About

Medrysone is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Medrysone is a fluorinated corticosteroid that suppresses inflammation through glucocorticoid receptor activation. The EU Cosmetics Regulation prohibits corticosteroids as cosmetic ingredients (not listed in positive annexes); they are regulated as medicinal substances. Use in cosmetic eye products is not permitted.

Known concerns

  • EU Annex II — corticosteroids generally prohibited in cosmetic products
  • Risk of skin atrophy with prolonged topical use
  • Potential for eye damage if used in ophthalmic cosmetics
  • Systemic absorption risk
