Youthfill: hyaluronic acid fillers from RFBio
Youthfill is a range of cross-linked hyaluronic acid (HA) dermal fillers from RFBio, a South Korean company. RFBio makes the range with its own HoPE technology and lists the gels at 24 mg/mL of cross-linked HA with 0.3% lidocaine for comfort.
This listing carries three gels, from the lightest to the firmest. Fine is injected into the superficial dermis for fine lines and for the lips. Deep is placed in the deeper dermis for medium-to-deep lines such as the nasolabial folds, and for lip and cheek volume. Shape is the firmest gel and is placed in the deep subcutaneous layer for volume and contouring of the cheekbones, chin and jawline.
The old listing describes a low injection force, which supports a smooth, controlled application. Select the gel you need using the options above the add-to-cart button.

Why practitioners choose Youthfill
Fine, Deep and Shape cover fine lines, deeper folds, lips and contouring from one Korean product family.
The gels contain 0.3% lidocaine to reduce discomfort during injection.
The listing describes a low injection force, which supports smooth, controlled placement.
RFBio makes the range with its own HoPE technology, which the company describes as giving a uniform gel.
The gel is biodegradable, so the body gradually breaks it down. Hyaluronidase is available to dissolve HA fillers if needed.

What each component does
Cross-linked hyaluronic acid, 24 mg/mL
Hyaluronic acid is a sugar found naturally in skin, where it binds water. In a filler it is cross-linked so that it lasts longer than natural HA before the body breaks it down. Youthfill is listed at 24 mg/mL, and the three gels differ in how firm they are.
Lidocaine, 0.3%
Lidocaine hydrochloride at 0.3% is included for comfort during injection. It is a local anaesthetic. Screen patients for lidocaine allergy, and check the carton to confirm the ingredients of your syringe.
Which gel for which area
- Fine: fine lines and the lips, injected into the superficial dermis.
- Deep: medium-to-deep lines such as the nasolabial folds, and lip and cheek volume, injected into the deeper dermis.
- Shape: volume and contouring of the cheekbones, chin and jawline, injected into the deep subcutaneous layer.
Approved indications differ by market. Confirm them in the instructions for use for your country.
How Youthfill is used
Reference information for trained practitioners. The manufacturer’s instructions for use for the specific gel and your training take precedence over this page.
Step by step
-
Assess and consent
Review medical history, allergies (including to lidocaine), medication, bleeding risk, previous fillers and the patient’s goals. Explain the expected result, the risks and the possibility of needing hyaluronidase.
-
Choose the gel
Select Fine, Deep or Shape according to the area, depth and result needed, following the instructions for use.
-
Prepare the skin
Remove make-up and cleanse. Mark the treatment area and apply topical anaesthetic if required.
-
Inspect the syringe
Check the packaging, seal and expiry. Use the sterile needle supplied or a needle or cannula recommended in the instructions for use.
-
Inject as taught
Fine is injected into the superficial dermis, Deep into the deeper dermis and Shape into the deep subcutaneous layer, using the technique in the instructions for use and your training. Inject slowly and with low pressure, and stop at once if the patient reports unexpected pain or you see blanching.
-
Review
Assess the result, mould gently if the technique requires it, and plan any review according to the gel used and the area treated. Volume effects are visible straight after injection.
Administration notes
Know the risks of the area. Filler can cause vascular occlusion. Practitioners should know the anatomy of the area, recognise the signs early and have hyaluronidase and an emergency protocol immediately available.
- Single use. One syringe, one patient. Discard any remainder with the needle.
- Do not inject into infected, inflamed or broken skin.
- Do not use in patients allergic to hyaluronic acid or lidocaine.
- Dispose of needles into a sharps container in line with local clinical waste rules.
After treatment
- Redness, swelling, tenderness and bruising are common and settle within days
- Avoid strenuous exercise, heat, saunas and alcohol for about 24 to 48 hours
- Seek urgent review for severe pain, blanching, skin colour change, visual change or a lump that grows or becomes tender
