In summers, make sure that your skin in moisturized.
Use a toner according to your face.
Those who have oily skin can use oil free toner.
Using a gel/silicone based primer is a must.
Cream based makeup washes off easily with sweat.
Use a waterproof or matte formula to make your makeup last longer.
Don't forget to apply blotting powder after applying makeup to your face and before spraying setting spray.
If you have not used foundation, then blotting paper can also be used in the meantime.
In summer, always use cool shades for makeup.
