What melasma treatment costs in Bangkok
On 4 November 2026 we read the prices that three Bangkok hospitals and two Bangkok clinics publish on their own websites, each page dated within the past year. Two of the hospitals belong to the same group. Pages giving only general market prices were left out:
| Treatment | Published prices |
|---|---|
| Q-switched laser, one session | 4,500 baht at one hospital, open to Thai and foreign patients; 5,500 baht at another, for Thai citizens and foreigners living in Thailand. |
| Pico laser, one session | 4,500 baht at one clinic; 10,000 baht with a vitamin infusion at one hospital. |
| Courses | 27,000 baht for five Q-switched sessions, or for three pico sessions, at one hospital; 20,000 baht for five pico sessions and 35,000 baht for ten at one clinic. |
| Tranexamic acid injection | 3,400 baht for a melasma injection of 5 ml of tranexamic acid (Transamin) at one hospital. |
| Light and other lasers | 2,700 baht a session for a VIPL light treatment and 4,000 baht a session for a Z-Smooth laser at one clinic. |
| Starting price only | From 2,000 baht for a Spectra Gold laser at one hospital, depending on the number of sessions and the area. |
Two hospitals' packages include the doctor's fee and hospital charges. At one of them they are discounted programme prices for Thai citizens and foreigners living in Thailand only; the other hospital in the same group says its laser price applies to both Thai and foreign patients. The pico packages are sold for acne scars, freckles and dark spots as well as melasma.
What melasma is, and how it is treated
One hospital describes melasma as pigment lying deep in the skin, showing as large dark or brown patches on the forehead, cheeks, nose and above the lip, and often linked to hormones, such as pregnancy or the contraceptive pill.
The prices above cover four kinds of treatment: Q-switched laser toning, picosecond laser, light treatment, and injections of tranexamic acid. Ask the doctor which suits your melasma, and whether they advise combining them.
How many sessions
One clinic says melasma usually needs about three to five pico sessions or more for a clear result. One hospital sells courses of three and five sessions, and one clinic courses of five and ten. None of these pages says how far apart the sessions should be or how long the result lasts, so ask before you buy a course.
Aftercare, and who should wait
One clinic usually applies numbing cream before pico laser, and says slight redness afterwards improves over one to two days. One hospital advises avoiding the sun for one to two weeks before treatment and stopping fruit acids and exfoliants three to five days before; afterwards, sunscreen and no strong sun for one to two weeks, no scrubs or acids until the doctor allows, and no sauna, steam or hard exercise for two to three days. It asks you to see a doctor at once if the skin becomes red, raised or more irritated than expected.
One hospital says its Q-switched laser is not suitable for people with inflamed acne, which may get worse. Another asks you to tell the doctor about any illness, and any medicine that makes the skin sensitive to light.
Check who treats you
Only a doctor registered and licensed by the Medical Council of Thailand may practise medicine (Medical Profession Act 1982, section 26). Ask for the name of the doctor who will treat you, and check it on the Medical Council's website by searching their first name and surname, in Thai or in English. It lists only licensed doctors. If you find nothing, the Council answers on 02-590-1887.
No one may present themselves as skilled in a field of medicine unless they hold the Medical Council's certificate for it, or one the Council recognises, or meet criteria set in the Council's regulations (section 28).
What to ask before you pay
- Which method do you advise for my melasma, and why?
- How many sessions, how far apart, and what does the course cost?
- Does the price apply to me as a visitor?
- What should I do afterwards to keep the melasma from coming back?
- What is the doctor's full name?
