The Claim

Scar tissue, characterized by dense collagen deposition, lacks hair follicles and sweat glands, resulting in structural and functional differences compared to healthy skin.

Description
1 study reviewed
In plain English

Scar tissue doesn't have sweat glands or hair like normal skin, so it works and looks different.

See the scientific wording

The dense collagen in scar tissue lacks hair follicles and sweat glands, making it structurally and functionally distinct from healthy skin.

What the research says

1 study

  1. Study: 3D bioprinting of prefabricated artificial skin with multicomponent hydrogel for skin and hair follicle regeneration

    The study created lab-grown skin that can grow hair and glands, which normal scar tissue can't do, so it supports the idea that scars are different from healthy skin.
