Key Skin Benefits
Deep hydration — Sea moss is renowned for its natural ability to deeply hydrate the skin. Rich in mucilaginous compounds, it may help moisturise the skin and lock in moisture within the deeper layers, resulting in a radiant and supple complexion.
Vitamin & mineral delivery — Sea moss is rich in vitamins A, C, E, and K, as well as minerals like zinc and magnesium, which help to repair and protect the skin barrier, and amino acids necessary for collagen production
Anti-inflammatory & soothing — Sea moss may act as a soothing and calming agent for irritated skin while also combating bacteria. Its natural anti-inflammatory properties help reduce redness, soothe sensitive areas, and promote a balanced, even complexion.
