Procedures that can harm brown & deeper skin tones

By Seoulma Editorial · April 2025 · 8 min read

Brown and deeper skin tones are often underrepresented in clinical trials — which means many mainstream skin procedures were designed without your melanin in mind. We break down what to avoid, what to approach carefully, and what's actually safe.

Key concept Fitzpatrick IV–VI skin has more active melanocytes. Any heat, trauma, or inflammation can trigger overproduction of melanin — causing dark patches, scarring, or permanent discolouration that can take years to resolve.
Understanding the risk

Post-inflammatory hyperpigmentation (PIH) is one of the most common skin concerns for deeper tones. When skin is damaged, it heals by producing excess pigment. Add in a higher genetic predisposition to keloid scarring, and many popular in-clinic treatments can do far more harm than good — especially in inexperienced hands.


PIH risk — triggers dark spots

Keloid / scarring risk

Burns or dyspigmentation

Generally well-tolerated
High risk — avoid Procedures to avoid or refuse without expert consultation
Burns
Ablative laser resurfacing
CO₂ and Er:YAG lasers remove entire skin layers. Very high risk of permanent hyper- or hypopigmentation on Fitzpatrick IV–VI skin. Often simply not appropriate for deeper tones.
PIH
IPL (intense pulsed light)
Broadband light cannot reliably distinguish between pigmented lesions and your skin's natural melanin — resulting in burns, dark patches, and uneven tone. Largely unsuitable for brown skin.
Keloid
Dermabrasion
Mechanical removal of the skin surface causes significant trauma. Elevated keloid formation and PIH risk makes this highly problematic for deeper tones.
PIH
Deep chemical peels (phenol)
Phenol peels destroy deeper skin layers and can permanently lighten treated areas relative to surrounding skin — a visible and lasting mismatch on deeper tones.
Burns
Cryotherapy (over large areas)
Freezing destroys melanocytes, often leaving permanent white patches. May be appropriate for a single isolated lesion, but never for skin rejuvenation or broad use on darker tones.
✦
Moderate risk — proceed carefully Only with a provider experienced in Fitzpatrick IV–VI
PIH
Nd:YAG laser (1064 nm)
The safest laser wavelength for darker tones — longer wavelength bypasses superficial melanin. Still carries PIH risk if settings are too aggressive or if cooling is inadequate.
PIH
Non-ablative fractional laser
Fraxel-style treatments stimulate collagen without full ablation. Risk is meaningfully lower than ablative approaches, but pre-treatment priming is essential.
PIH
TCA peels (30–50%)
Higher-concentration TCA can trigger rebound hyperpigmentation. Concentrations of 20% or below with proper preparation are significantly safer.
PIH
Microneedling RF
Radiofrequency microneedling is generally well-tolerated, but surface electrode contact can cause PIH if not properly insulated. Insulated-needle devices are preferable.
Keloid
Thread lifts
Wound response to sutures can trigger keloid formation — which is more common in people of African, South Asian, and East Asian descent. Discuss predisposition honestly with your provider.
Burns
Laser hair removal
Diode and alexandrite lasers target melanin and can burn brown skin. Nd:YAG (1064 nm) at correct settings is the only suitable option for Fitzpatrick IV–VI.
✦
Lower risk — generally safe Well-tolerated with proper pre- and post-care
Safer
Microneedling (no RF)
Creates controlled micro-injuries without heat. Stimulates collagen effectively across all skin tones. Post-procedure SPF is non-negotiable to prevent PIH during healing.
Safer
Superficial peels — mandelic, lactic, glycolic ≤20%
Mandelic acid is especially suitable for melanin-rich skin: its larger molecular size means slower, more even penetration with a lower inflammation response.
Safer
Hydrafacial / aqua peeling
Combines gentle mechanical exfoliation, extraction, and hydration. Low trauma with no meaningful downtime. A reliable option for maintaining skin health across all tones.
Safer
Dermal fillers (HA)
Hyaluronic acid fillers carry no specific pigmentation risk. Vascular occlusion risk applies equally to all skin tones — choose a qualified injector with anatomical expertise.

Prime before any procedure

For moderate-risk treatments, apply topical retinoids, azelaic acid (10–20%), or tranexamic acid for 4–6 weeks beforehand. This calms melanocyte activity and significantly reduces PIH risk during recovery.

Ask your provider the right questions

"How many clients with skin like mine have you treated with this?" and "What's your protocol if PIH occurs?" are non-negotiable questions. No clear answer is a clear sign to look elsewhere.

SPF is your post-procedure non-negotiable

UV exposure after any procedure dramatically amplifies PIH risk. Broad-spectrum SPF 50 every morning — regardless of indoor/outdoor plans — is the single most important aftercare step.

Your Fitzpatrick type matters within "brown skin"

Skin types IV, V, and VI carry meaningfully different risk profiles. A provider who treats all brown skin identically — or worse, who uses settings designed for type II–III — is not the right fit for you.
