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 Acrylates/C10-30 Alkyl Acrylate Crosspolymer is a synthetic polymer. It is used to thicken, emulsify, and improve the texture of products. As an emulsifier, it helps stabilize oil-in-water emulsions to give products an elegant feel when applied. It can also form a thin protective film on skin. One study found that a formula using this polymer helped slow down how quickly other ingredients (like DEET) were absorbed through skin. A 2024 study of over 1,300 patients confirmed that sensitization to this ingredient is rare. It is also non-mutagenic and has a clean track record. Beta-Glucan is a soluble polysaccharide (a chain of glucose sugars) sourced from the cells walls of oats, baker's yeast, mushrooms, and seaweed. It's a rare ingredient that pulls double-duty as a heavy-duty hydrator and skin-soothing repair agent. On the surface, it acts as a humectant that holds water in place and reduces moisture loss for a plumper, smoother feel, while its anti-inflammatory and antioxidant properties make it a great pick for calming redness or sensitive skin The more interesting story is underneath: Despite its large molecular size, oat beta-glucan has been shown to penetrate the epidermis and reach the dermis by slipping between skin cells. Here, it interacts with fibroblasts and macrophages to nudge collagen synthesis and support wound repair. A small 2005 split-face clinical study of 27 subjects found topical beta-glucan produced measurable reductions in wrinkle depth, height, and roughness after 8 weeks of use. It is worth noting the trial was small and the penetration testing used frozen, irradiated skin so the anti-aging data is encouraging rather than definitive. This ingredient gets along with pretty much everything and is typically used around 0.1-1%. Fungal acne: This ingredient is not a food source for the Malassezia yeast because it is a glucose polysaccharide with no fatty acid or ester component. 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 pa
