Ingredients higher up in an ingredient list are typically present in a larger amount. Ascorbyl Glucoside (AA-2G) is one of the most stable vitamin C derivatives out there. It's made by attaching a glucose molecule to ascorbic acid; this glucose "cap" shields the vitamin C from air, light, heat, and metal ions that normally cause pure ascorbic acid to oxidize. Once on your skin, the enzyme alpha-glucosidase snips off the glucose and gradually releases active ascorbic acid right where it's needed. Basically, it behaves like a slow-release pro-vitamin C with less of a stinging that high-strength ascorbic acid can cause. The research supports the classic vitamin C benefits as well. In lab and human studies, AA-2G slowed down the skin's production of melanin (the pigment behind dark spots) and helped shield skin cells against sun damage better than ascorbyl phosphate. These studies also showed AA-2G released vitamin C over a longer period. A frequently cited manufacturer trial found that a 2% AA-2G face cream significantly improved wrinkle depth and skin roughness after 45 days. And in 2009, a clinical trial showed it meaningfully lightened dark patches on the gums compared to a placebo. There's also collagen-synthesis support (since vitamin C is a required cofactor for that) and an antioxidant effect too. Typical usage is usually between 0.5-5% and most studies/products land around 2%. AA-2G performs best when formulated at a mildly acidic pH (~5-7) which is much gentler than the pH that pure vitamin C demands (~2.5-3.5). Just one thing worth knowing: the in-skin conversation rate is only about 55-60% by weight. So a 5% AA-2G product delivers roughly 2.75-3% of actual active vitamin C. On top of that, skin absorption is relatively low because the ingredient is water-soluble. C9-12 Alkane is synethically created using alkanes, or paraffins. It is added to products as a solvent. This means its main purpose is to help dissolve ingredients and create even texture. Coco-Caprylate/Caprate is a lightweight ester created from coconut oil fatty acids, caprylic acid, and capric acid. It is an emollient that helps soften skin and reduce transepidermal water loss (TEWL). What sets it apart from heavier emollients is its ultralight, non-greasy feel. Once applied, this ingredient dries down quickly and leaves a dry, silky finish behind. This also helps improve spreadability and texture. This ingredient has an excellent safety-record and is non-irritating. Typical concentrations for cosmetics range from 0.5-62%. Research on Malassezia growth found no growth on fatty acid esters with chain lengths shorter than 12 carbons (it prefers C11-24). Since Coco-Caprylate/Caprate is built on C8 and C10 fatty acids, it is out of the range that Malassezia metabolizes, and therefore safe for fungal acne. Glutathione is a tiny protein-like molecule (a "tripeptide" build from 3 amino acids: glycine, cysteine, and glutamic acid) that yo
