Cold compress is based on traditional cold compress methods (such as cold water, ice water, alcohol, etc.). ), a new TDDS drug release system based on polymer gel, is the core, which consists of a backing layer, a gel layer and an anti-sticking layer. Qing Feng de adopted this principle and suggested its use.

The medicinal components are combined with hydrogel, and through hydration, the medicinal components can quickly penetrate the fat layer, penetrate into subcutaneous tissue, reach the focus and act on the affected part, thus achieving the effects of cold compress and pain relief, transdermal absorption and slow release administration.

Compared with the traditional cold compress method, it has the following advantages:

1, convenience: no special requirements, can be used in various places; Can be attached to all parts of human body, does not affect human activities, is easy to attach and uncover, has no pollution or residue, and is convenient to carry.

2. Comfort: The gel layer contains more than 60% water, which is close to the water contained in human cells. This gel is soft and comfortable to the touch.

3. Long-term effect: the water and components in the gel layer evaporate slowly and continuously, and the action time after application can be as long as 12 hours without repeated operation.

4, small irritation: cold compress is mild and non-irritating to the skin, and will not produce adverse reactions such as hair standing and chills.
