Elizabeth Arden To use liquid concealer, start by prepping your skin with cleansing and moisturizing. Choose a shade that matches your skin tone or is one shade lighter, and apply a small amount to the area you want to cover using a brush or your fingertips. Blend the concealer thoroughly for a natural finish. Finally, continue with the rest of your makeup application as usual. Remember to blend well and have fun experimenting with different techniques, such as using the concealer as a highlighter. Concealers & Correctors
