How does dermaroller help in treating scars?
Dermaroller and treatment of scars! Imagine what happens if a tear falls from your eye on a small piece of your silk clothing, you will notice a difference in its shape, the same thing happens with the skin, any burn, injury or surgery can cause a scar in the skin. The scar is not bad if it is small or in a place that can be hidden, but if it is different, you may be wondering about ways to treat, so there is no need to worry. In this article, we will review with you what a scar is, and one of the ways to treat it is the microneedling technique using the dermaroller DRS.

How do scars form?
A scar forms as a normal part of the healing process after an injury to the skin. The shape and severity of the scar depends on several factors, including the depth and size of the wound, the location of the injury, age and gender. The scar forms when the second layer of skin (the dermis) is damaged, and the body forms collagen fibers to repair the damage.

Scar types
There are several different types of scars and they are as follows:

Keloid scars: An uncommon type and the result of a very aggressive healing process, where fibrous tissue (scar tissue) forms over the wound to repair the injury, and in some cases, additional scar tissue called keloids form.
Bullous scars: They usually appear after a burn, and they cause tightening of the skin, and may deepen and affect the muscles and nerves.
Hypertrophic scars: raised, red scars that resemble keloids but do not extend beyond the site of the injury.
Acne scars: caused by severe acne, and range from deep pits to wave-like scars in appearance.
Stretch marks: They often occur after pregnancy, puberty, or after weight gain or loss.
Can scars be treated with a dermaroller?
Microneedling using a dermaroller can help make the scar smaller, or less noticeable, and may be recommended by a specialist doctor. The treatment of scars depends on several factors, including:

The type, size and location of the scar.
Your age and the age of the scar.
Whether the scar is painful or causing you problems.

Dermaroller scar treatment uses small, sterile needles to prick your skin with numerous micro-punctures, thereby stimulating collagen production that smooths out scars and improves damaged skin texture. Multiple sessions of minimally invasive microneedling are an effective treatment for atrophic scars that follow acne. It stimulates the skin repair process, in addition to the advantage of being a relatively risk-free procedure.

Some studies have reported that microneedling stimulates natural wound healing, and this occurs in three stages:

The first stage: the stage of post-acupuncture inflammation, and the platelets release chemical agents that cause more platelets to invade the treatment area.
The second stage: the stage of proliferation and the release of many growth factors, the proliferation of fibroblasts, then the keratinocytes begin to promote the production of laminin and collagen.
The third stage: the rebuilding stage and lasts for months after the injury (acupuncture) and is caused by fibroblasts.

The clinical evaluation of some cases who underwent micro-needling, after several sessions for three months of treatment, showed a good improvement in the appearance of the scar, and a moderate improvement in the skin texture, as the scar tissue shrinks, pigmentation begins to fade, and the density of the skin increases, which leads to skin tightening. It makes the scars less visible.

With continued sessions and treatment using the dermaroller, most of the scar tissue will be removed and replaced with soft, smooth and healthy skin.

Finally…

Treating scars is a major challenge, and microneedling and the use of the DRS dermaroller is a new addition to scar treatment methods, with the advantage of being non-threatening, in addition to short recovery time, and leading a normal life.
