Melasma Treatment Options: What Works Best?
A guide to understanding, treating, and preventing melasma using proven medical and natural approaches.
Melasma, a common skin condition causing dark patches on the face, can be a source of frustration for many individuals. This hyperpigmentation often appears on the forehead, cheeks, and upper lip, impacting self-esteem and prompting a search for effective treatments. While the exact melasma causes are not fully understood, factors such as sun exposure, hormonal changes, and genetics play significant roles in its development.
For those wondering how to get rid of melasma, various treatment options are available. From over-the-counter melasma treatment creams to professional interventions like laser treatment, the choices can be overwhelming. This article aims to explore the most effective melasma treatments, discussing first-line approaches, advanced therapies, and long-term management strategies. By examining what works best for different types and severities of melasma, readers will gain valuable insights to help them make informed decisions about their skincare journey.
Diagnosing Melasma
A dermatologist can often diagnose melasma through a clinical examination of the skin. This involves carefully examining the colour and distribution of the hyperpigmentation on the face, particularly on common areas like the forehead, cheeks, and upper lip.
Clinical examination
During the clinical examination, the dermatologist will assess the extent and severity of the melasma patches. They will note whether the hyperpigmentation appears as well-defined, dark brown macules (epidermal melasma) or as more diffuse, light brown to blue-grey patches (dermal melasma). The distribution pattern of the melasma, such as centrofacial, malar, or mandibular, will also be determined.
To aid in the diagnosis and evaluation of melasma, the dermatologist may use specialised tools like a Wood’s lamp or a dermatoscope. These devices allow for a more detailed assessment of the depth and characteristics of the pigmentation.
Wood’s lamp
A Wood’s lamp is a device that emits ultraviolet light, which can help differentiate between epidermal and dermal melasma. When the affected skin is examined under a Wood’s lamp, epidermal melasma will appear more pronounced, with accentuated borders. In contrast, dermal melasma will not show significant enhancement under the Wood’s lamp.
The Wood’s lamp examination is performed in a darkened room. The lamp is held about 10-30 cm away from the skin, and the dermatologist closely observes the appearance of the melasma patches under the ultraviolet light. This non-invasive test can provide valuable information about the depth of the pigmentation, which can guide treatment decisions.
Skin biopsy
In some cases, a skin biopsy may be performed to confirm the diagnosis of melasma or to rule out other potential causes of hyperpigmentation. During a skin biopsy, the dermatologist will remove a small sample of the affected skin using a special tool. The skin sample is then sent to a laboratory for microscopic examination.
Under the microscope, the pathologist will look for characteristic features of melasma, such as increased melanin pigment in the epidermis or dermis, the presence of melanophages (pigment-containing cells), and any signs of skin inflammation or damage. The biopsy results can help differentiate melasma from other conditions that may cause similar skin discoloration.
While a skin biopsy is not always necessary for diagnosing melasma, it can be a useful tool in certain situations. For example, if the appearance of the hyperpigmentation is atypical or if the patient has not responded to standard melasma treatments, a biopsy may be warranted to exclude other possible diagnoses.
Once the diagnosis of melasma is confirmed, the dermatologist will work with the patient to develop an individualised treatment plan. This may include a combination of sun protection measures, topical medications like hydroquinone or tretinoin, oral medications such as tranexamic acid, and in some cases, procedural treatments like chemical peels or laser therapy. The goal of treatment is to reduce the appearance of the hyperpigmentation and prevent further darkening of the skin.
First-Line Treatments
Topical medications
The mainstay of melasma treatment is topical medications that target the pigment-producing cells in the skin. Hydroquinone, a tyrosinase inhibitor, is considered the gold standard for treating
hyperpigmentation. It is available in concentrations ranging from 2% to 4% in over-the-counter products and up to 6% in prescription formulations. Hydroquinone works by inhibiting the conversion of DOPA to melanin, thus reducing the formation of new pigment. It is typically applied twice daily for a period of 3-6 months.
Other topical agents used in the treatment of melasma include azelaic acid, kojic acid, and vitamin C derivatives such as ascorbic acid and magnesium ascorbyl phosphate. These ingredients work through various mechanisms to reduce melanin production and promote a more even skin tone. Azelaic acid, for example, inhibits tyrosinase activity and has anti-inflammatory properties, while kojic acid chelates copper, a cofactor required for tyrosinase function.
Topical retinoids, such as tretinoin and adapalene, are also commonly used in melasma treatment. These vitamin A derivatives enhance cell turnover, leading to a faster shedding of hyperpigmented skin cells. They also inhibit tyrosinase transcription and reduce the transfer of melanosomes from melanocytes to keratinocytes. Retinoids are often combined with hydroquinone and a mild corticosteroid in a formulation known as the Kligman’s formula or triple combination cream.
Sun protection
Strict sun protection is crucial for the successful treatment of melasma and the prevention of relapse. UV radiation is a major trigger for melasma, as it stimulates melanocyte activity and increases pigment production. Patients should be advised to avoid direct sun exposure, especially during peak hours, and to wear protective clothing such as wide-brimmed hats and long-sleeved shirts.
