Excessive redness and blistering are clear indicators of an adverse reaction following a laser hair removal treatment. These symptoms suggest that the skin has experienced a significant reaction to the laser energy, which may result from overheating or improper settings being used during the procedure. In normal circumstances, some redness might occur following treatment, but excessive redness paired with blistering signifies a more severe response that could indicate thermal injury to the skin. This requires careful assessment and possibly intervention from the practitioner to manage and mitigate further complications.

In contrast, while regular skin pigmentation changes might occur during the healing process or in response to sun exposure, they do not typically indicate an immediate adverse reaction. Light irritation without pain is often a normal response to laser treatment and may resolve within a short period. New hair growth in treated areas can indicate that the treatment was ineffective or that hair growth cycles are still in play; however, it is not classified as an adverse reaction.
