Why Milia Forms & How to Prevent It in Singapore’s Humidity

Introduction

Singapore’s climate is known for three things — heat, humidity, and sweat. While the tropical weather gives us beautiful greenery all year round, it can also wreak havoc on the skin. From clogged pores and excess oil to stubborn breakouts, the humid air creates the perfect environment for small white bumps known as milia to appear.

Unlike acne, milia don’t contain pus, bacteria, or inflammation. Instead, they’re tiny keratin cysts trapped beneath the surface of the skin — appearing like hard, white, or yellowish pearls, most commonly around the eyes, cheeks, or forehead.

Many Singaporeans notice these bumps appearing despite following a consistent skincare routine, which raises the question: why do milia form, and how can we prevent them — especially in a hot, humid climate like Singapore’s?

In this comprehensive 2025 guide, we’ll explore:

• What milia are and how they form
• Why Singapore’s humidity makes them more common
• The types of milia and who’s most at risk
• Proven prevention strategies
• Medical and skincare solutions that work
• And why Dr Plus Clinic Singapore is the trusted choice for safe and effective milia management

What Exactly Are Milia?

The Basics

Milia are small, dome-shaped cysts that form when keratin — a structural protein found in the skin — becomes trapped beneath the surface. They are not a sign of poor hygiene or acne, and squeezing them won’t help because they don’t have an opening.

Each milium (singular form) is about 1–2 millimetres wide and feels hard to the touch, almost like a grain of sand. They are non-inflammatory, meaning they don’t cause redness or pain, though some people find them cosmetically bothersome.

Common Locations

• Around the eyes (especially under-eye area)
• On the cheeks and temples
• Around the nose
• On the forehead
• Occasionally on the chest or neck

Because milia often appear in clusters, they can give the skin a rough or uneven texture, even if the rest of the complexion is smooth.

Why Do Milia Form?

Milia develop when dead skin cells, keratin, or sebum become trapped under the outer layer of skin (epidermis). This can happen for several reasons — and in Singapore’s humid weather, these factors become even more pronounced.

1. Overproduction of Keratin

Keratin, while essential for protecting the skin, can build up excessively when the skin’s natural exfoliation slows down. In hot, sticky weather, this process becomes worse as sweat and sebum accumulate on the skin’s surface.

2. Blocked Pores

In high humidity, pores are more likely to trap oil, sunscreen residue, and dead skin cells. Over time, this blockage prevents normal cell turnover, allowing keratin to get trapped and form milia.

3. Heavy Skincare or Makeup

Rich creams, thick sunscreens, and silicone-based products can create a film on the skin that blocks natural exfoliation — especially around the eyes and cheeks where milia are common.

4. Sun Damage

Chronic UV exposure (a constant issue in tropical Singapore) thickens the outer skin layer, making it harder for dead cells to shed naturally. This creates the perfect environment for milia to form beneath the surface.

5. Post-Skin Trauma

After burns, laser treatments, or rashes, skin regeneration may produce excess keratin. The healing skin can trap this keratin under new layers, leading to secondary milia.

6. Aging and Slower Cell Turnover

As we age, the skin’s natural exfoliation process slows down. Combined with reduced oil production, this makes it easier for dead cells to build up and become trapped.

Why Milia Are More Common in Singapore’s Humid Climate

Humidity may sound like it keeps the skin hydrated, but in reality, it creates the ideal breeding ground for pore congestion and excess sebum production.

Here’s why tropical weather increases the risk of milia formation:

1. Increased Sweat and Oil Production

High humidity stimulates sweat glands and sebaceous glands. The constant mix of sweat and oil can clog pores, preventing proper exfoliation.

2. Heavier Skincare Layers

Many people over-moisturise or apply multiple layers of sunblock to protect against UV rays. These occlusive layers can trap keratin and dead skin, especially when combined with perspiration.

3. Frequent Makeup Use

In a climate where people sweat easily, many rely on long-lasting, waterproof makeup — which tends to be thicker and more pore-clogging.

4. Environmental Pollutants

Urban humidity traps pollutants and microscopic particles in the air. These settle on the skin, worsening congestion and barrier dysfunction.

5. Constant Air Conditioning Exposure

Switching between hot outdoor air and cold, dry indoor air from air-conditioning can confuse the skin barrier, leading to dehydration and poor turnover — another risk factor for milia.

Types of Milia

1. Primary Milia

The most common type, forming spontaneously when keratin is trapped under healthy skin. Often seen in younger adults.

2. Secondary Milia

Occurs after skin injury, inflammation, or prolonged use of heavy creams. Common in those with sensitive or sun-damaged skin.

3. Milia en Plaque

Rare type associated with inflamed skin patches, typically behind the ears or on cheeks.

4. Multiple Eruptive Milia

Clusters that appear over time, often on the upper torso or face.

5. Neonatal Milia

Common in infants; usually disappear naturally within weeks.

In adults, however, milia don’t fade on their own — they need proper extraction or exfoliation.

Who Is Most Prone to Milia in Singapore?

