Which ingredient is typically avoided in waterproof makeup due to irritation risks?

Fragrance or alcohol is typically avoided in waterproof makeup primarily due to their potential to cause skin irritation. Many individuals have sensitivities or allergic reactions to these ingredients, which can lead to skin discomfort, redness, or inflammation, especially in sensitive areas like the eyes.

Waterproof makeup products are designed to withstand moisture and sweat, which means they often include heavier formulations that can already be taxing on the skin. Adding fragrant elements or alcohol compounds can exacerbate irritation or dryness, making it essential for manufacturers to prioritize skin-friendly formulations in products meant for long wear.

On the other hand, while water is a common solvent in many cosmetic formulations, it is not typically a source of irritation. Mineral oil and petroleum jelly, though occlusive, are often well-tolerated by the skin and serve different purposes in formulations, such as providing moisture and creating barriers. Therefore, the focus on avoiding fragrance or alcohol is crucial to ensure a more comfortable experience for users of waterproof makeup.
