Ingredients higher up in an ingredient list are typically present in a larger amount. 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. Caprylyl Glycol is a humectant, skin conditioner, emollient, and preservative booster derived from either caprylic acid or synthetically created. Typical use levels vary from 0.3-1% as a preservative booster and go up to 2% to condition skin. Because it is not a free-fatty acid, this ingredient is fungal acne safe (there's nothing for Malassezia to feed on). This peptide is the copper salt and formed by reacting palmitic acid and heptapeptide-14. This uses a high-tech delivery system called The Cosmetic Drone, where the peptide is enclosed in a shell made from Lactic Acid/Glycolic Acid Copolymer and Polyvinyl Alcohol. Another peptide on the outside guides the capsule to fibroblast cells, the collagen-producing cells in the skin. Once it reaches the fibroblasts, Copper Palmitoyl Heptapeptide-14 boosts the production of collagen and elastin. This advanced system works at an incredibly low concentration of just 0.001%. 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. Heptapeptide-15 Palmitate is a synthetic targeting peptide. It's made up of seven amino acids with a palmitic acid tail attached. This fatty acid attachment increases the molecule's hydrophobicity, improves stability, reduces enzyme degradation, and enhances its ability to cross the skin's lipid barrier (this is a common challenge for peptides). As a targeting peptide, it sits on the outer shell of an encapsulated ingredient system and seeks out receptors on collagen and elastin producing cells in skin. Once it binds, the cell internalizes the capsule and releases the active payload inside; it essentially acts as a GPS guiding ingredients to th
