Melasma, pigmentation and dark marks: why the right assessment matters.

Patients often use the words pigmentation, melasma, sun spots and dark marks interchangeably. They can look similar in a mirror or photograph, but they do not necessarily have the same cause or require the same plan.

At Medify in Waterkloof, Pretoria, professional skin care is assessment-led. The aim is not to place every patient on the same brightening routine or move directly to a peel. It is to understand the pattern, likely trigger, skin condition and risk of making the pigmentation worse before treatment is selected.

“Pigmentation” describes a change—not one condition

Pigmentation means a visible change in skin colour. Hyperpigmentation refers to an area that has become darker because more melanin is being produced or deposited. That tells us what the skin is doing, but not why.

The American Academy of Dermatology notes that effective management of dark marks begins by finding the cause. If acne, eczema or irritation remains active, trying to fade the mark without controlling the trigger is unlikely to produce a stable result.

Why assessment comes before a product list

A useful skin assessment is not simply a sales conversation about ingredients. It should build a clinical and practical picture of the concern. Depending on the presentation, this may include:

• When the colour change began and whether it is stable or changing
• The distribution, symmetry, colour and border of the affected areas
• Acne, eczema, irritation, hair-removal practices or previous procedures
• Current skin-care products and any burning, stinging, peeling or sensitivity
• Sun and heat exposure, outdoor work, sport and light-protection habits
• Pregnancy, hormonal changes and relevant medicines
• Previous treatment, response and any rebound or worsening
• Skin tone and the individual risk of post-inflammatory pigmentation

The assessment may lead to a conservative skin-care plan, selected professional treatment, medical review or referral to a dermatologist. A consultation does not guarantee a peel, procedure or prescription.

When a dark spot should not be treated as a cosmetic mark

Aesthetic and skin-health treatment should pause when the diagnosis is uncertain. Arrange medical assessment for a spot or patch that is new and unusual, looks different from the others, changes in size, colour or shape, itches, bleeds, becomes painful or does not heal. The AAD specifically advises medical review for lesions that differ, change, itch or bleed.

This does not mean that every changing mark is dangerous. It means that a cosmetic treatment room is not the place to guess. At Medify, concerns outside the appropriate scope are medically assessed or referred.

Light protection is part of treatment, not an optional extra

Ultraviolet radiation can stimulate pigment and worsen photo-ageing. The World Health Organization recommends a combination of shade, protective clothing, a broad-brimmed hat and broad-spectrum sunscreen for protection from excessive UV exposure.

For melasma and some forms of hyperpigmentation, visible light may also matter. Dermatology guidance commonly includes a broad-spectrum sunscreen with SPF 30 or higher; a tinted formulation containing iron oxides may be considered where visible-light protection is relevant. Product choice still needs to suit the patient’s skin, daily routine and tolerance.

Sun protection is not a promise that pigmentation will disappear. It reduces an important ongoing stimulus and helps protect any improvement achieved through the rest of the plan.

Why more active ingredients are not always better

People frustrated by pigmentation often layer acids, scrubs, retinoids, brightening serums and spot treatments. The result may be irritation, barrier disruption and more post-inflammatory pigment—the opposite of the intended outcome.

A rational routine usually gives each product a clear job. It considers:

• Whether active inflammation must be controlled first
• Which single or limited combination of ingredients matches the diagnosis
• How often the product can be used without persistent irritation
• Pregnancy, breastfeeding, medicine use and other contraindications
• How progress and tolerability will be reviewed

Products obtained online or informally may also contain undeclared or unsuitable ingredients. Do not use household bleach or unlabelled “lightening” mixtures on the skin, and do not continue a product that causes significant burning, swelling or blistering.

Peels and procedures need diagnosis, timing and restraint

Chemical peels, microneedling and selected light or laser procedures may have a role for some patients. They are not interchangeable, and they are not automatically the first step.

Before a procedure, the practitioner should consider the suspected diagnosis, pigment depth, skin tone, recent sun exposure, active acne or dermatitis, history of scarring or pigment change, current medicines, prior procedures and the patient’s ability to follow aftercare. The AAD describes procedures as possible additions to an individual melasma plan, not universal stand-alone cures.

Starting with an aggressive procedure while the skin is inflamed or the trigger is uncontrolled can prolong recovery or deepen pigment. A staged plan may be slower on paper but safer and easier to assess.

Realistic timelines protect patients from overtreatment

Pigment changes gradually. The visible colour may sit at different depths, and the skin needs time to respond without repeated injury. Melasma in particular can be stubborn and recurrent. Professional guidance notes that improvement may take months rather than days.

Progress should therefore be judged with consistent photographs, stable lighting and agreed review points—not by changing the routine every week. A sensible plan also defines what would lead to stopping, simplifying or referring treatment.

How to prepare for a pigmentation consultation

• Bring or photograph every product currently used on the affected area.
• List medicines, supplements and previous prescription creams.
• Note when the pigment began and what happened before it appeared.
• Share previous peels, needling, laser or other procedures and how your skin reacted.
• Mention pregnancy, breastfeeding or plans for pregnancy where relevant.
• Do not deliberately tan or start several new active products before the visit.
• Bring earlier photographs if the pattern has changed over time.

Frequently asked questions

Is every dark facial patch melasma?

No. Dark marks may follow acne, eczema, irritation or injury; other patches may relate to sun exposure, medicines or another skin condition. A new, changing, bleeding, itching or non-healing lesion needs medical assessment rather than cosmetic treatment.

Can a chemical peel remove melasma permanently?

No procedure can promise permanent clearance. A peel may be considered for selected patients as part of a wider plan, but suitability, peel depth, skin tone, active inflammation and aftercare all matter. Melasma can recur, especially when triggers continue.

Why can pigmentation treatment take months?

Pigment may sit at different depths, and the cause may still be active. Treatment usually combines trigger control, consistent light protection and carefully selected topical or procedural care. Improvement is gradual and varies by diagnosis and individual response.

Does a skin consultation guarantee a peel or prescription?

No. The consultation is used to assess the concern and decide whether treatment, further medical assessment, referral or a simpler skin-care plan is the appropriate next step.

The Medify approach

Medify combines professional skin assessment with medical oversight when required. The somatology and dermal-aesthetics team works within the appropriate scope, and Dr Luhard provides medical assessment or coordinates referral when a diagnosis, medicine or concerning lesion requires it.

The goal is not to promise perfectly even skin or sell the largest routine. It is to choose a defensible plan, protect the skin barrier, set realistic expectations and review the response.

It is not a prescription or a guarantee that a product, peel or procedure is suitable. Treatment depends on examination, professional scope, individual risk, informed consent and lawful availability. Seek medical assessment for a new, changing, bleeding, itching, painful or non-healing lesion. No outcome can be guaranteed.
