What is the maximum recommended concentration of AHA's in skin products?

The maximum recommended concentration of AHAs (Alpha Hydroxy Acids) in skin products is typically around 10%. AHAs are widely used in skincare products for their ability to exfoliate the skin, improve skin texture, and promote cell turnover, making them beneficial for issues like acne and pigmentation.

At a concentration of 10%, AHAs can effectively deliver these benefits while minimizing the risk of irritation and adverse reactions that can occur with higher concentrations. Products with concentrations exceeding this level may lead to excessive skin sensitivity, irritation, or even damage, especially in individuals with sensitive skin types.

For context, while higher concentrations, such as 15% or 20%, might provide more dramatic results in professional settings, they are generally not recommended for over-the-counter products meant for home use. Therefore, keeping the concentration around 10% helps ensure safety and efficacy in consumer products.
