What is the purpose of a toner in skincare?

1. To balance the skin's pH

2. To remove makeup

3. To moisturize deeply

4. To provide sun protection

The correct answer is: To balance the skin's pH

The purpose of a toner in skincare is primarily to balance the skin's pH. After cleansing, skin can become slightly acidic or alkaline, depending on the cleanser used. Toners are formulated to restore the skin’s natural pH balance, which is essential for maintaining its overall health and function. This balanced state helps to prepare the skin to absorb the following products more effectively, such as serums and moisturizers. Additionally, toners can also provide other benefits like tightening pores, smoothing skin texture, and providing an initial layer of hydration. However, their main function remains centered on pH balance, making them an important step in a comprehensive skincare routine. Other options like removing makeup or providing sun protection are typically addressed by specific products designed for those purposes, rather than a toner’s primary role.
