What common side effect might occur after a laser treatment?

Erythema, or redness, is a common side effect following laser treatment due to the impact of the laser energy on the skin. During a laser procedure, the skin can experience thermal injury as the laser targets specific areas, which triggers an inflammatory response. This response causes increased blood flow to the treated area, resulting in redness. The degree of erythema can vary depending on the type of laser used, the intensity of the treatment, and the individual's skin type, but it is typically a temporary condition that resolves as the skin heals.

While hyperpigmentation, scarring, and itching can also occur after laser treatments, erythema is the most prevalent and immediate reaction observed in most patients. Understanding this common reaction helps both practitioners and patients anticipate and manage potential side effects effectively.
