Do I use my hyaluronic acid before applying my normal moisturiser or after?

Your regimen should be in this order:

1. Cleanse 

2. eye serum/gel

3. face serum 

4. moisturizer

5. sun block

As far as hyaluronic acid: many serums contain hyaluronic acid-- the ingredient of most dermal fillers. This works as a great glide for microneedling. However, please keep in mind that the skin does not absorb hyaluronic acid and put it into the dermis-- if it did we wouldn't need to inject fillers! My recommendation is to use a good face serum with Vitamin C and/or anti-oxidants in it. Serums vary and some are best for dry skin while some are better for oily skin. It is best to design your skin care regimen based on your Skin Type. I use the Baumann Skin Type, as it is the only scientifically validated system. 

Hi there,Hyaluronic acid based skin care products should be the first thing applied to freshly cleansed skin. You want the moisturizing properties to be absorbed by the skin without any barriers.
