Skincare, hydration, and nutrition are crucial, remember you can work hard on covering but the main goal should be to eliminate or reduce your Dark Circles as well.

Eye creams that have caffeine are great to improve the look of dark circles. Some of my favorites: 

• Fast response eye cream de MAC  - A classic staple in my kit. I have been working with it since I started as a Makeup Artist. 
• First Aid Beauty Has a wide range of Eye Creams. Their texture is very enjoyable and all of their products are natural and very effective. My  faves are:
  • First Aid Beauty Eye Duty Triple Remedy, Fair/Medium
  • Detox eye-roller 
• Ole Henriksen banana bright bright eye cream. Is nourishing and brightening
• Sheet masks are great to deliver effective skincare. I Love the Glam black lace hydrogel mask from biobelle it's made out of Black Tea extract full of antioxidants and caffeine.

Choosing the right concealer is also very important. It needs to be the same tone as our skin and not lighter than our dark circles so it could cover them. In most cases, peach undertones are better to neutralize the color. 

My little secret is that I use a liquid highlighter in peach tones before the concealer. The light and the color will help me conceal the darkness so covering would be easier. I use mostly the S/B highlighter 0054 from Temptu, even though it is for use with the airbrush you could use it with a sponge and get beautiful results.

The most important tip is to use very thin layers of product and especially concealer to avoid creases. I like to pat in with sponge so it would look smooth. If it looks too thick then you can blend it with a little eye cream.
