This one is for the ladies, and some men too. 
Do you ever notice how your perfectly blended concealer looks not-quite-so-perfect somewhere else?
No, you’re not crazy. Its all to do with lighting.
Some people even avoid certain types of lighting because they know their make-up always looks worse under those types of lights.
But you don’t have to do this.
The trick is to apply your make-up under natural light.
Think of sunlight as the ultimate benchmark.
If your makeup looks good under natural light, it’ll look good under any type of artificial lighting.
A nice side effect of this is that when you use natural light, you’ll find yourself applying less concealer, foundation, blush etc. etc. This is because you’re able to blend it much more efficiently than ever before.
