Pigmentation — sun spots, melasma, post-inflammatory hyperpigmentation and uneven skin tone — is the most common skin concern among patients at Atelier Aesthetics. It is also one of the most frequently mistreated, because different pigmentation types respond to different treatments — and the wrong treatment can paradoxically worsen the condition.
Classifying Pigmentation Correctly
Solar lentigines (sun spots) are focal, well-defined superficial pigment from cumulative UV exposure — respond well to targeted laser. Melasma is diffuse, hormonally influenced pigmentation driven by basement membrane dysfunction — responds poorly to surface-only laser; FSX Laser LCLR® addresses the basement membrane mechanism. PIH is pigmentation following inflammation — responds to conservative laser and barrier support; high risk of recurrence with aggressive treatment in dark skin. Misidentifying the type is the most common clinical error.
The Risk of PIH in Asian Skin
Asian skin (Fitzpatrick types III–V) has a lower threshold for PIH — aggressive laser treatment that would be routine in lighter skin types can trigger significant darkening in Asian patients. The FSX Laser LCLR® — calibrated specifically for Asian skin and targeting the dermal mechanism — is particularly appropriate. Sun protection is a clinical requirement, not optional.
Treatment Hierarchy
For sun spots: R2 Glow Laser or PiQ picosecond laser — precise, targeted, minimal downtime. For melasma: FSX Laser LCLR® targeting basement membrane, combined with rigorous SPF 50+. For PIH: gentle approach with conservative laser and barrier support. For overall uneven tone: FSX Laser LCLR® addressing multiple pigmentation mechanisms simultaneously.

If pigmentation recurs consistently, the treatment is addressing the visible pigment without addressing the mechanism driving its production. For melasma, the basement membrane dysfunction needs to be addressed. For sun damage, ongoing UV exposure continues generating new pigment.
Yes — with correct laser parameters and wavelengths. The FSX Laser LCLR® is specifically designed for Asian skin. Aggressive ablative lasers not calibrated for Asian skin are contraindicated.
Sun spots may respond in 1–2 sessions; melasma requires a course with maintenance. Dr. Sin Yong will provide a realistic estimate at consultation.
Typically yes — most pigmentation laser treatments at Atelier Aesthetics allow normal activity including makeup within 24 hours.
Yes — retinol, tretinoin and other active topicals should be paused 3–5 days before and after most laser treatments.
