Causes, Treatment Options and Long-Term Management of Facial Pigmentation
Melasma is a common pigmentation condition that presents as patchy brown or grey-brown discoloration on the face. It is more common in women and individuals with Asian or darker skin types.
While melasma is not harmful, it can be persistent and difficult to treat without the right approach.
At Stephanie Ho Dermatology, we focus on safe, long-term management of melasma, using a combination of medical, oral, and energy-based treatments tailored to your skin.
What is melasma?
Melasma typically appears on:
- cheeks
- forehead
- upper lip
- nose
- chin
It may also occur on sun-exposed areas such as the neck.
Unlike simple pigmentation, melasma often involves both superficial, deep and more complex pigment pathways, which is why it often recurs.
What causes melasma?
Melasma is triggered by multiple factors:
- Sun exposure (UV and visible light) — stimulates pigment-producing cells
- Hormonal changes — pregnancy, oral contraceptives, HRT
- Genetics — family history increases risk
- Heat and inflammation — can worsen pigmentation even without sun
Melasma is therefore best understood as a chronic, relapsing condition, not a one-time problem.
Treatment approach for melasma
Effective treatment requires a careful and conservative combination approach. Overly aggressive treatments can worsen pigmentation.
1. Sun protection (most important step)
Strict sun protection is essential for both treatment and prevention.
- broad-spectrum SPF 50+ daily
- physical sunscreens (zinc oxide / titanium dioxide)
- reapplication every 2–3 hours outdoors
- hats and sun avoidance
Visible light and heat protection are equally important.
2. Medical-grade topical treatments
Topical therapy forms the backbone of melasma treatment. Common options include:
- hydroquinone
- tretinoin
- azelaic acid
- kojic acid
For long-term or sensitive skin:
- cysteamine
- tranexamic acid creams
These work by:
- reducing melanin production
- increasing skin turnover
- gradually lightening pigmentation
3. Oral treatments
For more persistent melasma:
-
Oral tranexamic acid
- reduces pigment activation pathways
- effective in selected patients
-
Antioxidants (e.g. glutathione)
- support skin brightening and reduce oxidative stress
These are prescribed carefully under medical supervision.
4. Energy-based treatments (used cautiously)
Unlike other pigmentation, melasma must be treated carefully with devices.
Microneedling radiofrequency (RF)
- targets abnormal blood vessels and inflammation
- helps regulate pigment production
- improves skin quality and resilience
This is one of the safer device-based treatments for melasma.
Gentle pigment lasers
- low-fluence, low-energy treatments
- gradual lightening with minimal risk
Examples include:
- picosecond lasers
Aggressive lasers can worsen melasma and are avoided.
5. Chemical peels
Mild peels (e.g. mandelic acid, pyruvic acid):
- improve skin turnover
- support topical treatments
Used as part of a combination plan.
| Treatment step | What it involves |
|---|---|
| 1. Sun protection | Broad-spectrum SPF 50+ daily, physical sunscreens, reapplication every 2–3 hours outdoors, hats and sun avoidance |
| 2. Medical-grade topical treatments | Hydroquinone, tretinoin, azelaic acid, kojic acid; cysteamine and tranexamic acid creams for long-term or sensitive skin |
| 3. Oral treatments | Oral tranexamic acid and antioxidants such as glutathione, under medical supervision |
| 4. Energy-based treatments | Microneedling radiofrequency and gentle, low-fluence pigment lasers, used cautiously |
| 5. Chemical peels | Mild peels such as mandelic acid and pyruvic acid, as part of a combination plan |
What results can you expect?
- gradual improvement over months
- reduction in pigmentation intensity
- improved skin tone and clarity
Melasma is controlled, not cured. Maintenance treatment is usually required to prevent recurrence.
Long-term management of melasma
Successful management requires:
- consistent sun protection
- maintenance topical therapy
- avoidance of heat and skin irritation
- regular review with your dermatologist
Why expert care matters
Melasma is one of the most difficult pigmentation conditions to treat. Incorrect or aggressive treatment can:
- worsen pigmentation
- cause rebound darkening
- lead to long-term skin sensitivity
At Stephanie Ho Dermatology:
- treatment is tailored to all skin types
- conservative protocols are used
- emphasis is on safe, sustained improvement
Frequently asked questions
Can melasma be permanently cured?
No. It can be effectively controlled but can sometimes recur.
Are lasers safe for melasma?
Only when used gently and appropriately. Aggressive lasers can worsen the condition.
How long does treatment take?
Improvement is gradual and typically takes several months.
What causes flare-ups?
Sun exposure, hormones, and heat are the main triggers.