The daily use of a broad-spectrum sunscreen with a sun protection factor (SPF) of at least 30 is essential. Sunscreens containing physical blockers like zinc oxide and titanium dioxide are preferred, as they provide protection against both UVA and UVB rays. Chemical sunscreens, which absorb UV radiation, can also be used, but may cause irritation in some individuals. Sunscreens should be applied liberally to all exposed areas, including the forehead, cheeks, nose, and upper lip, and reapplied every 2 hours or after swimming or sweating.
Skincare products
In addition to prescription medications and sun protection, over-the-counter skincare products can play a supportive role in the management of melasma. Gentle cleansers and moisturisers help maintain the skin barrier and reduce irritation, which can worsen hyperpigmentation. Products containing niacinamide, a form of vitamin B3, have been shown to inhibit melanosome transfer and improve skin tone evenness.
Antioxidants, such as vitamin E and ferulic acid, can help protect the skin from oxidative damage caused by UV radiation and environmental stressors. These ingredients are often found in serums and creams designed for hyperpigmentation-prone skin. When selecting skincare products, patients should look for non-comedogenic and fragrance-free formulations to minimise the risk of irritation and breakouts.
Second-Line Therapies
When topical treatments and sun protection fail to achieve the desired improvement in melasma, second-line therapies can be considered. These include chemical peels, microneedling, and laser treatments, which work by removing the excess pigment and stimulating skin renewal.
Chemical peels
Chemical peels involve the application of a chemical solution to the skin, causing controlled destruction of the epidermis and/or dermis, followed by regeneration and remodelling. Superficial peels, such as glycolic acid, salicylic acid, and lactic acid peels, are commonly used for melasma treatment. They work by increasing cell turnover, promoting the shedding of pigmented cells, and enhancing the penetration of topical lightening agents. A series of peels is usually required for optimal results, and maintenance treatments may be necessary to prevent recurrence.
Microneedling
Microneedling is a minimally invasive procedure that involves the use of a device with fine needles to create microscopic punctures in the skin. This triggers a wound-healing response, stimulating collagen production and skin remodelling. Microneedling can also enhance the absorption of topical lightening agents, making them more effective. A few sessions spaced several weeks apart are typically needed for best results. Potential side effects include temporary redness, swelling, and mild discomfort.
Laser treatments
Laser treatments for melasma work by selectively targeting the pigment in the skin, breaking it down into smaller fragments that can be absorbed and eliminated by the body. Q-switched lasers, such as the Q-switched Nd:YAG and Q-switched ruby lasers, are commonly used for this purpose. They deliver high-energy pulses of light in nanosecond durations, minimising thermal damage to surrounding tissues. Fractional lasers, which create microscopic columns of injury in the skin, can also be used to treat melasma. They stimulate collagen remodelling and skin renewal, leading to a more even skin tone.
Laser treatment for melasma requires careful patient selection and should be performed by experienced practitioners, as there is a risk of post-inflammatory hyperpigmentation, especially in darker skin types. A series of treatments is usually necessary, and maintenance therapy with topical agents and sun protection is crucial to prevent recurrence.
When considering second-line therapies for melasma, it’s essential to have realistic expectations and to understand that results may vary. A combination approach, incorporating topical treatments, sun protection, and second-line therapies, often yields the best outcomes. Consultation with a dermatologist can help determine the most appropriate treatment plan based on individual factors such as skin type, melasma severity, and treatment goals.
Managing Melasma Long-Term
Maintenance therapy
Maintenance therapy is crucial for preventing melasma recurrence and maintaining the improvements achieved through initial treatment. The goal is to continue suppressing melanin production and preventing the reactivation of melanocytes. Topical agents used in maintenance therapy typically include lower concentrations of hydroquinone, tretinoin, or other lightening ingredients such as kojic acid, azelaic acid, or vitamin C derivatives. These agents help to maintain an even skin tone and prevent the reappearance of hyperpigmentation.
The frequency and duration of maintenance therapy may vary depending on individual factors such as the severity of melasma, response to initial treatment, and the presence of triggering factors. A common approach is to gradually taper the frequency of application from daily use to two or three times per week. Regular follow-up with a dermatologist is essential to monitor the effectiveness of maintenance therapy and make adjustments as needed.
Preventing recurrence
Preventing melasma recurrence requires a comprehensive approach that addresses both internal and external factors. Sun protection remains the cornerstone of prevention, as UV exposure is a major trigger for melasma. Patients should be advised to use a broad-spectrum sunscreen with an SPF of at least 30 daily, even on cloudy days or when indoors. Wearing protective clothing, such as wide-brimmed hats and long-sleeved shirts, and seeking shade during peak sun hours can further reduce UV exposure.
Hormonal factors, such as pregnancy or the use of oral contraceptives, can also contribute to melasma recurrence. Women with a history of melasma may consider alternative forms of contraception or discuss the risks and benefits of hormonal therapies with their healthcare provider. Maintaining a balanced diet, managing stress, and avoiding skin irritants can also help prevent melasma flare-ups.
