Pigmentation concerns, such as dark spots, melasma, sunspots and uneven skin tone, are among the most common reasons people seek aesthetic treatments in Singapore. While topical skincare can help to a certain degree, stubborn pigmentation often requires a more targeted and effective solution.
This is where laser treatment for pigmentation comes in. In this guide, we break down how these treatments work, what to expect and key things to consider before starting your pigmentation fading journey.
How Lasers Target Pigmentation
Modern lasers treat pigmentation by focusing precise pulses of light energy into the skin. The purpose is to break down excess melanin, the pigment responsible for dark spots, into smaller fragments that the body can gradually clear away.
Different types of pigmentation sit at different depths of the skin. For example:
- Sunspots and freckles are usually at the surface
- Melasma and deeper pigmentation sit further below the epidermis
Laser devices can be adjusted to target these layers appropriately. This makes laser treatment for pigmentation a preferred method, as the energy can be controlled with high accuracy, reducing the risk of unnecessary damage to surrounding tissue.
Pigmentation Usually Cannot Be Removed in One Session
Many patients hope for a one-session solution, but pigmentation rarely fades instantly.
Multiple factors affect how long the process takes, including:
- Type of pigmentation
- Depth and density of the pigment
- Duration (how long it has been present)
- Skin type and tone
Superficial spots may lighten in just a few sessions, while deeper concerns such as melasma typically require a longer, more gradual approach. Most patients require 3 to 6 sessions, although some may need more depending on the severity of the condition.
Laser sessions are typically spaced 3 to 4 weeks apart to allow the skin to heal and to monitor the response of the pigmentation. Managing expectations is important; pigmentation often fades progressively rather than disappearing overnight.
Some Discomfort and Downtime May Be Expected
Laser energy can create a prickling or warm sensation, depending on the device used and the intensity of the treatment. Most patients describe the feeling as tolerable, similar to a mild rubber band snap on the skin.
To minimise discomfort, clinics often use cooling devices, and topical numbing cream may be applied for higher-energy treatments.
Some redness, mild swelling or temporary darkening of the treated spots may occur after the session. This is part of the normal healing process as the pigmentation breaks down.
Sun Protection is Essential Before and After Treatment
Pigmentation is extremely sensitive to UV exposure. Even with treatment, sun exposure can worsen the condition or reverse progress.
Patients receiving laser treatment for pigmentation must use broad-spectrum sunscreen daily, avoid prolonged outdoor activity and wear hats or sun protective clothing where possible.
Proper sun protection helps stabilise results and prevent new pigmentation from forming.
A Doctor’s Evaluation is Crucial
Pigmentation is not a one-size-fits-all problem. Conditions such as melasma, postinflammatory hyperpigmentation, and sunspots all require different treatment approaches, and incorrect treatment may worsen pigmentation.
A proper medical evaluation helps determine
- The exact type of pigmentation
- Whether laser is suitable
- What treatment settings are appropriate
- Whether combination treatments are needed (e.g. chemical peels, skincare, medications)
Only a trained medical professional should perform laser treatment for pigmentation to ensure safety, correct diagnosis and optimal outcomes.
Managing Expectations for Results
Lasers can significantly lighten pigmentation, but results vary based on the condition. Some dark spots may fade almost completely, while deeper pigmentation may show improvement but not full removal.
A treatment plan may include → several laser sessions, topical creams to maintain results, regular sun protection and lifestyle adjustments (e.g. avoiding heat triggers for melasma) The best outcomes occur when patients commit to a long term management plan.
