As a dermatologist who has treated numerous patients after microneedling procedures, I’ve seen firsthand how this popular skin treatment can deliver impressive results for many skin concerns. However, I’ve also witnessed complications that could have been addressed earlier with proper knowledge. Today, I want to share important information about recognizing potential issues after microneedling treatments.
Signs of Infection After Microneedling
Microneedling has gained popularity as a minimally invasive procedure to improve various skin conditions like acne scars, wrinkles, and uneven skin tone. The treatment works by creating tiny punctures in the skin that stimulate collagen production. While most patients experience only mild, temporary side effects, it’s crucial to be aware of potential complications.
According to Dr. Mehrabi at BHSkin, “Most people return to wearing their makeup within a day of treatment. However, the skin will be more sensitive to the sun, so it’s advisable to apply sunscreen.” This indicates that mild reactions are expected, but what should raise concerns?
As highlighted by Dr. Irwin on Skintour, infections after microneedling don’t always present in obvious ways. Some may show classical symptoms like swelling, pus, and redness, while others manifest more subtly with persistent irritation and delayed healing.
Normal Side Effects vs. Warning Signs
After microneedling, it’s normal to experience:
- Redness (similar to a mild sunburn)
- Minor swelling
- Skin flaking for 3-5 days
- A slight scratching sensation
- Mild sensitivity
However, you should be concerned if you notice:
- Signs of infection after microneedling that persist beyond a few days
- Severe or worsening pain
- Excessive swelling that increases rather than decreases
- Unusual discharge or pus
- Persistent burning sensation
- Fever or chills
I particularly want to emphasize that prolonged pain, itching, or burning are not normal. As Dr. Irwin notes, “Pain and itching are not normal for skin if they last more than a few days! These are a symptom that something is wrong.”
How to Differentiate Between Normal Reactions and Infections Post-Microneedling
Timeline of Normal Healing
Understanding the typical healing timeline can help you identify potential problems:
- Immediately after treatment: Expect redness and possibly some pinpoint bleeding
- Days 1-2: Continued redness, mild swelling, and sensitivity
- Days 3-5: Skin begins peeling as cell turnover increases
- One week after: Initial improvements may become visible
- Three to six weeks after: Fuller results begin to appear
When to Suspect Infection
Be vigilant for these signs of infection after microneedling:
- Increasing pain instead of decreasing: Normal discomfort should gradually improve, not worsen
- Prolonged redness: While initial redness is expected, it should subside within a few days
- Unusual warmth: Infected areas often feel noticeably warmer than surrounding skin
- Delayed healing: If your skin isn’t improving according to the expected timeline
- Strange textures or appearances: As one patient reported to Dr. Irwin, “My previously smooth skin is now scarred all over with lines, huge pores and a strange texture.”
Types of Complications to Watch For
Based on expert information, there are several types of complications that can occur:
- Bacterial infections: These may cause increasing redness, swelling, and possibly pus
- Fungal infections: Often present as persistent, sometimes itchy rashes that don’t respond to typical treatments
- Viral infections: Especially in those with a history of herpes, which is why people with active herpes should avoid treatment
- Allergic reactions: Often caused by products applied during or after the procedure
- Scarring or texture changes: Permanent skin changes that alter the texture and appearance
Dr. Irwin emphasizes an important point that I strongly agree with: “Please remember that it’s often NOT the microneedling itself that caused the problem. It’s the solution, lotion or cream that they put on the skin before or after the microneedling.” This highlights why knowing exactly what was applied to your skin during treatment is crucial if complications arise.
Prevention and Response to Complications
To minimize risks of complications after microneedling:
- Choose qualified providers: Ensure your procedure is performed by trained professionals
- Disclose your medical history: Including any skin conditions, infections, or allergies
- Follow aftercare instructions meticulously: Keep the treated area clean, avoid touching with unwashed hands
- Use only recommended products: As BHSkin advises, “Avoid using skincare products containing strong, active ingredients” after treatment
- Protect your skin from the sun: Use broad-spectrum sunscreen diligently
- Stay hydrated: Drink plenty of water to support healing
If you suspect infection or complications, don’t wait to seek help. Contact your provider immediately, and if they can’t address your concerns adequately, seek a second opinion from a board-certified dermatologist.
When to Seek Medical Help
If you experience any of the following, seek medical attention promptly:
- Severe or worsening pain
- Spreading redness
- Discharge or pus
- Fever
- Persistent symptoms beyond the expected healing timeframe
Sometimes, complications require specialized testing. As Dr. Irwin suggests, you might need to ask your doctor about:
- Bacterial cultures
- Biopsies to check for fungal infections
- Tissue cultures for difficult-to-identify organisms
Remember, while microneedling is generally safe, early intervention for complications can prevent long-term damage. Knowing the difference between normal healing and warning signs is your best protection against serious complications.
