Look for toners specifically formulated for sensitive skin, often labeled as 'gentle' or 'soothing'. Key ingredients to seek out include hyaluronic acid, aloe vera, and chamomile, while avoiding alcohol, fragrances, and harsh exfoliants like AHAs/BHAs.

People with sensitive skin can use toner, but it's crucial to choose a gentle, alcohol-free formula. Toners can help balance pH levels and hydrate the skin after cleansing, but always patch test a new product before applying it to the entire face.

In Korean skincare, toners (often called 'skin' or 'refining toners') are used to hydrate and prep the skin for subsequent products. Many Korean toners feature hydrating ingredients like hyaluronic acid, green tea extract, and rice water, focusing on gentle hydration and balance.

The safest toners are typically those with minimal ingredients and free of alcohol, fragrances, and harsh chemicals. Look for hypoallergenic and dermatologist-tested options formulated for sensitive skin to minimize the risk of irritation.
