Case study
Facial Skincare Device Design
A wellness brand needed a handheld facial skincare device that could feel comfortable and premium in hand while keeping the internal electronics sealed against bathroom moisture.

Project fit
Why this case may be relevant to your product
Each theme maps to a common product-development decision: whether to fund engineering files, prototype, tooling, supplier sampling or pilot approval.
Project concern
Wellness brands need a personal device that feels premium in hand without compromising the water seal around daily bathroom use.
Best-fit need
personal care device design, wellness device enclosure design, bathroom-use product CMF direction.
What we helped reduce
Moisture ingress at the seam line, an uncomfortable working angle and a charge port that fights the seal.
Review angle
Review a personal care device housing before prototype or tooling.
Case story
Challenge, approach and result
Use this section to understand what changed through the project before comparing visuals.
| Project stage | What happened | Why it matters |
|---|---|---|
| Challenge | The team had a validated PCB, battery and vibration-motor platform, but no housing direction that balanced grip comfort, seal integrity and a premium retail appearance. | Clarifies why the team could not simply approve the next spend. |
| Main concern | A housing built only around the electronics footprint could create seam lines that trap moisture, an uncomfortable grip angle or a charging interface that compromises the water seal. | Shows the commercial or technical issue behind the project. |
| Approach | Align grip geometry, seal-line placement, charging interface and button feel before committing to tooling. | Explains how form, structure, prototype route and supplier questions were connected. |
| Work completed | Housing architecture map for roller head, motor, battery and charging port placement. Exploded view separating the outer shell, gasket seal and internal motor module. | Makes the case more useful than a finished image alone. |
| Result | Clarified a premium, sealable housing direction before committing to tooling. Reduced the risk of seam-line moisture ingress or an uncomfortable grip angle. | Helps similar teams judge whether the same path fits their product stage. |

Project materials behind the result
A useful example should show more than a finished image: inputs, structure, prototype notes and production preparation all matter.

Project snapshot
What had to be solved
A useful case explains the project situation, not only the final visual.
Starting point
The team had a validated PCB, battery and vibration-motor platform, but no housing direction that balanced grip comfort, seal integrity and a premium retail appearance.
Main risk
A housing built only around the electronics footprint could create seam lines that trap moisture, an uncomfortable grip angle or a charging interface that compromises the water seal.
Design response
Align grip geometry, seal-line placement, charging interface and button feel before committing to tooling.
Work map
How the work connects to the next step
Case pages separate inputs, completed work and approval gate so your team can judge whether a similar engagement fits your stage.
Inputs received
Product goal, current files, target user, constraints, references and supplier or prototype context when available.
Work completed
Form, structure, 3D files, prototype, DFM or supplier-review outputs tied to the decision being made.
Next step
A practical next decision: fund engineering files, build prototype, revise before tooling, ask supplier questions or approve pilot conditions.
Deliverables
What your team should be able to review
A strong industrial design case includes visual and technical outputs across form, structure, prototype and manufacturing preparation.
- Shown: Housing architecture map for roller head, motor, battery and charging port placement.
- Shown: Exploded view separating the outer shell, gasket seal and internal motor module.
- Shown: CMF direction across white, blush and champagne finishes with matching roller plating.

Result notes
What changed through the project
These client-safe outputs show the kind of project progress you should expect.
- Result: Clarified a premium, sealable housing direction before committing to tooling.
- Result: Reduced the risk of seam-line moisture ingress or an uncomfortable grip angle.
- Result: Produced three CMF routes aimed at bathroom-shelf and gift-set retail presentation.
- Result: Fixing seal-line placement before tooling typically lets the housing hit its splash-resistance target without adding a second gasket after the first sample.
Repeatable checklist
What a similar team should prepare
The first review gets faster when you can share the few details that define your current stage.
- Prepare: Existing PCB, battery and motor outlines.
- Prepare: Target water-resistance rating and charging method.
- Prepare: Reference products and target retail shelf.
- Prepare: Prototype goal: appearance model, functional sample or production-intent sample.
