What is the maximum concentration of salicylic acid allowed by the FDA for cosmetic formulations?

1. One percent

2. Two percent

3. Three percent

4. Four percent

The correct answer is: Two percent

The maximum concentration of salicylic acid allowed by the FDA for cosmetic formulations is two percent. This concentration level is deemed safe and effective for use in over-the-counter products, particularly for treating acne and other skin conditions where salicylic acid functions as a keratolytic agent. At this concentration, salicylic acid helps to exfoliate the skin by dissolving dead skin cells, preventing acne blockages, and providing anti-inflammatory benefits. Higher concentrations of salicylic acid are generally reserved for prescription treatments or specific dermatological applications, as they may increase the risk of irritation or adverse effects in the general population. Therefore, understanding the regulatory limits set by the FDA is crucial for practitioners in the field to ensure compliance with safety standards and optimize treatment efficacy.
