While it's not always necessary to use a primer before applying foundation, it can be helpful in achieving a flawless finish and making your makeup last longer. Here are some of the benefits of using a primer:
Smoother application: Primers help to create a smooth base for your foundation, making it easier to apply and blend.
Pore minimizing: Some primers can help to minimize the appearance of pores, giving your skin a smoother, more even look.
Long-lasting: Primers can help to extend the wear time of your foundation, keeping your makeup looking fresh all day.
Oil control: If you have oily skin, a primer can help to control excess oil and prevent your foundation from sliding off.
Hydration: Some primers contain hydrating ingredients that can help to keep your skin moisturized throughout the day.
Overall, while it's not strictly necessary to use a primer before foundation, it can definitely help to improve the look and longevity of your makeup.
