FAQ

GENERAL
What is a "derma-roller"?
A "derma (skin) roller" is a hand held tool that is used for collagen induction. When used as directed the micro needles penetrate the top layer of skin without damaging it. This sets in motion the production of collagen and elastin.
For more details see my post: What's a Derma (skin) Roller?.

What is it good for?
In general, microneedling rollers trigger the natural ability of the body to produce Collagen in the skin which thickens it. They are effective against scars (especially ones that are pitted), fine lines and wrinkles, and also to reduce the appearance of stretch marks. With the right cosmetic products, they can also improve the skin tone, clear out blemishes such as sun spots, tighten the pores and even help with hair loss.

Is it safe for home use?
Yes, if you follow the instructions carefully, (see: Is it safe to use a skin roller at home?)

Is this blog related to Dermaroller(TM)?
No. This is a personal blog run by a person who has been using skin rollers for the past year, and decided to share his experience with others, as a hobby.

This blog is not affiliated or related in any way to the derma roller brand called "Genuine Dermaroller(TM)". The term "derma roller" used in this blog is merely a descriptive name for the general princriple of a roller used on the skin (derma=skin), and should not be confused with any specific roller brand.

Just to make things clear, I do not sell anything other than my skin serum, nor do I get any payment for linking to any website that sells skin needling equipment for home use.

How can I get the original Dermaroller(TM)?
You can't. The original Dermaroller(TM) company is now only selling to trained doctors and clinics. However, some other brands that can be bought online are just as good.

How to choose a derma roller brand and the needle length?
There are quite a few brands to choose from, some more high-quality than others. The needle length depends on the body area you're treating and your skin condition.
For detailed information see this article: How to choose a skin (derma) roller.

How does it work exactly?
The theory is that making tiny punctures in the skin triggers the immune system to produce collagen and elastin to heal the skin like it would in the case of real wounds.
However, even the doctor who supposedly invented the (original) Dermaroller(TM) isn't 100% sure why it's working, as you can see in this interview.
Personally, as long as it works, I don't really care much for the reasons.

Where is the best place to buy a roller?
Ever since I put up this blog this is by far the question I got asked the most. Over the past 6 or so months I have deliberately avoiding linking to any roller shops because I wanted to keep this blog ad-free, figuring that this is a personal blog and as such it should be unbiased.
Recently, however, I decided to approach several online shops that I think are good, offering to link to them in the condition that they will provide readers of this blog with a significant discount.
Several shops responded positively, and I chose the one I like the most:

Dr. Roller SHOP

USAGE
Is the skin roller painful to use?
In my experience, using a 0.5mm roller on the face or body is very tolerable. However for length 1.0mm and above - most people will prefer to use a topical anesthetic (numbing cream) such as Emla.

Should I buy the 0.2mm size roller?
You need to use a minimum of 0.5mm roller at home to actually induct collagen in the skin, so there is no point to buy anything smaller than that as far as anti-aging is concerned.

How exactly do I perfom a rolling session (sterilize the roller, clean the skin, roll etc.)?
See my Complete Rolling Guide.

Can I use the roller on any part of my body?
Microneedling with the dermaroller can be carried out on almost any part of the body (arms, legs, thighs, face, neck and even the eye area). The only exception is the eyelids because the skin there is too thin.

How often should I roll an area?
If you go to a clinic or a beauty salon, this is what they'll usually tell you :
For stretch marks, 1-3 treatments are recommended, 6-8 weeks apart. For the face, 3-6 treatments, 3-4 weeks apart. The reason for the long intervals is supposedly the time it takes for the skin to heal. When injured, the skin builds itself in 3 phases, which continue long after the initial inflammation. The idea is that using the roller too often will disrupt this process and eventually delay the results, or worse.
I have seen some respectable sites saying that you can use a 0.5mm roller (on the face) up to 5 times a week (at least for the first 3 months).
On forums, some people report that they are using a 1.5mm roller on the body once or twice a week. This seems wrong, the body doesn't recover that fast.
My personal "compromise" is (and I don't guarantee that it's correct) :
1 treatment every 3 weeks (at minimum) for stretch marks and scars (with a 1.5mm roller).
twice a week for a 0.5mm roller and
once every two weeks if using a 1.0mm roller.

How much pressure should I apply when rolling?
A lot of people are worried whether they're pushing the roller too hard into the skin or, alternately, not hard enough.
I suggest to always start rolling gently and then gradually increase the pressure AS MUCH AS POSSIBLE. You generally do not have to worry about pushing too hard, because there is no risk getting the needles deeper than their own length. For example, if you're using a 1.5 mm roller, then even if you push very hard, you won't get the any deeper in the skin than 1.5mm.
The best indication of a job well done is your skin getting red. Red means inflammation, which is what we want in this case. Of course, some people do have more sensitive skin than others. My skin, for example, gets red even at the slightest touch.
Regarding pinpoint bleeding - If your skin is thick enough like mine then you will not get ANY bleeding, and that's fine. You DON'T need to bleed to get results. Again, just be sure that you are applying enough pressure.

When can I expect to see results?
That depends on the condition you're treating , its severity, and your own general health. Generally speaking, on the face initial results should be seen after 2-3 month of excessive use (every 2-3 days, with a roller of 0.5mm or higher). For stretch marks, if a 1.5mm roller is used every 2-3 weeks, it usually takes several months to begin seeing results.
Some people report seeing results after only a week or two, it's more likely that they're just misinterpreting the inflammation (redness) of the skin as improvement. Check out my Stretch Mark Diray to see own personal progress over time.

Do I need to use any after-care products?
No. The roller only increases absorption of products that are applied during the treatment.

However, I found that applying virgin coconut oil at least 30 minutes after the end of treatment, really calms the skin and minimizes any irritation caused by rolling.

What cream or serum should I apply while rolling?
In the past my answer would be that applying a cosmetic topical while rolling is not a must but now, 5 months after starting this blog, I think this is not true.
I have tried a lot several products for rolling (Retin-A, Scacare C&E, Meso Cell Lift Up, Infadolan, just to name a few), and I believe that only those containing some form of vitamin A showed signs of working.
This includes Rose Hip oil (natural form of Tretinoin, the active ingredient in Renova).
I am currently using my own formula (I call it "Skin Restore Serum" ) which is a blend of more than 10 powerful natural oils that work together to regenerate the skin. This formula proved to be highly effective, and to the request of several readers I recently made it available for purchase.

How long does a microneedle roller last? How do I know if I need to replace it?
If you use your roller only once in every 3 or 4 weeks then it could easily last you a year or even longer. Just remember to take care of it properly (i.e. sterilize it after every treatment, keep the needles from touching any surface etc.). If you see a bent needle, throw the roller away as it could hurt your skin. If while rolling you feel that your skin is being pulled, this is also a sign that it's time to get a new roller.

THIS BLOG
Is this really a personal blog? Why aren't you revealing your real name? etc...
I got asked that a couple of times. It turns out the design of the blog came out so nicely that people think this site MUST have been created by a graphic designer...
Well, it was - BY ME! Design is my life job and this blog is just a hobby I keep. I don't get ONE CENT for publishing in this blog. Nobody and no company pays me to link to their website. If they ever do, I will let you know.
About my identity, the reason I don't reveal it is simply because I'm too embarrassed about my stretch marks and have no desire that my colleagues will be able to look up my name and come up with pictures of my butt! This is the only reason I don't publish my full name.
If I mention any product or company here, it's only because I have actually used them (after I bought them paying full money). The results I report are according to what I experience, and there's the pictures to prove it. That's all.
