Hi girlies~ I came across these methods of using hyaluronic acid while learning about skincare. I'd like to know if any of you have tried them? Do they really work?

It says: "1. Mix and match foundation: Add 1 drop of hyaluronic acid essence to your foundation for a smooth, non-caking finish – a savior for dry skin. 2. Emergency mask: Soak a cotton pad with hyaluronic acid essence and apply as a mask for 5 minutes; instantly transforms tired-looking skin into hydrated skin. 3. Use with a face mask: Apply a layer of hyaluronic acid essence before applying a face mask to promote the absorption of subsequent nutrients." It also adds, "Pure hyaluronic acid essence can draw moisture from the skin in dry environments, so be sure to layer it with lotion/cream to lock in moisture!"

Can you share your honest user experience?
