What would be unusual for the client to experience during a light glycolic peel?

• A. Mild tingling
• B. Moderate erythema
• C. Temporary numbness
• D. No change in sensation

Answer: (B)

In a light glycolic peel, the skin’s reaction is shallow and mild. You’d expect only a light tingling as the acid penetrates the outermost layers, and any visible redness is typically minimal or absent. Moderate erythema, on the other hand, signals more inflammation than a superficial peel should cause. It suggests the treatment was stronger than intended—perhaps a higher acid concentration, longer exposure, or unusually sensitive skin—and would be unusual for a light peel.

So the common experience is a light tingling with little to no redness, while moderate erythema would stand out as atypical and indicate the treatment was more aggressive than intended.
