Melasma is a common skin condition characterized by brown, gray, or tan patches that usually appear on the face, particularly on the cheeks, forehead, upper lip, and nose. It is caused by the overproduction of melanin, often triggered by factors like sun exposure, hormonal changes, genetics, or skin irritation. Treating melasma requires a multifaceted approach, as it can be persistent and challenging to manage.
Here is a detailed explanation of the procedure for Melasma Treatment in Dubai, including various treatment options, their effectiveness, and how they work.
Initial Diagnosis and Assessment
Before beginning treatment, a dermatologist or healthcare provider will:
Examine the skin: Identify the type of melasma (epidermal, dermal, or mixed) using tools like a Wood's lamp or dermatoscope.
Epidermal: Pigmentation is located in the upper layers of the skin and is more responsive to treatment.
Dermal: Pigmentation is deeper in the dermis and can be more difficult to treat.
Mixed: Combines both types and often requires a combination of treatments.
Identify triggers: Review medical history, lifestyle, sun exposure, hormonal factors (e.g., pregnancy, birth control pills), and skincare routines.
Set realistic expectations: Patients should understand that melasma is a chronic condition, and while treatment can reduce pigmentation, complete removal may not always be possible.
Sun Protection (Essential Step in Treatment)
Daily Use of Broad-Spectrum Sunscreen:
Sunscreen is critical as UV and visible light can worsen melasma.
Use a broad-spectrum sunscreen with SPF 30 or higher, containing physical blockers like zinc oxide or titanium dioxide.
Reapply sunscreen every two hours, especially when outdoors.
Avoid Sun Exposure:
Wear protective clothing, wide-brimmed hats, and sunglasses.
Seek shade and avoid peak sunlight hours (10 a.m. to 4 p.m.).
Use Tinted Sunscreens:
Tinted sunscreens containing iron oxide provide additional protection against visible light, which can also exacerbate melasma.
Topical Treatments
Topical treatments are the first-line therapy for melasma. These target pigment production and help lighten the affected areas.
a. Hydroquinone (HQ)
A gold standard treatment for melasma.
How it works: Inhibits melanin production by blocking the enzyme tyrosinase.
Application: Applied directly to dark spots once or twice daily for 8-12 weeks.
Side effects: Redness, irritation, or temporary skin lightening. Prolonged use (over 6 months) may lead to ochronosis (a rare skin condition).
b. Triple Combination Creams (TCC)
Contains hydroquinone, a corticosteroid, and tretinoin.
How it works: Combines melanin inhibition (HQ), anti-inflammatory effects (steroid), and skin renewal (tretinoin).
Effectiveness: Provides faster and more noticeable results compared to hydroquinone alone.
Common Brands: Tri-Luma, Kligman formula.
c. Other Pigment-Reducing Agents
Azelaic Acid:
Inhibits tyrosinase and has anti-inflammatory properties.
Safer for sensitive skin and pregnant women.
Kojic Acid:
A natural melanin inhibitor derived from fungi.
Often combined with other agents for enhanced effects.
Vitamin C (Ascorbic Acid):
An antioxidant that reduces melanin and promotes skin brightening.
Niacinamide:
Reduces pigment transfer from melanocytes to skin cells.
d. Retinoids
Include tretinoin, adapalene, or retinol.
How they work: Increase cell turnover, reducing pigment accumulation and improving skin texture.
Often used in combination with other treatments.
Chemical Peels
Chemical peels help exfoliate the skin and enhance the penetration of topical treatments.
Types of Peels:
Superficial peels like glycolic acid, salicylic acid, lactic acid, or mandelic acid are commonly used.
Jessner’s solution and trichloroacetic acid (TCA) peels can also be effective.
Procedure:
A dermatologist applies the peeling solution to the affected areas, which removes the outermost skin layer and stimulates cell turnover.
Frequency:
Typically done every 4-6 weeks, depending on the skin type and severity.
Benefits:
Reduces melanin in the epidermis and improves skin texture and tone.
Laser and Light-Based Treatments
Laser treatments are often used for stubborn or dermal melasma, but they should be performed cautiously as they can sometimes worsen pigmentation.
a. Q-Switched Lasers
Targets melanin in the dermis and epidermis.
Common types: Nd:YAG laser (1064 nm wavelength).
Delivered in low-energy sessions to prevent post-inflammatory hyperpigmentation (PIH).
b. Fractional Lasers
Fractional resurfacing lasers, like the Fraxel laser, target pigmentation while promoting collagen production and skin renewal.
Suitable for deeper pigmentation.
c. Intense Pulsed Light (IPL)
A non-laser treatment that uses broad-spectrum light to target pigmentation.
Works best for epidermal melasma.
Precautions with Lasers:
Lasers can sometimes trigger PIH, especially in darker skin types, so they should only be performed by experienced professionals.
Microneedling with Tranexamic Acid
How it works: Microneedling creates micro-injuries in the skin, allowing deeper penetration of tranexamic acid, which reduces melanin production and improves vascular components of melasma.
Benefits: Safe for all skin types and reduces the risk of PIH.
Oral Medications
a. Tranexamic Acid (TXA)
How it works: Reduces melanin production by inhibiting plasmin activity in the skin.
Often prescribed for stubborn cases or when topical treatments fail.
Side effects: Rare but may include gastrointestinal issues or blood clotting risks.
b. Antioxidants
Glutathione, polypodium leucotomos extract, or other antioxidants can reduce oxidative stress and prevent pigment formation.
Maintenance and Long-Term Management
Melasma is chronic, and maintenance is crucial to prevent recurrence.
Maintenance Treatments:
Continue sunscreen use and reapply regularly.
Use mild depigmenting agents or antioxidants as part of a daily skincare routine.
Avoid triggers:
Hormonal medications (if possible).
Heat exposure, which can worsen melasma.
Conclusion
Treating melasma requires a comprehensive and individualized approach. Combining sun protection, topical agents, chemical peels, and advanced procedures like lasers or microneedling can help reduce pigmentation. Results may take weeks to months, and maintenance therapy is essential to prevent recurrence. For best outcomes, treatment should always be guided by a dermatologist experienced in managing melasma.
