Dermaroller Japan held a media seminar on the latest trends in aesthetic medicine and microneedling in Tokyo on July 30, 2026. Dermatologist Dr. Satoko Takase served as the speaker, explaining new directions in aesthetic medicine and new perspectives in microneedling research.
The trend in aesthetic medicine: the idea of "nurturing the skin"
Dr. Satoko Takase explained that aesthetic medicine in recent years has expanded beyond treating individual concerns such as "removing spots" or "improving wrinkles" to "skin nurturing and regenerative aesthetics," which continuously improve the condition of the skin as a whole.
Emphasis is placed on improving the overall quality of the skin: glow, firmness, texture, pores, and translucency. The idea of "layering" was also introduced, in which the skin is viewed as layers such as the epidermis, dermis, and subcutaneous tissue, and treatments suited to each purpose are combined.
The talk described a shift in thinking: aesthetic medicine is not "finished once treated," but is about continuously observing and adjusting the condition of the skin.
The "cell-to-cell communication" perspective in microneedling research
New perspectives in research were presented on microneedling technology, which has been used in aesthetic dermatology for more than 20 years.
In addition to the conventional mechanism of "creating tiny wounds and using the wound-healing response," research in recent years has been advancing with a focus on "cell-to-cell communication" among cells such as keratinocytes and fibroblasts.
The seminar introduced new research perspectives, such as signal transmission between cells triggered by the fine stimulation of microneedling. In 2025, a Japanese research group published in Nature Communications a study focusing on the relationship between keratinocytes and dermal collagen formation, and research on interactions between cells in skin regeneration continues.
*The above research is not a study that directly verifies the effectiveness or performance of microneedling or the "Dermaroller HC902." At this seminar, it was introduced as one example of research trends in dermatology and cell-to-cell communication.
A new perspective on stimulation strength: "Low Injury × Frequency"
The strength of stimulation in microneedling was also discussed. The view presented was that deep stimulation or strong inflammation does not always lead to good results.
With excessive stimulation, risks such as post-inflammatory hyperpigmentation (PIH), infection, and effects on the skin barrier should be considered. Therefore, instead of pursuing only "High Injury" (stronger invasiveness), the perspective of "Low Injury × Frequency" (minimally invasive stimulation and consistency) was introduced.
The importance of appropriately considering the degree and frequency of stimulation according to the condition of the skin and the purpose was explained. This does not indicate the effect or performance of any specific product; it was introduced as a research and clinical perspective for thinking about aesthetic medicine, including microneedling.
Aesthetic medicine knowledge to use in everyday self-care
After the lecture, Dermaroller Japan gave a product presentation of the "Dermaroller HC902," a home-care microneedle roller notified in Japan as a medical device.
The product's structure, how to use it, and precautions for hygiene management were explained, and participants had the chance to handle the product themselves. Questions about use on the face, neck, scalp, and other areas were also raised, and lively discussion took place.
Media attendees shared impressions such as "I'd like to start with scalp care," "The content was easy to understand and gave me a chance to learn about aesthetic medicine today," and "I'd like to deepen my understanding by actually using it."
By continuing to share not only product information but also research on microneedling, trends in aesthetic medicine, and proper usage and precautions, Dermaroller Japan aims to create an environment where users can approach the product based on correct knowledge.
Comment from Masato Iwata, CEO of Dermaroller Japan
Masato Iwata, CEO of Dermaroller Japan, commented that microneedling has been researched and used for more than 20 years, while research to understand its mechanism continues to advance.
In aesthetic medicine as well, he said, the idea of "skin nurturing" is spreading: rather than seeking change through a single strong treatment, people engage with their skin continuously while understanding its condition.
The company believes that, beyond selling Dermaroller, continuing to share information so that people can learn about microneedling correctly is an important role for the brand. It says it will keep learning from doctors and specialists and deliver accurate, easy-to-understand information.
