Intense Pulsed Light (IPL) photofacial treatments are among the most popular and versatile services in beauty salons. IPL effectively addresses pigmentation, redness, enlarged pores, and uneven skin tone — making it an essential treatment for any salon serving the Southeast Asian market.

What is IPL?

Unlike lasers that emit a single wavelength, IPL delivers a broad spectrum of light (typically 500–1200nm) through interchangeable filters. This allows a single device to treat multiple skin concerns:

• Pigmentation & sun damage: Light is absorbed by melanin, fragmenting pigment clusters
• Vascular lesions & redness: Light targets hemoglobin, causing vessel coagulation
• Collagen stimulation: Thermal effect promotes new collagen production
• Acne: Blue-light filters target P. acnes bacteria; redness from inflammation is reduced

Pre-Treatment Preparation

• Client Consultation & Skin Assessment:
  • Determine Fitzpatrick skin type — critical for safe parameter selection
  • Identify all active skin conditions: rosacea, melasma, active acne, eczema
  • Check for contraindications: pregnancy, photosensitizing medications, history of keloids, recent isotretinoin use (within 6 months), active herpes simplex (consider prophylactic antiviral)
• Pre-Treatment Skincare (2–4 weeks before):
  • Avoid sun exposure and tanning beds for 4 weeks minimum
  • Discontinue retinoids, AHAs/BHAs 5–7 days before treatment
  • Daily SPF 50+ sunscreen application
  • No laser, chemical peel, or microdermabrasion for 2 weeks prior
• Day of Treatment:
  • Thoroughly cleanse and degrease the skin
  • No anesthetic needed for most IPL treatments (comfort level is typically well-tolerated)
  • Apply a uniform layer of cold IPL coupling gel (1–2mm thick) to the treatment area
  • Provide protective eyewear for both client and operator

Treatment Protocol

Step 1: Filter & Parameter Selection

Safety tip for Asian skin: Always start with lower fluence and longer pulse duration. Asian skin (Fitzpatrick III–V) has a higher risk of post-inflammatory hyperpigmentation (PIH). Perform a test patch on a small area behind the ear or along the jawline and wait 24–48 hours before full treatment.

Step 2: Treatment Delivery

• Hold the handpiece perpendicular to the skin with full contact.
• Apply slight pressure to ensure consistent skin contact through the gel layer.
• Deliver pulses in a systematic pattern — start from the forehead, move to cheeks, then chin and nose.
• Slight overlap (approximately 10%) between pulses for even coverage.
• Avoid treating directly over the eyebrows, eyelids, and lips.
• The client should feel a warm snapping sensation — like a rubber band flicking the skin. If pain is excessive, reduce fluence.

Step 3: Clinical Endpoints

• Pigmentation: Darkening of lesions within minutes (coffee-ground appearance) — this is desired and indicates effective treatment
• Vascular: Immediate blanching or darkening of vessels; perivascular erythema
• Rejuvenation: Mild, uniform erythema across the treatment area

Post-Treatment Care

Days 1–3: Acute Phase

• Mild redness and warmth (similar to a mild sunburn) is expected for 2–6 hours
• Apply cool compresses or a soothing gel mask as needed
• Do not wash the face with hot water — use lukewarm or cool water only
• No makeup for 24 hours
• No active skincare ingredients (retinol, AHA/BHA, vitamin C) for 3–5 days

Days 3–7: Pigment Darkening & Exfoliation

• Treated pigmentation will darken further before flaking off — reassure the client this is normal
• Pigment “coffee grounds” will naturally exfoliate in 5–10 days
• Do not scrub, pick, or use exfoliants
• Moisturize liberally with gentle, fragrance-free products

Long-Term Maintenance

• Absolute sun protection: SPF 50+ daily, reapply every 2–3 hours outdoors. UV exposure is the #1 cause of pigmentation recurrence
• Avoid photosensitizing foods in excess: celery, parsley, citrus (when going outdoors)
• Maintain with antioxidant skincare (niacinamide, vitamin C, green tea extract)
• Consider oral supplements: Vitamin C, tranexamic acid (under professional guidance)

Treatment Schedule

• Standard course: 4–6 sessions at 3–4 week intervals
• Melasma: 6–10 sessions; combine with topical therapy for best results
• Maintenance: 1 session every 1–2 months
• Skin cell turnover cycle is approximately 28 days — this is why 3–4 week intervals are recommended

Preventing Post-Inflammatory Hyperpigmentation (PIH)

PIH is the most common adverse effect in Asian skin. Prevention strategies:

• Conservative fluence — start low, increase gradually
• Longer pulse durations for darker skin types
• Double or triple pulsing with delay instead of single high-energy pulse
• Adequate cooling between passes
• Strict pre- and post-treatment sun protection
• Consider pre-treatment with topical hydroquinone or tranexamic acid for 2–4 weeks
