TheraFill is a high-purity Atelocollagen injectable from Korea — pure collagen with the immunogenic Telopeptide region enzymatically removed (Telocollagen → Atelocollagen via Protease). Used both as a deep-wrinkle filler AND a collagen-stimulating skin booster.
The molecular structure is identical to your own dermal collagen, which is why it integrates rather than 'filling' as a foreign body. Korean MFDS approved with US FDA-cleared collagen sources used in production.

Research-informed guidance for this treatment type. Your doctor’s written plan after assessment always takes priority.
Before your appointment
- Tell the doctor about allergies, infection or inflammation, bleeding tendency, medicines and supplements, immune conditions, prior implants or filler, and pregnancy or breastfeeding.
- Confirm the exact product and whether the treatment plan requires product-specific massage; do not assume all biostimulators have the same aftercare.
After treatment
- Keep the sites clean and avoid pressing or massage unless the written product-specific plan instructs it.
- Use gentle skincare and ask when to resume makeup, exercise, heat exposure and active products.
- Keep the product record and attend the planned review.
What may be expected
- Temporary bumps, swelling, redness, tenderness or bruising may occur; the expected timeline differs by formulation and injection depth.
Contact us promptly
- Contact the clinic for persistent nodules, increasing heat or redness, drainage, fever, or delayed inflammation.
- Seek urgent care for unusual pain, marked skin-colour change, vision change or neurological symptoms.
1:1 follow-up
Before you leave, the team records your treatment, expected recovery, follow-up timing and direct contact path. A doctor reviews concerns when needed.
