For pigmentation (dark spots, melasma, sun damage) on Latin/darker skin, the choice is rarely IPL. IPL emits broadband light absorbed by melanin — meaning it works on light skin with discrete spots but can paradoxically darken patches on Fitzpatrick IV–VI. Picosecond's selective wavelengths and ultra-short pulses are far safer.
This guide covers the mechanism difference, the safety case for picosecond on darker skin, and when each technology is appropriate.
How IPL works
Broadband light (500–1200 nm) targets melanin (dark spots) and oxyhemoglobin (redness). Effective on light skin with discrete spots. On darker skin, the broad spectrum is absorbed by background melanin, causing burns and pigment shifts.
IPL's appeal is its breadth — it can address spots, redness, and texture in one device. The trade-off is that breadth doesn't translate to safety across skin types.
Why picosecond is safer for Latin skin
Picosecond uses specific wavelengths (532, 755, 1064 nm) and ultra-short pulses that minimize thermal injury. Result: melanin is fragmented without heat damage to surrounding skin.
The selectivity matters. A 532 nm picosecond pulse targets specific superficial pigment without disturbing background melanin. IPL's broad spectrum hits everything melanin-rich.
Effectiveness on melasma
Melasma is a chronic condition. Picosecond toning protocols (low-fluence multiple-pass treatment) outperform IPL by a wide margin and rarely cause flares. IPL on melasma is contraindicated for most Latin skin types.Picosecond's mechanism — fragmenting pigment without inflammation — is well-suited to melasma's reactive nature. IPL's heat triggers melanocyte activation and often worsens melasma.
Recovery and sessions
- Picosecond pigmentation: 4–6 sessions, 4 weeks apart, no real downtime
- IPL pigmentation: 3–5 sessions but with higher recurrence risk
Both are tolerable per-session. Picosecond's more reliable result trajectory makes the multi-session investment worthwhile.
Skin-tone fit
| Fitzpatrick type | IPL safety | Picosecond safety |
|---|---|---|
| I-II (very light) | Excellent | Excellent |
| III (light-medium) | Good | Excellent |
| IV (medium) | Caution required | Excellent |
| V (medium-dark) | Often contraindicated | Good with careful protocol |
| VI (dark) | Contraindicated | Good with careful protocol |
Cost (Elyzea)
Picosecond pigmentation: S/300 (~US$86). Picosecond melasma: S/300 (~US$86).
IPL availability in Lima exists but isn't the recommended pigmentation tool at most modern clinics.
When IPL is still the right choice
Even on Fitzpatrick I-III patients, IPL has specific use cases:
- Combined redness + spot treatment: IPL handles both vascular and pigmented lesions
- Rosacea with sun damage: IPL's vascular component addresses the diffuse redness
- Cost constraints: some markets offer IPL cheaper than picosecond
For light-skinned patients with combined vascular + pigmented concerns, IPL remains valuable.
Combining picosecond with topical therapy
Most pigmentation protocols layer:
- Daily mineral SPF 50+
- Hydroquinone 4 % (cycling 3 months on / 1 month off)
- Tretinoin nightly
- Niacinamide morning
- In-clinic picosecond every 4 weeks during active treatment phase
Topicals do 60-70% of the work. In-clinic compounds the result.
Frequently asked questions
Does picosecond work on freckles?
Yes — but freckles often return with sun exposure. Maintenance approach.
What about red spots (telangiectasias)?
Picosecond doesn't target redness. Vascular laser or IPL on light skin needed.
Can I do picosecond + IPL?
Possible but rarely needed. Picosecond covers most indications adequately.
How does picosecond compare to laser toning Q-switched?
Picosecond uses lower fluence with faster pulses — more effective and safer than older Q-switched laser toning.
Will my melasma come back?
Likely yes if sun exposure resumes. Lifelong management.
Can I do picosecond during pregnancy?
Generally no. Postpone until after pregnancy and breastfeeding.
What about microneedling for pigmentation?
Microneedling alone doesn't treat pigmentation. RF microneedling (Morpheus8) carries some risk on darker skin.
Bottom line
For Latin skin specifically, picosecond is the right tool for pigmentation. IPL's broad spectrum makes it unsafe at common Fitzpatrick levels in Lima patients. Elyzea's picosecond pigmentation protocols at ~US$86 per session produce reliable results with minimal complication risk.
