Is fragrance bad for skin?

Fragrance — both synthetic and natural — is one of the most common causes of allergic contact dermatitis and skin sensitization. While many people tolerate fragranced products without issues, fragrance serves no functional skincare purpose and adds risk without benefit. Sensitive skin, rosacea-prone, or barrier-damaged individuals should prioritize fragrance-free formulations. Natural fragrances like essential oils carry the same risk as synthetic ones and are not inherently safer.
