How are they similar?
ormally when you sustain a wound or injury, your body repairs itself by producing new collagen in the area so that eventually the scar looks like normal skin. Both hypertrophic and keloid acne scars are caused by excess collagen build up that causes a scar to form in a lump or a bump.1 These scars tend to form on the back, chest, ears, and jaw line. Both types of scarring occur more frequently in African-Americans and Hispanics (up to 15 times more than in Caucasians) and in patients of Asian descent (up to 5 times more than Caucasians).2
How are they different?
Hypertrophic scars stay confined to the original scar borders. They appear pink, raised, and firm. Keloid scars tend to be more reddish-purple and to expand beyond the borders of the original wound.3 Keloid scars may also cause pain, itching, burning and limited range of motion (if they occur over a joint).
