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.

Preparation and aftercare for TheraFill — High-Purity Atelocollagen

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.

Common questions
TheraFill vs HA filler — which is better for under-eye?+
TheraFill is often preferred for the tear-trough because there is no Tyndall-effect blue tinge risk (a known issue with HA fillers in thin under-eye skin). The collagen integrates with the dermis rather than sitting as a discrete bolus. Some patients combine: TheraFill for deep tear-trough + HA for surface contour.
Is TheraFill safe for animal-derived-product-sensitive patients?+
TheraFill is porcine-derived collagen with the Telopeptide region removed (the immunogenic part). Allergy reactions are rare but a 24h skin patch test is standard for first-time patients. Not Halal-certified — patients with religious considerations should request Sculptra (PLLA, fully synthetic) or Profhilo (HA, bacterial fermentation) as alternatives.
How does it compare with bovine collagen products?+
Atelocollagen has the immunogenic Telopeptide removed enzymatically, so allergy rates are dramatically lower than older bovine collagen products. The molecular structure is also closer to native human dermal collagen.
Is TheraFill — High-Purity Atelocollagen halal-friendly?+
No. Contains porcine-derived atelocollagen. NOT halal — porcine source is haram under all scholarly opinions. We state this plainly rather than let you find out afterwards — ask at consultation and the physician can go through an alternative that meets your requirement. This reflects the ingredients used, not a halal certification.
What happens during a TheraFill session?+
Consultation + skin test — Allergy patch test 24h prior is recommended for first-time atelocollagen patients. Topical numbing — Cream applied 20 minutes before injection. Micro-injection — Fine needle delivery using either filler-style boluses (deep wrinkles) or skin-booster micro-droplet pattern. Cooling + after-care — Cold pack 5 minutes; avoid alcohol 24h, sun 1 week. A physician assesses your face first and sets the plan; what is done and where follows from that assessment.
Who is a good candidate for TheraFill?+
Generally considered for: Under-eye hollowness (tear-trough) · Deep nasolabial folds · Patients with HA hypersensitivity or wanting non-HA option · Skin booster patients seeking stronger collagen response than pure HA boosters. Whether it suits you is decided by a physician at assessment, and there are people for whom it is not advised.
3 more questions+
Does TheraFill hurt?+
Anaesthesia for this treatment: Topical. A session runs about 30–45 minutes. How much a person feels varies, and anything that concerns you is worth raising at assessment.
What is the recovery like after TheraFill?+
Downtime: Mild swelling 1–2 days. How quickly this settles varies from person to person; ask your physician before planning anything that depends on the date.
How many sessions before I see results?+
Immediate volume from day 1; collagen effect peaks at 6 weeks; lasts 6–12 months depending on indication. 2–3 sessions 4 weeks apart recommended for optimal collagen response.
