Ingredients higher up in an ingredient list are typically present in a larger amount. Alanine is an amino acid and is already found in the human body. Our skin uses alanine to build collagen, elastin, and keratin. 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). Ethylhexylglycerin is created from glycerin. It is a multitasker ingredient that: The CIR Expert Panel found minimal skin absorption or sensitization of any kind in a safety assessment. Though this ingredient is considered well-tolerated, a small number of cases of allergic dermatitis have been published since 2002. Just be sure to patch test if you are unsure. Industry-reported use ranges from 8% in rinse-off products and 2% in leave-on formulations. Glutamic Acid is an amino acid that is found in all living organisms. Our bodies use this to help nerve cells in the brain communicate with other cells. In cosmetics, glutamic acid is a famous humectant. It draws water from the air to your skin, keeping your skin hydrated (like hyaluronic acid). An in-vitro study from 2024 found glutamic acid to play a role in inhibiting inflammation and thus a potential skin-soothing ingredient. Other studies show it to be have potential wound healing, skin barrier repair, and hair growth properties. Glutamic acid has poor solubility in water and other solvents. Glycoproteins are proteins with sugar chains attached to them. They're naturally found throughout your body, including your skin's extracellular matrix. In your skin, glycoproteins work alongside collagen and other structural proteins to keep everything held together and functioning properly. Their sugar components make them great at binding water and keeping the skin hydrated. They also part of the extracellular matrix that plays a direct role in wound healing. The glycoproteins found in skincare are most commonly derived from yeast, algae, or plant sources. In-vitro studies have shown that yeast-derived glycoproteins can boost cellular oxygen content and increase energy production in skin cells. In general, this is a well-tolerated humectant and skin conditioning ingredient. The Cosmetic Ingredient Review (CIR) Expert Panel has found no signs of irritation, adverse effects, or abnormal reactions from this ingredient. Palmitoyl Tetrapeptide-7 (formerly Palmitoyl Tetrapeptide-3) is a synthetic peptide. Its main job is to fight what researchers call "inflammaging". "Inflammaging" is the slow, low-grade chronic inflammation that quietly breaks down collagen as we age. This ingredient calms down a specific inflammation signal in your skin cells (called IL-6). When left unchecked, this signal triggers
