Concealer, foundation?

uhhh i dont mean to be stupid but i guess i am but i dunno what the diffrence is between them can you help me :]Concealer, foundation?
Foundation is an all over base make up. Concealer is usually smaller, because it is concentrated. Concealer has more coverage, so for people with dark circles, acne, or symptoms such as rosacea where there is lots of redness, the concealer will more effectively conceal the problem. Foundation is lighter and mostly blends to even out your complexion and provide a base for the rest of your make-up. You generally dot on concealer only on the areas that need the most coverage, whereas foundation is blended all over your face.Concealer, foundation?
Concealer is the stuff you wanna use to cover blemishes, dark circles, etc. Foundation is the stuff you can put all over your face.
Concealer is much more pigmented/intense. It's used to cover up scars/acne/marks/etc. on your face. Foundation is used all over your face, to give you an even skin tone.





Hope that helps. (:
