Targeted Sweat Reduction
Hyperhidrosis injections are a non‑surgical option used to reduce excessive sweating in areas such as the underarms, hands, or face. By temporarily reducing the activity of sweat glands in the treated area, this approach can help individuals who experience persistent or disruptive sweating.
What are hyperhidrosis injections?
Hyperhidrosis injections use targeted muscle‑relaxing medication to reduce the activity of sweat glands in specific areas. In people with hyperhidrosis, the nerves that trigger sweating can be overactive, leading to moisture even in cool temperatures or at rest. By interrupting these signals, the treated area may produce less sweat for a period of time.
Â
During your consultation, your practitioner will assess the severity and pattern of sweating, review your medical history, and determine whether this treatment is appropriate. Common treatment areas include the underarms, palms, soles, and sometimes the scalp or face. The procedure involves a series of small injections placed just beneath the skin, guided by the distribution of sweat glands in the area. Most individuals tolerate the treatment well and can return to normal activities shortly after.
Who is this treatment suitable for?
Hyperhidrosis injections may be considered by adults who experience excessive sweating that affects daily activities, clothing choices, or comfort. Suitability can only be confirmed following a comprehensive consultation with a qualified practitioner, which includes assessment of sweating patterns, medical history, and individual goals.
Â
A personalised consultation is required to confirm whether this treatment is appropriate and safe for you, taking into account:
-
Location and severity of sweating
-
Skin sensitivity and medical history
-
Previous treatments or topical products used
-
Individual expectations and reasons for seeking treatment
How do hyperhidrosis injections work?
Hyperhidrosis injections work by temporarily interrupting the nerve signals that activate sweat glands in the treated area. Small amounts of muscle‑relaxing medication are placed just beneath the skin, targeting the junctions where nerves communicate with the sweat glands. By reducing this activity, the treated area produces less sweat for a period of time, with effects developing gradually over the following days.
Results, timing and downtime
Responses vary between individuals. Many people notice a reduction in sweating within several days, with full effects typically developing over 1–2 weeks. Downtime is usually minimal, though temporary redness, swelling, or mild tenderness may occur depending on the area treated.
Individual results vary and cannot be guaranteed.
Risks and considerations
All medical and cosmetic procedures carry risks. These will be discussed during your consultation to support informed consent.
Â
Potential considerations may include:
-
Temporary discomfort, redness, or bruising
-
Mild weakness in nearby muscles (e.g., grip fatigue when treating palms)
-
Dryness or compensatory sweating in other areas
-
The possibility that further treatment or no treatment may be recommended
-
Variability in individual response
Aftercare
Aftercare instructions will be provided by your practitioner and should be followed as advised. These may include avoiding vigorous exercise immediately after treatment, refraining from applying deodorant for a short period (for underarm treatments), and monitoring for any unexpected symptoms. You should contact your practitioner or seek medical advice if you experience concerning effects following treatment.
