Chloasma in Children: Causes, Signs & Treatment Guide
Sun Protection Calculator for Children
Calculate the correct amount of sunscreen and reapplication schedule based on your child's size, activity level, and sun exposure time. Proper sunscreen application is critical for preventing chloasma.
When a child’s cheeks or forehead develop dark, tan‑like patches, parents often wonder if it’s a harmless tan or something that needs attention. Chloasma is a pigment disorder that creates these brown‑gray patches, traditionally associated with adult women but surprisingly present in kids too. Understanding why it happens, how to spot it early, and what you can actually do about it can spare families a lot of worry.
What Is Chloasma?
Chloasma, also called melasma when it appears in adults, is a form of hyperpigmentation. The condition occurs when melanocytes - the skin cells that produce melanin - become over‑active in localized areas. The excess melanin settles in the upper dermis, creating the characteristic irregular, brown‑gray patches.
Why It Appears in Kids
Most people think chloasma is driven by hormones during pregnancy or oral contraceptive use, but children can develop it for other reasons:
- UV radiation: Sun exposure triggers melanin production. Kids who spend lots of time outdoors without protection are at higher risk.
- Hormonal fluctuations: Even before puberty, the adrenal glands can release cortisol and other steroids that tip the pigment balance.
- Genetic predisposition: Families with a history of pigmentary disorders often pass on a susceptibility.
- Medication side effects: Certain drugs, such as antiepileptics or corticosteroids, can stimulate melanocytes.
- Skin irritation: Chronic rubbing, eczema, or allergic reactions may induce post‑inflammatory hyperpigmentation that mimics chloasma.
In Australia’s strong sun, UV exposure is a leading cause. A recent study by the Australasian College of Dermatologists (2024) found that 18% of children aged 6‑12 with frequent beach visits showed early signs of pigmentary changes, most of which were linked to inadequate sunscreen use.
Key Symptoms to Watch For
Spotting chloasma early helps keep it from deepening. Look for these signs:
- Irregular, brown‑gray patches on the cheeks, forehead, bridge of the nose, or upper lip.
- Symmetry: The patches often appear on both sides of the face.
- Patches may darken after sun exposure and fade slightly in winter.
- No itching or pain - the condition is purely cosmetic.
If you notice any of these, a quick check with a pediatric dermatologist can confirm the diagnosis.
Diagnosing Chloasma in Children
Diagnosis usually starts with a visual exam. Dermatologists may use a Wood’s lamp to highlight melanin depth. In ambiguous cases, a skin biopsy can differentiate chloasma from other pigment disorders.
Key diagnostic steps include:
- Medical history: Ask about sun habits, medications, and family skin conditions.
- Physical exam: Document patch location, size, and color.
- Wood’s lamp assessment: Determines if melanin is epidermal (easier to treat) or dermal (more stubborn).
- Optional biopsy: Reserved for atypical presentations.
Treatment Options Overview
There’s no one‑size‑fits‑all cure, but several proven approaches can lighten the patches and prevent new ones. Below is a quick comparison of the most common options.
| Treatment | Mechanism | Typical Use (Children) | Pros | Cons |
|---|---|---|---|---|
| Topical hydroquinone (2%) | Inhibits tyrosinase, reducing melanin synthesis | Short‑term, under dermatologist supervision | Effective for epidermal pigment | Potential irritation; not for long‑term use |
| Azelaic acid (15%) | Anti‑inflammatory, blocks melanin production | Safe for ages 12+ | Gentle, also treats acne | May cause mild redness |
| Retinoids (tretinoin 0.025%) | Accelerates skin turnover, disperses melanin | Off‑label for children 10+, dermatologist‑guided | Improves texture and tone | Photosensitivity; requires strict sunscreen |
| Laser therapy (Q‑switched Nd:YAG) | Breaks down melanin particles | Reserved for resistant cases, age 13+ | Rapid results | Costly; risk of post‑inflammatory hyperpigmentation |
| Sun protection (broad‑spectrum SPF 30+) | Prevents UV‑induced melanin activation | Daily for all ages | Non‑invasive, essential baseline | Requires consistent reapplication |
For most children, the first line of defense is a combination of sun protection and a gentle topical agent like azelaic acid. More aggressive options, such as hydroquinone or laser, are saved for stubborn cases and always under specialist guidance.
Home Care and Sun Protection
Even the best prescription can be undone by a day at the beach without protection. Here’s a practical routine:
- Apply sunscreen every morning: Choose a broad‑spectrum SPF 30+ cream that contains zinc oxide or titanium dioxide (physical blockers). Re‑apply every two hours during outdoor play.
- Wear protective clothing: Wide‑brim hats, UPF shirts, and sunglasses cut down UV exposure dramatically.
- Limit peak‑sun hours: Try to keep outdoor activities before 10 am or after 4 pm when UV intensity drops.
- Gentle skin cleansing: Use a mild, fragrance‑free cleanser; avoid scrubbing which can inflame the patches.
- Monitor progress: Take photos monthly under consistent lighting to see if the patches are lightening.
These steps not only help manage existing chloasma but also prevent new pigment spots from forming.
When to See a Dermatologist
While occasional sun‑induced darkening is normal, schedule a professional visit if you notice any of the following:
- Rapid spreading of the patches.
- Accompanying skin changes such as itching, scaling, or pain.
- Failure of at‑home sun protection to halt darkening after 4‑6 weeks.
- Any suspicion that medication (e.g., steroids) might be contributing.
A pediatric dermatologist can tailor treatment, monitor for side‑effects, and advise on safe product concentrations for a child’s delicate skin.
Frequently Asked Questions
Is chloasma the same as a regular tan?
No. A tan fades uniformly when sun exposure stops, while chloasma forms uneven, brown‑gray patches that persist even after the sun is out.
Can over‑the‑counter products clear chloasma in kids?
Mild agents like azelaic acid or low‑strength niacinamide can help, but they work best alongside strict sun protection. Stronger prescription creams should only be used under doctor supervision.
Will chloasma go away on its own?
Sometimes the patches lighten gradually, especially if UV exposure is reduced. However, many children need active treatment to achieve noticeable improvement.
Is laser therapy safe for children?
Laser treatment can be effective but carries a risk of further pigmentation if not performed by an experienced pediatric dermatologist. It’s generally reserved for stubborn cases after other options have failed.
How often should sunscreen be reapplied on a child?
Every two hours, or immediately after swimming, sweating, or towel‑drying. Consistency is key to keeping UV‑induced pigment from worsening.
Armed with the right knowledge, parents can confidently address chloasma, protect their child's skin, and keep those tricky patches from becoming a lifelong concern.

A structured sun‑protection regimen, begun at the earliest signs of pigment change, offers the most reliable safeguard against progression. Parents should apply a broad‑spectrum SPF 30+ lotion each morning, reapply bi‑hourly during outdoor activities, and combine it with protective clothing such as wide‑brimmed hats. In addition, a gentle topical agent-preferably azelaic acid at 15 %-may be introduced under dermatological supervision to promote even fading. Consistency, rather than occasional effort, is the cornerstone of success. By treating the skin with the same discipline applied to academic study, families can prevent lasting discoloration and preserve the child’s confidence.
