Result(Before and After)

1. Derma Roller treatments are great to be used for improving your skin tone, and texture and reducing pigmentation concerns like aging spots. For best results, we suggest using a whitening derma roller serum.

2. Hair loss may be caused by many reasons and it is very important to cure the cause. Derma roller treatments help to reduce hair follicle exposure and suppress seborrheic dermatitis, which improves the scalp and prevents hair loss.

Derma roller treatments for hair loss should be performed in combination with suitable hair loss drugs.

3. Stretch marks are the result of damaged elastin, which makes up part of the dermis layer. Stretch marks appear especially with someone who experiences sudden weight gain as happens with pregnant women or even bodybuilders. Derma Roller treatments are effective to reduce the appearance of stretch marks.

4. As we age, our skin seems drier, thinner, and with reduced elasticity, as a result of this, we see that our skin is no longer shining youthfully, and fine lines appear. This happens because inside our skin hyaluronic acid and the number of cells that generate the substance are greatly reduced as we age.

Derma roller treatments slow down the aging process by stimulating collagen self-regeneration that improves the appearance of wrinkles and skin pigmentation like aging spots as well. Derma roller also helps to enhance skin elasticity & reduce open pores.

FAQ

1. What is Microneedling?
Microneedling is a non-invasive procedure that involves using a derma roller that has many fine, very sharp medical quality needles. The rolling action over the skin causes fine holes to puncture into the deep layers of the skin. This promotes your skin's own healing mechanisms to stimulate new collagen growth, improve skin texture and reduce the appearance of scarring and fine lines.

2. Does microneedling hurt?
Different body areas are not with the same sensitivity – facial areas tend to need numbing with smaller derma roller needle length, and other body areas like thighs may not require numbing.
Using your roller gently gives a kind of tickling feeling and is not painful. You may find that there is a temporary reddening of the skin for around an hour after treatment and it can give a sensation similar to mild sunburn. We recommend the use of vitamin-rich treatment cream after use and sunscreen/block if you will be exposed to the sun after treatment.

3. Is Derma Roller treatment safe?
Yes, it is. “Non-surgical and non-ablative” means skin-friendly treatment.  You experience little or no pain, downtime, and risk of complications. Original Dermal Roller is registered & licensed.  Also, there is no permanent damage caused to the skin during microneedling. The micro-injuries created by the dermaroller will trigger your skin to renew itself, making your skin more healthy & youthful.
Do not accept treatments done by cheap Rollers with poor-quality needles which may cause skin drag, allergy, or skin damage.

4. What areas can be treated with the dermaroller?
Microneedling can be carried out with a Roller on almost any part of the body: the arms, hands, legs, thighs, body, abdomen, neck, face, cheeks, scalp, even around the eye area – such as crow’s feet and frown lines. But you shouldn’t use dermaroller only on your lips and eyelids (the skin there is very thin & you risk damaging your eye with dermaroller).

5. Who is suitable for the procedure?
The ones with stretch marks, wrinkles, scars, cellulite, hair loss, uneven skin tone, acne scars, and enlarged pores are all due to a lack of collagen and are all suitable for the treatment, so using a Derma Roller to replace the collagen you can help your skin renew and repair itself to a cosmetic level. Derma Roller therapy, also known as micro-needling, is an all-natural cosmetic procedure that can be done in the comfort of your own home.

6. Who is not suitable for microneedling?
Contraindications and precautions include:

• Keloid or severely raised scars;
• Eczema, Psoriasis, active Acne, Rosacea, or other chronic skin conditions;
• Actinic (Solar) Keratosis;
• Diabetes (delayed wound healing);
• Presence of raised moles, warts, or lesions within the treatment area;
• Herpes Simplex or Zoster infections (treatment can trigger breakouts).

Absolute contraindications include:
Scleroderma; Blood clotting problems; Collagen vascular diseases; Cardiac abnormalities; Immunosuppression; Active bacterial or fungal infections; Scars less than 6 months old; Facial fillers injected within the last 6 weeks.

