How Are Milia Formed?

Milia typically form due to excessive proliferation of keratinocytes on the skin's surface, blocking hair follicle openings and impeding the normal excretion of sebum. This condition may be associated with improper skin cleansing, excessive sebum production, minor skin trauma, and other factors. It is recommended to seek medical attention promptly and implement targeted improvements based on the underlying causes.

1. Improper Skin Cleansing

If skin cleansing is not thorough, residual makeup and dirt can clog pores, preventing sebum excretion and leading to milia. It is advisable to use gentle cleansing products and engage in regular deep cleansing routines.

2. Excessive Sebum Production

Individuals with oily skin are more prone to milia because excessive sebum secretion easily clogs hair follicles. Oil-controlling products, such as facial cleansers containing salicylic acid, can help regulate sebum production.

3. Minor Skin Trauma

Friction, pressure, or other forms of minor skin trauma can lead to keratinocyte proliferation, resulting in milia. Avoid excessive skin friction and reduce unnecessary pressure. In daily life, maintain skin cleanliness, avoid overly greasy skincare products, and engage in regular skin care routines.

If milia are numerous or impact aesthetics, consult a doctor promptly. They may recommend using Vitamin A acid medications, salicylic acid preparations, or fruit acid products, but these should be used under medical supervision.
