Make Sure Your Primer Complements Your Foundation. If you wonder why makeup seems to have a mind of its own, chances are you are using the wrong primer for your skin. Primers come in different formulas and finishes. If you have oily and combination skin, a mattifying formula is great to control the shine, while an illuminating primer is suitable for dull skin. Those with spots and blemishes on their face should use a color-correcting primer. Silicone primer makes for a fantastic option to get an even, smooth texture. Whether oil or water, whatever the formula be, your primer and foundation should share the same base; otherwise, they will repel each other or just slide off your face, making it difficult to blend. A good start guarantees a good finishing, so ensure to effortlessly blend the primer and foundation for a clean and subtle look.
