Algae contain significant quantities of iodides, which can irritate and inflame the pores, leading to the production of pustules.
Because they contain significant levels of iodine, all varieties of algae can be extremely triggering for pimples.
Iodine is a vital mineral that we all require in our bodies, but too much of it is ejected via our follicles, causing acne and causing irritation to our pores.
Most algae have comedogenic qualities, which means they have a proclivity for clogging skin pores and causing acne.
