Condition · Fitzpatrick IV to VI · Battersea SW11
Neck pigmentation in Skin of Colour, in Battersea.
Healthy skin for every tone. Darkening on the neck in Fitzpatrick IV to VI skin is not a single condition. Post-inflammatory hyperpigmentation, frictional melanosis, acanthosis nigricans, and melasma extending from the face all present differently and need different treatment. At Melatone in Battersea, every neck pigmentation consultation begins with cause identification and a Fitzpatrick assessment before any in-clinic treatment is proposed.
A personalised consultation with Arman Zaki, GMC-registered Physician Associate (Ref A8131967). We even tone. We do not lighten complexion. We do not offer skin-whitening or skin-bleaching protocols.
What causes it
Cause first. Then treatment.
Neck darkening in people with Fitzpatrick IV to VI skin commonly reflects one of four patterns: post-inflammatory hyperpigmentation following acne or folliculitis, frictional melanosis from mechanical friction, acanthosis nigricans associated with systemic factors, or melasma extending from the face. Distinguishing them is the first job of any consultation, because they respond to different treatment ladders. Treating the wrong cause may worsen pigmentation.
Differential diagnosis
Other conditions that can look similar.
Each of the following may present similarly to the others; a clinical assessment distinguishes them.
- Post-inflammatory hyperpigmentation (PIH)
- Pigmentation that follows a prior skin injury or inflammatory event such as acne, folliculitis, heat rash, or low-grade friction. Distribution follows the original inflammation. The most common cause of neck darkening in Fitzpatrick IV to VI.
- Frictional melanosis
- Repeated mechanical friction (tight collars, jewellery, head-rest contact) combined with heat may produce linear or diffuse darkening along the friction zone. Evidence suggests reducing the friction source and supporting skin barrier repair may reduce visible pigmentation over months.
- Acanthosis nigricans
- Velvety, hyperpigmented thickening most commonly at the posterior neck and axillary folds. Associated with insulin resistance, endocrine conditions, and certain medications. Systemic evaluation by a GP is the appropriate first step before any aesthetic intervention. Evidence: Phiske MM (2014), Indian Dermatology Online Journal, DOI 10.4103/2229-5178.137765.
- Melasma extending from the face
- Hormonally and UV-driven. May extend from the cheeks and forehead onto the lateral neck. Symmetrical pattern, no prior local inflammatory trigger. See our melasma treatment page for the dedicated protocol.
The treatment ladder
What we may use, in order.
Each rung is added cautiously after the one below it is working. Not every patient receives every rung. Your plan is built at consultation.
-
Daily mineral SPF 50+ with visible-light coverage.
The single intervention with consistent evidence for preventing post-inflammatory hyperpigmentation in skin of colour. Tinted mineral formulations with iron oxides may attenuate UVA1 and visible-light driven melanogenesis. Daily reapplication is non-negotiable, including indoors. Evidence: Mar K. et al. (2025), Australasian Journal of Dermatology, DOI 10.1111/ajd.14432.
-
Topical pigment regulators.
Azelaic acid, tranexamic acid, niacinamide. Applied daily, foundational to every protocol. Hydroquinone is prescribed only where appropriate and is contraindicated in pregnancy.
-
Low-strength superficial chemical peels.
Mandelic acid or lactic acid formulations applied conservatively. High-concentration peels (including salicylic acid for this indication) carry a documented hyperpigmentation risk in Fitzpatrick V and VI and are not used for neck pigmentation at Melatone. Evidence: Mar K. et al. (2024) systematic review.
-
Polynucleotide biostimulator injections.
A regenerative skin-quality adjunct that may support skin barrier repair and hydration in pigmented skin. Mechanism is supported in the literature; condition-specific evidence in Fitzpatrick IV to VI is preliminary. We frame polynucleotides as adjunctive, not first-line for pigmentation alone. Evidence: Lampridou et al. (2025), Journal of Cosmetic Dermatology, DOI 10.1111/jocd.16721.
-
Microneedling with serum infusion, melanin-safe parameters.
Conservative pass numbers and short needle depths only, applied after the cause is controlled and no active inflammation is present. Evidence is stronger for textural concerns and acne scarring than for pigmentation per se; we use microneedling as adjunctive for skin quality alongside the pigmentation programme.
One of five professional infusion serums is selected at consultation based on your skin's primary concern. Each serum supports a different mechanism alongside the microchannel delivery.
- Brightening serum. Tranexamic acid, niacinamide, glutathione, and vitamin C. Selected for post-inflammatory pigmentation, hyperpigmentation, and uneven tone in Fitzpatrick IV to VI. May support brighter, more even-toned skin over a course of sessions. Results may vary.
