award-winning daily antioxidant serum. Rather than relying on vitamin C alone, it delivers \u003cstrong\u003e19 antioxidants\u003c\/strong\u003e: vitamins C and E, Coenzyme Q10 and 17 additional environmental free-radical fighters, including polyphenol-rich acai, turmeric, cocoa, green tea, grape seed and olive extracts, coffee seed extract, saffron, superoxide dismutase and ergothioneine. An \u003cstrong\u003eanti-pollution complex\u003c\/strong\u003e helps defend against particulate matter, and a \u003cstrong\u003eskin-soothing blend\u003c\/strong\u003e with licorice extract and palmitoyl tripeptide-1 improves the appearance of redness and uneven tone. It is available in 30 ml ($175) and 50 ml ($240), is dermatologist tested, non-comedogenic, and formulated without parabens, fragrance or dyes.\u003c\/p\u003e\n\u003cdiv class=\"auth\"\u003e\n\u003cdiv class=\"mark\"\u003eUS\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong class=\"hd\"\u003ePreferred Authorized skinbetter science US Retailer\u003c\/strong\u003e\u003cp\u003eSourced direct through official skinbetter science channels: guaranteed authentic, batch-fresh, fast US shipping.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"duo\"\u003e\n\u003cdiv\u003e\n\u003ch4\u003eThe problem\u003c\/h4\u003e\n\u003cp\u003eMost antioxidant serums are a vitamin C serum with a little vitamin E added. Skin is not attacked by one kind of free radical, and it is not attacked only by ultraviolet light. Ozone, pollution particulates, blue light and cigarette smoke each generate different oxidative damage, and a single-antioxidant formula leaves most of that unaddressed.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch4\u003eNineteen Antioxidants, Because One Is Not Enough\u003c\/h4\u003e\n\u003cp\u003eAlto Defense Serum is built as comprehensive antioxidant protection: water-soluble, enzymatic and lipid-soluble antioxidants working together across 19 ingredients, so the different classes of oxidative stress are covered rather than just one. The formula has been studied against ozone-induced damage in a reconstructed human skin model (\u003cem\u003eArchives of Dermatological Research\u003c\/em\u003e, 2021) and against blue light and cigarette smoke in human skin tissue (\u003cem\u003eJournal of Cosmetic Dermatology\u003c\/em\u003e, 2021), with antioxidant capacity characterized in the \u003cem\u003eJournal of Clinical and Aesthetic Dermatology\u003c\/em\u003e, 2019.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"skinbetter science","offers":[{"title":"50 ml","offer_id":46549397831830,"sku":"SA090800","price":240.0,"currency_code":"USD","in_stock":true},{"title":"30 ml","offer_id":46549397864598,"sku":"SA090700","price":175.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0660\/6225\/4230\/files\/skinbetter_science_Alto_Defense_Serum_30mL_1.png?v=1789832054","url":"https:\/\/skincrew.com\/products\/skinbetter-science-alto-defense-serum","provider":"SkinCrew","version":"1.0","type":"link"}
