If you have been researching how to treat pigmentation or acne scarring, you have probably come across both PicoSure and Fraxel — and possibly been told that one is simply “better.” That framing misses the point. They are different tools that solve overlapping problems in very different ways, and the right answer depends heavily on one thing: your skin type.
I should be upfront. At MARA.H we use PICOSURE® PRO, not Fraxel — so I have a clear bias. I will do my best to describe Fraxel fairly, because the purpose here is to help you choose correctly, not to dismiss a capable technology. Fraxel is a respected laser. It is simply not the tool we reach for, and the reason is specific to the skin we treat most: Asian and multicultural skin.
- PICOSURE® PRO — picosecond laser, shatters pigment by photomechanical pressure, low heat, non-ablative, no wound to the skin surface.
- Fraxel — fractional laser, resurfaces via thermal micro-injury columns, more downtime.
- The pivotal factor for Asian skin is heat — heat is the main trigger for post-inflammatory hyperpigmentation (PIH).
- Lower PIH risk profile generally favours PICOSURE® PRO on darker and Asian skin.
- For deep textural scars, MARA.H pairs PICOSURE® PRO with skin needling rather than ablative resurfacing.
Which is safer for Asian skin — PICOSURE® PRO or Fraxel?
For melanin-rich and Asian skin, PICOSURE® PRO is generally the safer starting point. It works by photomechanical pressure — shattering pigment with minimal heat — and is non-ablative, so it carries a lower risk of post-inflammatory hyperpigmentation (PIH). Fraxel works by thermal micro-injury and, in experienced hands on conservative settings, can be used on Asian skin, but its heat-based mechanism leaves a smaller margin for error on PIH-prone skin. For pigmented marks and overall tone, PICOSURE® PRO is the lower-risk choice; for deep indented scars, collagen induction is the priority, which at MARA.H is addressed with PICOSURE® PRO combined with skin needling rather than ablative resurfacing.
PicoSure vs Fraxel: The Technical Facts
Here are the underlying device facts first, so you can check them against any source you like before reading the interpretation.
- PicoSure / PICOSURE® PRO (Cynosure) — a 755 nm alexandrite laser that delivers energy in picoseconds (trillionths of a second). It works photomechanically: the pulse creates a pressure wave that shatters pigment, leaving minimal heat behind. It is non-ablative, so the skin surface is not removed. The PicoSure Pro platform is TGA-registered, and MARA.H operates the genuine Cynosure unit.
- Fraxel (Fraxel Dual) — a fractional laser using two infrared wavelengths: 1550 nm (erbium fibre), which reaches deeper into the dermis, and 1927 nm (thulium fibre), which works more superficially in the epidermis. It creates microscopic columns of controlled thermal injury, leaving untreated skin between them to speed healing. Non-ablative in this configuration; separate ablative CO2 Fraxel systems also exist.
- Where they diverge for Asian skin — the mechanism, not the brand. PicoSure clears pigment with pressure; Fraxel remodels skin with heat. Heat is the main trigger for post-inflammatory hyperpigmentation (PIH), which is why the thermal mechanism demands the more careful approach on Fitzpatrick III–V skin.
The Core Difference: Pressure vs Heat
Both lasers aim to improve pigmentation and skin texture, but the mechanism by which they do it is where they diverge — and that mechanism is everything when it comes to skin safety.
PICOSURE® PRO — Photomechanical, Low Heat
PICOSURE® PRO delivers energy in picoseconds (trillionths of a second). The pulses are so short that they shatter pigment through a photomechanical pressure effect rather than by burning it with sustained heat. The pigment is broken into fine particles the body then clears, while the surrounding tissue stays relatively cool and intact. Because it is non-ablative, it does not strip away the skin surface. Read more about PICOSURE® PRO at MARA.H, or see our companion comparison, PicoSure vs Q-Switch.
