How it works

The patch creates a short, controlled heat reaction that reaches sweat glands under the skin. This reduces how much they work.

FDA-authorized use

The FDA authorized Brella through the De Novo process for excessive underarm sweating. A trained clinician gives the treatment. It may be repeated as the effect fades.

Treatment course

The patch stays on each underarm for about three to four minutes. A visit often takes less than 30 minutes with setup. The timing of repeat visits depends on how long results last.

What to expect after treatment

Redness, warmth, tenderness, or small blisters can occur and often fade within days. Hard arm exercise may need to wait a few days.

How long results last

The SAHARA study found lower sweat and better symptom scores. Results may not last as long as miraDry, so repeat treatments may be needed. The visit itself is much shorter.

What to consider

  • • Type: heated patch used in a clinic
  • • Schedule: 3-4 minutes per underarm, repeated as needed
  • • Cost: varies by clinic and number of visits
  • • Use: trained clinician only
  • • Body area: underarms only

Side effects and reasons this may not be safe for you

  • • Redness and tenderness where the patch was used
  • • Small blisters that resolve over days
  • • Temporary skin darkening
  • • No compensatory sweating
  • • Usually a shorter skin reaction than miraDry

Frequently asked

How is Brella different from miraDry?
Both reduce underarm sweating with heat. miraDry uses microwave energy in a visit of about an hour. Brella uses a short heated patch and may need more repeat visits.
Does Brella hurt?
It can feel warm or hot. Skin numbing may help. Tenderness is often mild and the patch stays on for only a few minutes.
Can Brella be used for hand or excessive foot sweating?
No. Brella is authorized only for underarms. Hand and foot options include iontophoresis and off-label Botox.
