How can previous skin treatments affect future laser therapy?

Previous scars or injuries can significantly alter how the skin reacts to laser therapy. When the skin has undergone previous treatments, it may have altered its texture, pigmentation, or healing response. Scars may cause changes in skin thickness or sensitivity, which can impact how the skin absorbs the laser energy and how it heals afterward.

Understanding these factors is crucial for practitioners to tailor the laser treatment appropriately for the individual’s skin condition and history. For example, individuals with a history of keloid scarring may require a different approach to minimize the risk of further complications.

Recognizing the influence of previous skin treatments helps practitioners anticipate potential reactions and adjust parameters to optimize the effectiveness of the laser therapy while ensuring the patient's safety.
