Protocol ( 07 ) · Current, light, heat

The skin is an electrical organ.

This issue examines what happens when you pass a calibrated microcurrent through living tissue, why 630 nanometres matters, and how heat changes what your serum can do. Every claim links to its study.

Read it like a spec sheet.

Mechanism, then benefit, then claim. If a row cannot cite its study, it does not ship.

See the studies
01EMS

Pulsed stimulation recruits facial muscle fibres the way resistance recruits skeletal muscle.

Supports tone along the jaw and cheek with consistent use.

02Microcurrent

Sub-sensory current in the microampere range, the same order as the body's own bioelectric signalling.

Supports firmness. Studied since 1982, cited on every claim.

03Thermal

Controlled warmth increases local circulation and softens the stratum corneum.

Visibly improves how actives absorb, per session.

04LED 630-660nm

Red wavelengths reach the dermis and act on mitochondrial cytochrome c oxidase.

Supports collagen density with daily exposure.

Three clinicians, on record.

Statements, not endorsements
Dr. Amara Osei
"The honest claim for home microcurrent is frequency. Daily, correctly dosed stimulation is something no monthly clinic visit can replicate."
Dr. Amara OseiClinical dermatology, Berlin
Dr. Elena Vasquez
"At 630 to 660 nanometres the literature is genuinely strong. The variable that decides outcomes is not the device. It is adherence."
Dr. Elena VasquezPhotobiomodulation researcher
Maren Holt
"I stopped selling single treatments. Tissue responds to sequence, not to events. Twelve minutes a day outperforms an hour a month."
