Do I have hyperactivity of the orbicularis oris? Will botox/dysport fix my hidden top dry lip? (Photo)

When I press down above my lip, more of my 'dry' lip is visible & i would love this to be permanent. Ive had juviderm b4 but this gave me a trout pout, the thinness stuck out more, it didnt roll up more of my dry lip. Recently an injections nurse put a small amount of Dysport (15units) into the area but the effect was minimal & didnt last long. Want to know if botox/dysport is the best way to correct my hidden top dry lip or if theres another procedure thats better? Id love this fixed ASAP. Thnx
