FAQ Microneedle

micro needle roller


Q. What is micro-needle roller?
A. A micro needle roller is a small hand held device. The main part of it is a drum studded with tiny ultra-sharp needles. The  most common material used for needles is stainless medical grade steel.  The needles can be also covered with titanium vapor, that gives the needles additional strength. Titanium vapor coated needles have golden look.

Q. Does micro needle roller work for everyone?


A. As with many skin care products, the microneedle roller does not work for everyone. If you do not feel comfortable dealing with needles, even tiny ones, – than you’d better look for another product. The needling may be uncomfortable for you are sensitive to a pain – just like waxing.
Also you should take into consideration the necessity of precautions after needling to avoid possible inflammation.

Q. How does the roller work? Is there any studies that prove its effectiveness?


A. The roller works in two ways. First, it punctures the skin and the needle reaches a dermal level where collagen matrix is located. As the needle punctures the skin, it causes a micro-damage which in turn triggers so called “wound response” – the growth of new tissue. The same principle is used for RF and IPLlaser rejuvenation, Retinoid treatments. It is commonly known as “CIT” – collagen induction therapy

The other application of  Microneedle roller is so called “TDD” – transepidermal drug delivery. The studies have shown that during usual cream application such particle as liposome can only penetrate (through the stratum corneum)  0.3% of total count, when using a micro needle roller this number increases up to 40 times.

Q. What is the difference between titanium and stainless steel needles?


A. Stainless steel needles are made of medical grade SUS-304 steel (the same grade of steel used for manufacturing of hypodermic needles). The thickness of the wire, used for the needles is 0.20mm in diameter. Titanium needles are made of medical grade SUS-304 steel covered with titanium vapor – the composition widely used in implant surgery. It makes the steel stronger but at the same time the wire becomes thicker up to 0.30mm. The punctures made by titanium needles are larger and more visible.

The span life of titanium needles is 6 month VS 3 months for stainless steel.


Q. What needle’s size is the right size for me?


A. Due to the fact that different parts of the body have different skin thickness the needle lengths should be chosen accordingly.

 Areas with different epidermis thickness

Roller size

Around the eye area, lips


Neck, decollete, wrists




Cheeks, chin – fair skin


Cheeks, chin


Arms, abdomen


Thighs, scalp


Thighs, scalp, scar tissues


Scar tissues


For CIT (Collagen Induction Therapy) the needle needs to penetrate 0.5mm deep into dermis. Considering that the top layer of the skin has a thickness of 0.3-0.8mm (on a face) it gives you 1.00mm -1.50mm roller to work with. If you have fair, sensitive skin – downgrade it one size.


Q. Is the roller one time use only?



A. It is recommended to use micro needle roller as a single use device if you are a professional treating clients due to sanitary requirements.

For home use (individual) it is acceptable to use it few times, until the needles will wear out.
The span life of titanium covered needles is 6 month vs. 3 months for stainless steel ones, providing the roller was not dropped, dragged, haven’t been left sitting on hard surface, needles didn’t catch hair or clothes when rolling. It also depends on a way you roll.

You will feel that it is time to get a new roller if it starts to “pull”  the skin.


Q.  How to sterilize my roller?


A. The roller comes pre-sterilized in a sealed bag. The sanitation directions are included in the manual: you can use denture tablets, alcohol or high temperature (boiling water).

Sanitation – You may use denture tablets (in water) to clean the roller. Denture tables are enzyme cleansers and enzymes take off fat as well as reduce bacteria. While not as effective, you may also use alcohol (isopropyl). Consult a pharmacist for the best advice for a sterilization solution. Fill the small saucer or tray with sterilization solution place soft cloth pad at the bottom and roll the roller into the pad with medium pressure. Leave the roller in the cleaning solution for about 15 minutes – ensure that the roller drum is constantly wet with the cleaning solution. Do not leave immersed in alcohol for a long time, although PE-500 polymer of the drum is chemical resistance, the long exposure may cause the polymer to swell.


Make sure you rinse the roller after sterilization and put it into the storage dry. Although the needles are made of SUS 304 steel (the same used for hypodermic needles) it is stain-less, not stain-proof and if stored moist in enclosed environment it may be prone to corrosion. The best way is to dry it with blow-dryer or leave it to dry completely in open air.

This model can be also sterilized under high temperature 130C (266F).


Q.  How often to use the roller?


A. The roller with short needles (0.20-0.30 mm) that are used for product penetration may be used daily.
The roller with middle lengths needles 0.50-1.00mm may be used once a week  for a few weeks. After that your  skin would need a rest.
The roller with long needles over 1.00mm may be used once in 3-4 weeks.


Q.  How to roll?



A. Divide your face mentally on small squares about 1 square inch each. Choose a correct size of the roller. Do not use needles longer than necessary! There is no need to inflict more pain and take an additional risk.
Roll each of 4 axis’ about 10 times. Roll slow, applying the little pressure to make sure the needles penetrate the skin. Do not roll fast! Do not lift the roller from the skin in a middle of the motion.


Q. When do I see the results?


A. Normally you will notice the difference after 2-3 weekly treatments. If you use the roller for product penetration you will see results as soon as the active ingredients of your cosmetics start to work.
In addition, even if the shorter needles doesn’t penetrate deep enough to stimulate collagen fibers, they will work in the upper epidermis layer and stimulate natural growth factor and tighten the skin.


