If you're constantly switching up your foundation, there's probably a good reason why. But, once you've found the perfect type of coverage, you're likely never to switch again. To help you find the right type of foundation, we enlisted the pros at NYX who gave us 6 common misdemeanors customers often make when shopping for the right type of coverage. 

1. ALREADY WEARING FOUNDATION
Oftentimes customers don’t want to leave their house without foundation on. But, when the time comes to test it out they either try it on top of foundation or dab coverage only in one area of the body, which can make you choose an inaccurate shade. 

2. NOT UNDERSTANDING YOUR SKIN TYPE
Customers tend to buy foundations based on trends (matte, dewy, etc.) but barely ever keep in mind that every skin is different and what might work for someone, may not work on you. If you do not know what skin type you are (whether you are dry, oily, combination or even dehydrated) chances are you won’t find the right foundation. 

3. KNOW YOUR UNDERTONE
A lot of people don’t know whether they have a warm, neutral or cool undertone. If you’re warm and opt for an alabaster shade, your skin will end up looking ashy. The same rule applies to those who have a cool undertone and want darker coverage, which can make you look orange. Don't know what undertone you have? Here's our quick tip: if you happen to be in between shades you’re in the neutral group. You can either be neutral cool or neutral warm depending on the colour of your veins. Look on the inner wrist area, or forearm, and see what colour your veins are. If your veins look more green, you’re more warm. If your veins look blue, you’re more cool.

4. GET LIT
Proper lighting is key when looking for the right foundation match. The best way to do so is under natural light, with no makeup on. You'd be surprised how different your makeup looks in natural light looks compared to indoor lighting. 

5. SWATCH IT 
Swatching in the right areas of your body is key for finding a perfect match. Pick 3 different spots (we suggest the forehead, chin/jaw and décolletage) and always look at your overall skin tone. Lots of people swatch on the neck and don’t realize that necks on the case of lighter skin tones, barely ever take any sun so they end up picking a colour that’s too light. 

6. WATCH OUT FOR OXIDIZATION 
Just like fruit, some foundation formulas can turn a shade or two darker when exposed to air. To combat this problem, spot test on various areas and wait a few minutes to see how much the formula oxidizes before blending it all over your skin. While using your fingers is a good way to see how foundation blends, using a beauty blender may be the way to go.
