After a pimple heals, it often leaves a flat brown or dark mark that lingers for weeks or months. This is post-inflammatory hyperpigmentation, or PIH: pigment cells overreact to inflammation and leave extra melanin behind. It is not a scar, because the surface is flat and the texture is normal. Acne marks removal in Singapore is one of the most frequent skin requests, because PIH is especially common in Asian skin.
When skin is inflamed, signals released during healing stimulate pigment cells to produce more melanin. If that pigment stays in the epidermis, the mark looks brown and fades faster. If inflammation damages the base of the epidermis, pigment drops into the dermis, where it looks grey-brown and can last much longer. Picking and squeezing spots, sun exposure and harsh treatments all make marks darker and slower to fade.
Red or purple marks are different: they come from small blood vessels, not pigment, and need a different approach. Pitted or raised areas are scars, covered on our acne scars page. For brown PIH, the first priority is controlling the acne itself, because treating marks while new breakouts keep forming is an uphill effort. After that, time, strict sun protection and gentle, well-chosen treatment do most of the work.
“If a dark mark is flat, it is pigment rather than a scar, and the gentlest treatment that works is the right one, because aggressive treatment can make PIH worse.”

What goes where
The honest ladder:
non-invasive first, medical when it is needed
At SkinRev Lab · non-invasive
Needleless SkinBooster — Brightening and hydrating boosters delivered without needles support a more even tone while marks fade. It helps shallow, recent brown marks; deeper grey-brown marks usually need medical care. Read more
HydraFacial Syndeo — Gentle cleansing and extraction reduce the congestion that leads to new breakouts and new marks, and hydration supports barrier recovery. It does not remove existing pigment directly. Read more
SKINLDM® — Dual-frequency micro-massage ultrasound aims to calm inflamed, reactive skin. Less inflammation means fewer triggers for new marks, which suits skin that is still breaking out. Read more
At IN Eternity Clinic · Dr Sin Yong
Laser Toning — Low-energy 1064 nm Q-switched Nd:YAG passes break down excess melanin gradually with little surface heat. It suits widespread marks in skin that darkens easily, using conservative settings. How it works
Pico Laser (T2 Frax Radiance) — Picosecond pulses break pigment into fine particles with less heat, and are used for stubborn brown or grey-brown marks once active acne is under control. How it works
Enquiries to SkinRev Lab about medical treatments are passed to IN Eternity Clinic, where Dr Sin Yong performs them.
Start non-invasive if your marks are recent, light brown and few, and your acne is mild and settling. Combine this with sunscreen every day and a firm hands-off rule for spots. See the doctor first if you still have active or cystic acne, since prescription treatment may be needed before the marks will clear; if marks are grey-brown or have lasted longer than six months; or if the skin is pitted or raised, which suggests scarring rather than pigment. If you have darkened after a previous laser or peel, tell Dr Sin Yong, so the plan at IN Eternity Clinic starts gently. Patience is part of the plan: even with good treatment, pigment clears over months rather than weeks.

What the research says
The evidence,
with sources
Acne-related PIH is common in Asia. A survey by the Asian Acne Board of 324 people attending dermatologists for acne in seven Asian countries found that more than half had PIH, that marks often lasted a year or longer, and that many found them as bothersome as the acne itself; picking was common and is a habit that can be changed (Abad-Casintahan et al.). A review of PIH in skin of colour recommends treating the underlying inflammation early, with daily sun protection and topical lightening agents first, and keeping procedures such as laser for resistant cases, used with caution (Davis and Callender).
A 2024 systematic review of 41 studies and 877 people found that complete clearance of PIH was uncommon with any method, although most people achieved partial improvement with lasers, topical agents or combinations, and a small number worsened after laser or energy-based treatment (Kashetsky et al.). A focused review of acne and procedure-related PIH in Asians makes the same point: lasers can help as an add-on or when topicals fail, but the treatment itself can worsen PIH if it is too aggressive (Eimpunth et al.).

Common questions
Your questions,
answered
Are acne marks the same as acne scars?
No. Acne marks are flat changes in colour: brown or grey-brown marks are pigment, while pink or purple marks come from small blood vessels. Acne scars are changes in texture, such as pits, rolling dips or raised bumps. Marks usually fade over time and respond to brightening or gentle laser, while scars need collagen-remodelling treatments. Many people have both, and they are treated differently.
What does acne marks removal in Singapore usually involve?
It starts with calming any active acne, because new spots keep creating new marks. Daily sunscreen and a hands-off rule follow. At SkinRev, brightening boosters and calming treatments support the skin while marks fade. For marks that persist, Dr Sin Yong at IN Eternity Clinic may use low-energy laser toning or a picosecond laser, with settings chosen to avoid triggering new darkening.
How much does acne marks removal in Singapore cost?
At SkinRev, the Needleless SkinBooster is S$288 per region, HydraFacial Syndeo is from S$288 per session and SKINLDM is S$288. Laser toning and pico laser are medical treatments, so pricing is given at consultation at IN Eternity Clinic, once Dr Sin Yong has checked whether the marks are pigment, redness or scarring and how widespread they are.
How long do acne marks take to fade on their own?
Light brown marks in the upper skin often fade over a few months, especially with good sun protection. Deeper grey-brown marks can last much longer. In a study of acne patients across seven Asian countries, marks lasted at least a year in more than half of those affected. Treatment aims to speed up fading and prevent new marks, rather than replace patience entirely.
Can laser make acne marks worse?
Yes, it can, which is why caution matters. Heat and inflammation from a laser can trigger new pigment, especially in skin that darkens easily. Reviews of PIH treatment report that a small number of people worsened after laser. To lower this risk, settings are kept conservative, sessions are spaced out, active acne is controlled first, and strict sun protection is used throughout.
What can I do at home to help acne marks fade?
Wear broad-spectrum sunscreen daily, even indoors near windows, because light keeps stimulating pigment. Avoid picking or squeezing spots. Use a gentle cleanser and moisturiser, and introduce brightening ingredients such as niacinamide or azelaic acid slowly to avoid irritation. Stop anything that stings or causes redness. If acne keeps flaring, see a doctor, because preventing new spots prevents new marks.
