Improper operation is the primary cause of "ineffective results" or "burn injuries." Adhering to the following clinical-grade Standard Operating Procedures (SOP) will maximize both efficacy and safety:
Phase 1: Pre-Treatment (Skin Preparation)
Surface Hair Removal: Strictly avoid plucking or waxing (as this removes the hair shaft—the target for treatment—rendering IPL ineffective). Use a razor to shave the hair clean, leaving a stubble of 1–2 mm to ensure light energy reaches the hair follicles directly.
Clean and Dry: Remove all oils and cosmetics; ensure the skin remains completely dry to prevent light energy refraction.
Phase 2: During Treatment
Vertical Contact: Ensure the light emission window is positioned completely vertically and pressed firmly against the skin to prevent light leakage or energy scattering.
Intensity Strategy: Begin with the lowest intensity setting. If no significant stinging sensation or redness/swelling occurs, gradually increase the intensity level during subsequent sessions. Note: Pain does not equate to efficacy; any burning sensation should subside within one minute.
Sequence and Coverage: It is recommended to proceed by specific body zones (e.g., lower legs → arms → underarms). Ensure the overlap rate between light pulses does not exceed 10% to avoid over-exposure to the same area.
Phase 3: Post-Treatment Care
Immediate Cooling: Apply medical-grade aloe vera gel or a cold compress to soothe the skin and alleviate any transient redness (erythema).
Strict Sun Protection: Avoid exposure to ultraviolet (UV) light for 48 hours post-treatment. For long-term use of the device, apply SPF 30+ sunscreen daily to prevent hyperpigmentation.
Avoid Irritants: For 24 hours following treatment, refrain from taking hot baths, using saunas, or applying irritating skincare products (such as fruit acids or retinol).
