We’ve also summarized the main steps involved in the procedure, so please use this as a reference for your future plans.
What Is a Dermapen? An Explanation of the Expected Results
First, I’ll explain in detail how the Dermapen works, the results you can expect, and the downtime involved.
■How the Dermapen Works and the Skin Regeneration Process
The Dermapen is a cosmetic medical device that promotes skin regeneration by harnessing the skin’s wound-healing response, and it has been adopted by many clinics in Hiroshima. Recently, the device known as the “Dermapen 4” has been attracting a lot of attention. This treatment uses ultra-fine needles—thinner than a strand of hair—to intentionally create up to 1,920 microscopic holes per second on the skin’s surface.
When tiny holes form in the skin, the skin begins to activate its “wound-healing ability” to repair the damage. ThisBy activating the skin's natural healing process, the production of collagen and elastin—which support the skin's elasticity and hydration—is promotedIn addition to this, during the wound healing process,Various growth factors are released and activatedThis treatment helps unlock the skin’s natural regenerative power, leading to healthier skin. As a result, the Dermapen is a popular treatment not only among women but also in men’s skincare across Japan, including Hiroshima.
■ Expected Benefits for Acne Scars, Enlarged Pores, and Fine Lines
Dermapen is a cosmetic procedure that can address a wide range of skin concerns, such as the following.
- Crater-like acne scars
- Post-inflammatory hyperpigmentation (acne scars) and dullness (*May not be suitable for certain types of dark spots, such as melasma)
- Enlarged Pores (Sagging Pores, Pores Enlarged by Sebum)
- Fine lines, mild sagging
For crater-like acne scars, it is believed that subtle stimulation of the dermis promotes a wound-healing response and activates collagen production. As a result,It is expected to help make skin imperfections less noticeableThe first is the "I" in the "I" column.
In addition, by promoting skin turnover, it may help reduce post-inflammatory hyperpigmentation and dullness (*Note: Caution is advised, as it may worsen melasma).
When it comes to concerns about pores, promoting collagen production is expected to improve firmness around the pores, making pores that are prominent due to sagging appear tighter.
The Dermapen works not only on the skin's surface but alsoBecause it targets the dermis—the foundation of the skin—it is one of the treatments that can address a wide range of skin concerns.It is.
■Post-Treatment Downtime and Risks
After a Dermapen treatment, there is a period of downtime while the skin recovers. The duration of downtime varies depending on the treatment and skin type, butRedness and stinging usually subside within about 1 to 3 days, and peeling usually subsides within about 3 to 5 days., depending on the type of treatment,It can sometimes last for about a week.It’s important to understand this. However, since the severity of symptoms and the recovery period vary from person to person, it’s important to follow your doctor’s instructions for aftercare.
In rare cases, internal bleeding, post-inflammatory hyperpigmentation (PIH), or infection may occur. Additionally, caution is advised, as symptoms may worsen in individuals with melasma. Punctate bleeding and bruising usually subside on their own within about a week; however, if you experience severe pain or swelling that persists for an extended period, please consult the clinic where you received the treatment immediately.
No Mistakes! 3 Tips for Choosing a Dermapen Clinic in Hiroshima
There are many clinics in the Hiroshima area that offer Dermapen treatments, so there are plenty of options to choose from. As a result, some people may find themselves wondering, “Which clinic should I choose?” With that in mind, here are three key points to consider when selecting a clinic.
■Are the pricing plans for each treatment clear and make it easy to visit regularly?
Since Dermapen pricing varies by clinic even in Hiroshima, be sure to check whether the rates are clearly listed on the official website or similar sources.
In addition to the basic fee, the following are some of the costs you should check in advance.
- cost of anesthesia
- Treatment Fee
- Cost of optional medications used
For example, anesthesia fees typically range from 2,000 to 5,000 yen per session, though some clinics may include this in their base fee. Knowing the total cost of the procedure in advance will help you feel more at ease during your treatment.
While you may notice satisfying results after just one Dermapen treatment, depending on your desired outcome and skin condition,It is generally recommended to undergo multiple treatments—about 3 to 5 times per month (or 5 to 10 times in severe cases).That’s why clinics that offer both pay-as-you-go options and multi-session packages allow you to attend treatments at your own pace without feeling overwhelmed. Typically, the per-session cost for package plans is lower than the pay-as-you-go rate.
■Are there any optional treatments available that address my specific skin concerns?
It is believed that the micro-pores created by the Dermapen allow active ingredients to penetrate deeper into the skin, and adding an optional treatment that delivers active ingredients tailored to your specific skin concerns can make the procedure even more effective.
We’ve selected seven topical solutions used with the Dermapen at beauty clinics and will introduce the characteristics of each one.
