I use both Aloe Vera and even Witch Hazel to tighten my skin.
I rub the Aloe Vera directly into the skin to treat saggy skin and tighten the saggy skin.
For coconut oil to tighten skin massage the coconut oil into the skin and leave it on overnight.
Another home remedy for skin tightening is egg whites and honey to use egg whites and honey for skin tightening you separate 1 egg white from the yolk and then mix the egg white with 2 tablespoons of honey and apply it to the skin.
You'll need to apply the egg white and honey mask up to 3 times per week to see results.
