Fragrance and alcohol are often advised against when formulating products for sensitive skin due to their potential to cause irritation, inflammation, or allergic reactions. Fragrance can introduce a variety of allergens and irritants that may lead to redness or discomfort, while alcohol can strip the skin of its natural oils, leading to dryness and further sensitivity. Products designed for sensitive skin are typically formulated to minimize these irritants, focusing instead on soothing and hydrating ingredients that promote skin health without triggering adverse reactions.

In contrast, vitamins and minerals, natural oils, and exfoliating agents can serve beneficial roles in skincare, though they may need to be used cautiously based on individual skin responses. However, fragrance and alcohol are widely recognized for their potential to exacerbate sensitivity and should generally be avoided in these cases.
