Hyperhidrosis, or excessive sweating beyond what is required for normal thermoregulation, affects a meaningful proportion of the population and can occur in the underarms, palms, soles or elsewhere. It arises from overactivity of the sweat glands, sometimes without a clearly identifiable underlying cause (primary hyperhidrosis), and can have a significant impact on daily comfort and confidence, despite rarely being discussed openly.

Scars form as part of the body’s natural wound-healing process, and their eventual appearance is influenced by factors including wound depth, tension across the healing site, individual healing tendency, and infection during the healing period. Some patients experience scarring that is more pronounced than typical, whether from surgery, injury or conditions such as acne, and seek treatment to improve its appearance.

While this article is written primarily for women, this concern is frequently raised by patients on behalf of a male partner or family member, so it is worth including. Gynecomastia refers to enlargement of male breast tissue, arising from a hormonal imbalance between oestrogen and testosterone, and can occur for a range of reasons including puberty, certain medications, and other underlying health conditions that warrant medical assessment before any aesthetic treatment is considered.

• Clinical-strength topical antiperspirants: often considered as a first-line measure before more involved treatment is explored.
• Neuromodulator injections: this treatment category, more commonly associated with facial lines, may also be used to temporarily reduce the activity of sweat glands in areas such as the underarms, with effects that diminish gradually over a period of months, similar to their facial application.
• Iontophoresis: a device-based treatment sometimes used for palm or sole hyperhidrosis, involving a mild electrical current passed through water to temporarily reduce sweat gland activity.
• Referral for underlying assessment: because hyperhidrosis can occasionally relate to an underlying medical condition, a general practitioner assessment is a reasonable first step before pursuing targeted aesthetic treatment.

Options for improving the appearance of scarring may include silicone-based topical treatments, corticosteroid injections for certain raised scars, laser treatment to address colour or texture, and, in some cases, surgical revision for scars that have healed with significant tension or irregularity. Timing matters considerably in scar treatment, as scars continue to mature and often improve naturally over a period of twelve to eighteen months following the original injury, meaning premature intervention may not always be necessary or advisable.

Following appropriate medical assessment to rule out or address any underlying hormonal cause, treatment options may include surgical removal of excess glandular tissue, sometimes combined with liposuction to address surrounding fatty tissue, depending on the specific presentation.

For treatments in this category, practitioner experience specific to the relevant anatomical area is particularly important, given both the technical nuance involved and the heightened sensitivity many patients feel. Patients are encouraged to ask directly about a practitioner’s specific experience and training in the relevant procedure, and should feel entitled to seek a second opinion or a different practitioner if they do not feel sufficiently comfortable or confident in the initial consultation, without any sense of obligation to proceed simply because an initial conversation has taken place.

For patients managing hyperhidrosis, breathable, natural fabrics and moisture-wicking clothing may help manage daily comfort alongside any clinical treatment pursued, and are a reasonable, low-cost complement to more targeted intervention.

For women considering treatment related to changes following childbirth, allowing adequate time for the body’s natural postpartum recovery and hormonal stabilisation, generally at least twelve months, is typically advised before considering aesthetic treatment for concerns that may resolve or improve naturally during this period.

For patients managing scarring, consistent sun protection over the healing scar, avoidance of tension on the healing wound where possible, and early, gentle scar massage once a wound has sufficiently closed (as advised by a treating practitioner) may support more favourable natural healing before any further intervention is considered.

For several of the concerns discussed in this article, particularly hyperhidrosis and gynecomastia, an underlying general health assessment is a sensible first step, as both can, in some instances, relate to broader hormonal or metabolic factors that are worth understanding before pursuing targeted aesthetic treatment. A general practitioner is well placed to conduct this initial assessment and provide referral to a specialist where appropriate.
