Algin
Also known as: Alginic Acid, Sodium Alginate
What is Algin?
A polysaccharide extracted from the cell walls of brown algae, commonly used as a natural gelling and thickening agent.
Why is it used in products?
It's a versatile thickener and stabilizer that gives products a smooth, gel-like texture without synthetic additives.
Why does it clog pores?
Algin forms a moisture-trapping film on the skin surface that can seal pores shut. As an algae derivative, it also carries iodides that irritate the follicular lining. This combination of pore-sealing film and iodide content makes it problematic for breakout-prone skin.
