Q: Can I mix skin care products from different brands or do I need to use the same brand for all my skin care products?
A: Yes. If you like a product and it works for you, use it. They only person that will tell you different if the person trying to sell you a their entire line of products!
That being said, be careful of using multiple products that have similar ingredients. the most common example of this is using more than one product to exfoliate and ending up with irritated skin.
