The name and the form
Vitamin C is used in skincare in several forms. The supplier names vitamin C in its formula highlights. Those highlights do not establish the exact form or percentage, so we do not invent either.
How we describe the formula
An ingredient associated with skincare research does not automatically transfer those results to every product that contains it. Buttr does not claim a proven collagen increase or a measured cellulite reduction without finished-product evidence.
Use and skin comfort
Follow the product directions, patch test and avoid irritated or broken skin. Do not layer several new active products on the same area at once. Stop use if your skin becomes uncomfortable.
