Not Prepping the Undereye
When it comes to the order in which you should apply your makeup, there are numerous debates. Traditionalists will argue that you should start with the foundation and work your way up. Others, however, will argue that you should start with the eyes so you can clean up before building your perfect base.
If you decide to begin with your eyes, make sure to prep the area around your undereye as well as the area around your eyelid. After applying serum, you should apply primer.
Powdering the Entire Face
What was once considered normal by those in the know may now be frowned upon. The heavily powdered, matte face that was popular in the 1990s and 2000s is no longer fashionable.
Glossy or dewy skin is increasingly popular, and everyone is obsessed with highlighter at the moment. However, this does not negate the need for powder. Simply apply it to your T-zone and other oily areas.
