Let me introduce you to microneedling along with all the benefits and what you can expect from microneedling.   

Facts About Microneedling

What Does Microneedling Do?

  • Improves fine lines and wrinkles
  • Prevents dark spot formation
  • Reduces hyperpigmentation
  • Increases collagen in the skin
  • Reduces Acne Scars
  • Reduces the appearance of stretch marks
  • Increases the rate of skin cell turnover

When your skin is facing several problems at the same time such as acne scars, fine lines, dark spots, and hyperpigmentation, microneedling is one of the most effective treatments to resolve most of them.

What Is Microneedling?

Microneedling is also known as collagen induction therapy. It's based on the 1950's cosmetic treatment called mesotherapy. Microneedling is a non-invasive procedure where several sterile micro needles are pressed into the skin. These pricks create tiny micro holes that trigger the skin's repair system to create new collagen and elastin fibers. Topical skincare applied right afterwards is also absorbed better.

Benefits of Microneedling

  • Immediate skin-plumping effect 
  • Lasting results
  • Almost no risk of skin trauma
  • Rapid recovery 
  • Suitable for nearly all skin tones and types 

According to research, microneedling causes a healing response in the skin that improves different kinds of scarring including acne scars & can help reverse skin damage caused by the sun. This is because microneedling helps to renew the skin and can stimulate the formation of collagen which is the foundation of skin.

Who Can Try Microneedling?

     Microneedling is suitable for all skin tones and of all ages, but it's best to wait if you are 16 and older. 


    Microneedling can also be done on other areas including areas around the mouth, neck, body, arms, and legs. 

    Who's Not Suitable For Microneedling?

    Do not try microneedling if you have

    • Active Rashes or infections
    • Open Wounds
    • Eczema or Rosacea
    • Pregnant
    • Taking certain medications such as Isotretinoin
    • Prone to keloid scars

    People who have a lot of active acne, active rashes, active infection, open wounds or cuts on the skin and keloid scarring (hypertrophic scars/poor wound healing), or are taking medication like isotretinoin are not suitable for microneedling.   It may take a longer time to recover for people who have poor self-healing ability.


      How Does Microneedling Work? 

       To understand how microneedling works, I’ll explain more about the different layers of skin and skin functions.

      Layers Of The Skin

      Skin is divided into two layers, the Epidermis and Dermis.

      microneedling drawing epidermis level 0.5mm

      The outermost part of the epidermis is the Stratum Corneum, whom's job is to protect bacteria out and to keep our tissue fluids from evaporating out. 

      The Dermis Layer is the tissue below the Epidermis Layer. The Dermis Layer is the last part of the skin and can reach a depth of 4mm.

      The Dermis layer is where there arecollagen and elastin fibers are and the main source of skin elasticity. Deeper in the dermis is the subcutaneous layer which has nerves and nerve endings,blood vessels, lymphatic vessels, and some muscle. 

      Cosmetic ingredients are can have trouble being absorbed by the skin; because it isvery difficult to penetrate ingredients through the uppermost layer of skin.

      Most ingredients will beblocked by the skin barrier since the barrier is working hard to block out bacteria. A smaller percentage of the ingredients are able to be absorbed by the skin. Our microneedling tool solves this problem as it creates micro channels so skincare ingredients can effectively absorb into the skin.  Don't be alarmed, these micro channels close up within a couple hours and aren't visible to the naked eye. 

      Main Benefits Of Microneedling

      Stimulates Collagen Production To Reduce Acne Scars

      Collagen is the most abundant protein found in our skin. As we get older, our production of collagen reduces. Thereduction of collagen leads to more a higher chance of scars forming, and increase in fine lines and less plump appearing skin.  Scars that are formed are because of areas of damaged collagen.

      Microneedling is also calledcollagen induction therapy. The needle pricks signal our skin to cure these micro injuries on the skin. Once the skin receives the signal, it recreates collagen to fill in the microchannel, and the surrounding area get repaired too!  As a result, the uneven parts of our skin are filled withnewly produced collagen, and it pushes out an old layer of skin to improve acne scars, dark marks, and fine lines over time.

      Creating Microchannels for Skincare Absorption

      The Banish microneedles’ length is 0.5 mm. During the treatment, the microneedlescreating micro wounds on our skin. Since the holes don't reach the dermis layer, which contains nerves and blood vessels, Banish microneedling technology won't cause pain or bleeding.

      The microchannels allow your skin to absorb more of your skincare products applied afterward, which improves the efficacy of your products and absorption percentage. It's important to avoid applying products that are too strong like acne medications,  avoid exfoliating products, or products with a lot of preservatives right after microneedling.  

      Does Microneedling work on Hyperpigmentation? 

