If you have recently lost a lot of weight, you’re likely wondering how to tighten skin. You might feel that your skin is looser and less tight than it was before the weight loss. This is because collagen and elastin, the two proteins responsible for maintaining tighter skin, become damaged when skin is stretched for a long time. When you lose weight, the collagen and elastin fibers lose some of their ability to retract. And if you’ve undergone weight loss surgery, research also shows that you will probably have a decrease in newly formed collagen and elastic fibers.
