All hyaluronic acid syringes in our range are so-called cross-linked, highly purified, sterile-packed medical products.

Singfillers are cross-linked hyaluronic acid syringes in a disposable format. The products are approved medical devices in Europe and have all certificates. Cross-linked hyaluronic acid preparations are used to fill tissue, for example to enlarge lips or inject wrinkles.

Our company dispenses with costly sales and marketing. As a central importer and registered medical device distributor, Intraa does not employ any sales representatives, does not exhibit at any costly trade fairs and does not make any further marketing efforts, such as glossy brochures or testimonials from celebrities who would be paid to do so. This allows the customer to buy directly from the manufacturer without having to pay the considerable marketing and distribution costs (approx. 2/3 of the total sales price).

Why are their products so cheap and when I go to a doctor, is the treatment so expensive?

At Intraa you can see the prices at which a doctor can buy.
If the doctor charges you a higher amount for the entire treatment, then you know approximately how much the hyaluronic acid injection itself cost and how high the ancillary costs and the doctor’s fee are.

In simple terms, the products can be divided into low-viscosity and very viscous consistencies. Experts call these “viscosity grades“.

Intraa offers you four different viscosity levels.
As a rule, thinner viscosities (Singfiller Fine V1) are more suitable for small and superficial wrinkle fillers.
Thick consistencies (Singfiller Deeper V4) are intended for deeper volumes or larger areas.

Our group of companies is called Ascendens and we are based in Eckental near Nuremberg in northern Bavaria. INTRAA is our business unit for medical devices in aesthetic medicine.
We are the European general agency for one of the world’s largest manufacturers of hyaluronic acid products and part of the group of companies.

Our hyaluronic acid syringes are medical products approved in Germany and the EU.
Their use on third parties is reserved exclusively for doctors and alternative practitioners in Germany.
Self-treatment is permitted, although only recommended if the relevant expertise is available, as there may be a risk of vessels or nerves being hit.


Under no circumstances is an initial treatment recommended if the patient has never been injected with hyaluronic acid before. Self-treatment is always at your own risk and responsibility!

It is forbidden to treat third parties, including friends or acquaintances, without being a doctor or alternative practitioner in Germany. If cosmetic institutes or even laypersons do this, it is against the law.

If you have professional expertise, self-treatment is not prohibited, but it is not recommended either. Ideally, injections should be carried out by an experienced aesthetic physician.

Side effects of pure hyaluronic acid are practically impossible because it is a biological substance that also occurs in the human body. However, if other suppliers fill in additives (for example: lidocaine or vitamins), the composition of the active ingredients changes and allergic shocks may occur.
In addition, professional knowledge of anatomy must be ensured for all injections. In particular, it must be avoided that vessels or nerves are hit during the injection or that too much solution is injected into a site that blocks the supply vessels and leads to undersupply of a surrounding area.

In Europe, we only sell hyaluronic acid in 1ml syringes. They are medical products and there are very few applications where more than 1 ml is required.

Basically, cross-linked hyaluronic acid is an organic (vegan) product that is produced by biofermentation and is natural. It also occurs in the human body. All manufacturers who have undergone certified processes and do not add any additives (such as lidocaine or vitamins) must fill pure hyaluronic acid with water only. Only the viscosity can change. Most expensive brands without additives are only expensive because of the high sales and marketing costs involved, but are otherwise directly comparable with our products.

The minimum shelf life is designed for normal room temperature (18 – 20 degrees). From 28 degrees and above, the best-before date should be avoided in any case. Below 5 degrees, thicker or freezing consistencies may occur. The recommended temperature range is therefore between 15 and 22 degrees. Direct exposure to sunlight or even (conversely) freezing temperatures should be avoided at all costs.

As a retailer who complies with all Medical Devices Act guidelines, you may resell to other specialist retailers who comply with these Medical Devices Act guidelines, as well as to doctors and alternative practitioners.

Derma fillers with cross-linked hyaluronic acid are medical products and do not require a prescription. They are not medicines, although they may be sold through pharmacies. Singfillers are also not pharmacy-only, but can be sold in a pharmacy or directly to medical professionals via a specialist retailer. A prescription does not have to be issued by a doctor.

We supply our hyaluronic acid products exclusively with two sterile-packed disposable cannulas. This ensures that the user has a second, sterile cannula in the event that a second puncture into the target tissue is necessary, or in the event that the first cannula used becomes unsterile during handling, the second sterile cannula can be used. It is a free service provided by Intraa.
In over 90% of cases, the second cannula is not required.

