What is a common side effect of using hydroxy acids?

Sensitivity is a well-recognized side effect of using hydroxy acids, such as alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs). These compounds are often used in skincare for their exfoliating properties, helping to remove dead skin cells and promote cell turnover. However, as they work to dissolve the bonds that hold dead skin cells together, they can also cause an increase in the skin's sensitivity, particularly among those with delicate or reactive skin types.

This heightened sensitivity may manifest as redness, irritation, or a stinging sensation, especially when first introducing hydroxy acids into a skincare regimen or when applying them in higher concentrations. It's essential for users to start slowly and monitor their skin's response to avoid adverse effects.

While acne breakouts can occur in some individuals due to the skin's adjustment to increased exfoliation, this is not a universal response nor as common as sensitivity. Improved texture is a primary benefit of hydroxy acids, and increased hydration is typically not a side effect directly associated with their use; rather, they might lead to dryness if not complemented with proper moisturization. Sensitivity stands out as a significant concern that users and practitioners should be aware of when incorporating these acids into skincare routines.
