Tiny Bumps Under the Skin? What You Need to Know About Milia

Welcome to Skin Insights by YSBB.

Have you ever noticed small, white bumps around your eyes or cheeks that feel like tiny grains under the skin?

These are called milia—not acne or sebum plugs, but keratin-filled cysts that form just beneath the skin’s surface. While painless, they often linger and don’t go away on their own. Today, let’s explore what causes milia, how to treat them safely, and tips for prevention.

What exactly are milia?

Milia are tiny, white or yellowish bumps made of trapped keratin under the skin. They’re most common in areas with thin skin like the under-eye area, cheeks, or forehead.

• They’re not pimples or oil-based comedones, but hardened dead skin cells.
• Usually painless and non-inflammatory, but visually persistent.

Why do milia form?

Milia develop when skin turnover slows and dead skin cells become trapped instead of naturally shedding. This can occur under several conditions:

• Sluggish skin turnover: Keratin builds up beneath the surface, especially with aging or skin thickening.
• Post-procedure healing: Laser, peeling, or surgical recovery can lead to secondary milia formation.
• Heavy skincare products: Occlusive creams like rich eye creams can block normal exfoliation, especially on delicate areas.
• Genetic predisposition: Some skin types naturally shed keratin less efficiently, leading to recurring milia.

Can I remove them at home?

It’s important to resist the urge to squeeze or pick at milia. Unlike acne, they don’t have an opening and can’t be expressed without damage.

• Forcing them out can cause bruising, pigmentation, or scarring.
• Especially around the eyes, this can lead to sunken skin or prolonged redness.

How can I prevent milia?

While they can form spontaneously, a few skincare habits can help reduce recurrence:

• Gentle exfoliation: Use enzyme-based exfoliants 1–2 times per week to keep turnover steady.
• Use lightweight eye creams: Choose quick-absorbing formulas and apply sparingly with soft tapping motions.
• For frequent cases: Consider regular professional extraction or consultation with a dermatologist.
