Pico Laser Questions —
Answered Without The Hype

"Pico" is a pulse length, not a brand or a single treatment. A pico laser fires pulses measured in picoseconds, trillionths of a second, so pigment or ink is broken mainly by a pressure effect rather than by heat. Less heat spreads into the skin, which matters because inflammation is what leaves brown marks in Asian skin. At Atelier the device is the DEKA TORO; the mechanism is explained on the pico laser page.

The same laser works in three quite different modes: spot treatment for single marks, low-energy toning across the face for diffuse pigment, and fractional delivery for texture. Most confusion online comes from comparing one mode's experience with another's.

Where a pico laser is useful:

• Discrete pigment such as freckles and sun spots, treated spot by spot (pico laser for freckles).
• Diffuse uneven tone, on gentle toning settings.
• Tattoo ink (tattoo removal).
• Fine texture and the look of pores, through fractional delivery.

Where it is not the answer:

• Pores: fractional pico can soften their appearance, but it does not shrink them directly, and response varies.
• Deeper acne scars: it does not treat the walls of boxcar scars, the tethers under rolling scars or ice pick tracts. Those need subcision, TCA CROSS, fractional CO2 or RF microneedling; acne scar treatment sets out the sequence.
• Red marks: a pico laser targets brown pigment, not blood vessels (red vs brown marks).
• Skin whitening: it targets abnormal pigment and does not change your natural skin colour.
• Melasma: it can lighten visible pigment, but melasma is managed, not removed.

There is no single number of days, because each mode heals differently:

• Toning: pinkness and warmth that usually settle within hours.
• Spot: each mark darkens, then a fine crust forms and flakes off over several days. The spot looks darker before it looks lighter.
• Fractional: pinpoint redness and mild swelling, then a rough, sandpapery feel that lasts longer than either of the others.

Throughout, leave crusts alone, keep active skincare off until the surface settles, and wear broad-spectrum sunscreen every day. The full timeline is on pico laser downtime.

New darkening after a pico laser is usually post-inflammatory hyperpigmentation. The common causes are energy set too high, sessions repeated too soon, sun on freshly treated skin, and melasma mistaken for a sun spot and treated like one.

It can appear weeks after a session, when the skin looked calm the next day, and it can take months to fade. Adding another laser session or a strong active while the skin is inflamed tends to make it worse. It should be assessed and allowed to settle, not treated over.

Because toning feels gentle, it is sometimes booked like a monthly facial. It is a medical treatment with a cumulative dose. Frequent repeated toning of the same area has been linked with pale, mottled spots, which are harder to correct than the original pigment.

Toning at Atelier has a defined aim, a check after each session and a point at which it stops. How often any maintenance happens depends on how the skin responds, not on a calendar, and daily sun protection does more to keep results than extra sessions. Laser toning vs pico laser compares nanosecond and picosecond toning, and carbon laser peel covers a different, surface-level treatment that is often confused with both.
