Primer is often used to fill minor wrinkles and bumps to produce a smoother surface. You can wear both primer and foundation, or foundation on its own, but you wouldn’t wear just primer.
Moreover, do you need primer with foundation?
If your foundation is sitting well on top of your skin, you don’t need a primer. However, if you have oily skin or big pores, you can use a mattifying primer to help smooth out the skin. If you have dry skin, you can use a hydrating primer.
Also to know is, can I use primer everyday?
Yes you can, but its a waste of the product as it is mainly used as a base, go for maybe a bb/cc cream on top of the primer to not let it go to waste.
