Customizing Microneedling for Acne Scar Treatment
Microneedling is a powerful treatment for various types of acne scars, including ice pick, boxcar, and rolling scars. Customizing the treatment with precise needle depth, speed, and pressure can significantly improve results and help patients achieve smoother, clearer skin. This guide breaks down the customization process for each scar type.
Needle Depth Specifications for Acne Scar Types
Microneedling treatment of acne scars requires adjustment in the depth of the needle to achieve best results. The depth variation is demanded by the type of scars to get to the area that actually needs attention. Below is a guide on the optimum needle depth for each kind of acne scar, allowing treatments according to the severity and depth of the scars for maximum effectiveness.
Scar Type | Session 1-2 | Session 3-4 | Session 5+ |
Ice Pick Scars | 1.5mm | 2.0mm | 2.0–2.5mm |
Boxcar Scars | 1.0–1.5mm | 1.5–1.8mm | 1.8–2.0mm |
Rolling Scars | 1.5mm | 1.8mm | 2.0mm |
Speed Settings for Microneedling Scar Treatment
Speed settings are a very important ingredient in microneedling treatments to balance effectiveness and minimize discomfort. By adjusting the speed, the skin gets the right amount of penetration and stimulation it needs. Below is a guide to speeds for various phases that one could set in conducting a microneedling treatment.
Speed Setting | Usage | Purpose |
8–10 Hz | Sensitive Areas | For delicate areas of the skin with minimal irritation. |
12–14 Hz | Standard Treatment | For general treatment to address deeper scarring. |
14–16 Hz | Scar Revision | To focus on scar tissue and increase penetration. |
10–12 Hz | Scar Edges | For softer treatment of edges and blending of scar lines. |
Speed Settings by Treatment Phase
The most important speed settings for good results in microneedling treatments are as follows.
Phase | Speed | Purpose | Duration |
Initial Pass | 12 Hz | Even penetration over the treatment area. | Full coverage of the treated area. |
Focused Scar Treatment | 14–16 Hz | Target deeper scar tissue for improved results. | 3–4 passes over the scars. |
Final Pass | 10–12 Hz | To blend the treated area for a smoother finish. | Light pass for blending edges. |
Pattern Selection for Microneedling Treatment
The selection of the pattern during microneedling is important in the treatment of different types of acne scars. Different patterns allow for targeted treatment in specific areas, ensuring even coverage and optimal results. The table below outlines the most common microneedling patterns, their applications, and the types of scars they are best suited for.
Pattern Type | Application | Best For |
Cross-Hatching | First pass: Vertical lines. Second pass: Horizontal lines. Spacing: 1–2mm. | Large scars (e.g., rolling, boxcar). General scar blending. |
Circular Motion | Direction: Clockwise. Diameter: 5–8mm circles. Overlap: 50%. | Ice pick scars. Small boxcar scars. |
Fan Pattern | Angle: 45 degrees. Spacing: 2mm. Pressure: Varies. | Large areas. Rolling scars. Blending scar edges. |
Pressure Variation for Microneedling Treatment
Variation in pressure while undertaking microneedling treatments ensures the right depth and coverage in relation to various scar or skin conditions. Pressures during the different stages of treatment could affect the results where light pressure is applied to sensitive areas, while firm pressure is used on deep scars. Below is the table of the pressure used in microneedling, and its application for use on different treatment areas.
Pressure Level | Usage | Purpose |
Light Pressure | 2–3 Newtons | For sensitive areas, initial passes, and peripheral skin. |
Medium Pressure | 4–5 Newtons | Standard treatment for rolling scars, boxcar edges. |
Firm Pressure | 6–7 Newtons | Deep scars, ice pick centers, or thicker skin areas. |
Pressure Modulation Techniques
Varying the level of pressure during treatment will enable practitioners to better address specific areas and thus assure optimal results. Below is a guide through pressure modulation techniques, describing in detail how pressure levels change during different stages of treatments and for different scar types.
Technique | Usage | Purpose |
Graduated Pressure | Start light, increase to medium, apply firm pressure on deep scars. | To ensure gradual, controlled treatment. |
Zone-Specific Pressure | Light pressure for edges, medium for central scar areas, firm for deep scars. | Targeted pressure for various scar depths and areas. |
Zone-specific pressure refers to the variation in pressure applied during microneedling based on the location of the scar. This technique ensures a more effective treatment by tailoring the pressure to the specific needs of each area. Below is a breakdown of the pressure levels used in different zones of the treated area:
Zone | Pressure Level |
Scar center | Firm |
Edges | Medium |
Transition areas | Light |
Surrounding skin | Very light |
This targeted approach helps optimize results while minimizing discomfort and maximizing skin healing.
Microneedling Treatment Integration Protocol
