Question 1

Does Pico laser remove all pigmentation in one visit?

Accepted Answer

No. Stamp-like freckles and small lentigines may fade significantly after 1–2 sessions, but melasma, ABNOM, and Hori's nevus typically require 4–8 sessions spaced weeks apart for gradual, safe improvement. Single-visit 'complete removal' claims are inconsistent with how pigment biology actually works.

Question 2

Is Pico laser always better than Q-switched or IPL for pigmentation?

Accepted Answer

Not automatically. Picosecond lasers deliver energy in much shorter pulses (trillionths of a second) which creates more photoacoustic shattering of pigment and less thermal damage — a theoretical advantage. But for superficial pigmentation, long-pulse and Q-switched devices often work equally well at lower cost. The correct device depends on your pigment type and skin tone, not marketing.

Question 3

Can Pico laser make melasma worse?

Accepted Answer

Yes, if the settings are wrong. Melasma is notoriously prone to rebound after laser treatment, especially with aggressive fluence on Fitzpatrick III–IV skin. Conservative low-fluence fractional toning protocols are the current standard, and combining with oral or topical tranexamic acid improves outcomes. This is why specialist evaluation matters before any pigment laser on Asian skin.

Question 4

How does Pico laser treat tattoos differently than older lasers?

Accepted Answer

Picosecond lasers produce shorter, more intense pulses than Q-switched lasers, which more efficiently shatters tattoo pigment into smaller particles that the body can clear. Clinical data suggests fewer sessions are typically needed, particularly for difficult colors like green and blue. Old, faded black tattoos respond well; fresh, saturated tattoos still require 6–10+ sessions spaced 6–8 weeks apart.

Question 5

What is the downtime and recovery like?

Accepted Answer

For toning-level treatment: minimal — mild redness for 30 minutes to a few hours, you can wear makeup the next day. For fractional or ablative settings on freckles or tattoo: crusting for 5–10 days, scabs fall off naturally, followed by 2–4 weeks of pink new skin. Strict sun protection is required for at least 4 weeks after any pigment laser.

Question 6

How long is a Pico laser session, and is anesthesia needed?

Accepted Answer

An individual Pico laser pass typically takes about 10-15 minutes. Topical numbing cream is generally not required for standard toning-level treatment, although the dermatologist may apply it for more aggressive ablative settings on freckles or tattoo work depending on patient comfort.

Question 7

How many Pico laser sessions are typically planned overall?

Accepted Answer

Most pigment-focused programs are planned around 5-10 sessions in total, with exact spacing and count adjusted to pigment type — for example, melasma protocols typically run 4-8 sessions and saturated tattoos can require 6-10+ sessions, while small superficial freckles may fade significantly in 1-2 sessions.
