    Yes, Brella works on all skin types and is proven to be safe and well tolerated.2,3

  • 6.

    Brella is for adults, regardless of their skin type, who are consistently bothered by excessive underarm sweating even when they are not exercising or are too hot.1

  • 7.

    What happens during a Brella treatment?


    The Brella SweatControl Patch consists of a sodium sheet with an adhesive backing. When the Patch is applied to the underarm, the sodium comes in contact with the water in your sweat, generating heat. The heat precisely targets your underarm sweat glands to significantly reduce sweat production.1,4

  • 8.

    How long is a Brella procedure?


    Brella is a quick, comfortable, and easy in-office treatment. It takes up to three minutes to treat each underarm and only one underarm is treated at a time.1

  • 9.

    What will I feel during the procedure?


    During the procedure the treated area may start to feel warm as the time passes. You may also feel some stinging or pins and needles or other sensations that may become more noticeable as the treatment takes place. This will be an indication that the Patch is interacting with your sweat and the treatment is working. In our clinical study, Brella-treated patients reported an average discomfort level of 2.4 (on a scale of 1-10 where 1 is minimal).3

  • 10.

    What side effects might I experience after treatment?


    Brella is safe and generally well tolerated. You may experience treatment-related minor redness or irritation, which typically resolves immediately after the procedure. Some patients had tenderness or sensitivity that lasted up to 48 hours.1,3

  • 11.

    How long does it take to start seeing the effects of the treatment?


    Many patients see results within a few days. It is important to understand that this treatment reduces excessive underarm sweating. It will not stop sweating completely. If you exercise or are in a hot/muggy climate, you may still sweat in your underarms.3

  • 12.

    How will Brella impact my day? How will it make me feel?


    • After a single treatment, patients experience significant improvement in confidence including reduced feelings of frustration and embarrassment.5
    • Reduced sweat production may lead to a reduction in showering multiple times a day, high dry-cleaning bills, frequency of applying antiperspirant, need to frequently replace stained shirts and tops, or need to carry extra change of clothing.5
  • 13.

    How do I prepare for my Brella treatment?


    You will need to shave or clip your underarms at least 48 hours before treatment. On the day of your appointment, wear loose-fitting clothing (i.e., a tank top). Make sure you drink plenty of water, so you are hydrated. Avoid wearing deodorant or antiperspirant to the appointment, if possible.1

  • 14.

    Is there any downtime with this treatment? Can I resume normal activities immediately post treatment?


    There is no downtime after a Brella treatment.1,2

  • 15.

    If my sweat is reduced in one area, will I sweat more in another area?


    This is called compensatory sweating and it is a common side effect of treatments for excessive sweating. In our study, this only happened to one patient,3 so it is not expected to be a common side effect, but it could happen. As results from a Brella SweatControl Patch treatment are temporary, if compensatory sweating occurs, it is expected that it will also be temporary.

  • 16.

    When can I use deodorant/antiperspirant or shave again?


    You can resume your normal hair removal, deodorant, or antiperspirant use after the treatment. But, if your underarms feel irritated or tender, wait until it resolves.1

Brella works for up to 3 to 4 months and sometimes longer in all skin types…Bravo Brella!
