Ahnfeltia Concinna

What is Ahnfeltia Concinna?

A species of red algae found in coastal waters, used in cosmetics for its gel-forming polysaccharides.

Why is it used in products?

It provides a natural thickening and gelling effect in formulations and is marketed as a clean, marine-derived alternative to synthetic thickeners.

Why does it clog pores?

Like many algae extracts, Ahnfeltia Concinna contains iodides and other halides that can irritate follicular walls and trigger breakouts. Its gel-forming polysaccharides can also create a film that traps sebum. For acne-prone skin, this combination is a recipe for clogged pores.
