Why is it important to tone the skin after cleansing?

Toning the skin after cleansing is important primarily because it helps to restore the skin's pH balance. The skin's natural pH typically ranges from 4.5 to 5.5, which is mildly acidic. Cleansers, particularly those that are alkaline or contain strong ingredients, can disrupt this balance, leading to issues such as dryness, irritation, or an overproduction of oil.

Using a toner helps to quickly bring the skin back to its optimal pH level, which is crucial for maintaining its protective barrier and overall health. This balance is essential for the skin's ability to function properly and to prevent conditions such as acne or sensitivity.

While toning can also assist in the application of skincare and makeup, its primary role remains focused on pH restoration. Moreover, enhancing fragrance is not a fundamental purpose of toner; thus, this aspect is secondary compared to the skin health benefits associated with maintaining its pH.