7. Can the Derma roller be performed on any skin color?
Since Derma roller does not use thermal heat (unlike IPL & Lasers) it is safe to use on all skin types and all skin colors. There is no risk of post-inflammatory hyperpigmentation.

 8. How often can you have a treatment?
It will normally take up to 30 minutes for the topical and aesthetic to work and 20 - 30 minutes for the Microneedle therapy procedure. For Collagen Induction Therapy, we recommend starting with 3 treatments, but with a minimum separation time of 6 to 8 weeks between treatments. For Scar Reduction Therapy, an average of 3 to 5 treatments are recommended, with an improvement of 70-80%. Unlike ablative procedures for facial skin only, the Derma roller can be used on all skin parts of the body (neck, décolleté, arms, legs, etc.).

9. How long does it take to see results with the dermaroller?
The rate at which you will get results depends on what condition you are treating and how extensively your skin needs to remodel. This process of skin remodeling can continue for literally months after each Derma Roller treatment, but visibly noticeable changes can be seen within a week! Your skin naturally renews itself every 40 days, so with a little stimulation, changes can be dramatic and fast.

10. How is the Derma roller procedure performed?
The skin is cleaned and afterwards numbed with an appropriate numbing cream so it should not hurt at all. Skin is thoroughly needled in such a way, that each skin part is needled about 15 to 20 times. An even flushing is the best indication of a perfect medical performance.

11. What should you do after the treatment?
A professional moisturizing cream/lotion will be applied after the procedure to help soothe and calm the skin, continue to use until the redness has cleared.  You should also apply a broad spectrum UVA/UVB sunscreen with an SPF 30+. Continue to apply on a daily basis for at least two weeks even during the winter or on cloudy days.  Use tepid water to cleanse the face for the following 48 hours and dry gently, always make sure your hands are clean when touching the treated area.  It is recommended that makeup is not applied for 12 hours after the procedure. Following the treatment as the skin starts to regenerate and repair, it may well feel drier than normal. 

12. What are the side effects of a Derma roller procedure?
Your skin is likely to redden after use. This should fade within a few hours. In extreme cases, this may last for 24 hours. There are virtually no negative side effects, and none have ever been reported in over 150,000 procedures performed worldwide.

13. Do you have to use a gel or cream?
The roller facilitates tiny channels/holes for it to literally go into the skin - painlessly. Needling stimulates blood flow and collagen re-growth. Skin care products used with rolling are extremely beneficial. You can use Vitamin A and C, copper peptides, or a high-quality, vitamin-enriched active ingredient moisturizer.

Some people use the numbing cream for cellulite and face needling. Others feel it is not necessary and claim that the Derma roller is a little irritating or tickles, and then you get used to it, in other words not painful. So it is trial and error and varies from one person to the next.

14. Do you need to sterilize my roller after use?
Yes, it is essential to keep your roller in a clean and sterile condition. Wash in hot running water after every use. Then stand head first in half your plastic cylinder (that the roller comes in) of disinfectant for about half an hour. Shake off excess liquid and dry on a clean towel or paper towel. Put a cap on and store in a clean sealed container - supplied.
Also never share your dermaroller with another person due to probable cross-contamination.

15. What type of disinfectant should you use?
Just buy a small bottle of disinfectant from the first-aid section of your supermarket or pharmacy. Fill your plastic cylinder 1/4 full with disinfectant, and 1/4 water, so the cylinder is half full. Put roller in head first for about 1/2 an hour. This sterilizes your roller as well as the plastic cylinder you store it in.

16. How long does the dermaroller last?
Our dermarollers are of high quality, and with the proper care, they will last approximately one year. The needles will not wear out as much (as they are medical-grade). For one Derma Roller, we suggest you use it no more than 10 times with the proper sterilization after and before every use.
