How to apply makeup primer is a simple yet essential step in creating a flawless makeup look. Start with clean, moisturized skin to ensure the primer glides on smoothly. Squeeze a small amount of primer onto your fingertips or the back of your hand. Using your fingertips or a soft makeup sponge, gently apply the primer to the center of your face and blend it outward. Focus on areas where makeup tends to fade or settle into fine lines, such as the T-zone, around the nose, and the chin. Work the product into the skin using light, circular motions or soft tapping, making sure to create an even, thin layer. Allow the primer to set for a minute or two before moving on to foundation or other makeup products.
