It's all relative. : Scars last forever. They don't go away. The amount of collagen peaks after a few weeks and is remodeled, but the scar is permanent.
Dr. Subramaniam Arumugam
Plastic Surgery 56 years experience
Old = Matured: Old means = fully matured -when the skin continuity is broken by a cut by surgery or by injury > body forms scar tissue to unite the ends. There are three stages of the scar 1 stage of healing (two weeks) 2. During the next eight weeks (proliferative stage) the scar overgrows and the scar is red, raised and lumpy 3. Maturing stage-scar becomes soft, pale and flat-6 to 12 months (longer in children).
Dr. Joseph Mele
Plastic Surgery 32 years experience
Mature?: An injury causes a long cascade of events that promotes healing and eventually leads to a mature, stable scar. For adults the process takes a year on average, with a range of 6 moths to 2 years. For young children the average amount of time to form a mature scar is 2 years.
Dr. Keimun Slaughter
Facial Plastic Surgery 12 years experience
1 year: Scars typically reach full maturation or are considered "old" after 1 year. The remodeling pathway can continue up to 18 months however, the changes are usually more on a microscopic/histologic level and do not translate to anything that can be seen by the naked eye. You can assume that at the year mark, this is basically the final appearance of the scar.

Can the cracks heal and form scars that will obstruct the milk ducts?

Usually cracks heal: I recommend lanolin cream. After nursing, rub your breast milk on your nipples and allow it to dry. Your breasts need "air time." leaving them open to oxygen will help the healing process.
A 21-year-old member asked:

Will impetigo leave scars?

2 doctor answers3 doctors weighed in
Dr. Robert Kwok
Pediatrics 33 years experience
Temporary changes: Impetigo usually affects the upper outer layer of skin, so there should not be noticeable scars after the color changes even out over a year or so. If the patient scratched at the scabs during healing, and made deeper wounds, then permanent mild scars can occur (just like in chicken pox, where scars normally don't occur unless the scabs are scratched off by the patient).

Will a scar from pityriasis heal?

3 doctor answers6 doctors weighed in
Dr. Morris Westfried
Dermatology 46 years experience
Yes: Pityriasis does not leave scars. It usually does not even leave color change. First confirm that the diagnosis is correct, and treat the area with prescription creams to heal the area. If there is a depressed scar it can be improved with fractionated laser treatment either co2 or erbium depending on your skin color.

How do scars develop on corneas?

2 doctor answers3 doctors weighed in
Dr. Robert Kwok
Pediatrics 33 years experience
From deeper injuries: A scar can form on a cornea after a corneal ulcer or corneal erosion, because the injury goes deeper, beyond the surface layer of cells. A corneal abrasion injures just the top layer of cells, and usually heals in 1-2 days without a scar. For the deeper injuries, sometimes steroid eye drops are used later in the healing period to help decrease scar formation.
