What it is
A finely ground powder derived from the red seaweed Palmaria palmata, commonly known as dulse. It contains a variety of beneficial compounds including polysaccharides, minerals (like iodine and potassium), vitamins (such as vitamin C and B vitamins), and amino acids.
How it works
The polysaccharides in Palmaria Palmata Powder form a thin, hydrating film on the skin's surface, helping to lock in moisture and reduce water loss (transepidermal water loss, or TEWL, which is the amount of water that evaporates from your skin). Its antioxidant compounds, like phlorotannins, help neutralize free radicals that can damage skin cells. The minerals and amino acids support the skin's natural repair processes and can help soothe irritation.
Pros
Gentle hydration
Forms a light, non-greasy film that helps keep moisture in the skin without clogging pores, making it suitable for most skin types.
Rich in skin-supporting nutrients
Contains minerals and vitamins that can help calm inflammation and support the skin's natural repair processes, especially beneficial for stressed or sensitive skin.
Cons and cautions
Potential scent issue
The natural seaweed aroma may be noticeable in some products, which could be off-putting for those sensitive to earthy or oceanic smells.
