• Pain: Pain may be felt during the procedure, especially when treating sensitive areas.
• Erythema and edema: After the procedure, the treatment area may experience erythema and edema, which usually subside within a few days.
• Burns: If the energy is too high or the operation is improper, it may cause skin burns.
• Blisters: After the procedure, blisters may appear in the treatment area, which usually absorb on their own within a few days.
• Pigmentation: After the procedure, hyperpigmentation may appear in the treatment area, which usually fades within a few weeks or months.
• Scarring: In rare cases, scarring may occur after treatment.

[Here are some factors that may lead to adverse reactions]:

• Client's skin type: Sensitive skin is more prone to adverse reactions.
• Treatment site: Sensitive areas are more prone to adverse reactions.
• Treatment parameters: Excessive energy or pulse width may increase the risk of adverse reactions.
