A temporary effect of decreasing skin temperature by -4.99 degrees through immediate cooling was confirmed (same test conditions).
backed by evidenceContains the Zinc-Pep™ complex, Ectoin, and Panthenol to comfortably soothe skin sensitized by external irritants and help maintain healthy skin condition.
plausible, not testedA product that cares for the oil-moisture balance by applying the Zinc-Pep™ complex combining zinc and peptides to the cream-skin technology in which cream is melted into skin, and helps with skin soothing, skin texture refinement, and fresh moisturization.
partly backedWhile regular cream skin focuses on deep moisturization and skin barrier care, gel cream skin focuses on oil-moisture balance, skin soothing, and skin texture refinement, so even moisture-deficient oily skin that worries about both oiliness and inner dryness can use it without burden.
partly backedStabilizes gel cream ingredients in toner with Micro Blending Technology, allowing faster, fresher absorption without stickiness (own report, sensoroid friction coefficient measurement, compared to gel cream).
partly backedCompared to no application, less oil increase appears after 12 hours, controlling skin oil without inner dryness for 12 hours.
partly backedAfter 4 weeks of use, temporary results were confirmed that visible pores improved by 36.05% in volume, 31.89% in area, 22.01% in density, 21.97% in count, and pore area elasticity improved by 17.47% (same test conditions).
partly backedWith a non-sticky, fresh water-type texture, it can be used without burden even on moisture-deficient oily skin and oily skin, and helps with soothing, skin oil control, skin texture refinement, and inner moisturization.
partly backedIn a human application test, strengthening of oil-moisture balance by 59.32% and reduction of sebum secretion by 45.34% were confirmed immediately after use (2024-11-27~2025-01-03, 33 multiracial adult women aged 19-49, (Global Medical Research Center Co., Ltd.)).
overstatedImmediately after use, in a satisfaction survey compared to our own toner, makeup adherence and pick-up and skin texture refinement were answered as 100%, and after 2 weeks of use, oil control continuation without dryness was reported as 100%, makeup longevity improvement as 96.9%, and a feeling of skin becoming clearer as 93.9% (product use satisfaction survey results).
overstatedMoisturizing power at the level of gel cream was confirmed even in the toner formulation (result of comparison of moisturizing power with gel cream 24 hours after product use).
