Hi ! Hyaluronic acid is a normal constituent of the skin . Hence there is no harm in using it . It comes in a gel form or an injectable form . It replenishes the skin and gives a hydrated look . Since you have mentioned that you have acne and scars , you can look for other treatment options like peels , microneedling , lasers , a combination of which can give you a better skin . Hope this helps !
Next Steps
Don’t forget to use a sunscreen on a regular basis .
