I am not a big believer in concealer since I feel like it's application can be tricky, I usually refrain form using it unless strictly necessary. Not applied well concealer can take a life of its own and instead of fixing the problem it might cause it to stand out more, or aggravate it.
The perfect Concealer would have natural coverage concealer that instantly eliminate tell-tale signs of stress and fatigue. Provides complete, natural-looking coverage, evens skin tone, covers dark circles and minimizes fine lines around the eyes.
That said I have tested and searched high and low for the perfect Concealer. My search for the perfect Concealer brought me to Lancôme Effacernes Waterproof Undereye Concealer.
The Vitamin A and skin conditioning ingredients gives it a smooth texture, easy application and blendability, a matte finish that does not cake or crack, and best part of it all...it's waterproof and that makes it extremely long lasting! Another point in favor to Effacernes is that unlike most eye concealers that are available in a basic yellow tone, it comes in nine different shades ranging in tones from Porcelain to Bronze.
I love this product! I have added it to my professional makeup kit and my own personal one!
