3. Limit Your Exposure
Your skin needs to be nurtured. Being out in the sun too long and too much exposure to hot and chlorinated water can loosen up your skin even more than it is now. Limit your exposure to both of these things, along with tanning booths and you'll see your skin start to firm up in no time! Besides cutting your risk of skin cancer, this is one of the best ways to deal with loose skin after weight loss.
