The Science of Beauty

Understanding Hyperpigmentation

Hyperpigmentation is one of the most common skin concerns our clients bring to us and one of the most misunderstood. The term covers a range of conditions that all share one thing in common: patches of skin that appear darker than the surrounding tone because of an excess of melanin, the pigment that gives skin its colour.

Melanin is produced by cells called melanocytes. When those cells are triggered by sun exposure, hormonal changes, inflammation, or injury, they can overproduce melanin in concentrated areas. The result is the spots, patches, and uneven tone that many clients have spent years trying to address with topical products alone.

The challenge with hyperpigmentation is that different types have different causes and sit at different depths within the skin. A treatment that works well for a surface-level sun spot may not be appropriate for deeper or more complex pigmentation. This is exactly why our team starts every pigmentation consultation with a thorough skin assessment to understand what type of pigmentation you have before recommending a treatment plan.

“Not all pigmentation is the same. Getting the assessment right is as important as the treatment itself.”

The Causes

What Causes Brown Spots and Uneven Skin Tone?

Hyperpigmentation is rarely caused by a single factor. Understanding what triggered yours helps our team choose the right approach for your skin.

Sun Exposure

Ultraviolet light is the most common trigger for visible pigmentation. Over time, UV exposure causes melanocytes to produce pigment unevenly, leading to the spots and patches that typically appear on areas most exposed to the sun the face, hands, shoulders, chest, and forearms.

Hormonal Changes

Hormonal shifts, particularly during pregnancy, while taking oral contraceptives, or during perimenopause, can trigger overproduction of melanin in the skin. This type of pigmentation, often called melasma, typically appears as larger, more diffuse patches across the cheeks, forehead, or upper lip.

Post-Inflammatory Response

After any injury, irritation, or inflammatory skin condition including acne, eczema, or even a reaction to a skincare ingredient the skin can produce excess melanin in the affected area as part of its healing process. This is known as post-inflammatory hyperpigmentation.

Ageing

As the skin ages, melanin production can become less regulated. Age spots and accumulated sun damage become more pronounced, and the skin’s natural cell turnover slows, making existing pigmentation more visible.

The Treatment

How Laser Treatment Targets Pigmentation

Laser treatment for hyperpigmentation works through a process called selective photothermolysis. Laser energy is emitted at a specific wavelength that is preferentially absorbed by melanin the pigment responsible for brown spots and uneven tone. The energy heats the pigmented cells, breaking them down without damaging the surrounding skin tissue. The body then naturally clears the treated pigment over the following days and weeks, gradually revealing clearer, more even skin.

The wavelength used matters significantly. Different types of pigmentation sit at different depths within the skin, and different wavelengths penetrate to different depths. This is why using a single, non-adjustable setting on every client is not an evidence-based approach.

At DermEsthetics, our laser treatments are performed using the GentleMax Pro by Candela Medical with a 755nm Alexandrite laser, an advanced platform designed to precisely target excess melanin responsible for sun spots, freckles, and other suitable pigmented lesions. This wavelength is highly effective for appropriately selected clients with Fitzpatrick skin types I–IV. Every treatment begins with a thorough consultation to assess your skin type, pigmentation concern, and suitability before any treatment is recommended. Integrated cooling technology helps keep each session comfortable by delivering a protective burst of cooling before every laser pulse.

The key word across all of this is precision. Our team does not guess. Every setting is chosen based on your skin type, the type and depth of your pigmentation, and the specific area being treated.

Laser Energy Delivered

A specific wavelength is emitted at the skin surface, calibrated to your skin tone and pigmentation type.

Melanin Absorbs Energy

The melanin in the pigmented cells absorbs the energy preferentially, breaking down the pigment while surrounding tissue remains unaffected.

Body Clears Treated Pigment

Over days and weeks, the body naturally removes the fragmented pigment, progressively revealing clearer, more even skin.

