Beyond the Buzzword: A Dermatologist’s Guide to Laser Skin Treatment

By Kayley Fitz,Pharmacist | EDERMA

Laser skin treatment is one of the most searched, most talked about, and most misunderstood categories in dermatology. Scroll through any beauty platform and you’ll find laser positioned as everything from a lunchtime glow-up to a last resort – often in the same breath, occasionally by the same account.

The reality is considerably more interesting, and considerably more nuanced. Laser is a clinical tool – one that, in the right hands and with the right technology, can address conditions that topical skincare simply cannot reach. The key phrase there is the right technology.

Dr Nivana Ramlachan’s specialist dermatology practice has just invested in the Fotona Starwalker MaQX Pro – one of the most advanced laser platforms currently available. This post explains what it is, what it does, who it’s for, and what your skin needs before and after treatment.

How laser skin treatment actually works

Laser delivers concentrated light energy into the skin at a precise wavelength. Depending on that wavelength, the energy is absorbed by different targets – melanin (pigment), water in skin tissue, or ink particles in the case of tattoos. The surrounding tissue is left largely untouched.

This precision is what separates laser from most topical treatments. A serum can improve the surface of the skin. Laser can stimulate collagen remodelling beneath it, break down pigmentation at its source, and target structures that creams simply cannot reach.

The machine matters enormously. The operator matters even more. Laser in a clinical dermatology setting – assessed and performed by a specialist — is a fundamentally different proposition to laser in an aesthetic salon. The difference lies in diagnostic accuracy, skin type assessment, and the ability to manage complications when they occur.

The Fotona Starwalker MaQX Pro – what makes it different

The Fotona Starwalker MaQX Pro is a Q-switched Nd:YAG laser – a technology that delivers extremely short, high-energy pulses of light with exceptional precision. In practical terms, this means the laser can target pigment, ink, and vascular structures with high accuracy while minimising thermal damage to surrounding tissue.

This matters particularly in the South African context. The platform’s multiple wavelength options make it suitable for a broader range of skin tones – including darker skin tones that have historically been at greater risk of post-inflammatory hyperpigmentation from laser treatments. Appropriate technology for diverse skin is not a nicety. It is a clinical necessity.

The Starwalker platform also offers MaQX (Multi-Aperture Q-switching) technology, which delivers more uniform energy distribution across the treatment area – improving both efficacy and safety compared to older Q-switched systems.

What it treats

1. Skin Rejuvenation

Skin rejuvenation with the Starwalker works by delivering controlled laser energy into the deeper layers of the skin, stimulating the body’s natural collagen and elastin production. The result, over a series of treatments, is firmer, more even-toned, and more luminous skin – not because anything has been added, but because the skin has been prompted to repair and renew itself.

Most patients require a series of sessions spaced several weeks apart, with visible improvement typically developing gradually as collagen remodelling progresses.

2. Scar Treatment

Acne scars, surgical scars, and textural irregularities are among the concerns most commonly brought to Dr Nivana’s practice – and among the most undertreated, because most topical products cannot meaningfully address structural changes in the skin.

Laser scar treatment works by targeting the scar tissue beneath the surface – disrupting the disorganised collagen that characterises scar formation and stimulating the production of new, more organised collagen in its place. Over multiple sessions, this remodelling process can significantly improve the texture, tone, and appearance of scarred skin.

The number of sessions required depends on the type, age, and depth of the scar.

3. Tattoo Removal

Q-switched laser technology is the gold standard for tattoo removal, and the Fotona Starwalker MaQX Pro represents one of the most capable platforms available for this purpose. The laser delivers ultra-short pulses of energy that shatter ink particles into fragments small enough for the body’s immune system to clear naturally over time.

Several factors influence the outcome and number of sessions required: the age and depth of the tattoo, the colours present (darker inks respond more readily than lighter ones), the density of the ink, and your skin’s own immune response. Multiple sessions are always required – typically spaced six to eight weeks apart to allow the body time to clear the fragmented ink between treatments.

4. Melasma Treatment

Melasma is one of the most common and most challenging pigmentation conditions – particularly in South Africa, where high UV exposure creates ideal conditions for its development and recurrence. It presents as symmetrical patches of brown or grey-brown pigmentation, typically on the face, and is strongly influenced by hormonal factors, sun exposure, and genetic predisposition.

