Pain relief creams provide localized analgesic effects through active pharmaceutical ingredients that absorb into the skin. Understanding the science behind these medications can promote proper use.
- Blocking pain signals
Ingredients like lidocaine prevent nerve pain signals from reaching the brain. - Reducing inflammation
NSAIDs such as diclofenac inhibit inflammation-causing chemicals that sensitize pain receptors. - Counterirritation effects
Menthol and capsaicin creams overwhelm nerves, reducing their ability to transmit pain.
- Increased blood flow
Rubefacient ingredients like cinnamon oil dilate vessels and boost local circulation to remove pain-inducing metabolites. - Muscle relaxation
Compounds like magnesium sulfate reduce muscle spasms and tension around painful joints and areas.
Recognizing how each ingredient addresses different pain pathways allows optimizing cream selection and usage.
