Formulated for oily and acne-prone skin, the numbuzin No.1 Serum features pantothenic acid (vitamin B5) and niacinamide as its key active ingredients. The pantothenic B5 complex works to calm irritation and support the skin’s natural moisture barrier, while niacinamide helps regulate excess sebum production and reduce the occurrence of breakouts. This serum is designed to deliver soothing hydration without adding greasiness, making it suitable for skin that is prone to congestion and shine.

The lightweight, water-like texture absorbs rapidly into the skin, leaving a non-sticky finish that does not clog pores. By combining the hydrating properties of pantothenic acid with the oil-controlling benefits of niacinamide, the formula aims to balance the skin’s condition without disrupting its natural pH. Its gentle composition excludes common irritants, allowing it to fit into daily skincare routines for consistent use.

This product comes in a 1.69 fl. oz. bottle and is appropriate for those seeking a simple, effective step to calm sensitivity, refine texture, and maintain a matte appearance throughout the day. The focus is on providing a functional base for the skin barrier while addressing the dual concerns of excess oil and occasional blemishes. No exaggerated claims are made; instead, the formulation is presented as a straightforward option for supporting a clearer, more comfortable complexion.
