For centuries, patches have been used to deliver a targeted concentration of ingredients to treat a variety of conditions. They first appeared in ancient Chinese medicine with medicinal herbal plasters. More recently, patches have been scientifically developed in the medical field to convey nicotine, hormones and pain medications.   But patches aren’t just for medicinal use anymore. Cosmetic patches can help visibly diminish the appearance of fine lines, re-hydrate skin and treat acne. Patches have been proven to produce faster, more noticeable and longer-lasting results.