For the treatment of the lips, we recommend using Singfiller Fine V1 or Singfiller Derm V2

For the treatment of frown lines, we recommend the use of Singfiller Deep V3 or Singfiller Derm V2

For the treatment of nasolabial folds, we recommend the use of Singfiller Deep V3 or Singfiller Derm V2

For the treatment of pleats, we recommend the use of Singfiller Fine V1

For the treatment of marionette lines, we recommend the use of Singfiller Deep V3 or Singfiller Derm V2

Hyaluronic acid syringes vary in their viscosity, which influences their areas of application. Low viscosities are suitable for finer lines and wrinkles as they are easy to spread and smooth.

Medium viscosities are more versatile and can be used for wrinkles as well as for more volume. These offer a good balance between suppleness and structure.

High viscosities, on the other hand, are particularly suitable for deep wrinkles and facial modeling, as they offer more substance and lifting power.

The choice of viscosity depends on individual needs and the desired result, whereby careful coordination is crucial to achieve natural and aesthetically pleasing effects.

As the application with the HyaluronPen is very specific and can lead to unpleasant side effects if not carried out correctly, the responsibility for the entire application lies with the user.
We know that many customers pour our products into the HyaluronPens at their own risk and have had very good experiences with them, as the degree of purity of SINGFILLER is even higher than that of most hyaluronic acid gels.
Doctors use our FINE (V1) for this purpose at their own responsibility

However, our products are not legally approved for decanting into a HyaluronPen and we assume no liability.

No, that’s not possible. Our hyaluronic acid preparations are medical products and are supplied with sterile needles for injection into the skin tissue.

Depending on the application site and the patient’s wishes, the injection techniques can be completely different. The professional associations for doctors and alternative practitioners offer courses and specialist training for various injection techniques. Our company itself does not offer this because it would be cost-intensive and would then be added to the purchase price. Please contact your professional association.

Our singfillers do not contain lidocaine (anesthetic), but are high-purity cross-linked hyaluronic acid for building up tissue or injections for a volume increase that is intended to last for a long time. Lidocaine is a pharmaceutical preparation and may only be sold through pharmacies, our company is a medical device distributor and does not sell pharmaceuticals.

Basically, singfillers are first injected into the correct layer of skin with the cannula and then it is almost always necessary to gently massage the shape into the anatomy with the fingertips. Under no circumstances can hyaluronic acid be massaged in from the outside without injection needles.

Our Singfillers do not contain any additives that could trigger an allergy. Hyaluronic acid is allergy-free without additives.

Singfillers are medical devices that are approved for single use only. Even though we know that some doctors store leftovers in the syringe in the refrigerator for a few days in order to re-inject the same patient, we do not consider this procedure to be advisable because an infection cannot be avoided for hygienic reasons. In addition, it is not approved as a medical device and the syringe, including any residue, should be disposed of properly after the treatment session.

A typical phenomenon is a swelling of the body’s own water after the injection. This can lead to significantly disproportionate water retention, which can worry the patient. This water retention is normal and occurs frequently. They usually disappear within 48 hours and only the hyaluronic acid remains as and where it was injected. Patients must be informed about this endogenous water swelling. Lumps are usually a sign that hyaluronic acid has been injected at one or more points and has not been massaged out well enough with the practitioner’s fingers. Massaging away lumps or swellings in turn causes the body’s own water to accumulate for approx. 24 – 48 hours and should not worry the patient. The practitioner is urgently advised to point out that this overreaction with the body’s own water has no side effects, but is only a temporary effect.

If more volume than desired has been injected in one area by mistake, the method of choice is to massage it around with the practitioner’s fingertips to achieve better distribution. If this does not yet have the desired effect for the patient, he can either wait a few days or weeks until the hyaluronic acid volume has reduced again through natural degradation. In the event of a significant overdose, the doctor can completely dissolve a hyaluronan injection within hours by injecting hyaluronidase. However, this technique is reserved exclusively for doctors.

In principle, there is no chemical interaction with pure hyaluronic acid and botulinum toxin (Botox), but the practitioner should carefully consider the different principles of action when using hyaluronic acid and Botox. While hyaluronic acid builds volume, Botox is a neurotoxin that numbs the muscles. This can have positive, synergetic effects, but it can also interfere with each other.

We recommend the use of sharp needles, such as those contained in the disposable packaging. Our injection concept is based on a few punctures, whereby the practitioner does not move the cannula tip back and forth or rotate it several times in the injection channel. If this is intended to achieve a particularly successful treatment, blunt cannulas are also available from specialist retailers. However, these require a special technique and are available in more than 20 different variations: lengths, diameters and stiffnesses. As a rule, the cannulas contained in the Singfiller packaging are the method of choice and are more than sufficient.
