Some common mistakes women make when applying foundation -
Choosing the wrong shade / tone
Remember that foundation should be in the same tone as your natural complexion. To find the perfect tone for your skin apply the tester of the closest colours you choose on your jaw line and finalize on the one that blends most invisibly.
Applying with force
If you rub your sponge or applicator too hard all you will get is the reddening of the skin and an uneven coverage and application of the foundation. It is always better to use your fingertips and apply with light circular motions as they warm up the product and glides on the skin.
Applying with insufficient light
If the room is too bright or too dark you will not be able to see properly and cover all of your face evenly. You will notice your mistakes when you go outside , so it is advisable to put on your makeup in the same light in which you will be wearing it.
Make sure you blend your foundation very well around the hairline, nose, ears, jawline , chin and especially the neck as its the area which is most visible with foundation.
Applying more than required
do not pile the foundation in one area If you are trying to cover up some imperfection because this will attract more attention to the area. Apply in an even layer over your whole face so that the color is unified.
Preparation of skin
You have to clean the skin and hydrate with a good moisturizer prior application of the foundation to avoid the cracks and visible lines.
