Is exosome FDA-approved?
No. FDA has approved ZERO exosome products for any indication. Globally registered as COSMETIC ingredient. FDA issued Public Safety Notification (Dec 2019) and warning letters in 2024-2025 targeting IV exosome operators. 'FDA-approved exosome' marketing is factually incorrect.
Is exosome the same as stem cell therapy?
No. Exosomes are 30-150 nm extracellular vesicles — cell-free byproducts of MSC culture, NOT live cells. Regulatory categories and mechanisms differ. Calling exosome 'stem cell therapy' is biologically and regulatorily misleading.
Do you offer IV exosome?
No. We do not offer exosome in any form. IV exosome has no therapeutic evidence base, FDA enforcement actions, and a documented bacterial infection cluster. We would not recommend it at any clinic.
Does exosome replace minoxidil and finasteride?
No. First-line AGA is minoxidil 5% + finasteride 1 mg (Chen 2020). Exosome scalp adjunct is preliminary (non-inferior to PRP, 'data lacking' per Kost 2022). Exosome sits on top of established therapy, never replaces it.
Exosome vs PRP?
PRP is autologous (your own blood). Exosome is allogeneic (donor MSC culture). Estupiñán 2025 split-face: exosome NON-INFERIOR to PRP, not superior. Counterfeit Korean exosome circulates — ask for direct-distribution documentation if pursuing elsewhere.
One-trip exosome course?
Single-session skin protocols viable in a 3-day trip. Full 5-session scalp AGA course requires monthly intervals × 5 months — NOT single-trip and cannot be compressed.
Most serious risks?
(1) IV / systemic injection sterility — FDA enforcement + bacterial infection cluster. (2) Hypersensitivity to MSC-derived material. (3) Counterfeit product without verifiable sterility.
Why cosmetic registration, not drug?
No exosome product has completed the multi-phase RCT efficacy / safety data required for drug approval. Cosmetic pathway permits topical application without that data. Until drug-grade RCT data is filed, exosome remains cosmetic-pathway.
Realistic improvement?
Modest, on top of baseline therapy. Acne scars: 12.6 percentage point delta vs control (Kwon 2020). Photoaging: GAIS improvement (Park 2023, subjective scale). Hair: non-inferior to PRP. We do NOT use 'regrow' / 'cure' / 'permanent' / 'miracle' language.
Safety — systematic review evidence?
Topical safety signal is more favorable than IV. Total exposed-patient count is small. Queen & Avram 2024: 9 alopecia studies, 125 patients, 10 serious adverse events across broader dermatology literature.
Pricing in Seoul?
Delight does not offer it. Market reference (other clinics): skin adjunct ~₩300,000-₩600,000/session; scalp single ~₩200,000-₩600,000; 5-session package ~₩1,500,000-₩2,500,000.
Exosome for melasma?
Preliminary adjunct evidence only. Foundation remains topical therapy + strict SPF + trigger avoidance. We would not offer exosome as melasma standalone.
Why does Delight refuse exosome protocols?
Small RCT base, modest effect sizes, no drug approval, unsettled long-term safety. We prefer modalities with deeper evidence support. May change as evidence matures.
