What causes heat rash/milia? A look at all the causes of heat rash/milia.

The main causes of heat rash can be both external and internal factors that trigger skin blockage and irritation, especially in hot weather or for those with oily skin. The main causes of heat rash are as follows:

• Sweat and heat accumulate.

When the body is exposed to hot weather, the sweat glands work harder. When sweat accumulated on the face mixes with dirt and oil, it can easily clog pores, leading to the formation of small bumps or pimples, especially in areas that are damp or frequently rubbed.

• Oiliness on the skin 

People with oily or combination skin often produce more oil than normal. When this oil accumulates along with dead skin cells, it increases the chance of clogged pores, making it easier for acne breakouts to occur and recur frequently. 

• Exposure to strong sunlight 

Exposure to intense sunlight can cause skin inflammation and irritation. Sunlight and UV radiation trigger inflammation and increase skin sensitivity, weakening the skin and clogging pores, leading to more noticeable acne breakouts.

• Using cosmetics or skin creams that are too heavy.

Using heavy, oil-based, or comedogenic cosmetics or skincare products can easily trigger acne breakouts, especially in hot weather and when sweat accumulates on the face.

Heat rash, also known as milia, is a skin problem caused by a combination of factors including heat, sweat, oil, and using products unsuitable for your skin type. While not severe acne, if not properly cared for, heat rash can recur.

Those with dry skin often develop small bumps, and their skin may feel rough, stinging, itchy, peeling, and red.
• People with combination skin Combination skin often has oily T-zone areas, causing small bumps (acne) to appear only in specific spots, in patches not covering the entire face, especially on the forehead or hairline.