• Those with oily or combination skin — excess sebum leads to clogging.
• Individuals using heavy creams or sunscreen — especially around the eyes.
• People exposed to sun daily without SPF — UV thickens the skin barrier.
• Those who skip exfoliation — dead skin builds up easily.
• Older adults — slower cell turnover increases buildup.
• Patients with previous burns, laser, or rash — healing skin traps keratin.

How to Prevent Milia in Singapore’s Humid Climate

While professional extraction is the most effective way to remove existing milia, prevention focuses on keeping pores clear, maintaining healthy exfoliation, and avoiding barrier overload.

Below are proven prevention strategies recommended by doctors at Dr Plus Clinic Singapore.

1. Cleanse Properly — But Gently

Choose a mild, pH-balanced cleanser that removes excess oil, sweat, and sunscreen without stripping natural moisture. Over-cleansing can damage the barrier, while under-cleansing leaves debris that traps keratin.

Tips:

• Wash twice daily — once in the morning and once at night.
• Use lukewarm water; avoid hot water that dries out the skin.
• Double cleanse if you wear makeup or sunscreen.

2. Exfoliate Regularly (But Don’t Overdo It)

Exfoliation is key to preventing milia because it removes dead skin cells and encourages cell turnover.

Options:

• Chemical exfoliants: Look for products with AHA (glycolic acid) or BHA (salicylic acid) to gently clear debris.
• Enzyme exfoliants: Great for sensitive skin — derived from fruit enzymes like papaya or pineapple.

Frequency:
1–2 times per week for sensitive skin, 3 times for oily skin.

Avoid: Harsh scrubs or microbeads that can damage the skin barrier.

3. Use Lightweight, Non-Comedogenic Moisturisers

In Singapore’s humidity, heavy creams can suffocate the skin. Switch to gel-based or water-based moisturisers that hydrate without clogging.

Look for ingredients like:

• Hyaluronic acid — lightweight hydration
• Niacinamide — balances oil and strengthens barrier
• Panthenol — calms irritation

4. Choose the Right Sunscreen

SPF is non-negotiable in tropical climates, but choose wisely. Thick, greasy sunscreens can cause milia, especially around the eyes.

Go for:

• Oil-free or gel-type sunscreens
• Mineral-based SPF (zinc oxide or titanium dioxide)
• Fragrance-free formulas for sensitive skin

5. Incorporate Retinol or Vitamin A

Retinol accelerates cell turnover and helps prevent keratin buildup — one of the main causes of milia.

Start with a low concentration (0.25%–0.5%) and apply only at night, 2–3 times per week.

Note: Retinol should be avoided during pregnancy and used under professional guidance if you have sensitive skin.

6. Avoid Heavy Eye Creams

Milia commonly appear under the eyes because people often use thick, occlusive creams there. Instead, choose lightweight, peptide-based serums or gel creams that absorb quickly.

Apply gently with your ring finger — avoid rubbing or over-application.

7. Protect Against Sun Damage

Excess UV exposure thickens the skin, trapping dead cells underneath. Wear SPF 50+ daily and reapply every 3–4 hours, especially when outdoors.

A wide-brimmed hat or umbrella also helps protect sensitive areas.

8. Keep Skin Cool and Balanced

After long days outdoors, rinse sweat and oil off as soon as possible. Consider using cooling facial mists or gentle toners with witch hazel or aloe vera to refresh and balance the skin.

9. Avoid Picking or Squeezing Milia

Trying to pop milia at home can cause scarring, infection, and inflammation. These bumps are enclosed cysts without openings — so squeezing only worsens the problem.

If milia persist, seek professional extraction instead.

When to Seek Professional Help

If milia persist for more than 2–3 months despite good skincare, or if they cluster in sensitive areas (like around the eyes), it’s best to see a doctor.

Professional treatments at Dr Plus Clinic Singapore safely and effectively remove milia using advanced techniques such as:

• Manual extraction with sterile needle
• Electrocautery (heat-based removal)
• Laser resurfacing (CO₂ or Er:YAG laser)
• Gentle chemical peels for prevention

These treatments are performed by medical professionals to ensure precision, hygiene, and scar-free results.

Frequently Asked Questions (FAQ)

1. Can milia go away on their own?

Infant milia may fade naturally, but adult milia usually require extraction or exfoliation for removal.

2. Does humidity really make milia worse?

Yes — sweat, oil, and heavy products clog pores, trapping keratin and worsening buildup.

3. Are milia the same as whiteheads?

No. Whiteheads are clogged pores with sebum and bacteria, while milia are keratin cysts with no inflammation.

4. Is laser safe for milia removal?

Yes. Low-energy lasers like CO₂ or Er:YAG are safe for Asian skin when performed by qualified doctors.

5. How often should I exfoliate?

2–3 times a week is sufficient. Over-exfoliating can damage the barrier.

6. What skincare ingredients help prevent milia?

Look for retinol, niacinamide, AHAs, and enzymes — they promote healthy cell turnover.

7. Can I prevent milia completely?

While you can’t eliminate risk entirely, the right skincare and humidity control drastically reduce recurrence.
