced from the amino acids lysine and methionine. It plays a key role in energy production within the cells. It activates cellular ß-oxidation (“fat burning”) and reduces intracellular lipid content.

Additionally, Carnitine regulates the production of sebum by promoting the uptake of fatty acids in the mitochondria, converting them into energy. Thus, the fatty acids can no longer be converted into sebum, and the amount of sebum is substantially reduced. Localized application of Carnitine on the skin helps to significantly reduce the amount of sebum.
