To start, choose a concealer shade that matches your foundation or is one shade lighter. For best results, we recommend applying concealer after applying your foundation. Use Double Wear Concealer with Concealer Brush 5. Swipe concealer to back of hand, then with brush smooth on over desired area. Blend well. Targeted concealing techniques: For darkness around eyes, go with a slightly lighter shade than your foundation. For puffiness, slightly darker. For uneven skin tone, wear the same exact shade as your foundation.
