Description
Sofiderm Derm Sub‑Skin is a cross‑linked hyaluronic acid gel filler supplied in a 20 ml syringe (no needle included), intended for deep dermis or subcutaneous injection. It is marketed for body shaping, buttock or breast enhancement, filling large soft‑tissue defects, correction of lipoatrophy, and deep volumising applications including subcutaneous facial augmentation. :contentReference[oaicite:0]{index=0}
Bnefits
- High HA concentration (around 20 mg/ml) with large particle size allows effective volumetric augmentation. :contentReference[oaicite:1]{index=1}
- Suitable for deep or sub‑cutaneous injections — useful for large‑volume body contouring (buttocks/hips/breasts) as well as facial volumisation in deeper tissue planes. :contentReference[oaicite:2]{index=2}
- Cross‑linked HA gel uses BDDE technology — aimed at ensuring stability and longer durability. :contentReference[oaicite:3]{index=3}
- CE/ISO certifications (per manufacturer info) provided. :contentReference[oaicite:4]{index=4}
Indications
- Body shaping / contouring — buttock, hip, breast enhancement or augmentation. :contentReference[oaicite:5]{index=5}
- Correction of soft tissue volume loss — facial lipoatrophy, facial asymmetry, HIV‑associated lipoatrophy, large tissue defects. :contentReference[oaicite:6]{index=6}
- Deep volumetric facial augmentation — zygomatic projection, chin/jawline enhancement, mid‑face restoration under subcutaneous plane. (per filler‑use protocols) :contentReference[oaicite:7]{index=7}
- Filling and augmentation where deep tissue support and volume restoration is required — not only superficial wrinkles but structural volume loss. :contentReference[oaicite:8]{index=8}
Composition
- Cross‑linked hyaluronic acid (HA), approx. 20 mg/ml (20 ± 3 mg/ml according to manufacturer) :contentReference[oaicite:9]{index=9}
- Gel matrix formed using BDDE cross-linker (common in Sofiderm fillers) to stabilise HA network. :contentReference[oaicite:10]{index=10}
Packaging
- Single 20 ml pre-filled syringe (no needle included). :contentReference[oaicite:12]{index=12}
Usage
- For injection by qualified and trained medical professionals only. :contentReference[oaicite:13]{index=13}
- Inject into deep dermis or subcutaneous tissue — technique (bolus, supraperiosteal, subcutaneous) depending on indication (body contouring, facial volume, soft‑tissue deficits). :contentReference[oaicite:14]{index=14}
- Use appropriate needle or cannula as per practitioner’s standard operating protocol; note that syringe is supplied without needle. :contentReference[oaicite:15]{index=15}
- Follow standard aseptic technique, aftercare protocols and patient‑specific guidelines post‑injection.
Contraindications
- Known hypersensitivity to hyaluronic acid or formulation components (e.g. BDDE residues). (standard filler contraindications)
- Active skin infection or inflammation at injection site — avoid until resolved.
- Use only by qualified aesthetic medicine professionals — not for unqualified/self‑administration.
Adverse Effects
- Temporarily possible swelling, bruising, redness, tenderness at injection or filler site — common post‑injection effects.
- Risk of lumps, over‑correction or asymmetry if not injected properly — especially given deep plane and large volume use.
- Rare but serious risks with deep filler injections: vascular occlusion, tissue necrosis, infection — particularly if injected incorrectly or by untrained personnel (general to HA fillers).
Storage Conditions
- Store as per manufacturer guidelines (often at 2–25 °C, away from direct sunlight) until use. :contentReference[oaicite:17]{index=17}
- Use before expiry date on syringe; discard if packaging integrity compromised.
Duration
Not therapeutic \u2014 aesthetic effect duration reportedly between 6\u201324 months depending on injection site, volume, and patient factors. :contentReference[oaicite:16]{index=16}
Onset
Immediate volumetric augmentation / contour change upon injection; final settling over days as swelling subsides (common to HA fillers).
