CONCEALER

You can put concealer anywhere you need to conceal, cover, and neutralize. You can also use concealer to brighten and highlight the complexion. To brighten and highlight with concealer, apply concealer under the eyes, plus where light would naturally hit the face, like the center of the forehead, bridge of the nose, chin, and slightly above the cheekbones for a brightened, lifted look.

If you want to conceal blemishes and cover up discoloration and pores, apply concealer before foundation.
If you want to brighten and highlight the complexion, use concealer after foundation.

Yes, you can wear concealer alone without foundation. Just be sure to blend it out thoroughly to prevent any harsh lines or uneven, patchy areas.

To do this, use Urban Decay’s Virtual Makeup Try-On Tool that analyzes your skin tone and undertone to match you with your perfect concealer shade online.

Yes, you can use concealer without primer. Although, using a primer before concealer can help create a smooth, even surface while also helping to grip the concealer for a brighter look and longer wear.
