Rinse it off with cold water afterwards (cold water helps to close pores, so that your makeup doesn't enter your skin). Pat your face dry with a clean towel.
A moisturizer with SPF over 15 can be your best bet during the summer. If you have fairly even skin or if you don't want to use foundation, use a tinted moisturizer to cover up light blemishes. An oil based moisturizer is best during winter for people with dry skin. Whereas, people with oily, acne prone skin should go for water based moisturizers.
If you have only slight unevenness in your skin tone, mix a bit of concealer and moisturizer and apply it evenly all over your face. Larger blemishes can be covered with a base foundation.
The concealer should be used to cover dark circles under eyes and puffy under-eyes. Use a cream-based concealer as it does not accumulate in the creases of the eyes. You may highlight your cheekbones with a rosy or peach cream blush.
Simply applying lipstick makes you look put-together. It is of utmost importance to make your lips look healthy and plump.
You are free to make necessary changes to the aforementioned routine to suit your requirements. Along with a makeup routine, it is equally important to have a daily skin care routine to enhance the natural beauty of your skin.