Laser can be an effective component of melasma treatment, but it is important to be clear: melasma is a chronic condition that requires a comprehensive management approach rather than a single-modality fix. At Dr Nivana’s practice, laser for melasma is used as part of a structured treatment plan that typically includes topical agents, strict photoprotection, and ongoing monitoring. The goal is meaningful, sustained improvement – not a promise of permanent resolution.

A thorough dermatological assessment prior to laser treatment for melasma is essential, as the wrong protocol or energy settings can worsen pigmentation rather than improve it. This is precisely why specialist oversight matters.

5. Solar Lentigo (Sun Spots)

Solar lentigines – commonly known as sun spots or age spots – are flat, darkened areas of skin that develop in response to cumulative UV exposure over time. They are among the most common skin concerns in the South African population and one of the most effectively treated with Q-switched laser technology.

Unlike melasma, which is driven by deeper, more complex pigmentary mechanisms, solar lentigines respond well to targeted laser treatment – often with visible improvement after a small number of sessions. The laser energy is absorbed by the melanin in the lentigo, breaking down the concentrated pigment which then clears naturally as the skin heals.

It is worth noting that any new or changing pigmented lesion on the skin should be assessed by a dermatologist before laser treatment is considered, to rule out anything that requires a different clinical approach.

Post-treatment care – what your skin needs after laser

Post-laser skin is in a state of active recovery. The treatment has deliberately disrupted skin structures – stimulating repair, clearing pigment, or remodelling collagen – and the skin needs specific support to heal well and maintain results.

Post-treatment skincare is part of the clinical protocol. Using the wrong products – or ignoring this phase entirely – can compromise your results and increase the risk of complications including post-inflammatory hyperpigmentation.

Barrier repair and soothing – immediate priority

Immediately post-treatment, the skin’s barrier is compromised and needs gentle, targeted support.

La Roche Posay Cicaplast and Eucerin Aquaphor skin balm is specifically indicated for post-procedure skin – providing barrier repair, antibacterial protection, and soothing support in a single formulation. Available through EDERMA.

Bioderma Sensibio foaming cleanser is appropriate for gentle cleansing during the healing phase, avoiding anything stripping or active.

SPF – non-negotiable

If there is one product that is absolutely non-negotiable post-laser, it is a broad-spectrum SPF50+. Laser-treated skin is significantly more photosensitive than normal skin – UV exposure during the healing phase can trigger post-inflammatory hyperpigmentation, undoing the results of treatment and potentially worsening existing pigmentation conditions.

This is not a suggestion. It is a clinical requirement – particularly in South Africa’s UV environment.

La Roche-Posay Anthelios and Heliocare pigmentation solution for pigmented skin – both available through EDERMA – are appropriate for post-laser skin. Fragrance-free, dermatologist-tested formulations that sit well on sensitised skin without causing additional reactivity.

Maintaining results – for melasma and solar lentigo patients

Once the skin has healed fully, maintaining the results of pigmentation treatment requires ongoing topical support. Vitamin C, niacinamide, and well-formulated brightening serums used consistently – and always under SPF – help suppress melanin overproduction and maintain the evenness achieved through treatment.

The specific products appropriate for your skin will depend on your skin type, your treatment protocol, and your tolerance for actives – which is exactly why a personalised recommendation matters more than a generic shortlist.

Is laser right for you?

Laser is not appropriate for every skin concern, every skin type, or every stage of a condition. It is a clinical tool – powerful, precise, and most effective when selected as part of a considered treatment plan rather than as a standalone quick fix.

The right starting point – before committing to any laser treatment – is a proper skin assessment by someone qualified to determine what your skin actually needs. That might be laser. It might be a topical treatment plan. It might be a combination of both, sequenced correctly.

Through EDERMA, you can access a free skin assessment conducted by a qualified somatologist working within Dr Nivana’s specialist dermatology practice. If your concerns are appropriate for laser treatment, you’ll receive a direct referral and recommendation – without the months-long wait for a standard specialist appointment.
