While vitamin C is lauded for its ability to boost the immune system, this potent antioxidant works wonders for the skin. Vitamin C helps to repair damage from UV exposure, pollution, and other environmental stressors and can also help to reduce inflammation and redness. With that said, it can cause irritation in high concentrations. The good news is that our BioLumin-C Vitamin C products focus on stability over concentration. Vitamin C is highly unstable and must be tamed to stay active when it's on our skin. Our BioLumin-C formulas contain an ultra-stable Vitamin C complex that's also bioavailable, meaning it's able to get deep into the skin for maximum results.
