Rimmel Multi-Tasker All Day Grip & Breathable Primer is formulated with a combination of active ingredients designed to enhance makeup application and longevity. The primer contains polyacrylic acid, which acts as a film-forming agent to create a smooth surface for makeup application. This ingredient also helps to improve the adherence of makeup to the skin, extending its wear time. Additionally, the primer contains ethylhexylglycerin, a skin-conditioning agent that helps to hydrate and soften the skin. This ingredient is known for its moisturizing properties, which can help to improve the overall appearance and texture of the skin. Furthermore, the RIMMEL primer contains silica, a mineral that helps to absorb excess oil and reduce shine on the skin. This can help to create a matte finish and prevent makeup from sliding or creasing throughout the day. Silica also gives the primer a smooth and lightweight texture, making it easy to apply and blend onto the skin. The pH of the RIMMEL primer is formulated to be compatible with the skin's natural pH levels, reducing the risk of irritation or allergic reactions. The viscosity of the primer is designed to be easily spreadable and absorbed into the skin, providing a breathable and comfortable wear throughout the day.
