Ingredients higher up in an ingredient list are typically present in a larger amount. Algae Extract is one of the vaguest names on any label because it just means "extract of some alga" (and there are thousands of species and dozens of ways to extract them). This just means two products listing it can contain completely different things. This ingredient name was actually officially retired in the INCI dictionary in 2015 and brands were pushed toward species-specific names instead (like Laminaria Digitata Extract or Chondrus Crispus Extract). Generally, it is used to hold water and soften skin in a formula. Algae are rich in polysaccharides, pigments, and amino-acids that act as humectants, emollients, and skin-conditioning agents. It isn't on standard cosmetic-patch test panels and "seaweed dermatitis" is actually an acute irritant reaction to algal toxins in seawater and not the cosmetic ingredient. You'll see algae listed as a 5/5 on a lot of pore-clogging charts and that number doesn't come from anywhere; it's not in the original rabbit-ear studies that most comedogenic ratings trace back to. The reasoning behind the reputation is that seaweed is high in iodine and iodine can trigger acne-like breakouts when eaten. This traces back to a 1976 letter in Archives of Dermatology describing two women whose breakouts cleared after they stopped taking high-dose kelp supplements orally. And the reaction of these two women wasn't clogged pores at all: it was an iodine-triggered pustular rash. Later research found normal dietary iodine doesn't meaningfully affect acne either and nobody has shown topical algae delivers enough iodine to matter. What we do have is dozens of brown and red algae ingredients found to be non-irritating and non-sensitizing, and a handful of studies that found algae compounds may actually help acne. However, plenty of people do report breaking out from algae-containing products. Skin is individual and it's worth avoiding if yours has reacted to algae before. Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum. Topically, glycerin does several things at once: Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3. Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin. This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products. Just know very high concentrations (>40%) can feel tacky in low humidity. Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine. Phenoxyethanol is
