Topical Melatonin and Polypodium leukotomoas have been shown to be more effective and powerful antioxidants for the specific neck and decollete area. Polypodium leukotomoas is a natural plant based extract derived from the fern leaf that protects DNA from the harmful effects of UV light and environmental pollutants. Melatonin is a hormone naturally made in the pineal gland that helps with sleep but does not induce sleep when applied topically. When we sleep, our bodies go into restoration mode with increased cellular rejuvenation and energy repletion. This powerful antioxidant has the same effect on the skin. It helps increase antioxidant enzyme production and supports our natural repair functions. It is an effective defense against UV rays and helpful for anti-aging goals. Antioxidants such as Vitamin C or L-ascorbic acid can be irritating and proinflammatory to the delicate skin of your neck and decollete.
