What is the difference between a hypertrophic scar, keloid, and a normal scar?

Keloids tend to be larger scars than the wound edges themselves and are  often described as having edges that spill over.  On the other hand, hypertrophic scars do not have edges that spill over, but do raise upwards. These scars can occur due to minor injury (even from just from a pimple), or due to a more invasive wound. An overactive scar response with an overproduction of granulation tissue and collagen create these unsightly scars. Certain ethnicities are more prone to develop keloids, especially those of African or Asian descent. When we see patients in the office with keloids or hypertrophic scarring, we often treat with corticosteroid injections. These help flatten the scars over time and may involve several injections, each spaced a month apart.  If you have any questions or concerns regarding your scarring, come see us in the office!
