If you have an excess amount of skin, the best way to go about this would be working out and exercising. You'd want to do a workout aimed at increasing your muscle mass, by increasing your muscle mass your excess skin will need to cover more body mass. Exercising has also shown in several studies to 'tighten' up your skin.
I see many recommend the P90X program, while its a decent program at most i wouldn't recommend it since theres a lot of better alternatives. You'd probrably want to lift heavy weights too.
So what i would recommend is doing a fullbody workout 3-4 times a week, this requires you have weights or get into a gym. The fullbody workout could look like this for example:
Squat
Deadlift
Calf presses
Benchpress
Military Press
Wide Grip Pulldowns
Cable Rows
1-2 ab exercises. (Ab Crunches, Hanging leg raises for example)
Don't buy into high rep workout, it doesn't do much except for your endurance. Try to do 4 sets of 6-8 reps. Stomach exercises maybe go up to 12, if you find that too easy then add weight. Doing 30-40 Ab crunches is totally useless unless you it makes you feel awesome to do that many, but you'd probrably feel more awesome with a well build stomach so keep it under 12.
Anyway, if your serious then get a proper diet, building muscle requires lots of protein (1.5 gram per kg lean body mass), eat plenty of healthy fats (nuts for example). Give yourself small goals, if you aim for perfection at start itll be long untill you see results and your motivation will be lost. I don't know if your happy about your current weight or want to loss more. You cant build muscle while losing weight. You need to eat plenty to build your muscle (being in a calorie surplas). Learn the basics and do some research and hopefully you'll get results.
