Based on my photo can I get the largest Permalip implant (5mm) in my upper lip? (photo)

Curious for doctors opinions on whether my upper lip can 'handle' the largest permalip implant, 5mm. Was told by a doctor that I could only get the medium size, bc my upper lip was "too small" for the large...but I've seen people with smaller lips than mine go straight to the large.I've had lip injections previously so I already know I like the look of larger lips, I want permanence.Just looking for my top lip to be enhanced.I would like it to be about the same size or bigger than my bottom lip.
