Eligibility Criteria
You may qualify if:
- Aged 18 to 65 years old (inclusive), male or female;
- Subjects who are willing to receive temple filling treatment;
- Subjects with flat to severe temple hollowing on both sides (i.e. ATHS scores of 1- 4 on two sides, which are not necessarily the same but should have a difference of at most 2) as assessed by the blinded investigators;
- Subjects able to self-assess efficacy without spectacles or with contact lenses;
- Subjects who voluntarily sign the ICF, understand and accept the duration of the study, and will be able and willing to comply with all requirements, including scheduled treatment, follow-up, and other study procedures
You may not qualify if:
- With known allergic reactions to polycaprolactone (PCL),carboxymethylcellulose (CMC), glycerin or any ingredient in the product;
- With known history of severe allergic reactions and multiple severe allergies;
- With abnormal coagulation mechanism (activated partial thromboplastin time (APTT) \> 1.5 times the upper limit of normal) at screening, or having received any thrombolytic agent, anticoagulant, or antiplatelet drug (e.g.,warfarin, aspirin) within 2 weeks prior to enrollment;
- With temple hollowing due to trauma, congenital malformation, or congenital or acquired lipodystrophy;
- With previous or current temporal arteritis;
- With temporomandibular disorders or other mandibular diseases;
- With recurrent temporal headaches, such as temporal tendonitis, and migraine;
- Having received injection of polymethyl methacrylate, silicone, expanded polytetrafluoroethylene, autologous fat, or any other fillers in the temple;
- Having received injection of calcium hydroxyapatite, poly-L-lactic acid, polycaprolactone, or any other fillers in the temple within 2 years before enrollment;
- Having received injection of crosslinked HA or any other unknown materials above the subnasale within 12 months before enrollment (except the injections in nasolabial folds and mid-face);
- Having received collagen injection above the subnasale within 6 months before enrollment (except the injections in nasolabial folds and mid-face);
- Having received injection of non-crosslinked sodium hyaluronate (including skin boosters), short wave therapy, ultrasound therapy, laser or chemical peeling, dermabrasion, or any other treatment within 3 months before enrollment;
- Having received face lifting (thread lift) above the subnasale within 12 months before enrollment;
- Having received radio frequency therapy or botulinum toxin injection above the subnasale within 6 months before enrollment, such as periorbital rhytidectomy, and treatment of masseteric hypertrophy (except the injections in nasolabial folds and mid-face) ;
- Having ever received surgery in the temples, which affects efficacy evaluation as judged by the investigator;
- +12 more criteria
