Which skin-related factor is crucial to assess before an AHA treatment?

Assessing the client's skin type is crucial before administering an Alpha Hydroxy Acid (AHA) treatment because it directly impacts how the skin will react to the chemical process induced by AHAs. Different skin types—such as oily, dry, combination, or sensitive—respond differently to exfoliation and active ingredients.

For example, oily skin may tolerate higher concentrations of AHAs better than dry or sensitive skin, which could experience irritation or adverse reactions. Understanding the client's skin type helps estheticians tailor treatments appropriately, minimizing risks and enhancing results. A tailored approach ensures that the AHA treatment is effective while maintaining the integrity and health of the skin.

While hydration level, pain tolerance, and sun exposure are important factors in an overall treatment plan, the skin type is foundational for determining the suitability of AHA treatments specifically.
