The test spot — your single best safety habit

Because reactive skin is unpredictable per individual, the most pigment-aware habit you can build is to test before you commit. A test spot — a small, discreet area treated at your intended settings — shows you how that person's skin responds before you treat a whole face or visible area.

Document it — and document the client's response to past procedures during intake. Prior reaction is one of your best predictors. The more reactive the skin and the more aggressive the treatment, the more a test spot stops being optional and becomes standard of care.

Chemical peels — conservative by design

Peels are one of the most useful tools for melanin-rich skin and one of the most common causes of professional-induced PIH when chosen poorly. The pigment-aware approach is superficial and conservative.

Pigment-aware peel practice: prime the skin where appropriate (a period of tyrosinase-inhibitor use before peeling lowers rebound-pigment risk), start at the lowest effective strength with fewer layers and shorter contact, and build over sessions rather than going hard once. Don't chase aggressive frosting in this population, and treat sun protection between and after peels as mandatory.

Lasers & light — the highest-stakes category

This is where melanin-rich skin demands the most respect. Melanin is a target (chromophore) for many laser and light wavelengths — so energy meant for hair or vessels can be absorbed by the skin's own pigment, causing burns, blistering, PIH, or hypopigmentation (pigment loss).

Settings matter as much as the device: lower fluence, longer pulse durations, and robust cooling reduce epidermal injury — and test spots are non-negotiable before any energy treatment on deep skin.

Microneedling, extractions & hair removal

Microneedling

• Can be appropriate for deeper skin — sometimes used for PIH or texture — but inflammation control is everything. Excessive depth or aggression risks PIH and tracking. Conservative depth, clean technique, calm aftercare, sun protection after.

Extractions

• Gentle, proper technique only. Forceful extraction is a classic, avoidable PIH trigger — don't over-work a lesion.

Hair removal

• Laser: same wavelength logic — Nd:YAG is generally preferred for deeper skin; the wrong device or settings risk burns and dyschromia.
• Waxing: trauma and friction can trigger PIH — use caution, and avoid waxing skin that's on retinoids or recently exfoliated.
• Threading / friction: same principle — minimize trauma.

Pre- and post-care — protecting the result

The procedure is only half the outcome; what surrounds it decides whether PIH shows up.

• Before: prime where appropriate, rule out contraindications, set realistic expectations, reinforce sun protection.
• After: gentle, barrier-supporting care; no picking; no extra actives that add inflammation; daily sun protection (the flashlight rule applies here too).
• Space out aggressive treatments. Stacking procedures compounds inflammation — a common way well-meaning professionals cause dyschromia.

Contraindications, red flags & scope

Pause or refer when you see:

• Recent isotretinoin — skin is more fragile; many procedures are contraindicated for a period after stopping.
• History of keloids or hypertrophic scarring — higher scarring risk; extra caution or refer.
• Active infection, open lesions, or uncontrolled skin disease in the area.
• Unrealistic expectations, or a request for treatment beyond what's safe for that skin.

When a safe result would require a device, depth, or prescription beyond your license, referral is the pigment-aware choice. Knowing the edge of your scope is a clinical skill.
