A delivery system for sunscreen products that applies a dry, waterproof sunscreen composition to the skin. The delivery system for suncare products of the present invention is designed to apply only the required amount of sunscreen composition to the skin without excess. The sunscreen composition is applied to an article such as paper, nonwoven cloth or porous plastic which is subsequently rubbed onto the skin. Alternatively, the sunscreen may take the form of a wafer or a bar with or without a support article. A delivery system for suncare products which include dihydroxyacetone in order to produce a semi-permanent color that gives the appearance of a natural suntan is described which utilizes the same self-leveling principle as the delivery system for suncare products containing sunscreen compositions.

Delivery system for suncare products

A novel device and method for delivering a liquid containing an active ingredient to a treatment site on the skin is disclosed. The device is useful for treating lesions or abnormal skin features such as corns, warts, calluses, bunions, actinic keratoses and hard hyperkeratotic skin as is often found on the face, arms, legs or feet.

Device for delivery of dermatological ingredients

Compositions and processes for medicating human skin disorders using hydrogen peroxide as an active antimicrobial agent. The composition includes essentially hydrogen peroxide, a non-volatile carrier-solvent, and water. A predetermined final hydrogen peroxide concentration is achieved through evaporation of water. In this manner, hydrogen peroxide concentration may be controlled to avoid deleterious effects. Other therapeutic agents such as alpha hydroxy acids may also be added to the composition for treating various skin ailments.

Method and composition for skin treatment

Compositions and processes for medicating human skin disorders using hydrogen peroxide as an active antimicrobial agent. However, active agents other than hydrogen peroxide may be substituted. In the case of hydrogen peroxide, the agent is solubilized in carrier materials that are completely miscible with water and are nonvolatile. The use of such materials as carriers allows for a controlled release of nascent oxygen at a skin treatment site in the case of hydrogen peroxide.

Method and composition for controlled delivery of nascent oxygen from

Various embodiments of a delivery system for the effective and efficient administration of low viscosity cosmetic and dermatological ingredients without the use of plasters or repetitive applications that are currently necessary. The claimed embodiments eliminate migration of the low viscosity application liquid to areas where treatment is not required and/or sensitive areas of the patient's body which could be adversely affected if contacted by the application liquid.
