Is pure hyaluronic acid mixed with water okay to put on my scars?

3 weeks post op from tummy tuck, breast surgery and Lipo. I have been drinking pure hyaluronic acid mixed with water for a while now and i was wondering if I make a paste up of water and HA would it be good to help the healing process, elasticity of my skin/scars? I do use it on my face. And also I got a laser burn during Lipo could I put it on that? Thankyou