Q.  Does the roller help to get rid of broken capillaries?


A. The micro needling will not help do diminish broken capillaries, as it is not supposed to reach deeper than 0.5mm into dermis (that is why it is important to use right size of the roller), but due to the overall improvement and tightening of the skin the treated area may start to look better.

Broken capillaries can be removed by a procedure called thermolysis. During the thermolysis high frequency electricity of IPL flash are applied and coagulate the tissues.

Q.  Does the roller help to reduce cellulite?


A. Microneelding stimulates collagen production only – it doesn’t penetrate deep in hypodermal level, where the problem is located. Collagen and elastin fibers are located in dermis, when hypodermal level (the very bottom layer of the skin) holds enlarged fat cells. Using the roller you will stimulate the collagen “net”  under the skin that supports the top layer and make the skin to look smoother.

The best anti-cellulite procedures are vacuum massage and infra-red wraps as well as 4Khz ultrasound treatment (the latter is available in salons only).


Q. Does the roller help to reduce enlarged pores on the face?


A. The microneedling alone will not reduce enlarged pores. You would need to incorporate some dermabrasion procedure into your skin care (glycolic peeling, diamond or crystal dermabrasion, etc.).
Microneelding stimulates collagen production only – it doesn’t abrade the skin. Collagen and elastin fibers are located in dermis, when epidermis (the top layer of the skin) is responsible for enlarged pores. Using the roller you will stimulate the collagen “net”  under the skin that supports the top layer and makes it look smoother.

With the use of nutrient serums when rolling, the new cells in epidermis will start to replace the old ones faster. Together with removing the top layer of the skin with microdermabrasion procedures you will accelerate the restoration process.


Q.  Does the roller will help to reduce hyper pigmentation?


A. The roller will not help with this problem. It affects only collagen fibers that are responsible for skin elasticity. On the contrary – it may cause some transient hyper pigmentation of Type IV and higher skin types. Normally, this pigmentation is temporarily and will go away shortly.


Q. What topical (cosmetics) should I use before, during or after microneedling?


A. If you use short needles for product’s penetration (which by the way provides results in skin tightening and wrinkle reduction as well) you should apply active serums or creams before needling. You can use any of your favorite products, providing they come in airless pump-up bottles that prevents the serum from contamination by bacteria.

Do not use creams in jars, where you scoop them with your finger. Those creams are usually full of bacteria and may cause inflammation of the skin.

For deep rolling (CIT), prepare the skin during few weeks prior to needling applying vitamin C serum. You do not need to apply any product when needling. You may use numbing cream that contain lidocain(novocain). Apply the numbing cream and let it sit for about 5 min. so it will start working. Lidocainenovocaine numbing effect lasts for about 15-20 min.
Wash your face with boiled saline water after the procedure and let it dry.

You may apply moisturizing solution (the best one is that comes in ampoules). Do not touch your face and do not apply any makeup (12 hours).

Q. Are all cosmetics OK to use after DEEP dermarolling when topic numbing cream is used?


A. After deep micro needle rolling the usual practice is to clean the skin with a saline solution (distilled water+salt) and wait until the blood will stop. Apply antibiotic cream as an additional precaution and do not touch your face at least 6 hours.

If you do not roll aggressively and there is no damage to superficial capillaries, you may apply one of  our collagen masks. It is individually packed in sealed container and safe to use (make sure you do not have allergy to its ingredients). You can use any mask of this series, depending on your skin conditions. For dry skin we would recommend Collagen mask with Aloe, for oily skin  – Red Wine or Green Tea mask.


Q. Do you sell any numbing cream?


A. We do not sell any numbing cream, as it is medical product. You can buy it at your local pharmacy.

Q.  I am also after a mask that can be used on the face prior to derma rolling.


A. Applying the mask before rolling doesn’t improve the penetration of the products, because at this point the skin barrier is has its usual state.


Q.  How to choose the right roller to treat scars?


A. The best way would be to ask your dermatologist. As a specialist, he could evaluate your scar, its thickness and give you an advice what size of roller you would need.

If you are not sure about the size, it is recommended to start with 1.50mm roller. Remember, needles longer than you need may cause damage to nerve and vessels.
The needle is supposed to penetrate under the scar tissue to release fibrous bands at dermal and deep dermal subcutaneous plane.

A small hematoma is allowed to be formed, which supports the released scar. Haemostasis is maintained with pressure and ice application on the day. Repeated treatments are required for better cosmetic results. Treatments are done after 3-weeks interval. Care should be taken to avoid the preauricular, temporal and mandibular areas in order to avoid injuries to the facial nerve and major vessels.


Q. What to expect after rolling?


A. Rolling with a micro needle roller that has short needles does not draw blood but you should experience a distinctive swelling and redness in the area. If you use longer needles (1.00- 1.50mm) your may have tiny bleeding where superficial capillary system got reached.

You may experience some small hematomas next day – like red dots or dotted scratch lines. They may turn bluish as the blood will coagulate (bruising). It is very important to roll correctly. Please, remember to take a great care during the treatment.

It would be bet to roll on Friday – the face may have some marks next day. If you do not feel comfortable with the marks on the skin, we would recommend to start with 0.50-0.75 roller.

When rolling with micro needle roller of this size, there is no damage to the capillary system and the face looks normal next day (however skin reaction is very individual). After rolling you may have slight redness. The skin may feel a bit itchy and dried out. The feeling resembles light sunburn. It is normal reaction. Make sure you have a good moisturizer on hand and avoid sun exposure for a few days.
