Sensitive skin is a subjective self-assessment tied to discomfort from personal care products, varying from redness and itchiness to dryness and breakouts. Allergies to ingredients like fragrances can exacerbate reactions. Skin sensitivity arises from touch or dryness due to conditions like eczema, rosacea, or aging-related oil gland inactivity. Factors like sunburn or medications can trigger sensitivity. Impaired skin barrier function in these conditions leads to heightened absorption of applied products, causing stinging and burning sensations. Excessive use of exfoliating agents further contributes to prolonged skin discomfort.
