The Elf Putty Primer Brush & Applicator is a cosmetic tool designed with specific chemical composition to enhance the effectiveness of primer application. The brush consists of nylon bristles made with polypropylene handles for durability and ease of use. The Elf Putty Primer Brush & Applicator contains active ingredients such as dimethicone, silica, and cyclopentasiloxane. Dimethicone is a silicone-based polymer that acts as an emollient and provides a silky smooth texture when applied to the skin. Silica is a mineral that helps to absorb excess oil and create a matte finish on the skin. Cyclopentasiloxane is a volatile silicone that helps to improve the spreadability of the primer. The combination of these ingredients in the Elf Putty Primer Brush & Applicator works synergistically to create a smooth and even base for makeup application. Dimethicone helps to fill in fine lines and pores, while silica mattifies the skin and cyclopentasiloxane ensures a lightweight feel upon application. With a neutral pH and moderate viscosity, the Elf Putty Primer Brush & Applicator is suitable for all skin types. The ingredients in the primer have been carefully selected to ensure optimal absorption and bioavailability on the skin, enhancing the longevity and wear of makeup applied on top.
