What pH range is considered acidic for cosmetic products?

The pH range considered acidic for cosmetic products is from 1 to 6. In this range, products have a higher concentration of hydrogen ions, which contributes to the acidity. This is significant in the cosmetic industry because certain acidic products can be beneficial for the skin. For example, alpha hydroxy acids (AHAs) often fall within this range and are used for chemical exfoliation and improving skin texture.

Products with a pH lower than 7 are generally seen as more compatible with the skin's natural acid mantle, helping to maintain the skin's barrier function and prevent irritation. It's important for estheticians to understand this pH range to choose and recommend products that will improve skin health effectively. A pH lower than 7 is essential for creating formulations that promote skin exfoliation or maintain hydration depending on the intended treatment.

The other options represent neutral or alkaline pH values, which do not fall within the acidic category relevant for effective cosmetic applications targeting specific skin concerns. Understanding the pH scale is crucial for professionals in the field to ensure they are selecting the right products for desired outcomes in skincare.