What We Treat

Pigmentation Concerns Our Team Treats

Our laser treatments address a range of pigmentation concerns. Find the one that sounds most like yours, or scroll through all six.

Sun Spots (Solar Lentigines)

Sun Spots

Flat brown patches on sun-exposed areas face, hands, shoulders, and chest.

Surface-level and responsive to laser. Energy targets and breaks down the concentrated melanin, which the body then clears naturally.

Typical results: Visible fading within 1-2 weeks per session. Course of 2-4 sessions recommended.

Age Spots

Brown or tan spots that become more pronounced from the mid-30s onward typically on the face, hands, and forearms.

Epidermal lesions that respond reliably to laser. Our team assesses depth and distribution before recommending a plan.

Typical results: Progressive lightening over 2-4 sessions.

Freckles

Small concentrated spots of melanin, most common in lighter skin tones. More visible in summer, often fading in winter.

Among the most responsive concerns to laser. Many clients choose to reduce rather than fully eliminate we follow your preference.

Typical results: Significant lightening after 1-3 sessions.

Post-Inflammatory Hyperpigmentation

PIH (Dark Marks from Acne)

Dark marks left after inflammation most commonly acne. Can persist for months or years without treatment.

More complex than surface spots. Laser requires careful calibration, particularly for medium to darker skin tones. Our approach is always conservative.

Typical results: Gradual improvement over several sessions; timelines vary by depth and skin tone.

Not appropriate for every candidate our team confirms suitability at consultation.

Melasma

Larger, diffuse patches of brown or greyish-brown tone across the cheeks, forehead, or upper lip often hormone-related.

The most complex concern we treat. Laser is not a universal solution here it helps in carefully selected cases with strict sun protection throughout.

Typical results: Gradual improvement where laser is deemed appropriate, across a carefully managed course.

Requires thorough assessment before any plan is confirmed. Not every client is a suitable candidate.

Diffuse Sun Damage

Uneven tone across larger areas face, neck, chest, forearms. Skin often looks dull or tired rather than showing discrete spots.

Laser works across the whole affected area, progressively improving evenness, clarity, and vitality rather than targeting individual marks.

Typical results: Visible improvement in tone and clarity over a course of 3-5 sessions.

Why Clients Choose Laser

Benefits of Laser Pigmentation Treatment

Targets Pigment at the Source

Rather than attempting to fade pigmentation at the surface, laser energy reaches the melanin responsible for discolouration and addresses it directly.

Precise and Controlled

Every session is calibrated to your skin type and pigmentation concern. Our team does not apply a generic setting -- the parameters are chosen specifically for you.

No Downtime for Most Clients

Most clients return to their normal routine immediately after treatment. Mild redness in the treated area typically settles within a few hours.

Safe for Suitable Skin Types

Every treatment starts with a skin assessment to ensure the 755nm Alexandrite laser is safe and suitable for your skin type and pigmentation concern.

Gradual, Natural-Looking Results

Pigmentation fades progressively as the body clears the treated cells -- so results look natural, not like an overnight change.

Complements Your Existing Skincare

Laser treatment works well alongside a well-chosen topical skincare routine. Our team can advise on what to use before and after sessions to support your results.

The DermEsthetics Difference

Why Choose DermEsthetics for Pigmentation Treatment

Pigmentation treatment requires more clinical precision than almost any other aesthetic service. The wrong wavelength, the wrong setting, or a missed contraindication can result in worsened pigmentation rather than improved skin which is exactly why the expertise of the team delivering your treatment matters as much as the technology they use. At DermEsthetics, our pigmentation treatments are performed by a team of trained, credentialed specialists working to protocols established under the clinical oversight of Dr. Sadia Tarar, MBBS, our founder and clinical director with over 25 years of combined medical and aesthetics experience.

Thorough Assessment First

We assess your skin type, pigmentation type, and treatment history before recommending anything. If a treatment is not right for you, we will tell you -- and recommend something that is.

