Milia are small, white or yellowish cysts that form just under the surface of the skin. They develop when dead skin cells, specifically keratin, get trapped beneath the surface rather than shedding normally. This results in the formation of these tiny, hard bumps that are often found clustered around the eyes, cheeks, and nose. While milia can appear on anyone, they are particularly common in newborns and adults with certain skin types or conditions.

Unlike pimples or acne, milia are not caused by clogged pores or bacteria. They are, in fact, cysts, and they won’t respond to typical acne treatments. So, no need to break out the harsh cleansers or drying treatments—you’ll need a gentler approach.

The Causes of Milia

While milia are harmless, understanding the causes can help you prevent them or treat them effectively. Let’s look at the key factors that contribute to their formation:

Skin Trauma Milia often develop as a result of skin trauma, such as burns, blisters, or even aggressive skincare treatments. When the skin’s natural barrier is compromised, dead skin cells can become trapped under the surface as the skin heals, leading to the formation of milia. Even something as simple as using harsh products or treatments that irritate your skin can cause milia to form.

Sun Damage: Chronic exposure to UV rays can thicken and damage the skin, making it harder for dead cells to slough off naturally. Sun-damaged skin is less efficient at renewing itself, leading to a buildup of dead skin cells and an increased likelihood of milia. Protecting your skin from the sun by using sunscreen and seeking shade can help reduce this risk.

Use of Heavy or Occlusive Skincare Products: Skincare products that are too heavy or greasy for your skin type can clog the surface, trapping dead skin cells and leading to milia. Occlusive creams, particularly those used around the eye area, can prevent the natural shedding process and contribute to the formation of these tiny cysts. Choosing the right products is essential for preventing milia.

Natural Skin Aging; As we age, our skin’s natural ability to shed dead skin cells slows down. This reduced cell turnover can lead to an accumulation of dead cells on the skin’s surface, increasing the chances of developing milia. Incorporating gentle exfoliation into your routine can help keep your skin smooth and milia-free.

Underlying Skin Conditions; Certain skin conditions, like rosacea or dermatitis, can increase the likelihood of developing milia. These conditions often cause inflammation or damage to the skin, which can trap dead skin cells and lead to milia formation.

How to Prevent and Treat Milia

• While milia aren’t harmful, many people prefer to treat them for cosmetic reasons. Here are some effective ways to prevent and treat milia:
• Regular exfoliation helps remove dead skin cells and encourages cell turnover, preventing them from becoming trapped beneath the skin’s surface. Opt for enzymes as these gently dissolve dead skin cells without disrupting the skin barrier and causing irritation. Be cautious with physical exfoliants, especially around the delicate eye area, as they can be too abrasive and may cause micro-tears or further irritation.
• Since sun damage is a known contributor to milia, it’s crucial to protect your skin from UV exposure. Use a broad-spectrum sunscreen every day, even if you’re staying indoors, as UV rays can penetrate windows. A lightweight, non-greasy formula is ideal to prevent clogging pores or causing additional irritation.
• If you already have milia, it’s best to seek help from a Esthetician for extraction. Milia are encased in a thin layer of skin, which makes them difficult to remove at home without causing damage. Trying to pop them yourself can lead to scarring or infection, so leave it to the professionals!
• If you’re prone to milia, it’s best to avoid using thick or occlusive creams, particularly around the eyes. Instead, avoid applying these around the eye area and opt for an eye cream. Because the eye area is particularly prone to milia, using a well-formulated eye cream can help hydrate and smooth the skin without being occlusive. It’s important to choose an eye cream that addresses common concerns—like fine lines, puffiness, and dark circles—while also supporting the skin’s natural regeneration process.
