Independent clinical study: ELITE X600 GREDECO
GREDECO – Independent laboratory specializing in dermatology and cosmetology, under the direction of a dermatologist
90-day clinical study, 21 volunteers aged 35-65, measurements at Day 0 / Day 30 / Day 90 — 3 sessions of 10 minutes per week
Equipment: Cutometer MP 580 (firmness/elasticity), Cortex 20MHz Ultrasound (dermal density), Glossymeter GL200 (radiance), VISIA CR5 (texture, pores, erythema, spots), Chromameter CR400 (tone uniformity), Vapometer (skin barrier), PRIMOS CR300 (wrinkle depth), Bazin Scale (nasolabial folds), GREDECO Scale (tired skin), self-assessment questionnaire, dermatological control throughout the study
Statistics: Student's t-test and Wilcoxon test on paired data, normality verified by Shapiro-Wilk test, significance threshold p < 0.05
(All results below are statistically significant)
Objective instrumental results at Day 90:
Firmness: -15% skin deformability (p<0.0001) — from Day 30: -11%
Elasticity: +23% (p<0.0001) — from Day 30: +21%
Skin radiance: +21% (p<0.0001) — from Day 30: +23%
Signs of skin fatigue: -24% (p<0.0001) — from Day 30: -14%
Skin texture: -14% (p<0.0001)
Skin barrier (PIE): -12% (p<0.01)
Self-assessment questionnaire - 21 volunteers at Day 90:
95% notice smoother skin
90% notice more even tone
91% notice more radiant skin
86% notice more supple skin
76% notice pore reduction
81% notice younger-looking skin
Dermatological tolerance: excellent - 0 adverse events throughout the period
Results may vary by individual.
