As the demand for natural products continues to grow, many scientists have turned to the sea for developing new skin care products. The sea is filled with nutrients and naturally occurring chemicals that may benefit the skin. because of the wide variety of creatures that live in the ocean, there is a broad spectrum of bioactive compounds that can be harnessed to enhance our health. cosmetic and skin rejuvenation therapies are now developing from the rich source of marine-derived and naturally- occurring compounds in the oceans. Products and spa treatments that harness the healing remedies that the sea provides are becoming very popular among consumers. Here are a few ways that marine compounds may be promising for the skin: F Clinical Trials Unit.

Marine-derived bioactives contain several compounds that may bolster the skin’s natural antioxidants. For example, algae and several marine organisms can secrete several compounds, such as carotenoids and phlortannins, that have both antioxidant and sun protective functions. While these compounds don’t penetrate the skin well, they are effective in topical application since they can stay on the skin’s surface and act as antioxi- dants and UV absorbers. While these compounds should not stop the use of sunscreens, they may be a great addition to a sun-protective regimen that includes a broad-spectrum sunscreen. 2. 36 PULSE ■ January/February 2018 Sugars from the Sea Marine organisms have a host of sugars known as polysaccharides that have been shown to have several beneficial actions. One group of sugars are known as sulfated polysaccharides, which are found in brown, red and green algae. Some of these compounds include fucoidan and carrageenan. These compounds have antioxidant actions that can act to protect both the epidermis and the dermis and one study has shown that they may be protective against UV radiation. Other polysaccharides have anti-inflammatory effects and can block the action of the skin’s oil-producing cells, known as sebocytes. Another polysaccharide from the sea is chitosan that has been studied for its ability to help in wound healing. Chitosan has been shown to improve collagen synthesis in the skin, which is good for healing wounds and may also improve the appearance of aging skin. With the diversity of sugars and actions present in marine water, taking a complementary approach can help
