Alastin C-RADICAL Defense Antioxidant Serum represents a fundamentally different approach to Vitamin C skincare — combining a novel, highly stable form of Vitamin C with 14 additional vital antioxidants in a single serum, delivering radically broader environmental protection than any single-antioxidant Vitamin C product can achieve. The 'C-RADICAL' name reflects the serum's core mission: neutralizing the free radicals generated by the full spectrum of environmental stressors that degrade skin quality daily.The novel Vitamin C form provides potent antioxidant and brightening activity with superior stability — resisting the oxidation and discoloration that makes standard L-Ascorbic Acid serums degrade rapidly. The 14-antioxidant complex is specifically assembled to address the different types of free radicals generated by UV radiation, infrared rays, blue light, air pollution, and metabolic processes — each antioxidant targeting a different radical species or pathway for comprehensive coverage. Silver Mushroom (Tremella Fuciformis) provides intense hydration. Hydroxymethoxyphenyl Decanone supports natural hyaluronic acid production. Niacinamide improves barrier function, skin tone uniformity, and sebum balance. The formula helps conserve elastin — a key structural protein that standard antioxidant serums do not specifically target.Apply 1–2 pumps to face and neck in the AM after cleansing and before moisturizer and SPF. Non-comedogenic, hypoallergenic, fragrance-free. Available at Beauty Riche — authorized Alastin retailer with same-day shipping.
