Sweat glands, also known as sudoriferous or sudoriparous glands, from Latin sudor, meaning 'sweat', are small tubular structures of the skin that produce sweat. Sweat glands are a type of exocrine gland, which are glands that produce and secrete substances onto an epithelial surface by way of a duct. There are two main types of sweat glands that differ in their structure, function, secretory product, mechanism of excretion, anatomic distribution, and distribution across species...

A treatment of sweat glands in a target region of skin includes generating electromagnetic radiation having a wavelength of about 1,064 nm to about 1,800 nm. To decrease sweat production in a plurality of sweat glands, the electromagnetic radiation is delivered to a dermal interface defined by a dermal region and a subcutaneous fat region in the target region of skin to cause thermal injury to at least one of the dermal region, the subcutaneous fat region or the dermal interface. An epidermal region of the skin can be cooled at least one of before, during or after delivering the electromagnetic radiation to the dermal interface in the target region of skin.

Botulinum toxin may be used to inhibit the cascade of events leading to acne. Results in preliminary studies have been dramatic. Withoout wishing to be bound by this theory, it is believed that botulinum toxin achieves this result through parasympathetic effects, inhibiting sweat gland activity, stimulating keratinocyte locomotion, anti-inflammatory effects, and possibly anti-androgenic effects. Botulinum toxin can play an important role in decreasing and even preventing the formation of acne.

The invention relates to sweat activity measurement, e.g. for determining a physiological state of a subject, embodied by a method as well as a kit with an immittance measuring circuit and electrodes with contact electrolyte. Sweat activity is considered a transport phenomenon and can be defined as a flux, e.g. gram water per skin area per second. Prior art methods determining water absorbed per gram dry stratum corneum measures skin moisture and do not truly reflect sweat activity. A periodic signal with frequency of 60 Hz or lower is applied to reduce contribution from complex admittance of the skin, and skin conductance is measured as a degree of sweat activity. The contact electrolyte allows filling of sweat ducts with sweat from sweat glands, this may be characterized in that it does not substantially fill the sweat ducts when being positioned on the skin and / or in that it has a re-absorption time constant from the sweat ducts into the Epidermis of less than 15 min.

Antiperspirant/deodorant active for no white residue sticks and soft solids
Antiperspirant actives that produce practically no visible white residue, even against a black background is provided by the reduction of the particle size, using a refractive index modifier, to a point where the antiperspirant active on application provides no discernible whiteness.When formulated into an antiperspirant stick, the antiperspirant actives produce an improved combination of functional properties, including excellent antiperspirancy, smooth skin feel, nontacky, quick drying and leave no visible residue.The exceptionally high surface area of the antiperspirant active results in rapid and efficient delivery of the active to the sweat glands and possible absorption. The absence or reduced quantity of suspending and flow enhancing agents, of gellant and surfactant, is believed to improve the antiperspirant active's ability to physically reach the sweat glands and improve efficacy.

A new method for the inhibition of human sweating and body malodour is described. An agent capable of blocking calcium channels in the secretory coil cells of human sweat glands is topically applied; on reaching the secretory coil cells, the action of this agent results in reduced sweat production. Preferred agents are natural plant extracts. The transport of the agent to the secretory coil is preferably enhanced in some way, for example by iontophoresis or the use of a skin penetration enhancer. Antiperspirant products comprising a calcium channel blocking agent and a pore-blocking antiperspirant active are also claimed.

The invention provides an integrated framework for detecting peripheral sympathetic responses through imaging. The measurements may be performed on three facial areas of sympathetic importance, that is, periorbital, supraorbital, and maxillary. Because the imaging measurements are thermal in nature and comprise multiple components of variable frequency (i.e., blood flow, sweat gland activation, and breathing), wavelets are used as the image analysis framework. The image analysis may be grounded on GSR signals.

Non-pathological, physiologically normal sweating is inhibited through use of an a muscarinic anticholinergic amine that blocks parasympathetic stimuli from cholinergic nerve fibers to an innerved sweat gland. The anticholinergic agent is included in a form adapted to be topically applied to commonly sweaty areas of the body. Side effects are minimized by employing amines which are charged at physiological pH, thereby minimizing their ability to cross biological membranes. The most prefered anticholinergic agents are salts of quaternary amines (quaternary ammonium salts) which are always charged.
