Dilsea Carnosa

What is Dilsea Carnosa?

A fleshy red seaweed found in the North Atlantic, used in cosmetics for its moisturizing polysaccharides.

Why is it used in products?

It provides hydration and is marketed as a gentle, marine-sourced skin conditioner in premium skincare lines.

Why does it clog pores?

Like other red algae, Dilsea Carnosa releases sulfated polysaccharides that form a film on skin and trap sebum in pores. It also contains iodide compounds that irritate the follicular epithelium. Acne-prone individuals should watch for this ingredient in marine-themed product lines.
