MELATONIN

Description

Melatonin, primarily known for its role in regulating sleep cycles, has emerged as a powerful antioxidant in skincare formulations. This hormone, naturally produced by the pineal gland, exhibits significant free radical scavenging properties when applied topically. Melatonin's ability to penetrate the stratum corneum makes it an effective ingredient for combating oxidative stress and UV-induced damage in the skin.

In skincare products, melatonin typically appears in concentrations ranging from 0.1% to 1%. It works synergistically with other antioxidants like vitamin C and E, enhancing their protective effects. Studies have shown that topical melatonin can reduce the appearance of fine lines and wrinkles, improve skin elasticity, and promote a more even skin tone.

Melatonin also demonstrates potential in addressing hyperpigmentation by inhibiting melanogenesis. Its anti-inflammatory properties make it suitable for sensitive skin types and those prone to redness or irritation. Furthermore, melatonin has been observed to support the skin's natural repair processes, potentially accelerating wound healing and reducing the signs of photoaging.

When formulating with melatonin, it's crucial to consider its photosensitivity and incorporate it into night-time skincare routines for optimal efficacy.
