About

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

Desogestrel is a third-generation synthetic progestogen listed on EU Annex II (prohibition list) under Regulation 1223/2009, prohibiting its use in cosmetic products entirely. Like other sex hormones, it is classified as an endocrine disruptor and cannot be included in any cosmetic formulation regardless of concentration. This ban applies universally across EU member states.

Known concerns

  • EU Annex II banned substance - sex hormone
  • Endocrine disruption classification
  • No permitted use in cosmetics
