I am so grateful that to have lost the weight and gained my life back, that any shar-pei-ness just doesn't get to me. A bikini body I will never have due to this fact, but you know what? - Loose/wrinkly/excess skin won't cause high blood pressure, stroke, high cholesterol, heart attacks, gout, liver disease, numerous cancers, acid reflux, diabetes and a slew of other debilitating and deadly diseases.
Sounds to me like you're doing everything right, the rest is up to mother nature. And yes, it will improve over time.
Congratulations on your weight loss thus far. I look forward to hearing of your continued progress.
