Hyperpigmentation Treatment Singapore
Hyperpigmentation Treatment Singapore
Hyperpigmentation is a broad term describing areas of skin that appear darker than the surrounding skin due to an excess of melanin – the pigment produced by specialised cells called melanocytes. It is one of the most common dermatological concerns across Singapore’s diverse population, and while it is rarely a medical emergency, it can significantly affect confidence and how people feel in their own skin.
Understanding the specific type of hyperpigmentation you have is essential, because the causes – and therefore the most effective treatments – differ considerably between subtypes.
Types of Hyperpigmentation
Post-inflammatory Hyperpigmentation (PIH)
Pigmentation that develops in the wake of skin inflammation or injury – most commonly following acne, eczema, insect bites, or procedures that disrupt the skin barrier. It is particularly prevalent and often more pronounced in medium to darker skin tones. PIH appears as flat, dark marks at sites of previous inflammation and tends to fade over time, though this process can take many months without targeted treatment.
Solar Lentigines (Sun Spots)
Well-defined, flat, brown macules that develop in areas of repeated sun exposure – the face, hands, forearms, and décolletage being the most common sites. They represent localised areas of accumulated UV damage and are distinct from freckles in that they persist year-round regardless of sun exposure.
Melasma
A hormonally influenced form of symmetrical facial pigmentation that requires its own specialist approach.
Freckles (Ephelides)
Genetically determined, small, flat, light-brown spots that typically appear on sun-exposed areas in those with fairer skin, and that tend to darken with sun exposure and fade in its absence.
Causes & Contributing Factors
UV Exposure
The most consistent driver across almost all forms of hyperpigmentation. UV radiation stimulates melanocyte activity as a protective response, leading to uneven melanin distribution over time – particularly in those with a history of significant cumulative sun exposure.
Inflammation
Any disruption to the skin – from acne, eczema, contact dermatitis, trauma, or procedures – can trigger post-inflammatory pigmentation, particularly in skin types III to VI.
Hormonal Influences
Oestrogen and progesterone sensitise melanocytes to UV stimulation, contributing to conditions such as melasma in hormonally susceptible individuals.
Genetics
Both the tendency to develop hyperpigmentation and the baseline distribution of melanin in the skin are influenced by genetic factors.
Treatment at Skincodes
Treatment selection depends on the type, depth, and extent of hyperpigmentation, as well as your skin type and how your skin has responded to previous treatments. Dr Ang will assess these factors carefully before recommending a course of action.
Topical Agents
Frequently the starting point for managing hyperpigmentation. Prescription formulations containing hydroquinone, retinoids, azelaic acid, tranexamic acid, niacinamide, or combination compounds work by regulating melanin production and accelerating the turnover of pigmented skin cells.
Chemical Peels
Improve skin tone and reduce surface pigmentation by promoting controlled exfoliation and cell renewal. The type and concentration of peel used are tailored to the pigmentation subtype and your skin’s tolerance.
Pico Laser (Deka Toro)
Uses ultra-short picosecond laser pulses to fragment melanin deposits with precision, stimulating the skin’s natural clearance mechanisms with minimal surrounding tissue disruption. It is effective for solar lentigines, PIH, and certain other pigmentation subtypes, and is well-suited to a range of skin tones.
What to Expect
Treatment is typically delivered across a series of sessions, with intervals that allow the skin to respond and recover. Progress is gradual.
An ongoing sun protection regimen is essential alongside all pigmentation treatments – without it, results will be temporary and pigmentation will recur.
Why Choose Specialist Surgical Care
Dermatological surgery performed by a specialist offers distinct advantages:
- Accurate pre-surgical diagnosis with dermoscopy. Lesions are assessed carefully as appearances can be
misleading without specialist evaluation - Appropriate margin assessment for cancer excisions based on lesion type and guidelines
- Histological analysis of all removed tissue to confirm diagnosis and clear margins
- Minimally invasive techniques selected to optimise cosmetic outcomes
- Structured follow-up and surveillance for ongoing skin health
