What are some skin tightening options for ehlers danlos?

Im 25 with severe loose skin on my thighs stomach and arms due to ehlers danlos syndrome and significant weight loss. Would thermage or laser skin tightening work? I had a consultation for thermage today and the doctor said she doesn't know if it would do anything because my collagen is not normal. Planning a tummy tuck for my stomach once I have children but want to improve my appearance much before this as that's many years away. I'm devastated by how I look and desperate for any improvement
