Keloid and hypertrophic?

What is the difference between keloid and hypertrophic scars? Is there any possible way to make them less noticeable?

Keloid and hypertrophic?
ok, from what my dr. told me, keloids are raised and expand past the wound site, while hypertrophic scars a basically only on the site of the wound. if its a relatively young scar (less than 3-6 months) try mederma...rub it on the scar 3-4 times a day. if its older use silicone pressure patches. they're over the counter and easy to use...neosporin makes a great patch, called scar solutions i think...Curad also makes one under scar therapy. they're relatively inexpensive, as far as treatments go. just put the patch on the scar and keep it on for 12-24 hours, and it's waterproof! this is the treatment i used, along with injections for a year, after a major surgery. my keloid is relatively flat and still soft, and its now 4 years old. hope this was helpful
