Which symptom is a common mild adverse effect immediately after treatment?

• A. Erythema
• B. Severe blistering
• C. Fever
• D. Nausea

Answer: (A)

The main idea here is how the skin typically reacts right after laser treatment. Erythema, or redness, is the common mild adverse effect because the skin briefly inflames as heat energy is absorbed by pigment in the hair follicles. This localized redness is expected, usually mild, and tends to fade within a few hours to a day. Severe blistering would point to overexposure or improper settings and isn’t a normal immediate reaction. Fever would be a systemic response, not a local skin reaction, and nausea isn’t tied to the skin’s post-treatment response.
