What is the primary benefit of using a toner in skincare?

The primary benefit of using a toner in skincare is to balance pH levels. After cleansing, the skin's natural pH can be disrupted, often becoming more alkaline. This can lead to issues like dryness and irritation. Using a toner helps to restore the skin's acidity, which is essential for the overall health and function of the skin. A balanced pH can enhance the skin's barrier function, reduce inflammation, and improve the absorption of subsequent skincare products.

Additionally, while toners can have hydrating properties and sometimes include ingredients that help with exfoliation or makeup removal, these are not their main purpose. The core function of toners aligns most closely with the restoration of pH balance, making it a critical step, especially for those who want to maintain a healthy complexion following cleansing.
