Kelp, a type of large brown seaweed, belongs to the Laminariales order and thrives in shallow ocean waters around the globe. Historically, coastal communities from Asia to the British Isles have harvested kelp, not only as a food source but also for its abundant medicinal properties. Rich in essential minerals like iodine, magnesium, and potassium, as well as vitamins and antioxidants, kelp has been recognized holistically for its ability to support thyroid function, primarily due to its high iodine content. Moreover, it has been used in traditional practices to boost metabolism and support overall health. When it comes to skin, kelp is a treasure trove of benefits. Its high mineral content helps in maintaining skin hydration and promoting a healthy complexion. The antioxidants in kelp, especially vitamin C and E, protect the skin from environmental aggressors and combat signs of aging. The natural polysaccharides in kelp can form a protective barrier on the skin, helping retain moisture and keeping the skin supple. Furthermore, its anti-inflammatory properties help soothe irritated skin, making it a useful ingredient for those with sensitive or acne-prone skin. Modern skincare formulations often incorporate kelp extracts or powders in products ranging from masks and serums to moisturizers, harnessing the myriad benefits this marine wonder offers.
