Inclusion Criteria:
1. Review and sign the Independent Ethics Committee (IEC)-approved Informed Consent Form
(ICF) prior to any study-related procedures being performed. In addition, the subject
will be asked to provide a separate release for use of their photographs in
publications and the clinical investigation report (CIR). The subject has a right to
refuse the photo release without jeopardizing their eligibility to participate in the
study.
2. Male and female subjects aged 18 to 65 years (inclusive) at the time of screening.
3. Subject desires correction of NLFs.
4. Moderate to severe bilateral aging defects in the nasolabial area, with wrinkles
classified as grade 3 or 4 according to the NLF WSRS on each side as assessed by the
blinded evaluator. NLFs should be of the same grade on the left and right side of the
face (i.e. approximate bilateral symmetry).
5. Subject, that in the opinion of the blinded evaluator, can improve at least 1 step on
the investigator-rated NLF WSRS with a maximum volume of 2.0 mL/NLF for initial
treatment and 1.0 mL/NLF for touch-up.
6. Female of child-bearing potential (sexually active and not sterile nor postmenopausal
for at least 1 year) should have a urine pregnancy test evaluated as negative on the
day of enrolment, and agree to use a reliable method of contraception for the duration
of the study (effective birth control measures include sexual abstinence, combined
[estrogen and progestogen containing] hormonal contraception associated with
inhibition of ovulation [oral, intravaginal, transdermal], progestogen-only hormonal
contraception associated with inhibition of ovulation [oral, injectable, implantable],
intrauterine device [IUD] or intrauterine hormone-releasing system [IUS] and/or condom
with spermicide).
7. Subject agrees to abstain from any facial cosmetic or surgical procedures during the
study period.
8. Subject agrees to refrain from excessive weight gain or loss (±10%) during the
investigation period.
9. Subject has adequate understanding of the local language to understand verbal and
written subject information and is willing to comply with the study requirements.
Exclusion Criteria:
1. History of any clinically significant disease or disorder, including porphyria or
systemic disorders affecting wound healing, which, in the opinion of the investigator,
may either put the subject at risk because of participation in the study, or influence
the results or the subject's ability to participate in the study.
2. Any clinically significant illness, medical/surgical procedure or trauma within 4
weeks of the first administration of investigational device and comparator.
3. History of anaphylaxis, multiple severe allergies, atopy, or allergy to sodium
hyaluronate products or to streptococcal proteins or have plans to undergo
desensitization therapy during the term of the study.
4. History of immune system disorders (e.g., autoimmune disease, human immunodeficiency
virus [HIV]-positive status, history of immune system degradation, or recurrent herpes
simplex).
5. History of streptococcal disease (e.g. recurrent sore throat) and subjects with
rheumatic fever, as judged by the investigator.
6. Dermatological problems (e.g. cutaneous lesions, inflammatory skin conditions,
hypertrophic scars or a tendency for keloid formation) at the discretion of the
investigator.
7. Noticeable scarring (including acne scarring), prior surgery, an active inflammation,
infection, cancerous or pre-cancerous lesion, history of prior significant trauma to
the midface, such as dog bite or laceration, resulting in formation of a scar, or
unhealed wound or have undergone radiation treatment in the area to be treated.
8. Cheek tattoos, piercings, facial hair, or scars that would interfere with
visualization of the cheek area for the effectiveness assessments.
9. Very thin skin in the mid-facial region, tendency to accumulate fluid in the lower
eyelids, or large infraorbital fat pads, i.e., significant convexity or projection
from the infraorbital fat pads.
10. Mid-face volume deficit due to congenital defect, trauma, abnormalities in adipose
tissue related to immune-mediated diseases such as generalized lipodystrophy (e.g.,
juvenile dermatomyositis), partial lipodystrophy (e.g., Barraquer-Simons syndrome),
inherited disease or HIV-related disease.
11. Moderate or severe abnormal midface or cheek asymmetry.
12. Ongoing or history of use of immunosuppressive therapy.
13. Use of anti-coagulation, anti-platelet, or thrombolytic medications, anti-inflammatory
drugs, or other substances known to increase coagulation time (as detailed in Section
9.6.2) within 10 days prior to treatment with the investigational device and
comparator.
14. Use of any new (i.e. that the subject has not used before) facial over-the-counter or
prescription, oral or topical, anti-wrinkle products within 90 days prior to enrolment
or planning to begin use of such products at any time during the study.
NOTE: Continued therapy with some cosmeceuticals (e.g., alpha hydroxyl acids, glycolic
acids, retinol, or retinoic acids) is allowed if the regimen was established = 90 days
prior to enrolment. The use of sunscreens is also allowed.
15. Known sensitivity to any investigational device or comparator components (see Section
10.1).
16. Previous cosmetic or aesthetic procedures as follows:
i) All types of previous surgical surgery below the lower orbital rim ii) All types of
permanent fillers below the lower orbital rim iii) Previous semi-permanent fillers
below the orbital less than 2 years before treatment iv) Previous treatment with
HA-based fillers less the 18 months prior to enrolment v) Treatment with
photochemotherapy or lasers less than 6 months before enrolment vi) Mechanical,
chemical or medical peeling less than 6 months prior to enrolment vii) Treatment with
botulinum toxins less than 12 months prior to enrollment viii) Major dental procedures
less than 6 months prior to enrolment
17. The presence of abnormal midface function, with inability to effectively puff cheeks,
smile broadly, or chew.
18. Pregnant, lactating, or planning to become pregnant at any time during the study.
19. Positive screen for drugs of abuse or alcohol at screening or on admission to the unit
prior to administration of the investigational device and comparator.
20. History of alcohol or drug abuse or excessive intake of alcohol, as judged by the
investigator.
21. Has received any investigational device within 30 days prior to study enrolment or is
planning to participate in another investigation during the course of this study.
22. No access to an electronic device (e.g. smartphone, tablet or personal computer) on

(CRO) responsible for conducting the study, sponsor, or a sponsor representative.
24. The Investigator considers the subject unlikely to comply with study procedures,
restrictions and requirements.
