Product Story

Frequently Asked Questions

Is this serum authentic and made in Japan?

Yes. The product is manufactured in Japan by TBC, a brand that follows Japanese manufacturing standards. The serum’s packaging lists the country of origin as Japan, and the formulation includes a proprietary FGF‑1 peptide that is unique to this market. This local production helps ensure the ingredients are sourced and handled according to Japanese quality controls, giving you confidence in its authenticity.

How should I apply the serum and how often?

Apply a few drops to clean, dry skin in the morning and evening. Gently massage until fully absorbed, then follow with your usual moisturizer. Because the formula contains an active peptide, using it twice daily maximises the stimulation of fibroblasts. Avoid the eye area, and store the bottle in the refrigerator after opening to keep the peptide stable.

What are the key ingredients and what do they do?

The serum’s main active is a proprietary FGF‑1 peptide (Hitorigopeptide‑13) that binds to fibroblast receptors, encouraging collagen and elastin production for smoother skin. It also contains a blend of moisturizing agents and antioxidants that support barrier function. The peptide is present at roughly double the concentration found in typical Japanese serums, aiming to boost visible firmness and texture.

How does shipping work and how long will the product stay fresh?

JapansPrime ships the serum directly from Japan using a temperature‑controlled service. Delivery takes 7‑14 business days, and each bottle includes a tracking number. The product is sealed with a cold‑chain guarantee and remains stable for at least six months when refrigerated after opening, ensuring the peptide stays active throughout its shelf life.

Do I need to refrigerate the serum after opening?

Yes. The formulation relies on a cold‑chain preservation method to keep the FGF‑1 peptide stable. Once opened, store the bottle in the refrigerator and keep the cap tightly closed. This helps maintain the peptide’s bioactivity and prevents degradation, which is essential for achieving the intended anti‑aging benefits.

Is this product suitable for specific dietary preferences like halal, vegan, or kosher?

The current ingredient list does not indicate halal, vegan, or kosher certification, and no official dietary status has been disclosed by the brand. If you require a product with verified dietary certifications, you may want to look for alternatives that clearly label their compliance. This serum focuses on peptide efficacy rather than specific dietary claims.
