In time, some collagen breaks down at the site of the wound and the blood supply reduces. The scar gradually becomes smoother and softer. Although scars are permanent, they can fade over a period of up to 2 years. It's unlikely they'll fade any more after this time.
A scar may fade so much that you can barely see it, but it never completely goes away. Some scars cause problems months or years later. As nerve endings grow back, the scar may become painful or itchy. Skin cancer can develop in scars, especially in burn scars.
Once there is a scar, it is forever. Generally, it will blend into the normal skin creases so that it is hardly noticeable. Most scars reach this point six months after surgery. It can take up to two years for some severe scars to fully develop.
How long does it take for untreated scars to fade? Depending on the scar type, scars can take up to two years to fade naturally. After the two-year mark, it's unlikely your scar will fade anymore. Scarring is a natural part of the healing process following tissue damage.
After a scar is first formed, the body continues to touch up its work where it can - which is why scars fade slightly over the years when left alone. But scar tissue does not get replaced by this process2, which means that most scars, when left to heal naturally, will never fully disappear.
Scar tissue is usually red at first, then pink for 3-6 months and then fades to a slightly lighter than normal skin color. Exposure to heavy sunlight may cause a scar to heal darker. Sun avoidance and use of sunscreen over scar sites is advisable for six months after surgery.
Hypertrophic Scars – Raised scars that remain within the boundaries of the initial injury, incision or trauma, hypertrophic scars can be red and raised enough to be readily noticeable. In some cases, hypertrophic scars will fade over time on their own. Other times, they'll require more aggressive treatment to erase.
The scar will be slightly higher than the surrounding skin. During the scar healing process, the color of the scar will fade and its volume will decrease. This stage lasts for an average of 3 to 6 months. The scar then enters its final phase when it begins to become paler and softer (remodeling).
There are four main types of scar which form differently and require different treatments. Old scars are harder to treat, but their appearance can be reduced over time.
The scar will appear to become more lumpy and redder at first. This process will take between two and six weeks. Between approximately four and eight weeks the scar will look much wider and redder than it did initially. This is usually the worst the scar will look, and this is a natural part of the healing process.
Bio-Oil helps to improve the appearance of new or old scars; whether from surgery, accidents, burns, insect bites, scratches or conditions such as acne or chickenpox. Although younger scars will have a greater chance of improvement, studies have shown that older scars also benefit from regular use of Bio-Oil.
Excessive pulling or tension across a healing wound is increasingly implicated as a factor which may increase inflammation and scar formation. An environmental factor that clearly has an effect on the appearance on skin scarring is sunlight exposure.
Conclusions: Scar redness fades on average at 7 months. This is influenced by the wound type and position. The authors advocate the use of the term "rubor perseverans" to describe the physiologic redness of a normal scar as it matures beyond the first month, a process that does not involve inflammation.
Facial scars on men are seen as attractive to women but only under certain circumstances — they are signs of bravery and health. Women find small facial scars attractive when looking for a short-term relationship, research finds. Previously it was thought facial scars made men look less attractive in this context.
Time Heals
According to the National Institutes of Health, it takes between two and three years for scars to turn pale and the skin to mature.
Hypertrophic scars occur when there is a lot of tension around a healing wound. These scars are thick and raised, and often red in color. They may remain like this for several years. Hypertrophic scars are the result of an imbalance in collagen at the site of the wound.
It can take up to 12-18 months after your injury or operation for a scar to heal. A normal scar will become darker initially and after a period of time this will start to fade. Dark scars can remain for years or indefinitely in people with darker skin.
Hypertrophic scars that result from burn wounds are more difficult to treat. Superficial burn wounds usually heal without forming hypertrophic scars. Deep burn wounds are harder to treat. Many dermatologic and plastic surgeons treat these by removing the burned area and then using a skin graft.
One tip for taking care of scars is to use a topical ointment. Cocoa butter cream and Vaseline are most often used to help reduce the appearance of scars. Applying the ointment daily will help heal scars but will not make them invisible.
Laser or light therapy (pulses of light) can reduce the redness in a scar by targeting the blood vessels in the excess scar tissue. For some pitted scars, laser surgery (laser resurfacing) is used to try to make the scar flatter.
Wound healing is classically divided into 4 stages: (A) hemostasis, (B) inflammation, (C) proliferation, and (D) remodeling. Each stage is characterized by key molecular and cellular events and is coordinated by a host of secreted factors that are recognized and released by the cells of the wounding response.
Type 3 skin has a higher scarring potential than Type 1 or 2. Type 4 skin is described as olive or caramel toned, typically with hazel or brown eyes and dark hair. Type 4 skin tans very easily and may still burn with long sun exposure. Type 4 skin scars easily.
Two of the most common types are hypertrophic and keloid scarring, both of which experience excessive stiff collagen bundled growth overextending the tissue, blocking off regeneration of tissues. Another form is atrophic scarring (sunken scarring), which also has an overexpression of collagen blocking regeneration.
