The Witch range do make up, which help get rid of spots while covering them up at the same time. I would suggest using this, as it's not a good idea to cover spots. To start with have clean skin and apply a moisturizer, then apply a primer that helps fight against spots. Apply concealer to your clean finger then dab/tap gently onto affected area. Apply foundation as usual then repeat a layer of concealer and power to seal everything.
Make sure you cleanse skin in the morning and before bed and after exercise and never leave make up on over night.

Spots? Are you referring to acne or freckles?

Try using a Concealer. Its a dense form of regular foundation that is used to cover blemishes, dark spots, under eye circles and other imperfections. Concealers are available in different textures and coverages. I would start off little by little and adding to only the areas that are needed.