Evidence-Based, Honestly Discussed

We do not overpromise on results or timelines. Our clients trust us because we tell them what to realistically expect before they book, not after.

A Team Trained to One Standard

Every specialist who performs your treatment has been trained and credentialed to DermEsthetics' clinical protocols. Your care is consistent at every visit.

What to Expect

Your Treatment Experience at DermEsthetics

Consultation

Your appointment begins with a conversation about your skin, your concerns, and your goals. Our team will assess your pigmentation type, your skin tone (Fitzpatrick type), your treatment history, and any relevant health background before recommending a plan -- with realistic timelines and honest expectations. No treatment proceeds without your full understanding and agreement.

Preparing for Treatment

Your specialist calibrates the laser to the correct wavelength and settings for your skin. During the session, you will feel a brief, warm snapping sensation with each pulse, kept comfortable by built-in cooling technology. Most sessions take 20 to 45 minutes depending on the area being treated.

Immediately After

Treated spots may temporarily appear darker in the hours or days following your session -- this is a normal and expected response as the fragmented pigment moves toward the surface before being cleared by the body. Mild redness typically settles within a few hours.

Aftercare

Your specialist will walk you through your aftercare at the end of every session. The most important steps are simple: protect the treated area from sun exposure diligently, keep your skincare routine gentle for the first few days, and avoid active ingredients until your skin has settled.

Realistic Expectations

Results and Timeline

Results vary depending on the type and depth of your pigmentation, your skin tone, the number of sessions completed, and how diligently you protect the skin from sun exposure between and after treatments. We will set your expectations honestly at your consultation.

Days After Each Session

Treated pigmentation often appears temporarily darker before it begins to fade. This is normal and expected -- a sign the treatment is working as intended.

Weeks 1-2 After Each Session

For surface-level pigmentation such as sun spots, freckles, and age spots, visible fading typically begins within the first two weeks after each treatment.

After a Full Course

Most clients see the most significant improvement after completing their recommended course. Sun spots, freckles, and age spots typically respond within 2-4 sessions. PIH and melasma may require more sessions with more variable results.

With Maintenance and SPF

Results are best maintained with consistent sun protection and, for some clients, periodic maintenance sessions. Without adequate sun protection, pigmentation can and will return -- our team will be clear about this at consultation.

Results vary by individual skin type, health history, consistency with the recommended schedule, and proper aftercare. Consult with our team for a personalized assessment before beginning any treatment.

Is This Treatment Right for You?

Suitable Candidates for Laser Pigmentation Treatment

Laser pigmentation treatment is suitable for many clients, but not all types of pigmentation respond to laser in the same way, and not every skin type is an appropriate candidate for every setting. Your consultation will confirm what is right for you specifically.

You May Be a Good Candidate If You Have

Sun spots, solar lentigines, age spots, or freckles you would like to reduce or remove.
Diffuse sun damage resulting in uneven skin tone across the face, neck, or chest.
Post-inflammatory dark marks from past acne or skin irritation (subject to assessment).
Brown patches consistent with melasma that have not responded to topical treatment alone (subject to thorough assessment).
Light to medium skin tones (Fitzpatrick I–IV) that are suitable for treatment with the 755nm Alexandrite laser.

This Treatment May Not Be Right If You

Have an active skin infection, open wound, or inflammatory condition in the treatment area
Are pregnant or breastfeeding
Have had very recent sun exposure or tanning (we recommend a minimum of 2-4 weeks of sun avoidance before treatment)
Have a history of keloid scarring
Are taking certain photosensitising medications (we will review this at consultation)
Have a pigmentation type or skin tone our team determines carries higher risk than benefit from laser at this time

Questions Answered

Frequently Asked Questions

What is hyperpigmentation?

