PURESHINE METHOD is a science-driven vitamin C serum formulated with 15% pure L-ascorbic acid and complementary antioxidants to support radian, healthy-looking skin.
Pure L-ascorbic acid is highly effective but notoriously unstable. Concentration, pH, and formulation all matter when creating a vitamin C serum designed to remain effective and fresh.
Formulated with 15% L-Ascorbic Acid, Vitamin E, and ferulic acid, PURESHINE METHOD provides antioxidant support against environmental stress while supporting collagen production and a more even, radiant-looking complexion.
Created by a chemistry educator with a background in toxicology, PURESHINE METHOD reflects a science-first approach to skincare—focused on purposeful ingredients, thoughtful formulation, and the science behind why they work.

FAQs
When should I use this serum? Use once daily in the morning on clean, dry skin. Always follow with sunscreen.
Can I use this with other active ingredients? Yes. This serum pairs well with hydrating and barrier-supporting products. If using multiple actives, apply vitamin C first and introduce new products gradually.
Is this safe for sensitive skin? This formula contains pure L-ascorbic acid, which may cause mild tingling upon application. We recommend a patch test before first use, especially for sensitive skin.
Why does vitamin C sometimes tingle? L-ascorbic acid works at an acidic pH to remain active and effective. A brief tingling sensation is normal and typically subsides quickly.
How long will one bottle last? With regular use 2-3 drops daily, one bottle lasts approximately 6-8 weeks.
