Makeup primer is a cream, gel, or powder applied to the skin before makeup to create a smooth canvas, improve makeup coverage, and extend makeup wear. Most primers contain silicone-based polymers, which help fill in imperfections in the skin such as lines, wrinkles, and pores. Some primers are made with ingredients that can also help treat specific skin conditions and issues, like dryness, oiliness, blemishes, or the early signs of aging. Primers come in different forms, including silicone-based, moisturizers, sprays, and more. Different types of primers include:

• Pore filling primers: These primers are designed to fill in pores and create a smooth surface for makeup application.

• Mattifying primers: These primers are ideal for those with oily skin as they help control excess oil and keep skin looking matte.

• Illuminating or dewy primers: These primers add a glow to the skin and are ideal for those with dry skin.

• Color correcting primers: These primers are designed to correct skin discoloration and even out skin tone.

When choosing a primer, it is important to identify your skin type and what you are looking to get out of a primer in order to choose the right type for you. It is also important to check the label for any chemicals or ingredients that you might be sensitive to. Some primers contain harsh, irritating ingredients or strange chemicals that could be dangerous for your skin.
