1.Wrinkle-related Clinical Study
Biohacking that addresses both wrinkles and dermal density
In the group using the nutritive ampoule and device together, eye-area wrinkles were significantly reduced after 2 and 4 weeks, while dermal density was significantly increased after 2 and 4 weeks.
The simultaneous-use group also showed significant improvement compared to ampoule-only use, demonstrating strong persuasive value in terms of delivery efficiency and tissue-condition improvement.
Ampoule + Device Combined Use
Approximately 2–3x greater improvement compared to ampoule-only use
Approximately 25% improvement in eye-area wrinkles
Approximately 30% increase in dermal density
Ampoule-Only Use
Approximately 8% improvement in eye-area wrinkles
Approximately 10% increase in dermal density
2.Brightening-related Clinical Study
A brightening ritual that enhances the appearance of dullness
In the group using the brightening ampoule and device together, skin melanin was significantly reduced after 2 and 4 weeks, and skin tone was significantly improved after 2 and 4 weeks. In particular, at the 4-week point, the simultaneous-use group showed a significant difference compared to the ampoule-only group, confirming its potential as a brightening program.
Ampoule + Device Combined Use
Approximately 1.3–2x greater improvement compared to ampoule-only use
Approximately 28% reduction in melanin
Approximately 25% improvement in skin tone
Ampoule-Only Use
Approximately 10% reduction in melanin
Approximately 8% improvement in skin tone
3.Moisture-related Clinical Study
Enhancing immediate sensorial results in a moisture ritual
In the group using the hydration ampoule and device together, both skin surface moisture and inner skin moisture improved, with inner skin moisture showing a significant increase after 2 and 4 weeks. This demonstrates strong potential for use in after-care and skin-condition programs where moisture and recovery sensorially are important.
Ampoule + Device Combined Use
Approximately 1.8–2.3x greater improvement compared to ampoule-only use
Approximately 35% increase in skin surface moisture
Approximately 45% increase in inner skin moisture
Ampoule-Only Use
Approximately 12% increase in skin surface moisture
Approximately 15% increase in inner skin moisture
Clinical and Research Evidence
1. Research Report [PNK-17501-M1R]: A 4-week human application study before and after use on improvement of skin surface moisture and inner skin moisture using a cosmetic absorption-inducing skin stimulation device
Key Evidence: In a 4-week human application study conducted on 22 women aged 19–55, simultaneous use of an ampoule
and device confirmed statistically significant improvement in skin surface moisture and inner skin moisture after 4 weeks compared to ampoule use alone.

3. Research Report [PPNK-17501-K1R]: A 4-week human application study on improvement of eye-area wrinkles and dermal density using a cosmetic absorption-inducing skin stimulation device
Key Evidence: In a 4-week human application study conducted on 20 women aged 19–55, both ampoule-only use and
simultaneous use of an ampoule and cosmetic absorption-inducing skin stimulation device confirmed statistically significant improvement in reduction of eye-area wrinkles and increase in dermal density. In particular, simultaneous use of an ampoule and device confirmed statistically significant differences in eye-area wrinkles and dermal density after 2 weeks and 4 weeks compared to ampoule use alone.

4. Study on Skin Improvement Using MTS
Key Evidence: The skin care method combining Roller Gold and ampoule showed more effective results in moisture, pores, pigmentation, and redness improvement than ampoule-only use. In the study, both the experimental group and control group confirmed improvement even within a short period, and in particular, the experimental group using MTS together with an ampoule showed statistically significant effects in increased moisture content, pore reduction, and reduction of pigmentation and redness. The experimental group also showed higher scores in satisfaction after care.
