When choosing your DermaRoller, what needle size is best for you?

The Scientia Derma Roller is available in a choice of different needle sizes, so you should choose the needle size which best suits the condition or body part you are trying to treat.

Derma Roller Needle sizes for home use include 0.5mm, 1mm (1.0mm), 1.5mm and for professional use, we have 2mm (2.0mm) and 2.5mm rollers.  We also have 3 line rollers (made narrow to reach harder to treat areas like around the nose) in 1.0mm and 1.5mm sizes.

So what needle size is best for me?

Which needle size for stretch marks?

We recommend 1.0mm for light stretch marks and 1.5mm for deep stretch marks, you would need to decide which would best suit your needs.

The correct needle size for acne scars or other facial scars?

We recommend 0.5mm for light acne scarring, mild chicken pox scars or ice pick scars, or simply regular anti ageing treatments.  A 1.0mm roller is more suitable for deep acne scarring, surgery scars, ice pick or chicken pox scars, and 1.5mm Derma Rollers are for very deep scarring.   A Derma Roller 1.5mm is the maximum we would recommend for use on the face (unless as part of a professional treatment), but your body is less sensitive to treatment,  so you should decide which would best suit your needs.

You may also wish to choose the 3 line roller as it is better suited to use on certain parts of your face (such as around the nose), but it is not always necessary as our regular roller may suit you.

What size of DermaRoller for hair loss?

For thinning hair or greying hair, the 0.5mm Derma Roller is ideal, with 1mm rollers more suitable for more extensive hair loss.

What about for Cellulite?

The best needle size for cellulite is 1mm or 1.5mm depending on how severe the case is.

Is the right Derma Roller needle length the only factor?

No.  We also recommend the use of our vitamin rich treatment cream and Scientia Nutrition MultiVitamins as they have all the ingredients needed to support the use of the Scientia Derma Roller, and we find it can speed up results by giving your skin the building blocks it needs to generate new collagen and elastin –  the materials which give your skin its elasticity and smooth texture.

What about sterilizing your Derma Roller?

To sterilize your Derma Roller, we recommend the same product used to sterilize baby’s bottles (sterilisation liquid or sterilising fluid) available from your local pharmacy or supermarket.

Dermaroller Instructions

There are two methods of use for the Scientia Derma Roller. One version involves the use of Topicaine Gel to numb the area, followed by more aggressive use of the Scientia Derma Roller once per week. The second alternative, involves using the device with slight pressure up to 5 times per week (Instructions are only a guide and you should always assess your skin before and after each session). Using the device gently gives a tickling feeling and is not painful – although your face is more sensitive to it than your body.

Neither method should draw blood. You may find a temporary reddening of the skin for an hour or so after treatment and it can give a sensation similar to mild sunburn. We recommend the use of sunscreen / sunblock after use.

Establish a Sterile Environment:

Please ensure that you wash your hands (and the area to be treated) thoroughly prior to using the Derma Roller. Dry with a clean towel. Using disinfectant, clean your treatment table and lay out the following items: Scientia Derma Roller, tube of Topicaine Gel, (if used), antibacterial cream, a bowl of iced water with a washcloth in it, a clean towel, some paper towels, a glass containing some disinfectant, a good quality face / body moisturiser and a timer.

Face and Body Treatment:

If using the Scientia Derma Roller on your face, do not use on the eyelids or lips. Wipe off the excess Topicaine Gel (if used) with a paper towel. Roll the Scientia Derma Roller over the area in question several times in different directions. 4 Rolls vertically, horizontally and each diagonal is more than enough to stimulate collagen formation in the skin. Do not press too hard, as this is not necessary for excellent results.

Derma Roller Instructions

If you use the numbing gel and are more vigorous with the Scientia Derma Roller, you may experience a reddening and rawness of the skin for up to a couple of days after use. If you are more gentle, but use the device regularly, the same results can be achieved with much less trauma to your skin. Reddening only lasts for a few minutes.

For hair loss, thinning hair or grey hair:

Each morning / night, after showering and washing your scalp, dry well with a clean towel. Roll the Scientia Derma Roller over the scalp in one direction (and not back and forth). Apply 1ml of 5% Minoxidil (which should be available from your local Pharmacy) to balding areas and massage into the scalp thoroughly. If you notice the scalp flaking after a few days, simply rub the dead skin away whilst shampooing your hair. Treat no more than once per day, 5 times per week.

Skin Care After Use of the Scientia Derma Roller

After use, wash the treated area with cold water, dry the skin gently and apply cream. If you have used the numbing gel, use the antibacterial cream first, shortly followed by a quality moisturiser. If used gently, without the numbing gel, simply go straight to the quality moisturiser – preferably one containing Vitamin C and E. Using the Scientia Derma Roller greatly increases the absorption of these nutrients. Visit our online ordering page to buy cream online.

Instructions: Care of your Scientia Derma Roller:

When you have finished using the device, rinse the roller under hot running water. If you have used the roller with numbing cream, stand head first in the half full glass of disinfectant for approximately 30 minutes to 1 hour (but no longer). If you only used the roller gently, you need only disinfect the device on a weekly basis. Shake off the excess liquid and stand on a clean towel to dry. Please do not put the device away while it is still wet. When it is completely dry, replace the plastic cap and store the roller in the plastic tube provided. Please try to keep the case clean and store somewhere safe so that the device cannot be damaged between uses.
