Essential Oil Applications, Melaleuca alternifolia|

Background: Sleep is one of the most important factors affecting overall health. During the night, the skin repairs damage caused by daily stresses. Melatonin plays a key role in this process. Toxins are removed, and cellular repair and growth hormone production are increased. Inter alia, this also decreases signs of intrinsic aging. Aims: The current study was intended to demonstrate the impact of a unique fraction of Melaleuca alternifolia (FMA) essential oil, on sleep and skin quality. Methods: The effect of FMA was investigated in vitro on skin cells, evaluating its antioxidant and anti- inflammatory properties, and in an ex- vivo study on human skin biopsies treated with FMA following stress induction. In addition, two clinical studies were performed on volunteers with life- style- related sleep complaints. In one study, sleep was measured using a noncontact monitoring device (Sleep Score Labs, Max). A second study was conducted to assess skin anti- aging effects. Results: In vitro application of FMA reduced IL- 8 and reactive oxygen species (ROS) generation in skin cells. This was confirmed ex vivo through a decrease in inflammatory markers and an increase in antioxidant enzymes after stress induction. Interestingly, FMA also upregulated melatonin-associated genes. Real- world sleep tracking revealed that FMA significantly improved sleep quality, relative to unscented control. In vivo applications also showed a reduction in signs of aging. Conclusion: These results provide initial data to suggest that this unique FMA delivers skin anti- aging benefits via a two- pronged mode of action, improving sleep quality, and reducing skin inflammatory and oxidative stress.