Fraxel — Fractional, Thermal Resurfacing
Fraxel is a fractional laser. It creates thousands of microscopic columns of controlled thermal injury across the skin, leaving surrounding tissue intact to speed healing. This stimulates a strong resurfacing and collagen response, which can be effective for texture and certain pigmentation. The trade-off is that the mechanism is fundamentally thermal — and that is precisely the variable that requires the most caution in darker skin.
| Factor | PICOSURE® PRO | Fraxel |
|---|---|---|
| Laser type | Picosecond (pressure) | Fractional (thermal) |
| Wavelength / platform | 755 nm alexandrite, picosecond | 1550 nm erbium + 1927 nm thulium |
| Primary mechanism | Photomechanical, low heat | Thermal micro-injury |
| Surface | Non-ablative | Non-ablative to ablative |
| Depth targeted | Pigment in epidermis and upper dermis | 1550 nm deeper dermis; 1927 nm superficial |
| PIH risk on dark skin | Lower risk profile | Requires careful management |
| Downtime | No wound to the skin surface | Moderate (days) |
| Strongest for | Pigment, tone, PIH-prone skin | Deep textural resurfacing |
Why Heat Is the Deciding Factor for Asian Skin
This is the heart of the comparison, and it is the same principle we explain on every laser page we write. In melanin-rich skin, the pigment-producing cells (melanocytes) are more reactive. When they are exposed to significant heat and inflammation, they can respond by producing more pigment — a reaction called post-inflammatory hyperpigmentation (PIH). The cruel irony is that a treatment intended to remove dark marks can, if it generates too much heat in the wrong skin, leave behind new ones.
This is why the pressure-based, low-heat mechanism of PICOSURE® PRO is so well suited to Asian and darker skin: it minimises the very variable that drives PIH. It is also the same logic behind our PicoSure vs Q-Switch comparison — older heat-based pigment lasers carry the same caution.
None of this means Fraxel cannot be used on Asian skin. In experienced hands, with conservative settings and careful pre- and post-care, it is used on darker skin types. But it demands a higher degree of caution and operator skill precisely because its mechanism is thermal — and the margin for error on PIH-prone skin is smaller.
“For the skin we see most in Chatswood, the first question is never ‘which laser is most powerful’ — it is ‘which laser is least likely to make pigmentation worse.’ That question consistently points us toward picosecond technology. Power without safety is not a result; it is a risk.”

What About Acne Scars?
This is where the comparison gets more nuanced, because acne scarring is not one problem — it is several. The right tool depends on which type of scar you actually have.
- Pigmented marks (PIH and PIE) — flat brown or red marks left after a breakout. PICOSURE® PRO’s pigment-targeting action handles these well, with low PIH risk.
- Deep indented or textural scars — ice-pick, boxcar, rolling scars. These need collagen rebuilding. Fraxel’s resurfacing can address texture, but it does so thermally.
At MARA.H, rather than reaching for ablative fractional resurfacing on Asian skin, we address textural scarring by combining PICOSURE® PRO with clinical skin needling — collagen induction that rebuilds structure mechanically, keeping the thermal load (and therefore PIH risk) low. For a full breakdown of scar types and our protocol, see our acne scar treatment page.
What We Offer — and What We Don’t
To be transparent: MARA.H uses PICOSURE® PRO for pigmentation and scar revision, and clinical skin needling for textural and indented scarring. We do not offer Fraxel.
That is a deliberate choice, not a criticism of the technology. We built our laser offering around the safest, most predictable results for the skin we treat most — and for pigmentation-prone Asian and multicultural skin, a low-heat, pressure-based approach is the foundation we trust.
How we decide at MARA.H: every pigmentation or scar consultation begins by correctly classifying the concern — is it pigment, texture, or both, and what is your skin’s PIH risk? Only then do we design a protocol. If the honest answer is that a technology we don’t offer would genuinely suit you better, we will tell you. Book a skin assessment here.
