Is Secondary Numbing Essence Safe to Use on Broken or Open Skin?

In the semi-permanent makeup (SPMU) industry, the use of numbing essences is critical to ensure client comfort. However, questions often arise about their safety, especially when applied to broken or open skin. Secondary numbing essence typically refers to a topical anesthetic applied after the initial numbing phase to prolong or enhance the effect. It is essential to understand the potential risks and recommended safety protocols.

What Is Secondary Numbing Essence?

Secondary numbing essence usually contains lidocaine, prilocaine, or other local anesthetics designed to reduce pain during procedures such as microblading, permanent makeup, or tattooing. It is applied after the skin has been initially numbed or after the procedure has started to maintain numbness.

Is It Safe to Apply Secondary Numbing Essence on Broken or Open Skin?

The general consensus in dermatology and SPMU practice is that numbing agents containing potent anesthetics should be used with caution on broken or open skin. According to the American Academy of Dermatology and dermatological anesthetic guidelines, topical anesthetics can be absorbed more rapidly through broken skin, increasing the risk of systemic toxicity. Therefore, applying secondary numbing essence on open wounds, abraded skin, or actively bleeding areas is not recommended.

Potential Risks of Using Numbing Essence on Broken Skin

• Increased absorption and toxicity: Faster absorption can lead to lidocaine overdose symptoms such as dizziness, numbness beyond the skin, and in rare cases, cardiac complications.
• Delayed healing and infection: Some numbing agents may interfere with skin regeneration or promote bacterial growth if applied on non-healed skin.
• Local irritation or allergic reactions: Broken skin is more susceptible to irritation or contact dermatitis from chemical ingredients.

Best Practices for Using Secondary Numbing Essence Safely

1. Perform a skin assessment: Always check the skin condition. Avoid numbing agents on actively broken or bleeding skin.

2. Use approved products: Only use numbing essences that are approved for SPMU, contain safe anesthetic levels, and comply with health regulations.

3. Follow manufacturer instructions: Strict adherence to recommended dosages, application times, and re-application limits is crucial.

4. Allow initial healing: If skin is broken due to previous procedures, wait until the skin has sufficiently healed before reapplying numbing essence.

5. Client education: Inform clients about the risks of applying numbing essence on open skin or wounds.

What Do Professional Guidelines Say?

The PMU industry guidelines from associations such as the Society of Permanent Cosmetic Professionals (SPCP) and the American Academy of Micropigmentation recommend avoiding topical anesthetics on open wounds. Additionally, many anesthetic manufacturers explicitly state that their products are not for use on broken or mucous membranes unless specified, to avoid systemic complications.

Conclusion

Secondary numbing essence is a valuable component in semi-permanent makeup procedures but should never be applied to broken or open skin due to safety concerns including increased absorption, toxicity risk, and infection. Following professional protocols and manufacturer guidelines ensures client safety and optimal results.
