A clinical study according to GCP guidelines at a German university institute confirms the skin smoothing effect of TIME CONTROL RetiNight Essence.
RETINOL ACCLIMATION: For beginners, it's best to use RetiNight Essence once a week to give your skin time to adjust. After two weeks, you can gradually increase applications, but still sparingly.
Remember to Start Slow. One of the most common mistakes people make when starting to use retinol is using it every single night. For many people, that's far too often, especially as your skin adjusts!CONTRAINDICATIONS: Not to be used while breastfeeding, during pregnancy, or while trying to conceive, as well as during the use of Roaccutane (Isotrentinoin based medications), and additional acne medications.
