Injectable compositions and methods of treating skin can help improve hydration, elasticity and/or texture of the skin. The compositions can be based on crosslinked hyaluronic acid matrices made with low molecular weight hyaluronic acids.

Compositions and methods for improving skin appearance

Disclosed herein are soft tissue fillers, for example, dermal and subdermal fillers, based on hyaluronic acids and pharmaceutically acceptable salts thereof. Some of the hyaluronic acid-based compositions can include a therapeutically effective amount of at least one anesthetic agent, for example, lidocaine. Compared to conventional compositions that include lidocaine, some of the hyaluronic acid-based compositions disclosed herein can have an enhanced stability, for example, when subjected to sterilization techniques or when stored for long periods of time. Methods and processes of preparing such compositions are also provided.

Hyaluronic acid-based gels including lidocaine

An injectable monophase hydrogel is provided that is made of a reaction mixture of hyaluronic acids having different molecular weights.

Injectable monophase hydrogels

Disclosed herein are cohesive soft tissue fillers, for example, dermal and subdermal fillers, based on hyaluronic acids and pharmaceutically acceptable salts thereof. In one aspect, hyaluronic acid-based compositions described herein include a therapeutically effective amount of at least one anesthetic agent, for example, lidocaine. The present hyaluronic acid-based compositions including lidocaine have an enhanced stability and cohesivity, relative to conventional compositions including lidocaine, for example when subjected to sterilization techniques or when stored for long periods of time. Methods and processes of preparing such hyaluronic acid-based compositions are also provided.

The disclosure provides hyaluronic acid (HA) gel formulations and methods for treating the appearance of the skin. The formulations contain hyaluronic acid and at least one additional ingredient. Methods for treating lines, wrinkles, fibroblast depletions, and scars with the disclosed composition are provided as well.

Heat stable hyaluronic acid compositions for dermatological use

The present specification generally relates to an injectable dermal filler composition that includes crosslinked hyaluronic acid-based polymer and an antioxidant.

Stable hydrogel compositions including additives

Dermal filler hydrogel compositions, methods of making them, and methods of using them to treat soft tissue conditions, such as wrinkles, are provided. The compositions contain a crosslinked hyaluronic acid-based polymer and one or more additional ingredients, and are stable to sterilization by heat and/or pressure treatment. The additional ingredients include vasoconstrictive agents, antioxidant agents, such as a ascorbic acid agents, and/or anesthetic agents.

Methods and processes of preparing such hyaluronic acid-based compositions are also provided.

An injectable monophase hydrogel is provided and is made of a reaction mixture of a high molecular weight hyaluronic acid and a low molecular weight hyaluronic acid.
