The Technology

Precision built for what fillers can’t reach.

GentleFill is an investigational medical device, currently in development, engineered to deliver dermal fillers at depth ranges that have historically sat between two clinical tools: too shallow for conventional fillers, and unaffected by Botulinum toxin.

The clinical gap

Etched dermal lines — the fine, static creases that remain after neuromodulator treatment — are notoriously difficult to address. Botulinum toxin relaxes the underlying muscle but cannot fill the lost volume in the upper dermal layers. Conventional dermal fillers are formulated for placement at depths and volumes that, when applied to these shallow lines, often produce uneven results, palpable beading, or surface irregularities.

How GentleFill is designed to work

The device combines a depth-controlled delivery mechanism with sub-microliter dose metering and articulated needle positioning, engineered to enable consistent placement at the superficial dermal depths where etched lines reside.

Specifications

Intended clinical applications

The device is being developed with a primary focus on the controlled delivery of dermal fillers for the correction of etched dermal lines.
