Microneedling is praised by literally everyone. It seems like it’s a solution to basically every skin concern. But because of its popularity and high demand, this treatment is offered by everyone, certified or not.

That might worry you – and for a good reason. Practitioners shouldn’t be able to offer skin treatment they weren’t trained for. Researching the treatment, you might have googled phrases like microneedling bad results and microneedling gone wrong to see what is the worst that can happen.

Well, microneedling done the way it’s supposed to is safe. But done by a non-expert in a substandard way, microneedling gone wrong can happen, as the risks and side effects are increased.

Let’s explain what can happen if microneedling is done recklessly, and not taken as seriously as it’s supposed to be.

This issue shouldn’t arise during the procedure. After all, you are doing the procedure to get rid of it in the first place. However, with improper use, it’s possible to make this condition worse.

Scarring occurs when microneedling is performed incorrectly. Mostly, by pressing the device too hard or needling the area too many times.

This issue is more common for dermarollers, especially among home users. However, it isn’t unheard of for it to happen in salons either when booking an appointment with an untrained and inexperienced technician.

Another mistake untrained technicians can make is with a dermapen. Dermapen tool is used exclusively in salons and is considered a better option than dermaroller because its needles are adjustable.

The skin isn’t the same thickness everywhere and thinner parts should be treated with shorter needles, not puncturing deeper than necessary. Not adjusting the dermapen needles properly can also be the cause of the scarring and bruising.

Hyperpigmentation + Inflammation

Although you might’ve chosen to do microneedling to get rid of hyperpigmentation, you actually might worsen it. Usually microneedling is accompanied by a minor inflammation, but if done properly that side effect subsides not long after the end of the procedure.

Post-inflammatory hyperpigmentation (aka the darker stains on the skin) can affect anyone, but it’s more likely to happen to people with a darker complexion. Hyperpigmentation occurs when pigment-producing cells are overstimulated to produce melanin, the pigment. That process starts due to inflammation and results in discoloration or staining of the skin.

Inflammation is the main reason why microneedling sessions need to be spaced apart. Your skin requires time to heal. If you interrupt the healing process with another session you will damage your skin and make it more inflamed. And the whole point of safe microneedling is to reduce unnecessary inflammation. More on that in a bit.


Infections during microneedling are caused by contaminated needles in the device or lack of proper aftercare.

To avoid the microneedling risk of infection, the tip of the tool (needle cartridge) needs to be new, unused and sterilized. In a salon, the technician knows how to do that properly. But at home people disregard the importance of this.

Some infections are obvious (swelling, pus and redness), but they can be much more subtle as well. Your skin might just be irritated and seemingly not healing. Swollen lymph nodes are also a symptom of an infection.

If you suspect an infection, you should visit a doctor as soon as possible. You will probably be prescribed antibiotics.


A granuloma is a tiny cluster of white blood cells and other tissue. They form as a reaction to infections, inflammation, and irritation.

Skin granulomas are a harmless skin condition that causes raised, sometimes pink-colored bumps under the skin. They can be caused by substances that irritate the skin, or when an infection starts as this is a body’s natural way of containing the infection.

Granulomas are very rarely caused by microneedling, but if the treatment is done poorly there is a possibility of granuloma forming. More often, the granuloma is formed after the treatment.

A lot of skincare products are formulated to be topical and only used at the skin’s surface, not go deep into the skin layers – therefore, they’re not supposed to be used for microneedling, but sometimes, due to negligence.

If they contain harmful ingredients (such as silicones, preservatives, and fragrance), it could potentially lead to skin sensitivity, allergic reactions, rashes, and granuloma, as they’re deposited inside of the skin, inside of the wound; not on top of uninjured skin.

What Classifies as Microneedling Gone Wrong?

If done incorrectly, microneedling risks have higher chances of happening and some microneedling side effects are more prominent than they should be. However, some side effects are a part of the normal healing process. Redness and tenderness are to be expected – up to a certain point.

You need to differentiate between microneedling side effects and microneedling gone wrong. Here’s a quick list to help you identify symptoms.

What’s normal and to be expected:

  • Redness
  • Tenderness
  • Irritation
  • Dryness
  • Slight inflammation
  • Slight swelling
  • Slight bruising

What’s not normal and is a cause for concern:

  • Redness and bruising that isn’t going away
  • Prolonged inflammation
  • Your skin is painful to touch
  • Any signs of infection
  • Any signs of allergic reactions
  • Emerging discoloration

How to Avoid Microneedling Gone Wrong

Microneedling treatment is considered safe and even one of the least invasive skin treatments, especially considering its many benefits.

But as with every other skincare procedure, there are some microneedling risks and microneedling side effects. The risks can easily be avoided if the treatment is done properly. Otherwise, there’s a possibility of microneedling gone wrong.

So, what can you do to ensure safe and successful microneedling treatment?

When booking in a salon, make sure you are booking with a licensed and experienced professional that has undergone safety training.

When doing it at home, make sure everything is sterile and you are being gentle. You might not see the difference immediately after the treatment, but it’s better not to overdo it than to regret doing too much.

Main Takeaways

In theory, anyone’s skin can react to any treatment or product. It pretty much seems like it’s dependent on luck. There will always be some bad microneedling experiences, rare cases that are out of the expected norm. It seems like a gamble. But being armed with as much knowledge as possible can help.
