On ’Til Dawn Big & Bitty Mattifying Waterproof Setting Spray Duo is a two-piece set offering a full-size bottle (3.4 fl. oz / 146 mL) and a travel-size bottle (1.0 fl. oz / 46 mL). The spray is formulated to help set makeup while controlling shine and resisting moisture, making it suitable for those seeking a long-lasting, matte finish. Its lightweight, water-based formula is designed to be applied after makeup application to lock in the look without adding heaviness or stickiness.

The mattifying properties of this setting spray come from ingredients that help absorb excess oil and reduce visible shine throughout the day. The waterproof aspect supports wear in humid conditions or during activities where perspiration may occur, contributing to the stability of makeup over extended periods. This product is typically recommended for normal to oily skin types, as the matte effect can help minimize the need for frequent touch-ups.

The duo format provides practicality for different routines. The full-size bottle is suitable for daily use at home, while the travel-size bottle meets carry-on restrictions and allows for easy portability during trips or commutes. The spray nozzle delivers a fine mist that covers the face evenly without disturbing underlying makeup. Application is straightforward: hold the bottle at arm’s length, close eyes, and mist over the face two to three times, then allow to air dry.

Packaged in a plain yet functional design, the On ’Til Dawn Big & Bitty Setting Spray Duo offers a no-frills approach to makeup longevity. It does not claim to alter skin texture or provide skincare benefits beyond setting. Users with sensitive skin may wish to patch test due to the presence of common setting spray ingredients such as alcohol or fragrance, though specifics vary by batch. Overall, this product serves as a reliable option for those wanting a matte, waterproof hold in a convenient two-size bundle without added marketing hype.
