Question of the week: Will dermal rollers get rid of acne scars?

Chris asks…Does dermal rolling really work to remove acne scars and can you do it at home?

How does dermal rolling/micro needling work?

A dermal roller is one of the devices used in micro-needling which is the process of pricking tiny holes in the skin to stimulate collagen production. The technical name for this is “Percutaneous Collagen Induction Therapy” which is abbreviated as PCI or CIT). It’s been used by dermatologists for the last decade or so as a way to reduce wrinkles and scar tissue without significant side effects.

Basically, the process involves numbing your face and then poking it with fine needles a few millimeters long. These micro perforations trigger increased collagen synthesis. For some conditions it’s supposedly even better than lasers or dermabrasion because those procedures can cause a loss of skin elasticity.

Here’s how it works: Micro needling takes advantage of the skin’s normal response to any kind of inflammatory wound. If you cut your skin, for example, the platelets and neutrophils in your blood release growth factors which increase the production of components of the intercellular matrix of your skin.  With micro needling, you prick the skin with a specially designed device that creates hundreds of micro wounds down in the dermis. These micro wounds cause this superficial inflammatory response which increases fibronectin production which sets up kind of a scaffolding where collagen is deposited. And over time this collagen goes through a conversion process where it naturally tightens up which reduces wrinkles and helps resurface scars. And because these needle holes are so small, there’s little risk of side effects from things like exposure to air or infection. Better still, there’s no post inflammatory hyper pigmentation like there is with some kind of wound healing.

What are the proven benefits of micro needling?

Acne
Chris asked specifically about acne scars and there have been studies which document that it really works. Here’s one example:

One 60 patient study published in the Journal of Dermatological Treatment in April 2014 showed an average 31% reduction in acne scars as measured by silicone replicas of the skin. They concluded “PCI offers a simple and safe modality to improve the appearance of acne scars without risk of dyspigmentation in patients of all skin types.” http://informahealthcare.com/doi/abs/10.3109/09546634.2012.742949

Anti-aging

As we already mentioned the procedure boosts collagen so it can reduce wrinkles. And there are even studies which indicate it can help anti-aging ingredients penetrate better. Here’s another study, this one from a 2011 edition of the Journal of Plastic, Reconstructive & Aesthetic Surgery. It’s called “Percutaneous collagen induction–regeneration in place of cicatrisation?” (sick-uh-try-zation.) This particular study involved four groups of rats:

  • Group 1 the control group received no treatment
  • Group 2 received topical vitamin treatment Vitamin A retinyl palmitate 1% and Vitamin C ascorbyl tetra-isopalmitate 10%
  • Group 3 received needling only.
  • Group 4 received needling plus vitamin treatment

After treatment they looked for changes in epidermal thickness, expression of the genes that control collagen production, increase in collagen, fibronectin, glycosaminoglycans (GAGs) and some related growth factors. The results were interesting – across all these parameters they saw a trend that the vitamin treatment alone showed a small improvement, needling showed a bigger improvement, but the combination showed an even BIGGER improvement.

Stretch marks
And finally here’s a study from a 2010 issue of Plastic & Reconstructive Surgery showing PCI even helps reduce stretch marks.

22 women with Striae Distensae were micro needled for a single 30 minute session. They were then assessed after 6 months and the needled area showed “improved skin texture, skin tightening, dermal neovascularization, and no change of pigmentation.” They even took biopsies which showed an increase of collagen I and elastin.

Can you needle yourself? The importance of needle size

Can you micro needle yourself? Actually, it’s not as simple as that. Depending on what benefit you’re trying to achieve, self-micro needling may not be such a good idea. Part of this concern is that not all dermal rollers are the same. The first thing to understand is the importance of needle size.

Short needles (0.1 to 0.3mm)
These are used for cosmetic needling only. They can improve penetration of active ingredients but will NOT stimulate collagen production or affect scars. They require no special skin preparation other than proper cleansing and, as I said, the use of anti-aging creams or lotions.

You can use these at home but they won’t boost collagen or treat scars and if you’re not using this type of roller with a truly functional anti-aging ingredient, you won’t see any improvement at all.

Medium length needles (1.0- 2.0 mm)
These are used for “medical needling.” These needles WILL activate collagen synthesis as long as they puncture enough capillaries. This is what is called a “petechial hemorrhage” and it’s required to trigger the anti-inflammatory response that we talked about earlier. 1.5mm needles will even work on some shallow acne scars. When this kind of needle is used properly you’ll have tiny red-purple blood dots all over your face. And, since you’re wounding the skin to a great extent, these needles require a topical anesthetic. These needles are sold for use at home but if done properly they are painful to use and remember – you need to bleed.

Long needles (3.0mm)
These are used for “surgical needling” and they penetrate deep enough to work on deep scar tissue. They MUST be used by a physician or trained medical personnel and may even require general anesthesia. They produce a LOT of blood. Obviously you can’t do this yourself.

Device quality and the importance of proper application

There are differences between the “at home” versions and the professional versions. The “professional” needles, like the Environ® Medical Roll-CIT, are made from surgical grade stainless steel and they are gamma sterilized so you know they are safe and clean. Products like this have some kind of disclaimer like “This product is highly specialised, for use by medical doctors and trained medical staff only. Professional training at one of Environ’s institutes is therefore required before this product may be used in treatments.”

