Learn the differences between atrophic scars, hypertrophic scars, and keloids. Discover how Dermapen microneedling stimulates collagen to improve acne scars and skin texture.
A scar is new tissue that forms when the skin repairs damage caused by injuries, surgery, acne, burns, or other types of trauma.
When the skin is injured, the body naturally produces collagen to close and repair the damaged area. However, the collagen produced during the healing process is arranged differently from normal skin. As a result, scars often have a different texture, color, and appearance compared to the surrounding skin.
Before choosing a treatment, it's important to first understand the type of scar you have, as different scars require different treatment approaches.
Understanding the different types of scars is essential because each type responds differently to treatment.
Atrophic scars are depressed or sunken scars that sit below the surrounding skin surface. They develop when the body does not produce enough collagen during the wound healing process.
One of the most common examples of atrophic scars is acne scars, particularly ice pick scars, boxcar scars, and rolling scars.
Unlike atrophic scars, hypertrophic scars develop due to excess collagen production during healing. These scars appear raised, thick, and firm but remain confined within the boundaries of the original wound.
Although they may gradually improve over time, hypertrophic scars often require specific treatments to improve their appearance.
Keloids are also caused by excessive collagen production, but unlike hypertrophic scars, they grow beyond the borders of the original injury.
Keloids may continue to enlarge even after the wound has completely healed. Because their biological behavior differs from other types of scars, they often require a different treatment approach and should be evaluated by a qualified physician.
Dermapen is an advanced microneedling device that uses sterile micro-needles to create thousands of controlled microchannels in the skin.
Although this may sound simple, these controlled micro-injuries activate the body's natural wound-healing response. As the skin repairs itself, it increases the production of collagen and elastin, leading to collagen remodeling—the process of reorganizing collagen fibers into a healthier and more structured network.
Because atrophic scars develop as a result of insufficient collagen production during healing, stimulating new collagen with Dermapen may gradually improve the skin's texture, making scars appear smoother and less noticeable over time.
In addition to improving atrophic scars, Dermapen is commonly used to help address:
Acne scars
Uneven skin texture
Enlarged pores
Fine lines
Dull-looking skin
Because Dermapen works by stimulating the body's natural regenerative process, results are not immediate. Improvements typically develop gradually over several weeks to months, and the number of treatment sessions varies depending on each individual's skin condition and treatment goals.
Not all scars can be treated with the same procedure.
Dermapen is most commonly recommended for atrophic scars, particularly acne scars caused by collagen loss. Raised scars, such as hypertrophic scars and keloids, generally require different treatment strategies because they result from excessive collagen production rather than collagen deficiency.
For this reason, obtaining an accurate diagnosis is the first and most important step before starting any scar treatment. In many cases, earlier treatment may help achieve better outcomes.
