What is the function of a concealer in makeup application?

The function of a concealer in makeup application primarily revolves around its ability to cover specific areas of the face that need extra attention. Concealers are typically thicker than foundation and are designed to conceal imperfections such as dark circles, blemishes, redness, or scars. By providing targeted coverage, concealers help create a smoother, more even complexion, allowing the foundation to be applied seamlessly over the entire face without these imperfections showing through.

This specific focus on coverage differentiates the role of a concealer from other makeup products. While some products might aim to highlight or add color, a concealer's primary purpose is to provide concealment, ensuring that those areas blend well into the surrounding skin tone for a polished look.
