Makeup
Makeup is another external product that causes stye, specifically old makeup, which causes stye due to the dust build-up that accumulated over time. Some of the compounds present in most makeup products, such as synthetic and natural fragrances, as well as mica, can clog oil glands in the eyelids and cause infections by letting bacteria build up in the blocked space.
Furthermore, forgetting to remove makeup is one of the most common ways to contract skin-related inflammations, namely, acne and stye. And people who have had stye due to makeup are usually not ignorant about taking off makeup. Research has shown that genetically, some people have more sensitive eyes. The study explains eye tolerances and how stye can easily affect a person even if they were careful and thorough about their hygiene.
The brushing of makeup tools is also a cause of why irritation occurs in the eye due to how tiny particles get stuck inside. Furthermore, makeup on the eyes is a breeding ground for bacteria once it penetrates the skin and clogs the oil glands.
