Your skin works as a complete system, called the melatoninergic system, for producing, regulating, and receiving melatonin. But, as you age, both the amount of melatonin as well as the density of melatonin receptors decreases, impairing your skin’s ability to use this precious molecule.
Luckily, studies show that the topical application of melatonin can reverse the decline of melatonin levels as you age.
