DUALTHERA PLAGALVA Dual Effect

1 December 2025

USD 700 (RRP): one cordless, USB-C rechargeable handpiece. No cartridges, gel pads or filters, ever. Single-energy professional plasma devices sell for USD 900-1,700, and none combines two energies. DUALTHERA puts plasma and galvanic energy in one handpiece for less, replacing two machines. Consumers already spend heavily on anti-aging serums, yet up to 99% of actives never pass the skin barrier. DUALTHERA turns that spending into results: the first purchase is the only purchase, and every ampoule on the shelf starts working harder.

Using its patented PLAGALVA technology, DUALTHERA targets skin cells’ energy while driving skin care actives deeper into the skin. The PLAGALVA technology uses cold plasma to energize skin cells, raising cellular ATP and activating fibroblasts, while galvanic microcurrent drives actives through temporary micro-channels. The plasma offers cell-level renewal, as dielectric barrier discharge creates cold atmospheric plasma and reactive oxygen and nitrogen species. This opens temporary, reversible micro-channels in the stratum corneum, and also helps purify the skin’s surface. And galvanic provides active delivery, as a controlled DC microcurrent of 10-500 µA pushes ionized actives into the skin. The PLAGALVA technology allows these two elements to work in synergy, so together the plasma and galvanic raise cellular ATP production, activating fibroblasts and shortening the skin-cell renewal cycle. In tests, nasolabial folds reduced by up to 70.99% in four weeks; skin density improved up to 40.55%; and cheek sagging reduced by 21.17%.

The only home device that targets the skin cell itself. Heat-based devices push ageing cells to make collagen faster. DUALTHERA's patented PLAGALVA technology (KR 10-2531623) renews instead: cold plasma energises the cells, raising cellular ATP and activating fibroblasts, while galvanic microcurrent drives actives through temporary micro-channels, in the same pass. A proprietary IGBT circuit runs two incompatible energies together in one cordless handpiece. The proof glows: a soft violet plasma light on the skin, nasolabial folds up to -70.99%, and absorption depth up to 7.37x.

Two independent human application studies by the Korea Institute of Dermatological Sciences (KIDS), Seoul, under KIDS SOP with quality-assurance review. All key results p<.001. Study 1: absorption, KIDS-BCD026-RWR - 22 women aged 43-59 (mean 52.6); the same ampoule on both forearms, DUALTHERA on one side, hand application on the other; 3D Raman spectroscopy - Absorption amount: 2.39x on average, up to 5.42x - Absorption speed: 2.59x on average, up to 7.37x - Absorption depth: 2.59x on average, up to 7.37x - Before the study, 100% said skincare never absorbed quickly into their skin; after one session, 100% said it did - 100% satisfied with DUALTHERA's convenience, care, efficacy and overall experience Study 2: four-week anti-aging regimen, KIDS-BCD025-RWR - 21 women aged 41-65 (mean 53.1); DUALTHERA for 3 minutes per ampoule with LYLYL ampoules - Instruments: Cutometer, ANTERA 3D, DUB skin scanner, F-RAY, Epsilon E100, MoistureMeterD, VISIA-CR - 100% of participants satisfied with DUALTHERA and both ampoules Top 3 results (four-week average / best result) - Nasolabial fold depth: -36.80% / -70.99%, 4.3x the 16.3% reported for a best-selling Korean home device - Skin density: +15.17% / +40.55%, 4.8x the 8.5% reported for the same device - Surface hydration: +93.09% after a single session, up to +283.5%, 27x the 10.5% reported for a leading booster device More results (average / best) - Elasticity: +5.60% / +10.76% - Cheek sagging angle: -6.59% / -21.17% - Texture roughness: -11.21% / -22.75% - Inner hydration: +8.72% / +19.36% - Radiance: +1.27% / +9.53% One night is enough to notice - After the very first session: nasolabial folds -16.34%, skin density +11.74% What this means - Heat-based devices ask ageing cells to work harder; DUALTHERA renews them, so results are strongest where skin needs them most - The study group averaged 53 years old, and change began with the first session and built over four weeks Safety - Zero adverse skin reactions in 43 participants - KIDS conclusion: improvement confirmed in absorption and in all eight skin-quality parameters Comparative references - 4.3x, 4.8x and 27x compare DUALTHERA's maximum results with separately published device results; protocols differ. - The four-week regimen combined DUALTHERA, Vita ABCDE and Calming Recovery Ampoules.

Renews, not just stimulates - Plasma targets the skin cells themselves: cellular ATP rises, fibroblasts activate, renewal speeds up - Most dramatic on mature skin: many users see the difference the morning after one session Visible results - Nasolabial folds up to -70.99% (average -36.80% in four weeks) - Skin density up to +40.55% - Cheek sagging angle up to -21.17%: a lifted contour - Texture roughness up to -22.75% Hydration and glow - Surface hydration up to +283.5% after a single session - Surface hydration +93.09% on average after one session - Inner hydration up to +19.36%; radiance up to +9.53% Skincare that finally gets in - Absorption up to 5.42x; speed and depth up to 7.37x - Every serum already on the shelf works harder - Before: 100% said skincare never absorbed quickly. After one session: 100% said it did Safe and effortless - Cold plasma also helps purify the skin surface - Pain-free, needle-free, no downtime, with dual high-voltage and microcurrent output - A full-face treatment in about three minutes; cordless, light, one-handed - Zero adverse reactions in 43 clinical participants
