Ingredients higher up in an ingredient list are typically present in a larger amount. 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. Hydroxyacetophenone is a small phenolic molecule that earns its place in a formulas as an antioxidant and preservative booster. As a phenol, it is able to neutralize free radicals to protect both the product and the skin from oxidative stress. Though it can't kill microbes on its own, it works as a good supporting agent when combined with other preservatives like Phenoxyethanol or 1,2-Hexanediol. This ingredient naturally occurs as piceol in Norwegian spruce needles (~0.4-1.1% dry weight and in cloudberries). Though the cosmetic-grade material is synthesized for purity and consistency. You'll usually see it used at low levels and suppliers recommend up to 1% added to a water phase. Safety testing was done at concentrations like 0.05% in SPF products and 0.5% in a Human Repeated Insult Patch Test. The safety evidence is assuring; this ingredient is safe for cosmetics in current use and also holds safety status as a food flavoring as well. An honest caveat: the "soothing" and "anti-inflammatory" claims come mostly from supplier marketing rather than published clinical trials. The Cosmetic Ingredient Review's own literature search found no useful efficacy studies on this ingredient. So the antioxidant and preservative-boosting roles are the well supported ones while the calming benefit is plausible but thinly evidenced. Overall, this is a well-tolerated, low-irritation multitasker that quietly helps a formula stay fresh and stable. Sodium Cocoyl Glutamate is a gentle cleanser and surfactant. It is the sodium salt of the Cocoyl Glutamic Acid and comes from coconut oil. As a surfactant, it helps lift dirt and oil to be washed away. Sodium Cocoyl Glutamate also has an emolliating effect and can help leave the skin feeling soft. Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product. So why is it so popula
