Q: Is this serum suitable for sensitive or oily skin?

A: Absolutely. The lightweight essence texture absorbs quickly without clogging pores, making it compatible with all skin types — including sensitive, oily, dry, and combination skin. Niacinamide is especially beneficial for oily skin types as it helps manage the appearance of pores.
