An antioxidant serum that helps neutralize environmental stressors while brightening and supporting firmness.
This serum is a powerhouse when it comes to brightening and protecting skin. It delivers all the glow and firming benefits of vitamin C without the sting or instability you sometimes get from other formulas. We love how it layers seamlessly under SPF, boosting protection and giving skin a radiant, healthy finish. It’s a daily must-have for defense against both aging and environmental stress.
Alastin C-RADICAL Defense Antioxidant Serum is a next-generation vitamin C formula designed to brighten, protect, and repair skin. Unlike traditional vitamin C serums that can destabilize or irritate, this advanced formula combines 15% L-ascorbic acid with Alastin’s proprietary PATH-3 Technology to neutralize free radicals, defend against environmental stressors, and support the skin’s natural ability to produce new collagen and elastin. Niacinamide, green tea, and a blend of powerful antioxidants provide additional brightening, anti-aging, and calming benefits. The lightweight, fast-absorbing texture makes it easy to layer under sunscreen or moisturizer, leaving skin radiant, firmer, and more resilient.
Apply to clean skin before moisturizer and SPF; pair with nightly retinol for synergy. Allow a full minute for absorption before the next step. Use morning and evening when possible, and pair daytime routines with SPF. Treat this as a small daily ritual—slow the breath, soften the jaw, and let the skin receive.
