Choosing the Correct Derma Roller Needle Size

The needles of derma rollers come in varying sizes, from 0.5 mm to 2.5 mm, each targeting a particular type of skin problem. For simple treatments needles that are smaller than 1.0mm are used, while larger ones are used for bigger skin issues. Discover which needle length is best for you and use your derma roller for desired results. 


Derma Roller with 0.5mm needle

If you want to treat hyperpigmentation, UV damage, light wrinkles and light scarring then a derma roller with 0.5 mm needle is the one suitable for you. It also increases the rate of absorption of skincare products leading to better results. Longer needles must be used with care as derma rolling generally leads to dry skin. You can use the 0.5 mm needles 4 to 5 times a week without seeing any unwanted contraindications. Numbing creams are unnecessary as there is only mild pain and blood spotting.            

Some people may face skin irritation and reddening after weekly usage, while others may not. How much your skin reacts to the derma rolling is an indication of how frequently you can use the 0.5mm needle.

The treatment can be repeated as much as 5 times a week


Derma Roller with 1.0mm needle 

When it comes to inducing collagen production, this needle size is more effective than smaller needles. The derma roller equipped with 1.0mm needles can treat wrinkles, scars and stretch marks well, in addition to UV damage and hyperpigmentation. You will get an even complexion and smooth texture of skin by using this sized needle. You can use this needle size freely on the forehead, cheeks and lower neck, but it should be used cautiously around the eyes and behind the ears which are sensitive areas.

Users will have to bear a moderate amount of pain due to the depth of penetration by the needle, which will take up to a week to recover based on how aggressive the procedure was. For those who have sensitive skin or intolerance for pain, numbing cream may be used.

The procedure can be repeated every 3 to 4 weeks


Derma Rollers with 1.5 mm – 2.0mm needles

In order to treat various skin problems not only found on the face but other parts of the body too, these medium sized needles are suitable. They can be used to treat moderate cases of stretch marks, wrinkles and scars in areas such as abdomen, arms, thighs, hands and décolleté areas; however, it should only be done by those with knowledge about derma rolling, or supervised by them. 

Because of the deeper penetration of the 1.5mm and 2.0mm needles, there will be more pain in the process. For easing the pain, an anesthetic is used prior to the treatment.

The procedure can be repeated every 4 to 5 weeks.


Derma Rollers with 2.5mm microneedles 

These should be used with care as they are long needles. The needle of size 2.5mm should be used on areas of thick skin such as the arms, feet, thighs, upper and lower back, butts and the back of the hand, depending on the intensity and how often you do the procedure. 

Because it can reach deep into the dermis it is the suitable size for people who look to treat stretch marks and severe burn scars.

Normally this needle size would present some side-effects after the procedure. Use of anesthetic is needed for the procedure as a caution. The 2.5mm needles would cause light bleeding, reddening, swelling and dryness after the procedure. It would take around 7 to 10 days to recover from the procedure; there should be no other skin procedures during this period.  

The procedure can be repeated every 4 to 5 weeks


Precautions When Using Derma Roller


Choosing the wrong needle size is one of the mistakes people do when performing derma rolling to improve their skin. The following are some other mistakes.


  • Avoid Derma Rolling if you have sore skin, active acne, or any skin disease.
  • If you are taking any medicine consult your doctor prior to the procedure
  • Do not share your personal kit as it could transmit skin diseases
  • Don’t use excessive force when rolling as this could lead to irritation and irregular swelling and prolong the recovery time
  • Avoid applying tanning lotion or make-up right after treatment because derma rolling would create micro channels deep into the dermis.


Results of Derma Rolling

Use the suitably sized derma roller at the right time to effectively treat your skin. You need to take into account that microneedling should be done long term to see results. The operated region would usually look plumb due to the increased blood circulation and growth in the area. This symptom usually goes away after 24 hours, while other symptoms such as dryness and reddening may persist based on the magnitude of the operation.  

After about 3 to 6 operations, new collagen and elastic will gather under the skin, leading to the gradual disappearance of wrinkles, stretch marks and scars. One important thing to realize is that using the wrong needle size could actually make the skin condition worse, prolonging proper treatment.
