  "what": "Deusaderm is an injectable cross-linked porcine collagen gel with lidocaine, made by Sunmax Biotechnology in Taiwan, that places collagen in the skin rather than stimulating the skin to make its own. At Dr Sin Yong's practice on Orchard Road, Singapore, he reserves it for thin-skinned areas such as the tear trough and fine periorbital or perioral lines, placed superficially in small amounts. It does not draw in water, is not a volumiser, and cannot be dissolved with hyaluronidase.",
  "key_facts": [
    "Composition: highly purified, cross-linked porcine skin collagen, predominantly type I with a type III fraction; Sunmax specifies 35 mg/mL collagen and 3 mg/mL lidocaine hydrochloride",
    "Category: collagen placed, not collagen stimulated; Sculptra, Ellansé and Radiesse place a scaffold the skin builds collagen around, and hyaluronic acid fills and binds water",
    "Why under the eye: collagen is non-hydrophilic and opaque, so it does not swell afterwards or produce the bluish Tyndall tint that hyaluronic acid can show under thin lower-eyelid skin",
    "Reversibility: none; hyaluronidase acts on hyaluronic acid and nothing else, and collagen is resorbed by the body over months, so no duration is promised",
    "Assessment: Dr Sin Yong first separates a true tear-trough hollow, a bulging fat pad and thin or pigmented skin; collagen addresses thin skin, not the other two, and a face with earlier injections is scanned with ultrasound before anything is added",
    "Does not suit: a bulging fat pad (referred for surgical assessment), a deep hollow needing structure, pigment-driven dark circles, a goal of volume, or allergy to collagen, pork-derived products or lidocaine",
    "Evidence: the main published trial (252 participants, 2024) studied nasolabial folds, not the under-eye; periorbital use rests on how collagen behaves; injection-site redness, swelling, bruising and itch are common, nodules are reported, and vascular risk is heightened near the eye",
    "Performed by: Dr Sin Yong personally, who assesses the cause of a tired lower eyelid before anything is placed"
