Dr. Deborah Longwill, Dermatologist at Baptist Health South Florida, says after your 30, you will get a little bit more narrow and then you’ve lost your support of the skin. “So you’re not only losing your collagen, but you’re also losing your fat; the bones and the muscles start to shrink and become more narrow and then there’s no support of the skin,” she explains.

She highlights doctors use fillers to fill not just the lines, but to replace volume where the bone and the fat have started to diminish and to support the skin back up to where it was before.
