Sosum: hyaluronic acid fillers from JSBIO
Sosum is a range of cross-linked hyaluronic acid (HA) dermal fillers from JSBIO Co, Ltd., a South Korean company. The gels are listed at 20 mg/mL of cross-linked HA. JSBIO describes its LTSR process (Low Temperature Stabilization Reaction), a low-temperature cross-linking method intended to give a dense, finely dispersed gel.
This listing carries three gels, from the lightest to the firmest. Sosum S is injected into the upper dermis for fine lines. Sosum M is injected into the middle dermis for nasolabial folds, lip lines and marionette lines. Sosum H is the firmest gel and is placed in the deep dermis and subcutaneous layer for contouring.
Lidocaine content may differ between the gels and batches, so check the ingredient list on the carton for the syringe you receive. Select the gel using the options above the add-to-cart button.
The lightest gel, injected into the upper dermis for fine lines.
For nasolabial folds, lip lines and marionette lines in the middle dermis.
The firmest gel, placed in the deep dermis and subcutaneous layer for contouring.
Lidocaine content can differ between gels and batches, so confirm the ingredients on your syringe.
Why practitioners choose Sosum
S, M and H cover fine lines, folds and deeper contouring from one Korean product family.
JSBIO describes its Low Temperature Stabilization Reaction as a low-temperature cross-linking process intended to give a dense, finely dispersed gel.
Each gel is designed for a different injection depth, from the upper dermis to the subcutaneous layer.
The gel is biodegradable, so the body gradually breaks it down. Hyaluronidase is available to dissolve HA fillers if needed.
JSBIO Co, Ltd. makes the range in South Korea.

Sosum gels are medical devices for injection. Which indications are permitted and what training is required are set by the regulatory framework where you practise. Korea Filler Experts supplies the product. Nothing here is a recommendation to treat any medical condition, and nothing here replaces manufacturer training.

What each component does
Cross-linked hyaluronic acid, 20 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. Sosum is listed at 20 mg/mL, and the three gels differ in firmness and injection depth.
LTSR
LTSR stands for Low Temperature Stabilization Reaction. It is JSBIO’s name for its low-temperature cross-linking process, which the manufacturer describes as giving a dense, finely dispersed gel. This is the manufacturer’s description, and we do not hold independent data on it.
Lidocaine
Distributor listings differ on whether each Sosum gel contains lidocaine. Check the ingredient list on the carton to confirm what your syringe contains. If it contains lidocaine, screen patients for lidocaine allergy.
Which gel for which area
- S: fine lines, injected into the upper dermis.
- M: nasolabial folds, lip lines and marionette lines, injected into the middle dermis.
- H: contouring and volume, injected into the deep dermis and subcutaneous layer.
Approved indications differ by market. Confirm them in the instructions for use for your country.
How it works
The gel is placed in the skin or deeper tissue, where it adds volume mechanically and binds water. The cross-linking slows its breakdown, and the body gradually absorbs it over months.
How Sosum 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 if the syringe contains it), 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 S, M or H 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
S is injected into the upper dermis, M into the middle dermis and H into the deep dermis or 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.
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. Do not reuse or resterilise. 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 to lidocaine if the syringe contains it.
- 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
Storing and handling Sosum
Follow the storage temperature on the carton and in the instructions for use. Do not freeze, and protect from direct sunlight.

Use immediately upon opening. Single patient, single session. Do not reuse or resterilise. Discard the syringe and needle after use.
