Milia (Milk Spots): Symptoms, Removal and UK Treatment Guide

Milia, commonly referred to in the UK as milk spots, are small, raised, pearly-white or yellowish bumps that appear on the skin. They are most frequently found on the face, particularly around the eyelids and cheeks, though they can occur anywhere on the body.

Unlike acne, milia are not filled with sebum or bacteria. Instead, they are tiny cysts filled with keratin, a protein found in skin, hair, and nail tissue. While they are extremely common in newborn babies (where they usually clear up without intervention), they can persist in adults for months or even years. In adults, milia are categorised as either primary—appearing spontaneously—or secondary, which often follow skin trauma or the use of heavy skincare products.

Understanding why milia form is the first step toward effective management. In adults, the skin's natural exfoliation process sometimes fails, leading to dead skin cells becoming trapped in small pockets near the surface. Key contributing factors include:

• Heavy Skincare: Using oil-based or highly occlusive moisturisers (such as those containing liquid paraffin or petroleum) can block pores and prevent keratin from escaping.
• Sun Damage: Long-term sun exposure can lead to thicker skin, making it harder for cells to shed naturally.
• Skin Trauma: Rashes, blisters, or even professional treatments like dermabrasion can sometimes trigger 'secondary' milia during the healing process.
• Genetics: Some individuals are simply more prone to keratin retention than others.

How to identify milia

Milia typically have a very specific appearance. They are usually 1mm to 2mm in size, feel firm to the touch (almost like a tiny seed under the skin), and lack the redness or inflammation associated with a typical whitehead or spot. They do not have an obvious pore or 'head' that can be squeezed.

What else could it be?

It is important to differentiate milia from other conditions such as syringomas (benign sweat gland growths) or xanthelasma (cholesterol deposits around the eyes). If a bump is growing rapidly, bleeding, or looks irregular, a professional review is essential to rule out more serious skin lesions. Using a UK online doctor service can provide a convenient way to get a visual assessment of your symptoms from the comfort of home.

While milia are harmless, many patients seek treatment for cosmetic reasons. According to NHS guidance, milia do not usually require treatment unless they are causing distress. However, if they do not clear on their own, several options are available:

• Topical Retinoids: Creams containing vitamin A (retinol or prescription-strength tretinoin) can help speed up cell turnover, encouraging the milia to reach the surface.
• Chemical Peels: Professional exfoliating treatments using Salicylic or Glycolic acid can thin the surface layer of the skin.
• Manual Extraction: This should only be performed by a trained professional. It involves using a sterile lancet to create a tiny opening in the cyst, allowing the keratin plug to be gently removed.
• Cryotherapy or Cautery: In some cases, a dermatologist may use extreme cold or heat to destroy the cyst.

Crucially, you should never attempt to squeeze milia at home. Because the content is hard and deep, squeezing will likely cause bruising, infection, and permanent scarring without actually removing the keratin.

If you are unsure whether the bumps on your face are milia or another condition, it is wise to speak to a GP online. An online consultation allows you to share high-quality images of the affected area, helping a clinician provide an accurate diagnosis.

You should consider a consultation if:

• The bumps are located very close to the eye or on the eyelid.
• The area is becoming red, painful, or inflamed.
• You have tried over-the-counter exfoliants for several months with no improvement.
• The bumps are spreading or changing in appearance.

A UK online doctor can provide advice on suitable dermatological products and, if necessary, issue a private prescription for retinoids that are not available over the counter.

Once you have successfully cleared your skin, prevention is key. To reduce the likelihood of new milia forming:

• Switch to 'Non-Comedogenic' Products: Look for skincare and make-up labelled as non-comedogenic, meaning they are formulated to not block pores.
• Regular Exfoliation: Incorporate a gentle chemical exfoliant (like a BHA or AHA toner) into your weekly routine to assist the shedding of dead skin cells.
• Sun Protection: Apply a broad-spectrum SPF daily. Sun-damaged skin loses its ability to shed cells efficiently, leading to more trapped keratin.
• Avoid Eye Creams that are Too Rich: The skin around the eyes is thin; heavy creams are a leading cause of milia in this area. Opt for lightweight gels instead.
