Depends on your age and your ethenticity.
Certain people NEVER lose the elasticity in their skin. Others are pre-destined to get RUINED by yo yo weight loss & gain.
I am the later.
And don't believe the co co butter thing either. It won't hurt to use it... it makes you feel and smell great, but if you are an "OLDER" person and yo yo'd a lot over the years, You can jump & can pump all the iron you want and build as much muscle mass as you can...
Believe me... once the skin has lost it's elasticity... WELL... that's what God made Plastic Surgeons FOR!
And all you youngins out there that don't believe this... well...
YOUR DAY WILL COME!
