What if adding more concealer is actually making your makeup look worse? A heavy layer may initially hide dark circles, but as you move, blink and smile, excess product can collect in fine lines. The smoother approach starts before the concealer touches your skin. Hydrate the area, use a small amount of product, blend carefully and set only where necessary. Once you understand where concealer belongs and how much you really need, getting a clean, skin-like finish becomes much easier.
