Ingredients higher up in an ingredient list are typically present in a larger amount. 1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse. It is a: Humectant, drawing moisture into the skin Emollient, helping to soften skin Solvent, dispersing and stabilizing formulas Preservative booster, enhancing the antimicrobial activity of other preservatives Butylene Glycol (or BG) is used within cosmetic products for a few different reasons: Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients. Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness. Carbomer is a synthetic thickening and gelling agent. It's basically the ingredient that gives a lot of serums, gels, creams, and sunscreens their smooth, non-sticky texture. Although legally permitted at very high levels, carbomers are normally used at concentrations below 1%. It also needs to be neutralized to actually thicken, and because it is a large molecule, it doesn't really penetrate the skin barrier. Allergy-wise, the risk is very low. Clinical studies show carbomers have low potential for skin irritation/sensitization even at concentrations up to 100%. A 2024 UK study patch-tested 1,302 patients and found true allergy to the parent group of carbomer to be rare with no confirmed relevant reactions. Corallina Officinalis Extract comes from the small red seaweed that grows on rocky coastlines that feels stiff to the touch because it builds calcium carbonate right into its cell walls. That mineral content is basically its whole selling point: the extract brings calcium, magnesium, and trace minerals along with sugars (polysaccharides) and proteins. This is why formulators use it as a skin-conditioning and hydrating ingredient. Lab testing does back up decent antioxidant activity for this species. A study comparing twelve red seaweeds found Corallina Officinalis stood out for its free-radical scavenging capacity. And a separate study found meaningful radical scavenging plus antibacterial activity from the raw biomass. It's worth being clear that most of this is test-tube work on raw-algae and not a clinical trial on a finished cream. On concentration, a 2020 industry survey found it's used at up to 2% in makeup and skincare. Safety-wise, it's as boring as it gets: the Cosmetic Ingredient Review Expert Panel concluded this ingredient (along with the powder, Thallus Extract, and Hydrolyzed versions) to be safe as used in cosmetics and cited negative sensitization data. There's no meaningful record of it causing allergic contact dermatitis, but be sure to patch test if you are unsure. You'll see algae/seaweed 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 tra
