Why should individuals with sensitive skin avoid chemical exfoliants?

Individuals with sensitive skin should avoid chemical exfoliants primarily because these products can lead to irritation and discomfort. Chemical exfoliants contain active ingredients such as alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs) that work by dissolving the bonds between dead skin cells. While effective for many, these acids can be too harsh for sensitive skin types, which tend to react more dramatically to stimulants.

The sensitive skin may respond with redness, stinging, or a burning sensation after applying these exfoliants. This reaction can exacerbate existing conditions, such as eczema or rosacea, leading to further discomfort and making the skin barrier more vulnerable to environmental stressors. Therefore, opting for milder physical exfoliants or avoiding exfoliation altogether is often recommended for those with sensitive skin.

The other options do not directly relate to the reasons sensitive skin individuals need to be cautious. They do not address the potential skin reactions that can occur with chemical exfoliants.
