Sarah Chapman C1 Vitamin C Power 1 Serum

One of the most effective skincare antioxidants, vitamin C is loved for its brightening and refining benefits, and Sarah Chapman’s C1 Vitamin C Power 1 Serum offers a moderate-strength formula for noticeable results. It contains two forms of the ingredient – one oil-soluble and one water-soluble – to brighten dark spots and boost collagen production, while egt amino acid bolsters its activity by ‘recycling’ it for even more protection.
