Truthfully, there’s nothing wrong with “mixing and matching” products from various ranges. What you do need to be careful of, is whether or not any of the active ingredients “clash”. Of course, you need to be sure that you’re using products that are properly suited to the needs of your skin. I would say, that you should rather be safe and ensure that a qualified medical aesthetics therapist or doctor does a skin analysis on your skin and ensures that your product combination is what is best for YOU.
