Topically applied <scp>l</scp>‐carnitine effectively reduces sebum secretion in human skin

Abstract

Our results show that the treatment of human sebocytes with L-carnitine significantly augments β-oxidation and significantly decreases intracellular lipid content in human sebocytes. Topically applied L-carnitine is bioavailable and leads to a significant sebum reduction in vivo. In conclusion, L-carnitine represents a valuable compound, produced naturally within the body, for the topical treatment of oily skin in humans.
