Common Questions

What is Concentration and Formulation?

Why concentration and formulation matter more than the ingredient name alone.

Concentration

The amount of an active ingredient matters. Too little may be ineffective; too much may cause irritation. Retinol products, for example, range from 0.01% to 1%. Starting low and building gradually minimizes irritation while maintaining effectiveness.

pH and Delivery

Some actives, like AHAs and vitamin C, require specific pH ranges to be effective. Formulation also affects how deeply ingredients penetrate. Stabilization and delivery systems can enhance effectiveness but are often not visible on labels.
