Why do you use the finger tips to whilst doing rubbing in method?

Using the fingertips while performing the rubbing-in method for drug application has several advantages and reasons behind its practice:

1. Accuracy and Precision: The fingertips provide better control and precision in rubbing the medication onto a specific area. They allow for more targeted application, ensuring that the medication is applied where it is needed without excess waste or spreading to other areas.

2. Pressure Regulation: The fingertips enable better regulation of pressure during the rubbing-in process. This is particularly important for topical medications that require gentle application to avoid skin irritation or damage. The sensitivity of the fingertips helps in applying the right amount of pressure for effective absorption without causing discomfort.

3. Enhanced Absorption: Rubbing the medication with the fingertips generates a certain degree of friction, which helps in enhancing the absorption of the drug through the skin. The friction created by the fingertips promotes better penetration of the medication into the underlying tissues.

4. Warming Effect: The rubbing motion with the fingertips creates a slight warming effect on the skin. This warmth helps in dilating the blood vessels near the application site, leading to increased blood flow to the area. Improved circulation facilitates better absorption of the drug.

5. Activation of Nerve Endings: The gentle rubbing with the fingertips stimulates nerve endings in the skin. This can assist in reducing local pain or discomfort and provide a soothing effect in the affected area.

6. Avoidance of Contamination: Using the fingertips allows for better control over the hygiene and cleanliness of the application process. It helps prevent contamination of the medication or the surrounding area, reducing the risk of infections or cross-contamination.

7. Improved Patient Comfort: Rubbing with the fingertips often feels more comfortable and convenient for patients compared to using other application tools or methods. It allows for a gentler and more personalized touch during the medication application process.

Overall, using the fingertips for the rubbing-in method offers greater control, precision, and comfort while ensuring effective absorption of the medication. This technique is commonly employed for various topical formulations, such as creams, gels, ointments, and lotions, to maximize their therapeutic effects.