- Regenerative serum. Polynucleotides (PDRN, salmon-derived sodium DNA), multi-peptide complex, and niacinamide. May support skin density, elasticity, and post-treatment recovery, particularly for ageing or fragile skin.
- Skin quality serum. Niacinamide, vitamin C, polynucleotides, vitamin B12, and a 25-peptide complex. Selected when the priority is overall texture, tone, and post-treatment recovery.
- Smoothing peptide serum. A multi-peptide complex with sodium DNA, niacinamide, and vitamin B12. Selected when the priority is the appearance of fine expression lines and surface texture. May support a smoother surface appearance.
- Hydrating serum. Hyaluronic acid. Selected for hydration, plumpness, and barrier support.
-
Low-fluence 1064 nm Q-switched Nd:YAG laser, selectively.
The most-studied laser for post-inflammatory hyperpigmentation in skin of colour. In a 2024 systematic review of 1,356 patients with PIH in darker skin, low-fluence 1064 nm Nd:YAG was the only intervention to achieve complete resolution in a subgroup (26 percent). Where laser is appropriate at Melatone for neck pigmentation, it is the 1064 nm wavelength at conservative low fluence after Fitzpatrick assessment and patch test, never as first-line. Evidence: Mar et al. (2024), Journal of Cutaneous Medicine and Surgery, DOI 10.1177/12034754241265716.
What we usually do not lead with
For neck pigmentation in Fitzpatrick V to VI, we do not lead with these.
Repeated procedural interventions in Fitzpatrick IV to VI carry an 11 to 17 percent rate of inducing post-inflammatory hyperpigmentation per systematic review evidence. The following are not first-line at Melatone for this indication:
- Skin-whitening, bleaching, or depigmentation creams. We do not stock, prescribe, or signpost to these.
- IPL pigment-removal protocols on Fitzpatrick V to VI necks.
- Aggressive Q-switched laser settings for general pigmentation.
- Medium-depth or deep chemical peels on neck skin in darker types.
- Single-session "miracle" device treatments without a topical foundation and sun-protection baseline.
- Hydroquinone for unsupervised at-home use.
Where low-fluence 1064 nm Nd:YAG is considered, it is only after topicals and conservative peels have been tried, after a patch test, and only where the risk-benefit profile is clearly favourable. The default at Melatone is conservative, not aggressive.

Questions, answered honestly
Before you book.
What causes darkening on the neck in darker skin tones?
Neck darkening in people with Fitzpatrick IV to VI skin may have several causes. Post-inflammatory hyperpigmentation following acne, friction, or heat is the most common. Other causes include acanthosis nigricans (often associated with insulin resistance), frictional melanosis from mechanical rubbing, and melasma extending from the face. A clinical assessment is required to distinguish between them; each has a different treatment pathway.
Could the darkening on my neck be acanthosis nigricans?
Acanthosis nigricans typically presents as velvety, hyperpigmented thickening at flexural areas, most commonly the posterior neck and axillae. It is associated with insulin resistance, certain endocrine conditions, and specific medications. If acanthosis nigricans is suspected, evaluation by a GP is the appropriate first step. Melatone may support the cosmetic appearance once a systemic cause has been assessed and managed. Evidence: Phiske MM (2014), DOI 10.4103/2229-5178.137765.
What is frictional melanosis and can it be treated?
Frictional melanosis on the neck may result from repeated mechanical friction (tight collars, jewellery, head-rest contact) combined with heat. Evidence suggests reducing the mechanical trigger and supporting skin barrier repair may reduce visible pigmentation over months. Treatment is selected based on cause and Fitzpatrick type at Melatone. Results may vary.
Which treatments are safe for neck pigmentation on Fitzpatrick V or VI skin?
For Fitzpatrick V and VI skin, the Melatone approach may include a structured topical programme (azelaic acid, tranexamic acid, niacinamide, mineral SPF 50+), low-strength mandelic or lactic acid peels, polynucleotide biostimulator injections as a barrier and skin-quality adjunct, and microneedling with melanin-safe parameters where indicated. Where laser is appropriate, low-fluence 1064 nm Q-switched Nd:YAG is the most-studied option in skin of colour. Aggressive lasers and high-concentration peels carry a documented risk of worsening pigmentation in darker skin and are not the starting point. Results may vary.
Does Melatone offer skin bleaching or whitening for neck pigmentation?
No. Melatone does not offer skin-whitening, bleaching, or depigmentation treatments. The clinic's clinical position is healthy skin for every tone, we even tone, we do not lighten complexion. Every protocol is designed to calm inflammation and correct uneven pigmentation while protecting the patient's natural skin tone.
