Carnitine

This ingredient is also known as Levocarnitine or L-Carnitine. It is an amino acid derivative naturally found in our bodies.

Biologically, carnitine plays a key role in cellular energy production. It transports fatty acids into the mitochondria (say it with me, "the powerhouse of the cell") where they are converted into cellular fuel.

In skincare, this process helps regulate sebum production. One study found topical L-carnitine can help reduce excess oil and improve skin oil balance. This makes it a great addition for oily or acne-prone skin.

Besides oil control, carnitine supports healthy skin metabolism by boosting lipid breakdown. Research has shown it can improve skin’s resilience against aging and external stressors like UV exposure.

There are no downsides to using this ingredient and it is a great multifunctional ingredient for both sebum regulation and anti-aging care.
