LUMINIEL Y Q&A

LUMINIEL Y PATCH – Q&A

Q1. What is the LLLT technology applied to this product?
A1. Low-Level Light Therapy (LLLT) activates or suppresses specific biological responses through exposure to light within a particular wavelength range.
It is widely used in medicine for skin healing, regeneration, and pain reduction.
Short wavelengths (blue) help sterilization and inflammation reduction; amber light promotes collagen synthesis and elasticity; red light improves blood circulation and skin tone.
These effects make LLLT useful in dermatology, orthopedics, and ophthalmology.

Q2. Who is LinkOptics, the manufacturer of Luminiel?
A2. LinkOptics is a medical device manufacturer based on LLLT technology.
Since its founding in 2004, the company has conducted more than ten pre-clinical and clinical studies in cooperation with top hospitals in Korea, including Seoul National University Hospital, Chonnam National University Hospital, Dankook University Hospital, and Chosun University Hospital.
Through these trials, the company has developed products for skin regeneration, whitening, vitiligo treatment, pressure ulcer recovery, and pain reduction.
Because its products are developed from clinical research, they demonstrate superior functionality and safety compared to general beauty devices.

Q3. Clinical Trials Conducted – <Y Patch>
A3. The Department of Obstetrics and Gynecology at The Catholic Kwandong University International St. Mary’s Hospital (Prof. Su-Rim Kim’s team) conducted pre-clinical and clinical studies approved by the Korean Ministry of Food and Drug Safety over a two-year period.
The Luminiel Y Patch was tested for its effects and safety in improving unpleasant odor, dryness through moisturizing, inflammation relief, elasticity, and whitening.
Results confirmed significant improvements, including 62% reduction in Candida bacteria, 14% reduction in odor, and 19% increase in collagen production.

Q4. The Y Patch is a beauty device, not a medical device.
A4. Although the clinical trials were approved by the MFDS and conducted over two years, most vaginal inflammations originate inside the vagina.
While an internal probe-type device was considered for stronger therapeutic effect, it was determined that such a design would limit accessibility for general female users.
Thus, the Luminiel Y Patch was developed as an external pad-type beauty device.
Due to its structural characteristics, it is not intended for treating diseases such as vaginitis.
It is a clinically verified, safe beauty device designed for comfort and hygiene management.

Q5. Precautions and Possible Side Effects
A5. Although improvement effects are common, all medical and beauty technologies may have minor side effects.
LLLT uses visible wavelengths similar to sunlight and therefore has minimal risk.
The Y Patch is particularly beneficial for postpartum women in restoring the Y-zone condition.
However, during pregnancy, it should only be used after consulting a medical professional — not because of specific risks, but as a general precaution during pregnancy for all devices and products.

Q6. Reason for the Vibration Function
A6. Due to the special application area, a vibration feature was added so users can confirm operation.
When touching the square power area, the device activates with a slight vibration.
To turn it off, detach the square power module from the patch.

Q7. Common Malfunctions – <Y Patch>
A7. Some users report charging issues due to cable incompatibility.
Most USB Type-C cables work fine.
Occasionally (less than 1%), battery issues occur with the square control module.
If a malfunction occurs within one year, the battery will be replaced free of charge.

Q8. Cleaning After Use
A8. The Luminiel Y Patch pad can be washed with water or alcohol and may even be sterilized by boiling.
However, the square battery module must not be washed with water — it should only be wiped with alcohol when needed.

Q9. Key Advantages of Luminiel Y
A9. The Y Patch is especially beneficial for women who experience discomfort or difficulty managing Y-zone conditions.
However, many healthy women also use it simply to maintain freshness and comfort.
In Korea, the product shows a high repurchase rate — many users even purchase it again as gifts for their mothers or daughters.
Beyond functional benefits, it provides a warm, refreshing sensation after menstruation, which encourages continued use.
