Ingredients higher up in an ingredient list are typically present in a larger amount. This peptide is more commonly known as Thymulen 4 BG. It is derived from a youth hormone called thymopoietin. Thymopoietin helps regulate the immune system and decreases naturally with age. According to the manufacturer, this peptide boosts the skin's immune defenses and regenerates the outer layers of skin. Bis(Tripeptide-1) Copper Acetate is a peptide. 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). Dextran is a sugar (polysaccharide) with skin hydrating properties. Fun fact: Louis Pasteur first discovered this ingredient as a microbial product in wine. 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. Myristoyl Nonapeptide-3 is a peptide. Pentylene Glycol (1,2-pentanediol) is a multitasking little diol with three main roles in a formula: Research on alkanediols (the family pentylene glycol belongs to) show they work by disrupting microbial cell membranes. This disruption helps the primary preservative system in a product work more effectively at lower doses. On the safety side, the Cosmetic Ingredient Review Expert Panel has concluded this ingredient to be safe as used in current cosmetic practices + concentrations. Typical use levels in a formula run about 1-5%. Trifluoroacetyl Tripeptide-2 is a peptide. Tripeptide-1, also known as GHK), is a small, three-amino-acid peptide made up of glycine, histidine, and lysine. This ingredient is a signal peptide and tell your skin to start producing fresh collagen, elastin, and other key structural proteins. This helps maintain firmness and reduces the look of fine-lines/wrinkles. GHK is also unique because is also acts as a carrier peptide. It binds to and transports copper ions (forming the complex GHK-Cu)
