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
| Concern | Filter | Pulse Duration | Fluence (Fitz III–IV) |
|---|---|---|---|
| Pigmentation | 530–590nm | 10–20ms | 12–18 J/cm² |
| Vascular/Redness | 530–570nm | 10–30ms | 14–20 J/cm² |
| Skin Rejuvenation | 560–590nm | 15–25ms | 12–16 J/cm² |
| Acne | 420–500nm | 10–20ms | 10–14 J/cm² |
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
