With the purchase of a Smile Luxe 119 + training pack, you will have at your disposal 20 product kits including 20 teeth whitening gels with 0.1% peroxide. If you follow our protocol, you will be able to perform 22 complete 1-hour treatments in 3 sessions of 20 minutes each. Depending on the practices of beauty professionals, you may opt for shorter sessions of 20 or 40 minutes. The number of treatments performed will then be greater. However, we recommend that you have a full one-hour treatment to optimize the results of your teeth whitening.
