This is a very important question! Thank you for asking it! It’s actually quite a common mistake that many people make. When you are using a cosmeceutical containing retinoids, you definitely have to stop using these when you are going to go and have laser treatments (any laser for that matter). You should stop applying your retinoids 3 days prior to the treatment and you can then resume application 5 days after the treatment. (this is a general guideline, some treatment may require slightly longer waiting periods before resuming the use of your products).
