Laser and light-based treatments address a wide range of concerns — from permanent hair reduction and sun damage to collagen remodeling and resurfacing. The key variables are wavelength (which determines what target the laser addresses) and energy level (which determines depth and downtime). Here's what to know before your consultation.
Laser hair removal uses targeted light energy to damage the follicle without affecting surrounding skin. It's effective on most body areas and produces permanent reduction — not guaranteed permanent elimination — over a series of 6–8 sessions. Sessions are spaced 4–8 weeks apart, timed to catch hairs in the active growth phase. Darker skin tones require a different wavelength (Nd:YAG at 1064nm) to avoid post-inflammatory hyperpigmentation; ask your clinician specifically about their protocol for your skin tone before booking.
Intense pulsed light (IPL) is technically not a laser — it emits a broad spectrum of light rather than a single wavelength. IPL targets hemoglobin (redness, broken capillaries) and melanin (sun spots, age spots) simultaneously, making it effective for patients dealing with both concerns at once. No downtime for most patients; sunspots may temporarily darken and flake off over 1–2 weeks. IPL is not suitable for darker skin tones — the broad spectrum increases the risk of burns or pigmentation changes.
Fractional resurfacing creates thousands of microscopic treatment columns in the skin while leaving surrounding tissue intact — speeding recovery compared to fully ablative treatments. Non-ablative fractional (e.g., Fraxel 1550) causes redness and swelling for 3–5 days; ablative fractional (CO2) produces more downtime (7–10 days) with more dramatic results. Hybrid devices like Halo combine both in one pass. Fractional resurfacing is among the most effective treatments for acne scarring, sun damage, and early laxity — but requires realistic expectation-setting about recovery.