      Microneedling has been shown to reduce hyperpigmentation.   Hyperpigmentation is the darkening of a part of the skin caused byexcessive production of melanin. Many factors may lead to hyperpigmentation, but most commonly it happens from the inflammation after acne. Other factors include exposure to sunlight, allergic reaction, hormonal imbalance.

      Through microneedling,small injuries or 'micro wounds' are made on the skin. During the healing process,  the old layers of damaged skin will peel off and the fresh new layers of skin will be pushed to the surface.  

      This study shows that microneedling can improve both acne scarring and hyperpigmentation at the same time. The patients got general “lightening” of dark spots and improvement of scarring. The experiment got a 79% satisfaction rate, indicating the expected results and safety of the microneedling treatment.

      Safety Of Microneedling


      Is at-home Microneedling safe? 

      When you are using a microneedling tool from a reliable source along with proper handling and cleaning, it is considered safe.  Tools that are 1mm in length and longer could cause more risks versus the shorter ones. Longer sizes should be used in a professional setting only.

      There are several different sizes of microneedles. Each length has a different function. Longer needles (1 mm or longer) are usually used in professional microneedling treatments since they are more dangerous and can reach the deeper levels of skin that contain nerves and blood vessels so it's best for a professional to use those tools. 

      Banish uses a 0.5 mm microneedle stamp, which won't reach the dermis layer or cause unnecessary trauma when used as directed. This is the minimum length needed to stimulate collagen formation. 


      The material that Banish is using is 24k gold plated titanium which is completely safe after sterilization or sanitizing. 

      Gold is chemically unreactive, so it won’t easily react with the vapor in the air or the sweat on the skin.

      Titanium is as strong as steel but much lighter weight. It does not corrode or tarnish, and it's non-allergenic.

      What you need to know before Microneedling

      Although Banish uses the highest quality and safest materials, all microneedle tools should be sanitized or sterilized before use.  For home use, soak the bristles in 70% isopropyl alcohol to kill bacteria on the bristles. The skin should be thoroughly washed and you could also use a rubbing alcohol pad to sanitize skin too.  Hands should also be thoroughly washed. 


      Does Microneedling Damage Skin?

      Since it’s all based on the reversible nature of human skin, with the proper use, microneedling does not cause long term damage to the skin. The microchannels created to heal and close up within a couple of hours. 

      When do the Microchannels close up?

      According toresearchers, the microchannels created by 0.5 mm microneedles have been reported to  close within 18 hours. Microchannelsclose in several hours depending on the length of needles.

      When can we see results?

      It usually takes 4-6 weeks to see minor results. For bigger difference on acne scars or fine lines, it can take up to 3 months and results will vary from person to person. Keep in mind that everyone has a different skin healing time and different degrees of scars. If you want to see the progress of microneedling, check our consumers’ self submitted before-and-after after trying microneedling with the Banisher. 

      Are The Results Permanent?

      The short answer is yes the results will be permanent unlike fillers, but you have to take into factor that skin is always growing and changing as we age.  No skin enhancement procedure is truly permanent.  Similar to exercising and building muscle, our muscle mass will decline as we naturally age. Even if you reach your desired results the natural aging process would make it not permanent. 

      At-home Microneedling VS. Professional Microneedling

      Professional Microneedling

      • Needles are longer 
      • Needs professionals to operate
      • Costs more
      • Quicker effectivess and Better benefits especially on deeper scarring
      • Longer downtime and side effects

      At-home microneedling

      • Suitable for a larger range of people
      • Faster recovery because of shorter needles
      • Convenient at home
      • Less than $100 and can do up to 10 treatments
      • No bleeding and only causes a temporary redness
      • Good for maintenance and sustaining results but less effective results

      In comparison, both treatments have pros and cons. At-home microneedling is more cost-effective, available, and convenient, while professional may provide faster and better results for deep scarring or deeper fine lines. 

      How Much Does Microneedling Cost?

      In office microneedling may cost anywhere from $200 to $700 per session in the U.S. and it depends on the area. Although the number of sessions can vary, most people need three to six sessions for optimal results. With this in mind, you may spend anywhere from $600 to $4,200 overall. 

      Factors that determine the exact cost of microneedling sessions include:

      • Your provider
      • Your location/area 
      • The office that is providing the treatment
      • Length of treatment
      • How many follow-up treatments you need
      • How well your skin responds to treatment

      A usual treatment course of microneedling consists of 3 to 5 sessions spaced at least 4 weeks apart - with results being seen in 3 months.

      Some may decide to treat their acne scars with microneedling at home. If you go this route, use a tool that is safe for home use like the Banisher 2.0, replace it after 10 uses or every 3 months, and don't ever share your microneedle tool. 


      Side Effects of Microneedling

      Several  scientific clinical trials have done and the results proved that microneedling is a  safe and effective therapeutic option for the treatment of scars.

