Glycolic acid, a type of alpha hydroxy acid (AHA), is widely used in skincare for its exfoliating properties, helping to remove dead skin cells and promote cell turnover. A common side effect of glycolic acid is skin irritation or redness. This reaction occurs because glycolic acid can strip away not only dead skin cells but also some of the skin’s natural oils, leading to sensitivity, especially for those with sensitive skin or when used in high concentrations.

The irritation is characterized by symptoms such as stinging, burning, or redness, which typically indicates that the product is actively exfoliating the skin. Individuals with compromised skin barriers or underlying skin conditions may be particularly susceptible to these effects. Therefore, understanding that glycolic acid is potent and can lead to irritation is crucial for proper use and skin management.

Managing these effects often involves gradually introducing the product into a skincare routine, starting with lower concentrations, or ensuring proper hydration to mitigate irritation.
