I have tried many types of primers from different brands and in this list I will share what worked for me. There is a variety for different kinds of skin type so I hope this can actually help you find the primer that will secure your makeup in the heat! Think of primer as the foundation for your foundation. It solves common complexion issues and acts as a barrier so your skincare and makeup don't mix and cause patchiness! Plus, it creates a smooth barrier between your skin and makeup, helping your foundation glide on flawlessly, controlling oil, minimizing pores, and extending the life of your makeup.