Now should you decide that you want to try this for yourself, there are 3 dangers of DIY dermal rolling that you should be aware of:

1. Beware of misinformation
Needle size is critical. It looks like some companies who make these rollers are very clear about the difference between the professional models for medical use and the home models for cosmetic use. But other companies blur the difference and imply that the home model will provide all the benefits of the medical treatment model. Here are two examples of dermal rollers you can buy for use at home:

The Scientia Dermal Roller
Dermal Roller Systems (http://www.dermarollersystem.com) This is one the featured on Rachael Ray.

Their websites provide usage instructions but neither say anything about the petechial hemorrhages and the Dermal Roller System doesn’t even tell you to use a topical anesthetic gel!

2. Practice good hygiene
Another important point to consider is hygiene – whether you’re doing it at home or even more so if you’re having it done in a salon. I saw an article “Salon workers often skip the sterilizing process in between sessions and continue using rollers which can become bloodied after one session. This can expose clients to risks such as HIV and hepatitis.” http://www.truthinaging.com/review/beware-of-micro-needling. So this is nothing to screw around with.

3. Watch out for skin damage
Finally, there are those who say that rolling needles can tear the skin and that you should use stamps and pens which are provide “Vertical PCI.” These are supposedly superior because they can apply controlled pressure rather than requiring you to judge how hard to push the roller. They also poke holes perpendicular to the skin to they don’t tear as much. Also, needle cartridges are disposable and so are safer and more sanitary.

The Beauty Brains bottom line

Does micro needling really work? The preponderance of data indicates that when the correct needles are used properly it IS effective for reducing scars, wrinkles and stretch marks and it can help with anti-aging treatments. According to the scientific literature, the procedure has to induce some bleeding to be effective.

On the other hand, you have companies selling the do-it-yourself versions which claim they only cause a little transitory reddening of skin. That sounds suspiciously like “cosmetic needling” which is not intense enough to trigger collagen production and heal scars.

So if you want to give your skin care regimen a boost these at home devices seem like they can help ingredients penetrate but if you have serious scars that you want to remove, you’ll more likely to have the treatment done professionally.

    Great information guys. Enjoyed learning more about this.

  • Elizabeth S. August 26, 2014, 3:30 pm

    Thanks for all of the information. Any opinions on the Rodan + Fields AMP MD roller?

    • Randy Schueller August 26, 2014, 4:31 pm

      I can’t find any detailed specification on the R+F roller but my guess is that it falls into the “cosmetic needling” category because it’s designed to be used with their retinol serum. Since the data show that derma rollers can increase efficacy of Vitamin A compounds, the product could perform as promised. The real question is does it work better than other, cheaper, products.

  • Vicki August 27, 2014, 7:45 am

    Thank you for the all the great information. I’m actually in the process of getting certified for micro needling from Dr. Lance Setterfield. I can’t stress enough how I would not recommend performing needling at home. So many product ingredients need to be avoided in order to prevent irritation and granulomas and even track marks.

    • Chris August 28, 2014, 2:22 pm

      Yeah, that’s exactly what I’m concerned about. You would probably be restricted to a few products, and we all know how much we love our massive collections of cosmetics.

    I have started using a tattoo needle in combination with an application of a copper peptide solution on a few bumps on my face. Last month, I had excellent results treating a spot that was identified as sebaceous hyperplasia by two dermatologists that were both unsuccessful in getting rid of it through various methods. Another dermatologist told me it would be too difficult to treat. As a result, I lived with this spot for four years. Then, after some online research, I decided to try the copper peptide solution with the needle…. and I got rid of it in two weeks! I am simply amazed and am very pleased with the results. I am now working on spot #2. It’s in the “ugly” stage right now but that’s part of the process.

    Having said that, I’ve looked at the needle rollers before and they scare the bejesus out of me! If I went that route, I’d definitely let a doctor handle that procedure.

    Good information here on this topic. Thanks, Beauty Brains, for always being a trusted source!

    P.S. I tried searching your site for more information on copper peptides using the search box on the home page today but it will not allow me to enter information. As soon as I start typing, the page changes for some reason. Just an FYI.

      That was the only results of the BB website when I searched Copper Peptides.

      • Randy Schueller August 27, 2014, 2:43 pm

        I think we may have had one or two other posts on the subject but they were lost in the Great Data Crash of 2013. I’ll add it to the list of future topics.

    • Randy Schueller August 27, 2014, 2:44 pm

      Thanks for the comment Karen. Are you still having trouble with the search function? I tried it and it works fine. Could be a browser issue?

      • Karen September 9, 2014, 11:31 am

        Yep; that’s what the problem was. I switched browsers and all is well now. Thanks, Randy!

        I really, really, REALLY hope you blog soon on copper peptides. I continue to have great success with my needling + CP strategy that exceeds results from dermatologists. It’s crazy good!

        • Randy Schueller September 9, 2014, 3:18 pm

          Karen: We’re looking into peptides are part of the research we’re doing for a potential book on anti-aging. (So no blog post on peptides in the short term – sorry!)

          • Karen September 11, 2014, 7:44 pm

            That’s terrific! Then I look forward to your new book! Happy research. :)

  • Tamira Hamilton August 30, 2014, 2:29 pm

    Yikes…needles scare me. I would like to see video to better understand this. I am just for much less invasive solutions but to each their own ;-)

  • Ms. George September 19, 2014, 11:29 pm

    I don’t think that this is for me, unless needling my skin meant done professionally. This is a very informative post. I have learned and enjoyed a lot reading this.
