What is melatonin? <\/h2>\n\n\n\n
\"Reading<\/figure>\n\n\n\n
<\/p>\n\n\n\n
You sink into bed and close your eyes after a long day. As you drift off, your body begins its natural repair mode\u2014and one of the key players behind this process is melatonin.<\/p>\n\n\n\n
Melatonin is a naturally<\/strong> <\/strong>occurring hormone<\/strong>. Its main function? Helping to regulate the sleep-wake cycle. Your body\u2019s circadian rhythm kicks off its production at night to help you get to sleep.<\/p>\n\n\n\n
But that’s not its only role. Melatonin is also important to the gut, thyroid, lungs, kidneys, and you guessed it, the skin, where it shows off two main strengths: antioxidant and repairing actions.<\/strong><\/p>\n\n\n\n
What role does melatonin play in the skin?<\/h3>\n\n\n\n
At night, as your skin switches from protect mode to repair mode, melatonin production kicks into gear to help it recover from the day\u2019s stresses. And this is no small feat. Your skin makes even more melatonin to help repair itself<\/a> than your brain does to help you fall asleep.<\/p>\n\n\n\n
What\u2019s its role exactly? Melatonin supports skin regeneration and antioxidant activity<\/strong>, helping neutralize free radicals (unstable molecules that can damage cells and accelerate visible aging).<\/p>\n\n\n\n
By reducing oxidative stress, melatonin helps support collagen, elasticity, and an even tone\u2014key for smoother, youthful-looking skin.<\/p>\n\n\n\n
How does topical melatonin work?<\/h2>\n\n\n\n
\"Topical<\/figure>\n\n\n\n
<\/p>\n\n\n\n
Topical melatonin works similarly to the melatonin your skin produces naturally. Research shows<\/a> that it supports overnight recovery and helps prepare your skin\u2019s defenses for the coming day<\/strong>.<\/p>\n\n\n\n
In skincare products, melatonin acts as\u00a0an antioxidant. As it sinks into the skin, it helps repair damage accumulated during the day.<\/p>\n\n\n\n
Something else to keep in mind? Natural melatonin levels decrease with age, so using topical formulas in your skincare routine can lend a helping hand. And especially at night\u2014here\u2019s why:<\/strong><\/p>\n\n\n\n
