  • Acts As A Powerful Hydrocolloid: Irish moss traditionally has been valued for its hydrocolloid composition (2). Hydrocolloids help retain healing fluids over a wound to protect it from the outside environment.
  • Helps Treat Acne: Experts claim that the high sulfur content of sea moss may help lower excess sebum production on the skin. The antibacterial properties of sea moss may also help treat acne. However, more research is warranted in this regard.
  • Hydrates Skin: Irish moss is non-comedogenic. It contains 15 of the 18 essential elements that make up the human body – including calcium, magnesium, and vitamin K (3). It also contains vitamin A and omega-3 fatty acids. These nutrients hydrate skin and aid healthy skin cell functioning (4). They may also offer anti-aging benefits, prevent winter dryness, and protect the skin from the damaging effects of the environment. Sea moss is also thought to treat skin conditions like eczemai  A chronic skin condition that causes dryness, irritation, blisters, inflammation, and red rashes on the skin. and psoriasisi  A common, chronic skin condition that causes itchy and scaly patches on the skin, often triggered by a cold, infection, or stress. , though more research is needed to support this claim.
  • Reduces Skin Inflammation: The vitamin A and omega-3s in sea moss may help fight skin inflammation.
  • May Promote Scar Healing: As sea moss is a type of red macro-algae, it may be rich in agaroid and carrageenan. These compounds have great potential in scar healing and skin regeneration. Agaroid demonstrates biocompatibility and high affinity to absorb water. When used in wound dressings alongside collagen or gelatin, agaroid may promote tissue repair while minimizing scarring and leaking of fluid. Carrageenan may help stimulate immune cell activity. When incorporated into wound dressings, it may create flexible, transparent, and mechanically strong hydrogels with effective fluid absorption. These findings highlight the potential of sea moss derivatives in promoting scar healing and enhancing wound dressings for improved skin regeneration (5).

A blogger using the name Melanin Mommy Magic shared her experience using sea moss for both dietary and skincare purposes. She had incorporated sea moss into her diet through smoothies and yogurt, noting potential improvements in mood and energy. She writes, “I noticed a clear difference in my blemishes, pores, and brightness after only 3 treatments. I was actually in disbelief (i).”
