What is the best way to clean a client's skin prior to laser treatment when they have no products on?

Cleaning the client's skin prior to laser treatment is essential to ensure that no contaminants interfere with the procedure. Using just water is appropriate in this case because it is gentle and effective for removing any surface dirt and oils without introducing harsh chemicals that could irritate the skin. Water will help in rinsing away impurities without leaving any residue that could interfere with the laser treatment.

While other options might be effective in different scenarios, they may not be suitable for every skin type or may lead to skin irritation. Alcohol can be harsh and drying, potentially irritating sensitive skin, while soap and water may leave a residue or could be too harsh for some individuals. Antibacterial wipes, while convenient, can also contain ingredients that might not be suitable for all skin types. Therefore, using just water is the most straightforward and least invasive method for preparing the skin before a laser treatment when no other products are present.
