# Pigmentation: Every Treatment, Condition and Guide

Find the type first. Then the treatment.

Every IN Eternity Clinic page on melasma, freckles, sun spots, acne marks, pico laser and tattoo removal, each with a one-line summary, reviewed by Medical Director Dr Sin Yong.

Assessed and planned by [Dr Sin Yong](https://ineternityclinic.com/about-dr-sin-yong/), Medical Director · MBBS (NUS) · MRCS (Edinburgh) · MSc Aesthetic Medicine (London) · MSc Practical Dermatology (Cardiff) · [Designated DEKA Centre of Excellence](https://ineternityclinic.com/deka-centre-of-excellence/)

In short

This pigmentation hub lists every IN Eternity Clinic page on pigmentation: melasma, freckles, sun spots, acne marks (PIH), lip and underarm pigment, pico laser, laser toning and tattoo removal. Identify the type first, because it decides the treatment and the darkening risk in Asian skin. Each link opens a full page reviewed by Dr Sin Yong.

Key facts

- **Pigment lasers on site:** Fotona StarWalker PQX (picosecond and Q-switched) and DEKA TORO (pico and Q-switched), plus the FSX laser (thulium and erbium glass).
- **Check before laser:** a brown spot is examined before it is lasered; a spot that is changing, bleeding or unlike the others is assessed first and may not be lasered at all.
- **Type decides plan:** sun spots and freckles often respond in a few sessions, while melasma is usually controlled over time rather than cleared once.
- **Asian skin:** skin types III to V carry a higher risk of darkening after inflammation, so settings and spacing are chosen conservatively.
- **Who assesses:** Medical Director Dr Sin Yong, IN Eternity Clinic, 9 Scotts Road, #12-01 Pacific Plaza (MOH licence MDS/001/252).

Start here

## Which page should you read first?

Start with the page that matches what you already know. If you are unsure of the type, the concern page sorts it out; if you know the type, go straight to the treatment.

- [pigmentation concerns by type](https://ineternityclinic.com/concerns/pigmentation/) — Not sure what your marks are? This page matches each type of pigmentation to the treatments used for it.
- [pigmentation removal in Singapore](https://ineternityclinic.com/blog/pigmentation-treatment-singapore-guide/) — The main guide: sun spots, freckles, melasma, PIH and Hori’s naevus, sessions per type and darkening risk in Asian skin.
- [pigmentation treatment in Singapore by pigment type](https://ineternityclinic.com/pico-laser-pigmentation-singapore/) — How pico and Q-switched lasers are chosen once the pigment is typed, with melasma and PIH safety.

How to choose

## How do you choose a pigmentation treatment?

Choose by type, not by device: the same laser can help one brown mark and worsen another.

| What you see | Likely type (confirmed at assessment) | Read first | Usual first step |
|---|---|---|---|
| Flat brown patches on both cheeks, worse with sun, heat or hormones | Melasma | [melasma treatment in Singapore](https://ineternityclinic.com/melasma-treatment-singapore/) | Sun and heat control and medical care, with gentle laser only once stable |
| Sharp-edged brown spots on sun-exposed skin, appearing from your thirties | Sun spots (solar lentigines) | [age spot and sun spot removal](https://ineternityclinic.com/age-spot-removal-singapore/) | Spot check, then pico or Q-switched laser |
| Small light-brown dots since childhood that darken in the sun | Freckles | [freckles removal in Singapore](https://ineternityclinic.com/freckles-removal-singapore/) | Pico or Q-switched laser, with sun protection to slow their return |
| Brown marks where pimples were | Post-inflammatory pigmentation | [acne marks (post-inflammatory pigmentation)](https://ineternityclinic.com/conditions/post-inflammatory-pigmentation/) | Control the acne first, then gentle pigment care |
| Grey-brown or bluish patches on the cheekbones that appeared in adulthood | Possibly Hori’s naevus | [types of pigmentation in Asian skin](https://ineternityclinic.com/blog/pigmentation-types-asian-skin/) | A planned laser course, decided at assessment |
| Dark lips, dark underarms or dark circles | Several possible causes | [lip pigmentation treatment](https://ineternityclinic.com/lip-pigmentation-singapore/), [underarm whitening](https://ineternityclinic.com/underarm-treatment-singapore/), [dark eye circle treatment](https://ineternityclinic.com/dark-eye-circles-treatment-singapore/) | Cause checked first; treatment follows the cause |
| A spot that is changing, bleeding or looks different from your others | Needs a doctor’s check, not a laser | [mole check before removal](https://ineternityclinic.com/blog/mole-check-before-removal/) | Examination first; laser waits |

*How to choose a pigmentation page. A starting point only: the type is confirmed in person, and many faces have more than one type at once.*

Two people with “pigmentation” can need opposite plans. Sun spots sit high in the skin and often lift after one to a few laser sessions; melasma is driven by sun, heat and hormones and can darken if treated too hard. That is why the type comes first, and why every plan is decided at assessment.

Questions

## Frequently asked questions

**Which pigmentation page should I read first?**

If you do not know what your marks are, start with [pigmentation concerns by type](https://ineternityclinic.com/concerns/pigmentation/). If you already know, go to the treatment page for that type, such as melasma treatment or freckles removal. The main guide to [pigmentation removal in Singapore](https://ineternityclinic.com/blog/pigmentation-treatment-singapore-guide/) covers all the common types on one page, with sessions and darkening risk for each.

**Can pigmentation be removed for good?**

It depends on the type. Sun spots and freckles can often be lightened substantially, but new ones may form with further sun exposure. Melasma is a long-term tendency, so it is usually controlled rather than cleared once, and it can return with sun, heat or hormonal change. Upkeep and sun protection are part of every plan.

**Is pico laser safe for Asian skin?**

Pico laser is widely used in Asian skin, but skin types III to V darken more easily after inflammation, so settings, spacing and aftercare matter. At IN Eternity Clinic the pigment is typed first, a cautious first session is planned where risk is higher, and fresh tans and unstable melasma are reasons to wait.

**Why does the type of pigmentation matter?**

Each type sits at a different depth and has a different driver. Sun spots respond to targeted laser; melasma reacts to heat and needs gentler, combined care; acne marks fade once the acne is controlled. Treating the wrong type with the wrong settings can make pigmentation darker, so the type is confirmed before any plan.

**How many sessions does pigmentation treatment take?**

It varies between people and types. Sun spots often need one to three sessions; freckles a few; melasma and tattoos usually a longer course with maintenance. The number is estimated at assessment from the type, depth, area and your skin type, and reviewed as the skin responds.

**What should I do before a pigmentation consultation?**

Avoid tanning in the weeks before, bring a list of the creams and medicines you use, and note when the marks appeared and whether they change with sun or hormones. Photographs from earlier years can help. Dr Sin Yong examines the skin, and any spot that looks unusual is checked before laser is considered.
