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.

Blade
How to use microblading needle? Is finest blade the best needles for microblading?

Choosing the thickness of a microblade depends largely on several factors, including the type of eyebrow tattoo, the level of detail required and the individual's tattooing skills. Here are some basic guidelines:

Type of eyebrow tattoo: Detail and line tattoos: finer lines and details can often be achieved with finer needles (e.g. 0.16mm or 0.18mm).

Filling and shading: slightly thicker needles (e.g. 0.20mm or 0.25mm) may be required for better color coverage and shading effects on the skin.

Individual tattooing techniques: Novice tattoo artists may tend to use thicker needles to minimize manipulation time on the skin, while experienced tattoo artists have the flexibility to choose needles of different thicknesses to achieve more varied results.

Skin type: The texture and thickness of different skins can also affect needle selection. Thicker skin may require a slightly thicker needle to ensure that the color and lines penetrate effectively.

Hair condition: The thickness of the client's native hair is also an important factor in choosing the thickness of the needles. Thicker hairs will require slightly thicker needles to ensure that the lines are consistent with the native hairs.

Do I need to use more than one blade during the procedure?

Our blades are made of 304 stainless steel, sharp and tough, usually one blade can support the completion of the entire microblading process. However, due to the different conditions of the customer's eyebrows, the operator may choose different sizes of blades for treatment accordingly, at this time, it may be necessary to use more than one blade in the microblading professional eyebrow microblading process.

The ink can quickly penetrate into the deep layer of the skin, color quickly, and retain color for a long time. It is the best tattoo ink for permanent makeup professional artists to use with machines. hybrid powdered pigment is a pigment based on a combination of water and oil.