Hyperpigmentation is a common skin condition where patches of skin appear darker than the surrounding area because of an excess of melanin. It covers a range of conditions, including sun spots, age spots, freckles, post-inflammatory dark marks, and melasma, each with slightly different causes and treatment considerations.

Can laser treatment permanently remove pigmentation?

For sun spots, age spots, and freckles, laser treatment can achieve significant, long-lasting results but results are not guaranteed to be permanent if the skin continues to be exposed to triggering factors, particularly UV radiation. Maintaining diligent daily sun protection is essential for preserving your results. For more complex pigmentation like melasma, results are more variable and ongoing management is often needed.

What laser technology does DermEsthetics use?

We use the GentleMax Pro by Candela Medical, a dual-wavelength laser platform with 755nm Alexandrite and 1064nm Nd:YAG wavelengths. This allows our team to select the most appropriate wavelength for your skin tone and pigmentation type, rather than applying a one-size-fits-all setting.

How many sessions will I need?

It depends on the type and depth of your pigmentation. Sun spots and freckles typically respond within 2-4 sessions. Diffuse sun damage may require 3-5. Post-inflammatory hyperpigmentation and melasma require individual assessment and more variable session numbers. Your specialist will give you a personalised recommendation at consultation.

Will treated pigmentation get darker before it fades?

Yes, and this is completely normal. In the days following treatment, pigmented areas often darken temporarily as the fragmented melanin moves toward the surface of the skin before being cleared by the body. This is a sign the treatment is working as intended.

Is there any downtime?

Most clients experience no downtime. You may have mild redness and temporary darkening of treated spots for a few days, but you can return to your normal daily activities right away. We recommend avoiding strenuous exercise and direct sun exposure for 48-72 hours after each session.

Is the treatment comfortable?

Yes. Most clients describe a brief warm or snapping sensation with each pulse. Our laser system has integrated cooling technology that protects the skin and keeps sessions comfortable throughout.

Is laser pigmentation treatment safe for darker skin tones?

It can be, but it requires careful assessment and precise calibration. Certain wavelengths are not appropriate for all skin tones, which is why our team assesses your Fitzpatrick skin type before any treatment. The 1064nm Nd:YAG wavelength on our laser system penetrates more deeply and is better suited to medium and darker skin tones where surface wavelengths carry higher risk. We will only recommend laser treatment if we are confident it is safe and appropriate for your specific skin.

Can you treat melasma with laser?

Melasma can be treated with laser in carefully selected cases, but it is complex, and laser is not appropriate for everyone with melasma. It requires thorough assessment, careful calibration, and a commitment to rigorous sun protection before, during, and after treatment. Our team will assess your melasma type, your skin tone, and your history and will be direct with you about whether laser is the right approach — or whether another path would serve you better.

Is post-inflammatory hyperpigmentation treatable with laser?

PIH can respond to laser treatment, but it is one of the more nuanced pigmentation concerns to manage, particularly in clients with medium to darker skin tones. Our team will assess your skin carefully before recommending laser for PIH and will be transparent about both the potential for improvement and the importance of careful approach.

How soon will I see results?

For surface-level pigmentation such as sun spots and freckles, many clients begin to see visible fading within 1-2 weeks of their first session. Improvement builds progressively with each additional session.

Can I wear makeup after my treatment?

We recommend keeping the treated area free of makeup for the first 24 hours after each session. After that, gentle makeup application is usually fine. Your specialist will give you specific guidance at the end of your appointment.

What happens if I don't protect the skin from the sun after treatment?

Without consistent sun protection, the skin is vulnerable to producing new melanin in the treated areas — meaning existing pigmentation can return and new pigmentation can form. SPF is not a recommendation, it is a requirement for maintaining your results. We will cover this in detail at consultation.

Can I combine this with other treatments at DermEsthetics?

Often yes. Our team will advise on how laser pigmentation sessions can be timed and sequenced alongside other treatments, such as facials or injectables, to complement rather than interfere with each other.
