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.
