LOS ANGELES, Calif. — [July 17, 2026]
KNESKO, the award-winning luxury skincare brand known for combining advanced skincare science with wellness, today announced the results of an independent third-party clinical study validating the performance of its signature Gold Repair Collagen Face Mask.
The four-week independent clinical study evaluated 30 participants representing multiple skin types and tones using expert clinical grading together with validated instrumental measurements, including Corneometer® analysis for skin hydration and Elastimeter® analysis for skin elasticity.
The study demonstrated statistically significant improvements in multiple measures of skin appearance and performance, confirming both immediate cosmetic benefits following a single 15-minute application and continued cumulative improvements with regular use over four weeks.

“Luxury skincare should never require consumers to choose between indulgence and efficacy,” said Lejla Cas, Founder and President of KNESKO. “For more than fourteen years, we’ve developed products that unite clinical performance with elevated self-care rituals. This independent clinical study validates what our spa partners and estheticians have experienced for years—that our Gold Repair Collagen Face Mask delivers immediate visible results while helping improve overall skin appearance with continued use.”
By investing in independent third-party clinical testing, KNESKO reinforces its commitment to scientific validation, transparency and professional credibility. The study provides spa professionals, retail partners and consumers with independently substantiated efficacy data to support professional treatment recommendations and at-home skincare routines.
The Gold Repair Collection has also received multiple Reader’s Choice Awards from American Spa, Skin Inc., MedEsthetics, Dermascope, and Spa & Wellness MexiCaribe, recognizing its performance across face, eye, neck & décolleté, and hand treatments.
