Rosemary oil can indeed cause a tingling sensation on the skin for some individuals. This tingling sensation is due to the active compounds present in rosemary oil, such as camphor and cineole. These compounds have stimulating properties that can increase blood circulation and provide a mild warming effect on the skin.

It's important to note that the tingling sensation should be mild and temporary. If you experience any discomfort or irritation that persists or worsens, it is advisable to discontinue use and consult a dermatologist.

Additionally, it's worth mentioning that individual sensitivities can vary, and not everyone may experience a tingling sensation when using rosemary oil. As with any skincare ingredient, it's always recommended to perform a patch test before incorporating it into your routine to ensure compatibility with your skin.
