Dimethyl MEA (DMAE)
What is Dimethyl MEA (DMAE)?
Dimethyl MEA, also known as DMAE, is a naturally occurring compound found in small amounts in fatty fish like sardines and anchovies, used in skincare for its purported ability to firm and tighten skin by stabilizing cell membranes and boosting acetylcholine production. It functions as a precursor to acetylcholine, a neurotransmitter that supports muscle tone, and is often included in anti-aging products for its potential to reduce fine lines and improve skin elasticity. In formulations, it is typically used at low concentrations (1-5%) to avoid irritation.
