Numbing cream, also known as topical anesthetic, reduces pain and discomfort on the skin’s surface. These creams are commonly used before procedures like injections, minor surgical interventions, and cosmetic treatments such as waxing, piercings, or tattooing. By temporarily dulling sensations, numbing creams make these experiences more tolerable. This article guides proper use, covering application factors, techniques, and safety considerations.
How Numbing Creams Work
Numbing creams contain active ingredients that temporarily block nerve signals in the skin. Common active ingredients include local anesthetics like lidocaine, benzocaine, and prilocaine. When applied, these substances penetrate outer layers, stopping nerve endings from sending pain signals to the brain.
This creates a localized numbing effect, reducing sensation without a complete sensory block. The numbing effect typically begins within 30 to 60 minutes, allowing for a more comfortable experience during procedures.
Factors Influencing Application Amount
The appropriate amount of numbing cream depends on several factors. The active ingredient’s concentration is important; higher concentrations generally require less product for the desired effect. Always check the product label for its specific concentration.
Larger areas require more cream, but stay within recommended limits to prevent risks. Skin sensitivity also plays a role; more sensitive regions may benefit from a slightly thicker application, adhering to safety guidelines. Different procedures, like minor injections versus larger tattoo areas, may have varying recommendations. Always consult the product’s instructions for safe and effective dosage.
Proper Application Techniques
Proper skin preparation is essential for effective numbing cream application. The area should be clean and dry for optimal absorption before applying the cream.
Layer thickness varies by product and procedure; some creams are rubbed in, while others require a thick, un-rubbed layer. For many creams, especially those with lidocaine and prilocaine, applying a thick layer and covering it with an occlusive dressing, like plastic wrap, enhances absorption and prolongs the effect. The cream typically needs to remain on the skin for 30 to 60 minutes to take full effect. Remove any excess cream before the procedure.
Safety Precautions and Warnings
Using numbing cream safely requires careful attention to potential risks. Applying excessive amounts, covering too large an area, or applying to broken or irritated skin can lead to systemic absorption of active ingredients, causing serious adverse effects.
Over-absorption symptoms may include lightheadedness, dizziness, vision problems, irregular or slow heartbeat, or difficulty breathing. If these occur, remove the cream immediately and seek medical attention. Allergic reactions are possible, so perform a patch test on a small, inconspicuous skin area before widespread application.
Contraindications include certain medical conditions, interactions with other medications, or use on infants and young children without specific medical advice. Always consult a healthcare professional if you have underlying health concerns, are taking other medications, or experience unexpected or severe reactions.
