Laser treatment for melasma, freckles, dark spots, birthmarks and tattoos (Blemish Eraser)
A short-pulse picosecond laser fires energy that shatters pigment beneath the skin into tiny particles, which the body then clears on its own. Suited to deep freckles, dark birthmarks, dark spots and tattoos, with a dermatologist assessing the depth of the pigment first.
How pigment lasers work
Melanin and tattoo ink are particles that absorb certain wavelengths of light well. When an extremely short laser pulse hits them, the energy is released so quickly that the particles shatter before heat can spread and damage the surrounding skin. White blood cells then clear these fragments through the lymphatic system over the following weeks. Older nanosecond (Q-switched) lasers deliver longer pulses, so they generate more heat and carry a higher risk of post-treatment darkening. Picosecond lasers deliver pulses roughly a thousand times shorter, so they can use lower energy, break pigment into finer particles and suit Thai skin, which darkens easily. The clinic offers 1064 nm for deep pigment and darker skin, and 532 nm for superficial pigment.
Which lesion, which approach
| Concern | Depth | Approximate sessions |
|---|---|---|
| Sun freckles, superficial freckles | Epidermis | 1–3 sessions |
| Post-acne and post-inflammatory dark marks | Epidermis to upper dermis | 3–5 sessions, with topical treatment |
| Deep freckles (Hori's naevus), naevus of Ota | Dermis | 5–10 sessions, 6–8 weeks apart |
| Melasma | Mixed, both layers | Low-energy toning as part of the melasma programme |
| Black/blue tattoos | Dermis | 6–10 sessions, 6–8 weeks apart |
| Coloured tattoos (red, green) | Dermis | More than black; some colours do not fade completely |
On the day
The clinic uses a Thai FDA-registered pigment laser [device name] with 1064/532 nm wavelengths. The doctor can tell you the device name and the parameters used on request
Are pregnant, have had strong sun exposure within 2 weeks, have taken isotretinoin within 6 months, have a cold sore or skin infection in the treatment area, have a history of keloids, or have a lesion suspected of being a tumour, which must be excised and sent for histology rather than lasered
Pink lip laser
Lips darkened by accumulated pigment, smoking or embedded lipstick dye can be treated with a low-energy pigment laser across the whole lip, 3–5 sessions spaced 2–4 weeks apart. The lips are red, dry and flaky for 3–5 days. It should not be done during an active cold sore or if you have had dark lip tattooing, because some inks turn black under the laser. Avoid dark or matte lipstick for 3 days afterwards.

Read more →Frequently Asked Questions
Will freckles come back after laser?
A freckle that has been cleared does not return in the same spot, but sun-exposed skin can form new ones. Daily sunscreen is therefore part of the treatment.
Can darker skin be treated? Is there a risk of dark marks?
Yes, using the 1064 nm wavelength and appropriately adjusted energy. There is a risk of temporary darkening, which usually fades on its own within 1–3 months, and the doctor prescribes topical medication to help.
Can a tattoo be removed completely?
Black and blue inks respond well, generally within 6–10 sessions. Red, green and yellow inks and some eyebrow tattoo pigments fade slowly or incompletely. The doctor gives you an honest assessment before you begin.
Can melasma be treated with a pigment laser alone?
We do not recommend it. Melasma responds to laser but returns quickly without topical treatment and sunscreen, and excessive energy can make it darker. We therefore use low energy only as part of the melasma programme.
