Can laser resurfacing cause scarring?

For readers in Dexter, Michigan, the scarring question deserves an answer before any resurfacing date goes on the calendar.

The direct answer

my.clevelandclinic.org says scarring after laser skin resurfacing, although very rare, may occur in laser-treated areas. my.clevelandclinic.org adds that the risk is greater when the laser light penetrates more deeply than other lasers, because healing can become more complicated.

Where depth enters the sequence

Depth is the first thing to pin down, because the source ties the greater risk to how deeply the light penetrates. Ask the provider which laser will be used and how deep it works, and write the answer down.

What to gather

• The name of the device and the provider's description of its depth.
• A list of any scars you already have in the areas to be treated.
• Photos of those areas as they look today.
