Derma Roller FAQ


What is a Derma Roller?

A Derma Roller is a small hand held device that is mainly used for Collagen Induction Therapy (CIT). As you roll it onto your skin, it triggers its regeneration by signling your body to naturally produce new collagen and elastin, the proteins that make up most of the dermis.

A Skin Roller can be used for a variety of skin problems, including:

  • Alopecia (Hair Loss / Hair Thinning)
  • Wrinkles
  • Scars (including acne scars)
  • Skin Discoloration / Hyper-Pigmentation / Uneven skin tone
  • Cellulite, Stretch Marks
  • Large/Open pores
  • Loose / Sagging skin

For more information see What is Skin Needling

Could using a derma-roller damage my skin?

No. Because the micro-needles in the roller are so tiny, they are able to penetrate the top layer of the skin without damaging it. They create a tiny wound in the skin, but you cannot see or feel it as the damage is on a minute scale. After rolling the pores remain open for about an hour, allowing any creams and lotions applied to be far better absorbed in the skin.

What are the risks of using a generic roller?

The build quality and materials used, type of needles and strelization method - all determine the quality of a derma roller. Cheap generic Derma (Skin) Rollers that are sold by anonymous companies are often of very low quality, and introduce the risk of unnecessary pain at best, and infection and scarring at worst.

Where and when should the roller not be used?

The Derma Roller should NOT be used on pustular acne lesions, active herpes outbreaks, or any other acute infection or inflammation of the skin, and is not recommended for those with the following:

  • Blood clotting problems
  • Poor healing
  • Skin Malignacies
  • Rosacea
  • Eczema
  • Psoriasis
  • Severe solar keratosis
  • Raised moles/warts
  • Open cuts
If you are in doubt of your skin condition do not hesitate to consult your MD. Do not use it on children or animals! Keep it out of the reach of children.


How is the rolling done?

With your free hand pulling the skin, place the roller on the skin and roll firmly with a constant movement. Roll 4 times horizontally, vertically and diagonally, each time lifting the roller and then placing it again, to decrease the chance that you will hit the same place twice.

See our Complete Rolling Instructions for mode details.

Is the treatment painful?

With a 0.25mm roller you will experience nothing more than a slight tingling. The 0.5mm roller is also very tolerable by most people and feels like shaving. As for the 1.0mm and 1.5mm lengths, it is recommended to numb the skin first using a topical anesthetic such as Emla or simply an ice pack.

What is the downtime or side-effects of using the dermaroller?

The average downtime is only 1-2 hours. We recommend rolling 1-2 hours before bedtime, this way, there will be no visible redness on your skin the next day when you wake up.

With hard-pressure rolling, you may experience redness or some tiny red dots inside the skin. From a distance they just appear like rosy cheeks, and they are usually gone within a day.

How long before I see results?

Since Skin Needling affects the deep layers of the skin, results are not instant. Our skin renews itself approximately every 40 days, so this is the minimum time it takes for initial results. However, with each treatment, your skin will continue to improve and usually after 3 months you will start seeing significant and dramatic results.

Note that in the case of very deep stretch marks or scars it may take several months for final results.

How often should I roll?

The rolling frequency mainly depends on the needle length being used. The recommended intervals are:

  • 0.25mm - May be used daily.
  • 0.5mm - 2-3 times weekly for a period of 3 months, then once every 1-2 weeks for maintenance.
  • 1.0mm - Once a week.
  • 1.5mm - Once every 3-4 weeks.

Note that in the case of very deep stretch marks or scars final it may take up to a year for final results.

How much pressure should I apply?

When rolling, considerable pressure should be applied in order for the needles to penetrate fully. We advise our customers to begin by applying minimal pressure, then gradually increase the pressure as they feel more comfortable with it.

Do not worry too much about applying too much pressure, as the needles cannot be pushed deeper in the skin than their own length.

Do I need to use any after-care products?

The redness you get immediately after rolling is the normal reaction of the body to the treatment, and therefore should not be conflicted by any anti-inflammatory topicals.

On the other hand, since the pores are now open, it is the ideal time to apply any cosmetic products that you wish to be absorbed better into your skin. Note, however, that not every cosmetic product is suitable for derma rolling. For example, products containing preservatives and/or acidic substances aimed at peeling the external layer of the skin should be avoided.

Supplemental medications designed for use with a derma roller are available in our store (See our Skin-care products section).

What is a numbing cream? Do I need to apply it before I roll?

A numbing cream is a topical anesthetic preparation applied on the skin to reduce/eliminate the feeling of pain during the rolling procedure. Whether you need it or not depends on your own tolerance for pain and the amount of pressure you use when rolling.

Most customers report that with needles up to 1.0mm they feel they do not need to use a numbing cream.

How long a derma roller will last?

The average lifespan of a roller is 6 months. However, it greatly depends on how often you actually use it. You know it's time to replace your roller when once you feel that the needles are not as sharp as they used to be, making it less efficient.

Why does the DR.Roller package say 'Single-Use device'?

This statement is a requirement of KFDA (The Korean FDA), since Dr.Roller is manufactured in South Korea. But the truth is that as long as the roller is not shared among different people, it may be safely re-used for a period of up to 6 months or until the needles become dull, as long as it's disinfected properly. The disinfection procedure is as simple as washing the roller in warm water and then soaking it in 70% strength alcohol for several minutes. Thousands of people around the world use derma rollers in their own home and the fact is that there has never been one reported case of disinfection resulting from using a roller.

How do I clean my roller?

Rinse the roller under running hot water before and after each use. After rolling and washing the roller, soak it in SEPTOL or isopropyl alcohol for about 5-10 minutes, then leave it to air dry for additional 10 minutes before putting it back into its container.
