Proper Application of Topical Creams and Ointments
Applying topical medications correctly ensures optimal drug absorption and prevents local adverse effects. Using the right amount, preparing the skin, and applying with proper technique helps treat your condition safely and effectively. This guide explains how to properly measure, apply, and store topical prescription and over-the-counter creams.
Quick Summary

Step-by-Step Guide
Clean and Dry Your Hands
Wash your hands thoroughly with mild soap and warm water for at least 20 seconds before handling the medication. Dry them completely with a clean towel. This prevents introducing bacteria, dirt, or other contaminants into the medication tube or onto compromised skin.
Prepare the Affected Skin Area
Gently clean the affected skin with warm water and a mild, fragrance-free cleanser, unless your doctor advised otherwise. Pat the area dry with a soft cloth rather than rubbing it vigorously. Allowing the skin to completely dry before application helps prevent unwanted irritation or altered drug penetration.
Important: Do not scrub broken, inflamed, or infected skin, as friction can worsen inflammation and damage the skin barrier.
Measure the Prescribed Dose
Squeeze the exact amount of cream recommended by your prescriber. For many medications, dermatologists use the Fingertip Unit (FTU), which is the amount of cream squeezed from the distal skin crease to the very tip of an adult finger. One FTU covers an area approximately the size of two adult handprints placed side by side.
Important: Applying more cream than prescribed will not heal the condition faster and significantly increases the risk of side effects like skin thinning or systemic absorption.
Smooth the Cream Gently Over the Skin
Dab small dots of the cream evenly across the treatment site. Gently smooth the medication into a thin, uniform film over the affected area. Always stroke lightly in the direction of hair growth rather than rubbing back and forth.
Important: Rubbing against the direction of hair growth can force medication into hair follicles, leading to inflammation or an infection known as folliculitis.
Allow Time for Absorption
Leave the treated area uncovered and allow the cream to absorb for roughly 10 to 15 minutes before putting on tight clothing. If your treatment regimen includes a general moisturizer, apply your medicated cream first and wait at least 20 minutes before applying the moisturizer. This waiting period prevents the active medication from being diluted or wiped away.
Important: Never cover the treated area with airtight dressings, bandages, or plastic wrap unless explicitly instructed by your physician, as occlusion dramatically increases drug absorption and potential toxicity.
Wash Your Hands Post-Application
Clean your hands thoroughly with soap and water immediately after you finish applying the medication. This removes any drug residue and prevents accidental transfer to your eyes, mouth, or other sensitive body parts. If you are specifically treating a skin condition on your hands, do not wash them and avoid touching objects for at least 30 minutes.
Cap and Store the Medication Securely
Replace the cap firmly on the tube or jar immediately after dispensing the dose. Store the cream at room temperature, away from direct sunlight, excess moisture, and extreme heat. Avoid keeping topical medications in humid bathroom medicine cabinets, which can degrade the active ingredients.
