Never rub makeup
Always remember that the under eye area is highly sensitive and thin, and any kind of makeup application in this area needs to be done with a soft hand and an even softer brush. Never rub in any makeup in this area, always glide it on or dust it on using a good quality eye makeup brush.
Don’t cake-up your makeup!
Since the under eye area is gentle and thin, it simply cannot take any kind of cakey makeup or too many layers of it. For example, too much eye shadow or hurried layering application of eye shadow in this area is bound to cause your eye shadow to flake or crease, leaving you with a very unflattering look. The best way to avoid something like this happening is to apply makeup in this area softly with feather like strokes.
