JiYu products are sold exclusively through jiyuskin.com, Amazon (sold by JiYu Skincare), and TikTok Shop (@jiyuskin). Any other website, third-party seller, or social store claiming to sell JiYu is unauthorized and not affiliated with JiYu in any way. This matters more than it might seem. Unauthorized sellers operate entirely outside our supply chain, which means we have no visibility into what is actually in those products, how they’ve been stored, or whether they meet any safety standard. We can only stand behind what comes directly from us.

We are actively pursuing legal action against unauthorized sellers. If you’re unsure whether a seller is legitimate, contact us at support@jiyuskin.com before purchasing.

Most K-beauty brands are built around hydration and barrier support and they do that beautifully. JiYu goes further. We combine Korean formulation precision with longevity-based ingredients. We compound that work at the cellular level to repair, rebuild, and extend healthy skin function. It’s a direction the rest of the industry hasn’t caught up to yet. New formulas are in development and will be here soon!

Yes. Our formulas are designed to be gentle. If you’re reactive, we always suggest a patch test first.

Most customers notice healthier glow and smoother texture within 1–2 weeks. Dark spots and fine lines continue to improve with consistent use over 4–8 weeks.

Every JiYu product goes through multiple layers of testing before it ever reaches you. Our manufacturing partners, among the world's leading cosmetic ODMs, operates under full CGMP, ISO 9001, ISO 14001, ISO 22716 cosmetics GMP certification, ECOCERT and quality control protocols that meet both Korean MFDS and U.S. FDA cosmetic requirements. Every formula is dermatologist-tested, clinically evaluated, and required to meet both Korean Ministry of Food and Drug Safety standards and US FDA requirements. Skin safety, stability, and efficacy testing are conducted prior to production. Not as a marketing step, but as a non-negotiable requirement of our manufacturing process.

Yes — in every way that matters. JiYu was built on Korean skincare science, formulated by Korean researchers and manufactured in South Korea at one of the world's leading cosmetic facilities. Every product meets Korean cosmetic safety standards as well as US FDA requirements.

Most skincare works on the surface hydrating, brightening, smoothing what you can see. Longevity-based ingredients go deeper. They come from longevity medicine research, the science of what keeps cells healthy, functional and resilient over time. They work at the cellular level to support how skin actually repairs, regenerates, and ages from within. This distinction matters because surface-level results fade while cellular-level results compound. Korean skincare already leads the world in formulation science and active ingredient development. Pairing that precision with longevity-focused actives is the logical next step and one most of the industry hasn’t taken yet. NAD+, for example, is a molecule found naturally in every cell of the body that drives energy production and cellular repair, and declines significantly with age. JiYu pairs actives like these with Korean cosmetic precision to make them perform at their highest level.
