Masking

Algin is the sodium salt of alginic acid, a sugar-based polymer pulled out of brown seaweed.

In cosmetics, it's a workhorse thickener, binder, and film former rather than an active; it's mostly there for texture and slip.

Industry survey data collected by the Cosmetic Ingredient Review put its maximum reported use at 50% in paste masks and mud packs with reported use going all the way down to 0.001% in aerosol products. Most formulas sit at the low end since a little goes a long way as a thickener.

Allergy-wise, this ingredient is about as low-risk as it gets topically:

The "algae causes acne" idea comes from three places that got tangled together:

None of that transfers to a purified polysaccharide like algin. Clogged pores are a lipid problem where an ingredient has to get into the follicle and mix with sebum to form a comedone. Algin is a big, water-loving sugar chain that does neither; it gels and then sits on the surface as a film until it's rinsed off.
