"Domohorn Wrinkle" Case Study

■ Background of Introduction

For approximately 50 years, Saishunkan Pharmaceutical has emphasized "dialogue that stays close to each customer" through telephone. However, with the shift to online customer contact, the challenge of "difficulty grasping customers' skin conditions through a screen" became apparent. Traditional web questionnaires also presented problems, such as a heavy burden of input and reliance on subjective answers, making immediate and objective feedback difficult.

In response to this situation, Saishunkan Pharmaceutical began offering "Suhadabi Check" as a new touchpoint for easily understanding skin conditions. "Suhadabi Check" is designed as an intermediate touchpoint connecting web-based information acquisition with individual consultations via chat and phone with expert staff, and Perfect Corp.'s AI skin analysis technology is adopted for skin condition assessment.

Effects of Introduction

By quantifying skin conditions, it has enabled consultations with expert staff at optimal timings and highly personalized experiences. By using LINE, which is used daily, as an entry point, it has achieved both the promotion of new purchases and the continuous relationship building with existing customers.

First-time purchase rate more than doubled
The first-time purchase rate for "Suhadabi Check" users is more than double that of non-users. Objective numerical data has encouraged purchases.

Number of users more than tripled in approximately 1 year and 2 months
The monthly number of users increased from approximately 4,500 in November 2024, when operations began, to 14,257 in January 2026. Data-driven operations, such as optimizing the timing of skincare information delivery, contributed to this increase.

Contribution to sales
Contributed to cumulative sales of several hundred million yen within approximately one year of introduction.
*This is the result of combining multiple measures, including support via chat and phone.

Improved customer engagement
Approximately 60% of users (approximately 8,800 people as of January 2026) are existing members, indicating established continuous use.

Reactivation of dormant customers
It functions as an opportunity to encourage repurchases from customers who had not made purchases for a long period.

Increased brand trust
By combining AI-based quantification with expert staff support, customer trust has been strengthened.
