To prepare for IPL therapy, please avoid sun exposure and self-tanners for 2 – 4 weeks prior to the procedure. You might need to discontinue the use of Retin-A/Renova for 1 to 2 weeks prior to your procedure, and we may recommend that you avoid taking OTC blood thinners and anti-inflammatory medications one week before the treatment to help prevent bruising (all recommendations will be discussed during your consultation). You also need to use sunscreen between treatments.
