Plain English Summary
Background and study aims
The skin loses its structure and functionality as we age. This is caused by different factors like metabolic aging and oxidative stress caused by UV light and pollution. A night serum contains antioxidants and ingredient that improves skin's elasticity and firmness. The aim of this study is to evaluate the anti-aging effect of the night serum in the improvement of the clinical signs of skin/facial aging.
Who can participate?
Healthy volunteers (men and women), aged between 40 and 75 years old with moderate skin aging
What does the study involve?
Participants use the serum every night for 12 or 24 weeks (depends on the site) on the face, neck and neckline. Doctors evaluate their skin before and after (at 6, 12, 18 and 24 weeks) the use of the product and take photographs of the face. Participants are also asked to evaluate their skin condition and quality of life at the same timepoints. Participants in the biopsy study have biopsies (samples) taken from the forearm (at site 1) or from the neck (at site 2).
What are the possible benefits and risks of participating?
The potential benefit of participating is an improvement in the appearance of the face, neck and neckline. The potential risk is discomfort on the skin. For participants having biopsies potential risks are the ones related to this kind of procedure.
Where is the study run from?
1. Skin Laser & Surgery Specialists, Hackensack, NJ (USA)
2. Modern Dermatology, Westport, CT (USA)
When is the study starting and how long is it expected to run for?
June 2018 to July 2019

Skin with moderate signs of aging
Subjects were instructed to use the serum once a day at night on the face, neck and neckline for 12 weeks. On site n#2 subjects participated in an extension period to 24 weeks.
Efficacy assessments were conducted on week 6, 12, 18 and 24 (standardized photos, expert investigator grading, subjects reported outcome measures).
Skin biopsies were collected from the arms (treated and untreated arm) at baseline and Week 12 at site#1 and the neck (baseline and treated sun-exposed area) at baseline and Week 24 at site#2.
Primary outcome measure
Signs of aging considering separately each sign graded by the investigators scale (radiance, skin texture/smoothness, pigmentation, erythema, pore size, skin tone, skin complexion, lines, wrinkles and youthful appearance) at baseline, Week 6, Week 12, Week 18 and Week 24
Secondary outcome measures
1. Change in overall fine lines, wrinkles, hyperpigmentation and erythema measured using Investigator Global Aesthetic Improvement Scale (GAIS) evaluated by investigator at baseline, Week 6, Week 12, Week 18 and Week 24
2. Change in radiance, skin texture/smoothness, pigmentation, erythema, pore size, skin tone, skin complexion, lines, wrinkles and youthful appearance measured using Skin Quality Assessments scale evaluated by investigator at baseline, Week 6, Week 12, Week 18 and Week 24
3. Photodamage and hyperpigmentation measured using the Investigator Global Assessment (IGA) scale evaluated by investigator at baseline, Week 6, Week 12, Week 18 and Week 24
4. Change in signs of facial aging measured using Wrinkle Severity Scale evaluated by investigator at baseline, Week 6, Week 12, Week 18 and Week 24
5. Change in overall fine lines, wrinkles, hyperpigmentation and erythema measured using Subject Global Aesthetic Improvement Scale (SGAIS) evaluated by subject at baseline, Week 6, Week 12, Week 18 and Week 24
6. Change in lines/wrinkles, spots, redness, firmness, radiance/luminosity and skin texture/smoothness measured using Standardized digital images captured with VISIA or standardized system evaluated at baseline, Week 6, Week 12, Week 18 and Week 24
7. Local (dermal) tolerability examination on investigational areas including assessments of stinging/burning (rated by the subject), dryness, scaling, edema and erythema (rated by the investigator). It will be evaluated by grading from 0 (None) to 3 (Severe) at all study visits
8. Adverse events, including the seriousness, grade and causal relationship with IP as per adverse event standard criteria, recorded in the CRF on Week 6, Week 12, Week 18 and Week 24
