i do for hydration! Its in a lot of my other skincare products (ie moisturizer) but I use the MB dew drops to lock in moisture if I’m feeling particularly dry and follow up with some vaseline. (I can only tag the MB dew cream but the dew drops also exist and they are great because you need a small bit and its super hydrating).
I have dry sensitive skin and have seen a dramatic difference with adding that and Vit C in my routine! Though, I have been using many actives previously. HA is a nice to have but not a need to have.
