Which of the following treatments can be part of preparation before laser skin treatments?

Avoiding sun exposure is a crucial preparation step before undergoing laser skin treatments. Sun exposure can increase the risk of complications and negatively affect the results of the treatment. When the skin is tanned or sunburned, it becomes more sensitive, which can lead to an increased chance of side effects such as burns or pigmentation issues during the laser procedure. Proper skin preparation often includes keeping the area protected from the sun for a period leading up to the treatment, allowing for safer and more effective results.

The other options do not contribute positively to skin preparation. Adding heavy makeup can clog pores and may interfere with the effectiveness of the laser treatment. Using abrasive scrubs can irritate the skin and can cause microtears or inflammation, making the skin more sensitive prior to laser procedures. Neither heavy makeup nor abrasive scrubs align with best practices for skin readiness ahead of laser treatments.
