Diabetes Technology — Skin Care

Skincare for Type 1 Diabetes and Technology

Your skin is a biological interface under repeated load from adhesives, sensors, cannulas, and constant rotation. When skin fails, devices fail. Good skin care keeps both working.

The core principle: load management

Skin problems in people using CGM and insulin pumps almost always come from a mismatch between load and recovery. Devices increase load on the skin through adhesive contact, occlusion, sweat trapping, friction, and repeated micro-trauma from insertions.

Managing skin is not about achieving perfect skin. It is about managing that load: choosing better sites, rotating intelligently, preparing the skin properly before application, removing gently, and building recovery time into the rotation cycle.

Easy wins — start here

Pick flatter sites, avoid rub zones, rotate properly
Prep means clean plus fully dry — most adhesion issues are moisture and friction issues
Use barriers only when needed — too much coverage can create new problems
Remove low and slow with oil or adhesive remover to avoid skin tears
Recover on purpose: moisturise and rest sites; avoid re-using a site just because it looks acceptable

Common skin problems — what tends to happen

Irritation or rash — often adhesive allergy or irritant contact dermatitis, sweat trapping, or repeated low-grade trauma from movement.
Dry or itchy skin and eczema — commonly occurs when the skin barrier does not recover adequately between wears.
Lipohypertrophy and lipoatrophy — tissue changes from repeated insulin delivery and overuse of the same zones. Lipohypertrophy causes hardened fatty deposits; lipoatrophy causes hollowing.
Scars, wounds, and skin tears — most often caused by rapid removal technique rather than slow, oil-assisted removal.
Infection — warm, red, painful, spreading, or discharging areas need prompt review.

Most of these problems are preventable with consistent attention to the five areas below.

1. Site choice — avoid lumps, bumps, and bendy areas

Site placement determines a significant proportion of skin outcomes. Sites too close to joints, waistbands, scars, or high-friction areas manufacture irritation. Sites used too repeatedly cause tissue breakdown and, for pump users, increase lipohypertrophy risk.

Prefer flat, fatty zones: upper arms, buttocks, thighs, and flanks.
Avoid areas that bend or rub, such as waistbands and bony creases.
Rotate deliberately: use 6–10 zones and give each at least a week of rest.
Keep at least 1–2 inches away from previous sites or current insulin delivery areas.

2. Soap–Water–Dry — prepare the skin consistently

Preparation does not need to take long. It needs to be consistent.

Clean with oil-free soap and water. Avoid alcohol-based prep wipes if you react to them.
Dry thoroughly. Damp skin and steamy bathrooms are the two most common causes of adhesion failure.
For people who sweat heavily: apply a thin layer of solid, unscented antiperspirant to the site, leave for around 10 minutes, then wipe off completely before applying the device.

For people prone to reactions, introduce one variable at a time and observe the effect:

Barrier wipes (for example Cavilon or Skin Tac) to protect the skin surface under the adhesive.
Barrier films placed under the device (for example IV3000 or Tegaderm) for sensitive skin.
Fluticasone spray is sometimes used off-label as a clinician-guided strategy: applied to the area and allowed to dry completely before device application.

3. Extra tape — use when needed, not by default

Where possible, avoid extra tape to limit total skin coverage under occlusion. But sometimes the device adhesive does not hold well enough, and sometimes it holds too well.

Over-patches can help when adhesion is poor (for example RockaDex, GrifGrips, Simpatch).
When using additional tape, picture-frame around the edges rather than full coverage where possible.
Elastic wraps (for example Coban) or kinesiology tape can be useful for sport and high-sweat situations.

4. Low and slow — remove without damage

Most skin tears occur from pulling the sensor or patch upward and away from the skin, rather than folding it back on itself slowly.

Use baby oil, olive oil, or dedicated adhesive removers (for example Lift Plus, PIP code 3188505; Uni-Solve; TacAway) to loosen the adhesive before removal.
Start at a corner. Push the skin down gently with one hand and slowly fold the tape back over itself — not up and away.
Once removed, clean the site and apply a moisturiser.

5. Rotate for restoration

Whether the skin feels fine or slightly irritated after removing a device, what happens next matters.

Use a rich, unscented moisturiser daily, especially on sites currently resting.
Leave used sites alone for at least a week before reusing them.
Watch for infection signs: heat, pus, spreading redness, or escalating pain. Escalate to a clinician earlier rather than later if these appear.

When things go wrong — a quick reference

Despite good preparation, skin problems still sometimes occur. The table below covers first steps and when to seek further guidance.

Skin issue	First steps	Then consider
Redness or rash	Clean, moisturise, use barrier wipes	Clinician-guided anti-inflammatory strategy (for example fluticasone or mild topical steroid)
Eczema	Barrier film under device (for example IV3000 or Duoderm)	Short course topical steroid — clinician-guided
Persistent itching	Moisturise and add barrier film	Topical steroid or antihistamine — clinician-guided
Lipohypertrophy	Rotate sites more effectively and rest the affected zone	Avoid the zone for at least several weeks; refer if severe or affecting insulin absorption
Wound or skin tear	Use oil-assisted removal from now on; rest the site; moisturise and protect	GP review if not healing or if infection is suspected

Practical summary

Pick low-rub sites and rotate across 6–10 zones
Soap–Water–Dry: fully dry the skin before application — no steam, no damp
Add barriers only when needed, changing one variable at a time
Remove low and slow using oil or adhesive remover
Rotate to recover: moisturise resting sites and give each zone at least a week off