      Here are some possible side effects after microneedling:


      Bleeding is common after getting microneedling done in office, especially if long needles were applied for the treatment. In most circumstances, bleeding is not an issue because it is caused by needles reaching blood vessels in our skin which should only occur in a professional setting.  


      In order to eliminate this possibility, sanitize your skin and microneedle tool thoroughly before using. Don't use your microneedle tool over open wounds, acne, rashes or other skin conditions.  Do not share your tool with anyone and replace it regularly and there's pretty much little to no risk.


      A little bit of pain is possible after microneedling, but most people do not feel any pain at all.  Itching can be common because your skin is healing the microchannels created on your skin and the healing process can feel like an itchy sensation. The itching feeling should go away after a day.

      Again, side effects are not common after microneedling. If the needles are 1mm or longer, do not do the treatment by yourself and ask professionals to help. With proper sanitation and standard products and steps, the possibility of experiencing these side effects is less than 0.1%.   

      How to use a Microneedling tool?

      Use the Banisher microneedling tool  once a week. Do not do a microneedling session too often since it takes time for skin to heal and recover. Consistency brings better results.  If skin is sensitive, reduce frequency to once every 2 weeks. 

       (check our video)

      1. Sanitize the Banisher using alcohol and let the bristles touch the alcohol for at least 5 minutes. Clean skin and hands thoroughly. 
      2. Let the Banisher air dry for 2 to 3 minutes
      3. Use light and even pressure, press the Banisher 4 to 5 times on the areas you want to treat, making sure to avoid using on any active acne or rashes.
      4. Rotate the Banisher about 90 degrees whenever you lift it up,  and press down again.  Do not drag or twist the Banisher when it's on the skin. 
      5. Sanitize the Banisher again and place the protective cap back on.


      What Skincare Should I Apply After microneedling?

      Vitamin C in the form of L-ascorbic acid is the most popular form of topical applied. 

       Vitamin C (ascorbic acid)

      Vitamin C (ascorbic acid) is an antioxidant that maintains the synthesis of collagen on human skins. In order words, it accelerates skin repair, which can reduce acne scars, and it is a perfect product for anti-aging. The research study shows that vitamin C also helps the photoprotection from UV A&B and inhibit melanogenesis, which may cause hyperpigmentation.

      According to the researchers, using Vitamin C with microneedling had a 63% possibility of leading to smoother skin. Applying Vitamin C after microneedling can amplify the benefits of both of them.

      Banish Oil is a fresh vitamin c serum to apply after microneedling that isn't too strong and it's very hydrating. Its ingredients contain L-ascorbic acid, Vitamin E, aloe vera, rose water, and ferulic acid. It can help the healing process without overly irritating our skin. 

      Apply Moisturizer

       Staying moisturized is also important after microneedling.

      • Apply Moisturizer

      Keeping skin moisturized is important so skin is protected and less prone to irritation as it heals. The best product to help our skin stay moisturized is always a good cream or moisturizer. The Banish Vitamin C crème contains natural ingredients and doesn't leave a heavy or greasy feel. The Banish Oil is also hydrating containing the humectant glycerin. 

      What should you avoid after microneedling?

      Avoid Exposure to the Sun (Sun protection)

      Use sunscreen with a sun protection factor (SPF) value of 30 or more when you are outside. Without sun protection, microneedling may lead to higher PIH (post-inflammatory hyperpigmentation) risk because of UV damage.

      Avoid exfoliating ingredients

      Avoid products with BHA or AHAs and Retinol (Vitamin A), they can be too irritating to apply after microneedling. Give your skin time to recover from microneedling before applying these types of products.

      Avoid Wearing Makeup 

      You should avoid wearing makeup for at least 8 hours after microneedling. Since your skin has open channels - wearing makeup may lead to clogged pores and irritation.  It doesn’t take a long time to heal the skin for most people when using the Banisher 2.0 as instructed. You should be okay to wear makeup the following day. 


      Where to buy a quality microneedling tool?

      banisher 2.0

       Banisher 2.0 (Derma Stamp)

      • 24k Gold Coated Titanium Bristles 
      • Finer and sharper bristles
      • Less irritation 
      • Needles go into the skin at 90 degrees every time
      • Lower risk of injury compared to rolling tools 

      banisher 2.0 versus dermarollers

      The Banisher Roller used the technology of  a dermaroller, the first microneedling product for skincare. The new  Banisher is safer, more convenient, and causes less irritation. It prevents the risk of "Tram track" scarring which may be caused by rolling microneedles back and forth over skin.

      In conclusion, microneedling is an amazing technique to combat acne scars and help with many other skin concerns that pop up. Take a look below to see some customer submitted results from microneedling.
