HYDROXYISOHEXYL 3-CYCLOHEXENE CARBOXALDEHYDE
Is HYDROXYISOHEXYL 3-CYCLOHEXENE CARBOXALDEHYDE safe for seborrheic dermatitis?
Hydroxyisohexyl 3-Cyclohexene Carboxaldehyde, also called HICC or Lyral, is best avoided on actively inflamed seborrheic-dermatitis skin where practical. It adds fragrance, offers no seb derm benefit and has a well-documented contact-allergy history.
Large patch-test research involved selected dermatitis patients rather than all cosmetic users, so it cannot predict an individual reaction. Even so, HICC is prohibited in EU cosmetics. If it appears on an older or imported product, a fragrance-free alternative is the simpler choice.

What is HYDROXYISOHEXYL 3-CYCLOHEXENE CARBOXALDEHYDE used for in skincare?
Hydroxyisohexyl 3-Cyclohexene Carboxaldehyde is a synthetic fragrance material formerly used to give cosmetics a floral scent. It does not moisturize, cleanse or treat skin. Because of contact-allergy concerns, it was prohibited in cosmetic products in the European Union after a phase-out period.
