There is a difference in effectiveness depending on the amount (concentration) of the mixture. The higher the concentration, the better the effect, but we believe that there is a limit depending on the penetration (absorption) of each individual. Please refer to "Directions for Use" for recommended guidelines.

Intravenous drip is most effective. Mucosal absorption in the nose or under the tongue, water light injections, derma-rollers, and micro-needles are also considered highly effective. C-retour, which is applied directly to the skin, is also highly effective because it is kept fresh by refrigerated storage. Since the use of equipment, medical treatment, and esthetic treatment are expensive, please try our daily "self-esthetics" first.

Cytokines (growth factors) deteriorate rapidly in environments above 18 degrees Celsius. To slow down the deterioration of cytokines (growth factors), we recommend storing the product under refrigeration. If you are traveling or staying out of the house for an extended period of time, please consider carrying the product in small portions or using refrigerants.

Since it is provided in a vacuum container, there is no expiration date until the freeze-dried product is unsealed. After unsealing, we recommend using the product within one month, as it will gradually deteriorate due to exposure to air.

With continuous use, the effect of the product will increase. By using it habitually twice a day, you can experience the improvement of skin / hair quality. [Estimated time to feel the effect] Essence: 1 month Scalp serum: 2 months *Depends on its concentration and frequency

It can be used in IV drips and is non-toxic. There have been no reports of accidents, so please feel free to use it.
