Pigmentation in Toronto & Markham: Treating Hyperpigmentation

No.「"Hyperpigmentation" is an umbrella term that encompassesMelasma, freckles, sunspots, PIH, friction-induced pigmentation, drug-induced pigmentationand several other subtypes. Melasma and freckles are subcategories of pigmentation, and their treatment plans are entirely different. The first step of Dr. Xu's protocol is always Wood's lamp + VISIA + medical history review — identify the subtype first, then decide on treatment.

Depends on the subtype.Sun spots / freckles / PIH can be substantially cleared(as long as triggers do not recur);Melasma and friction-induced pigmentation require long-term management,cannot be permanently cured in one go. The clinical goal isSignificant lightening + trigger removal + long-term stability。

Depends on subtype + skin type. ForSuperficial sunspots, overall dull skin toneEffective, but on Fitzpatrick III–V Asian skin it must beLow energy + test spot;For Melasma-type pigmentationis not recommended as a first-line option (due to high PIH rebound risk). Dr. Xu will decide whether to use IPL based on Wood's lamp subtyping.

Three common reasons for failure: (1) Subtype misdiagnosis —— treating melasma or PIH as ordinary pigment spots with high-energy IPL; (2) Energy overload —— Applying North American Caucasian parameters to Asian skin; (3) No pre-treatment performed —— Treating compromised skin barriers directly triggers PIH. Dr. Xu's protocol requires4 weeks of pre-treatment priming + test spot cannot be skipped.

Yes. The clinical name for acne marks is "Post-Inflammatory Hyperpigmentation (PIH)」,is one of the most common subtypes of hyperpigmentation. Treatment sequence:(1) Achieve thorough acne control first;(2) 4 weeks of barrier repair; (3) alternating ultra-low-energy PicoSure Pro + chemical peels. Skin tone typically normalizes after 4–6 sessions.

Yes, but it must be done withRemove the triggers first。This type of pigmentation is typically triggered by chronic friction (clothing, bra straps, rubbing). If the underlying cause isn't addressed, even repeated laser treatments will recur. First-line: Fotona ClearGlow 1064 nm + topical Cyspera, with visible results typically after 6–8 sessions. Adjustments to clothing and wearing habits are recommended.

By subtype:Sunspots / freckles: 1–3 sessions;PIH 4–6 sessions;Overall dullness: 5–8 sessions;Friction-induced pigmentation: 6–8 sessions;Combined / multi-subtype: 8–12 sessions. 1 session every 4–6 weeks. The exact number of sessions is determined by consultation assessment.

No.Hormones are highly active during pregnancy and breastfeeding. Any laser or topical brightening agent increases PIH risk while delivering poor results. We recommendPostpartum + at least 3 months after full weaningbefore starting evaluation. During this phase, use strict physical sun protection + barrier-repair skincare to prevent the pigmentation from worsening.

Cyspera ContainsCysteamine precursormedical-grade topical product — one of the very few Health Canada–licensed, non-hydroquinone topical regimens in North America with evidence-based efficacy for pigmentation. Dr. Xu uses it during the 4-week pre-treatment phase and throughout the long-term maintenance phase toTyrosinase inhibitionReduces new pigment formation and significantly lowers recurrence.

ID Cosmetic Clinic Located at 30 Gibson Dr., Markham — approximately 30–40 minutes from downtown Toronto, 20–25 minutes from North York, 15–20 minutes from Richmond Hill / Vaughan, and 20–30 minutes from Scarborough. At the junction of Highway 7 and 404 / 407.Pigmentation is typically a long-term treatment,Choosing a physician who can correctly classify your subtype matters more than distance — the cost of repeated mistreatment is far greater than a one-way commute.

「Pigmentation" is an umbrella term; clinically there are at least six subtypes:solar lentigines, ephelides, melasma, Hori's nevus, post-inflammatory hyperpigmentation (PIH), café-au-lait macules。Diagnostic requirement Wood's lamp Dark-room examination + VISIA multispectral quantitative analysis + medical history review diagnostic trio. Dr. Xu spends 30 minutes during consultation completing the subtype workup — only after classification can a treatment plan be finalized.

Depends on the subtype.Sunspots and freckles typically clear significantly within 1–2 sessions;Melasma, Hori's nevus, and PIH require 6–12 low-energy fractional sessions,and cannot be cured — only managed long-term. Any clinic promising "one-session cure for all pigmentation" warrants caution.

Depends on pigmentation subtype and Fitzpatrick level.IPL Effective for solar lentigines + superficial pigment + ruddy skin tone, but carries higher rebound pigmentation risk for melasma;PicoSure Pro / PicoWay Picosecond lasers are safer for nearly all pigmentation subtypes, especially suited for Asian Fitzpatrick III–V skin types。Dr. Xu selects based on subtype — there is no "which is better", only "which is right for you".

Three common reasons for failure: (1) Firing up the laser without subtyping —— treating melasma or PIH as solar lentigines with high-energy IPL; (2) Energy parameters copied directly from Caucasian North American templates —— Asian skin has 5–10× higher epidermal melanin content, so the same energy delivers an effective overload; (3) No test spot performed —— Treating the full face on the first visit makes localized repair impossible if rebound darkening occurs. This is PIH — rebound darkening is itself a form of pigmentation, and treatment must be paused while the barrier is restored before resuming.

Depends on subtype:Solar lentigines / age spots: 1–2 sessions((6-week intervals);Freckles: 1–2 sessions((6-week intervals);Epidermal melasma: 4–6 sessions((every 4–6 weeks);Hori's nevus / dermal type: 8–12 sessions((every 6 weeks);PIH 4–8 sessions((every 4–6 weeks);Mixed / refractory: 10–15 sessions(every 4–6 weeks).
