What is the purpose of using a toner in a skincare routine?

The purpose of using a toner in a skincare routine is primarily to balance the skin's pH after cleansing. Cleansing can often disturb the skin's natural acid mantle, leading to fluctuations in pH levels. A toner helps restore the skin to its optimal pH, which is crucial for maintaining skin health and function. By rebalancing the pH, toners can help prepare the skin for subsequent steps in the skincare regimen, such as serums and moisturizers, enhancing their effectiveness.

While some toners may provide hydration or have exfoliating properties, the core function remains centered around pH balance. This balance is important because it helps keep the skin barrier intact, which protects against environmental aggressors and prevents moisture loss. Additionally, a properly balanced pH can help with overall skin clarity and radiance, making toners a valuable step in the overall skincare process.
