Vichy Liftactiv Peptide-C Sunscreen SPF 30 Versus Vichy Liftactiv Peptide-C

Vichy Liftactiv Peptide-C Sunscreen SPF 30 Versus Vichy Liftactiv Peptide-C Detailed comparison of Vichy Liftactiv Peptide-C Sunscreen SPF 30 versus Vichy Liftactiv Peptide-C. This chemical sunscreen covers most of the UV range, lighter on the deep UVA that drives aging. This anti-aging moisturizer is formulated around Adenosine and Ascorbyl Glucoside to soften the look of wrinkles and brighten dull-looking skin.

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. 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). Cyclodextrins are ring-shaped sugar molecules made from starch. It is used to stabilize, protect, and slowly release active ingredients. This ingredient can help prevent oxidation, reduce irritation from strong actives, and make certain ingredients absorb better once applied. Once applied to your skin, enzymes gradually break down the cyclodextrin "ring"; this releases the active ingredient in a controlled way. Dimethicone is a type of synthetic silicone created from natural materials such as quartz. It is also known as polydimethylsiloxane. What it does: Dimethicone comes in different viscosities: Depending on the viscosity, dimethicone has different properties. Ingredients lists don't always show which type is used, so we recommend reaching out to the brand if you have questions
