Non-Significant Undesirable Effects

  • No undesirable effects, other than redness, dryness or irritation of the skin are reported.
  • A tingling sensation and mild redness might occur immediately after application, and it will usually disappear after 30 minutes. This is a normal reaction and may happen during the first few days of application.
  • After 6 weeks of application of cysteamine, the risk of skin irritation reduces considerably (skin hardening).
  • There is no limit for the long-term use of cysteamine.

How to prevent undesirable effects

Undesirable effects happen when:

  • The face is washed just before the application (minimum 1h interval to be respected)
  • Long exposure times
  • Concomitant use with other topical products

Undesirable effects become very rare if:

  • No longer than 15 minutes of exposure
  • 1 hour interval between washing and application
  • Adequate moisturization after removing the cream
