Plump fine lines in lips

I had been wanting to try lip filler but was super nervous because I get trama induced cold sores. I took 1000 mg of Valtrex a day before, of and 2 days after and I was sooooo happy I didn't get 1 cold sore! Now, on to the injections. I have full lips already, I wasn't trying to go bigger but just to smooth the fine lines in my lips. It hurt a bit but afte the first few injections the lidocaine set in and I could t feel it. It's been about 6 weeks since my filler and I do think they have gone down a bit but still happy. Will see if it really last 6 months
