+You can also use the `removeStyle()` function to remove injected styles from the page. It accepts the following parameters:

+| type | string | no       | `base`  | `base` `core` | If `core` is defined, the core styles will be removed from the page, if nothing is defined, `base` styles will be removed as default value |
+
+```jsx
+import { removeStyle } from 'react-tooltip'
+
+removeStyle() // removes the injected base style of ReactTooltip
+removeStyle({ type: 'core' }) // removes the injected core style of ReactTooltip - this can affect the basic functionality of ReactTooltip
