Algae Extract
Also known as: Seaweed Extract, Marine Extract
What is Algae Extract?
A broad term for extracts derived from various species of freshwater or marine algae, packed with minerals, amino acids, and polysaccharides.
Why is it used in products?
It's a skincare darling for hydration, antioxidant protection, and anti-aging claims — you'll see it in everything from serums to sheet masks.
Why does it clog pores?
Algae extracts are high in iodides and sulfated polysaccharides that can irritate hair follicles and promote comedone formation. They also form a biofilm on skin that traps sebum and dead cells inside pores. This is one of the most common hidden acne triggers in "clean" skincare.
