Description

• Sosum — LTSR Hyaluronic Acid Filler Series

  Sosum is a hyaluronic acid (HA) dermal filler series from JSBIO Co., Ltd. in South Korea. The brand name comes from the Korean word “솟음,” derived from “솟아오르다,” meaning “to rise up” — reflecting the line’s focus on lifting skin and reducing wrinkles.

  Sosum uses JSBIO’s Low Temperature Stabilization Reaction (LTSR) technology, a cross-linking process carried out at low temperatures. This produces a dense, finely-packed HA gel structure. The series carries this structure across three variants tailored to different correction depths.

  At a Glance

  Technology	Low Temperature Stabilization Reaction (LTSR)
  Residual BDDE	Near-zero, via two-step purification
  Duration	Up to 12 months
  Shelf Life	24 months from manufacturing date
  Manufacturer	JSBIO Co., Ltd., South Korea

  Main Benefits

  • Dense, finely-packed gel structure: low-temperature cross-linking supports high viscosity and elasticity
  • Near-zero residual BDDE: two-step purification helps minimize allergic reactions and side effects
  • Low injection force: supports smoother, more even distribution with less discomfort
  • Long-lasting results: high cross-linking resists degradation, supporting effects up to 12 months

  Choosing the Right Variant

  Variant	Best For	Injection Depth
  Sosum S (Soft)	Fine lines, superficial wrinkles, early signs of aging	Upper (superficial) dermis
  Sosum M	Moderate wrinkles and folds — nasolabial folds, forehead lines, frown lines, lip lines, marionette lines	Middle dermis
  Sosum H	Deep facial lines and folds, face contouring and volumizing	Deep dermis and subcutaneous tissue

  What’s Inside

  Active Ingredient	Cross-linked Hyaluronic Acid — 20mg/mL

  How Sosum Works

  Because JSBIO carries out the cross-linking reaction at low temperatures, the resulting HA gel forms a denser, more finely-packed structure than gels processed at standard temperatures. This structure directly supports the filler’s elasticity, viscosity, and resistance to breakdown.

  After cross-linking, Sosum goes through a two-step purification process to remove residual BDDE, the cross-linking agent itself. Combined with low endotoxin levels, this helps reduce the risk of allergic reactions or post-injection irritation. Because the gel structure is finely divided, it also requires less force to inject. This supports more even distribution and a lower risk of bruising or swelling.

  Frequently Asked Questions

  What is Sosum?
  Sosum is a hyaluronic acid dermal filler series from JSBIO, built on Low Temperature Stabilization Reaction (LTSR) technology and available in three variants for different correction depths.

  How do I choose between Sosum S, M, and H?
  Sosum S suits fine lines and superficial wrinkles. Sosum M suits moderate wrinkles and folds like nasolabial lines. Sosum H suits deep structural volumizing and facial contouring.

  Why does Sosum use low-temperature cross-linking?
  Processing the gel at low temperatures produces a denser, more finely-packed HA structure, which supports better elasticity and longer-lasting results.

  How long do results last?
  Results generally last up to 12 months, depending on the variant and treatment area.

  Does Sosum cause discomfort during injection?
  Because the gel’s finely-divided structure requires less injection force, most patients experience a smoother, more comfortable procedure with lower risk of post-treatment bruising.
