  "what": "Juvelook is a collagen-stimulating injectable made by VAIM in Korea that combines poly-D,L-lactic acid (PDLLA) microspheres with non-cross-linked hyaluronic acid, sitting between a skin booster and a volumising filler. Dr Sin Yong offers it on Orchard Road, Singapore, for skin quality and fine texture after assessing skin quality, volume and previous injectables, though he prefers energy-based treatment for almost every concern. It does not lift sagging skin, and hyaluronidase dissolves its hyaluronic acid but not the PDLLA.",
  "key_facts": [
    "Composition: a 50 mg vial contains 42.5 mg PDLLA and 7.5 mg hyaluronic acid; Juvelook Volume (Lenisna) 200 mg contains 170 mg PDLLA and 30 mg hyaluronic acid, according to the manufacturer",
    "Versus Sculptra: Juvelook uses amorphous, spherical, partly porous PDLLA microspheres of about 30 µm in hyaluronic acid; Sculptra uses semi-crystalline, sheet-like PLLA flakes of about 50 µm in carboxymethylcellulose; the two have not been compared head to head in people",
    "Uses: Juvelook for skin quality, fine lines and texture; Juvelook Volume for deeper volume and structure; sagging is a lifting problem it does not answer",
    "Preferred alternatives: FSX Laser for the skin and the Restore arm of the VF Lift – Vertical Facelift for hollow areas, including under the eyes, because they add no injected material",
    "Should wait or not have: pregnancy or breastfeeding, infection or inflammation in the area, allergy to a component, a keloid tendency, earlier filler of unknown type (assessed with ultrasound first), or a wish for a fully reversible result",
    "Evidence: small case series and case reports, much of it from one research group; no randomised trial against Sculptra or hyaluronic acid filler has been published, and no duration is promised",
    "Risks: swelling, bruising and tenderness are expected; nodules can occur with any collagen stimulator; vascular occlusion is the serious risk, and vision change or eye pain after an injection is an emergency",
    "Excess or lumpy Juvelook: mapped with ultrasound, an inflamed lump treated medically first, and nodules treated with the Sculpting mode of Time Freeze Laser LCLR®, without an incision; Dr Sin Yong also manages Juvelook placed elsewhere"
