About Alto Defense Serum Plus

Alto Defense Serum Plus delivers advanced antioxidant protection through a potent blend of 17 powerful antioxidants, including stabilized vitamin C, vitamin E, and resveratrol. This clinical-grade serum is formulated with SkinBetter Science's proprietary antioxidant complex that helps neutralize free radicals from UV exposure, pollution, and blue light while supporting skin's natural repair processes. The lightweight, fast-absorbing formula also contains ceramides and niacinamide to strengthen the skin barrier and improve overall skin tone and texture. Unlike traditional vitamin C serums that can be unstable or irritating, this advanced formulation is designed for daily use and provides visible improvements in skin brightness, firmness, and clarity over time. Ideal for patients seeking comprehensive environmental protection and anti-aging benefits without the irritation often associated with high-concentration vitamin C products.
