Can craters be cured with a dermapen? How does it heal?

  • Does the Dermapen work on cratering acne scars?"
  • I'd like to get a dermapen to treat my craters, but I want to know if it really works."

Hello, I am a doctor at Smart Skin Clinic.

Does anyone have any of these questions?

Even if you want to improve crater-like acne scars with a dermapen, you may be hesitant about treatment before the effect is clear.

In this article, I will explain in an easy-to-understand manner, based on the medical standpoint and my own experience, whether the Dermapen is effective in treating craters on the face caused by acne scars.


Conclusion: Dermapen is effective for craters.

To begin with, let me conclude.Dermapen treatment for acne scars with cratering is effective.

The reason is that the mechanism of cratering acne scars and the action of the dermapen match like gears.

However, it is essential for the doctor to assess the shape and condition of the crater and adjust the machine according to the symptoms.

From this point on, we will explain in detail why the Dermapen is "effective" in treating craters.

How the Dermapen works

Dermapen uses the skin's own repair function.

Can you imagine what the skin's repair function is?

For example, we have all fallen and scraped our knees or accidentally cut our fingers while cooking.

Unless the injury is very serious, the wound will naturally heal over time and return to normal skin.

This is related to the function of "fibroblasts" in the "dermis layer" of the skin.

What are fibroblasts?

Deep within the skin is the dermis layer, which contains fibroblasts. Fibroblasts produce collagen and elastin, which are necessary to keep the skin healthy and in good condition.

When deep wounds occur due to injury, these fibroblasts are stimulated and their function to produce collagen and elastin to repair the wounds and regenerate the skin is activated.

In dermapen treatment, a very fine-tipped needle is inserted into the skin, making a small hole and intentionally creating a wound to activate the skin's repair function.

Dermapen Mechanism of Action

Since the dermapen "can adjust the depth of needle penetration," the depth of the needle can be adjusted to reach the "dermis layer" where fibroblasts are located.

Why do craters form?

The epidermal layer of the skin has a "turnover" function, in which new cells are produced over a period of about four weeks and old cells are shed as scum. This turnover process allows acne and scars on the epidermis to heal.

However, if the body's immune system is weakened and acne does not heal well, worsens, or is scratched, acne damage can extend to the "dermis" layer, which is deeper than the epidermis layer.

The "dermis layer" does not have a turnover function. Instead, the increased collagen production hardens and wounds heal.

However, too much damage, dryness, poor circulation, or infection can cause the wound to not heal properly and the collagen is replaced by hard tissue called scar tissue.

This scar tissue pulls on the epidermis, causing a crater (concavity).

Once scar tissue forms in the dermis layer, no further changes can be expected. In order to improve craters, it is necessary to break up the scar tissue and inject drugs while stimulating fibroblasts with a dermapen or similar device.

How Dermapen works for craters

The following is a summary of how dermapen works and the causes of craters.

What is needed to improve crateringStrengths of Dermapen
Destroys scar tissue
Stimulates the skin's healing mechanism and restores normal skin
The depth of the needle can be adjusted to penetrate deep into the dermis, where scar tissue is located, and destroy scar tissue.
The needle can stimulate fibroblasts in the dermis layer to stimulate the production of collagen and elastin
After making a hole in the skin, the drug can be injected to enhance the therapeutic effect.
