What Is Pico Laser? Treating Melasma, Freckles, Acne Marks — Price in Phitsanulok 2026

If you have melasma, freckles, or dark spots that you've tried many things for and still won't fade, until you start to feel discouraged and worried that it will be this way forever — I understand this feeling well. Pigment problems are genuinely frustrating and require patience.

Pico Laser is a technology that helps with pigment effectively and is backed by research, but it isn't a magic wand that clears everything in a single session. Dr. Time will explain honestly what it is, what it can treat, how many sessions are needed, and how to care for yourself — so that your expectations are realistic and you won't be disappointed.

What Is Pico Laser? How Does It Work?

Pico Laser is a laser that releases energy at the picosecond level (picosecond, 10⁻¹² seconds), which is hundreds of times faster than older lasers like the Q-switched. This breaks down pigment with a "shockwave" instead of "heat."

When energy this fast strikes pigment, the pigment shatters into very tiny fragments (photoacoustic effect), and the body sends cleanup cells (macrophages) to remove them more easily through the lymphatic system, while the surrounding tissue receives far less heat — so the chance of post-treatment dark marks is reduced. In addition, some modes also stimulate collagen production, helping with pores and acne scars too.

What Skin Concerns Can It Treat?

Pico Laser covers a wide range of pigment and skin concerns in a single machine, depending on the mode and wavelength selected.

• Melasma — helps it fade, but requires consistent treatment and strict sun protection
• Freckles, dark spots, post-acne dark marks (PIH) — break down excess pigment for more even skin
• Tattoos — shatter ink pigment for the body to remove
• Dull skin, large pores — refine the skin to be brighter and smoother
• Acne scars, uneven texture — when using fractional mode to stimulate collagen

Advantages Compared to Older Lasers

How Many Sessions Until You See Results?

Most cases require a course of 3–6 sessions, spaced 2–4 weeks apart, depending on the skin concern and the intensity of the pigment. Concerns like shallow freckles may show results quickly, while melasma, which is more complex, usually requires consistent treatment alongside sun protection and topical medications as recommended by your doctor.

Who Should Be Careful? Who Shouldn't Do It?

• Pregnant women
• Those with an infection, wound, or rash in the area to be treated
• Those who have recently had intense sun exposure or a fresh tan
• Those using certain medications that make the skin sensitive to light
• Those with melasma — must be treated by a doctor skilled at adjusting the energy, because settings that are too strong can make the melasma worse

How Much Does It Cost?

The price of Pico Laser depends on the concern being treated, the size of the area, and the number of sessions required. For example, treating freckles across the whole face, treating melasma, or removing a tattoo all cost differently. Dr. Time always assesses your skin and gives you a clear price before treatment, with no hidden charges. You can ask in advance via LINE.

Caring for Yourself After Treatment

• Apply sunscreen consistently and avoid intense sun (most important)
• Avoid scrubs, exfoliation, or irritating products during the first 3–5 days
• Keep the skin moisturized; slight redness will resolve on its own within a few hours to 1 day
• If small scabs appear (in the case of freckle removal), don't pick at them — let them fall off on their own
