Application of Transdermal Patches

Transdermal patches, also known as transdermal drug delivery systems, are thin, adhesive patches that are applied to the skin and deliver a predetermined dose of medication through the skin into the bloodstream to produce systemic or localized therapeutic effects. Transdermal patches have the characteristics of easy to tear, convenient to carry, safe drug dosage, etc. Particularly suitable for daily health care and skin beauty industry, its types are very diverse and extensive. For example, shoulder pain relief patches, knee pain relief patches, dampness elimination and detoxification foot patches, womb warming patches, vitamin patches, etc. In addition, this non-invasive mode of drug delivery allows for long-term stable absorption and is an alternative mode of drug delivery to injections and oral medications. It is also applicable to the biomedical industry to treat diabetes, neurological diseases, etc.

• Health and Wellness

Some transdermal patches containing vitamins, minerals and other nutrients can be absorbed through the skin to provide the body with the required nutrients, thus playing a health care role. In addition, some transdermal patches with effects such as improving sleep quality and relieving fatigue are also gradually emerging in the market. Menstrual heating patches are made of high-quality breathable ingredients that can help relieve pain. Specific sizes of steam eye masks and foot warmer patches are designed to make the patches fit the skin better and increase comfort, and the heating is accompanied by pain relief through the addition of herbs.

•  Cosmetics

Transdermal patches are widely used in the field of cosmetology. Transdermal patches containing ingredients such as spot removal, whitening, anti-aging, etc., can be absorbed through the skin to act directly on the deeper layers of the skin to achieve better cosmetic results. In addition, transdermal patches can also provide personalized beauty solutions according to individual skin needs, to meet the beauty needs of different people. For example, acne patches for the treatment of acne, whitening masks, face molding patches, collagen patches, weight loss patches and eye anti-aging patches, etc.

•  Pharmaceuticals

Transdermal patches are particularly widely used in the field of medicine, which, as a new type of drug dosage form, has the advantages of convenience, safety and easy control. Transdermal patches can directly deliver drugs to the skin surface, through the skin absorption into the blood circulation, so as to reach the lesion site to play a therapeutic role. This way of drug delivery avoids the stimulation and first-pass effect of oral drugs on the gastrointestinal tract, and also reduces the pain and infection risk of injection drug delivery.
