Frequently asked questions
Croma HA filler treatments are non-surgical, granting minimal recovery time and ensuring, immediate, natural-looking results. Depending on your skin and individual wishes, the practitioner will choose the most suitable product from the Croma HA filler range to fulfill your needs and expectations. The resemblance of naturally occuring HA in the human body and Croma HA fillers means no preliminary allergy testing is necessary. The procedure is quick and easy. The injection itself may only take about 15 to 30 minutes. You will be able to return to your daily activities immediately afterwards.
Most people find filler injections quite painless. The addition of lidocaine, a mild anaesthetic, to certain products makes the injection even more comfortable for you. In addition, Croma HA fillers are placed in your skin by using thin wall needles which are specially designed for optimal patient comfort. An anaesthetic cream or local anaesthetic injection can be applied additionally depending on the area to be treated and your sensitivity.
The results of an aesthetic treatment with Croma HA fillers are long lasting, but not permanent. Depending on the product used, the injection area and your individual dispositions of the skin, the results can last for several months up to a year.
It is important to talk about your expectations and wishes with your aesthetic practitioner before going ahead. You will be asked to inform your doctor about your previous medical history and prior aesthetic treatments with other products. In the week prior to the treatment with Croma HA fillers, you should not take any platelet aggregation inhibitors (such as Aspirin™, Marcoumar™ etc.) or anti-inflammatory medication in order to reduce the risk of bruising and bleeding at the injection site.
In order to achieve optimum treatment results, you should allow your skin to rest and not touch the treated areas on the day following treatment, not apply any make-up to the treated skin areas for at least 12 hours, avoid sunbathing and high temperatures as well as saunas and steam rooms for the first week after treatment. In case you experience any post-treatment discomfort, you can apply an ice-pack for a brief period on the injection site to help soothing any swelling.

- people who tend to develop hypertrophic scarring or have a susceptibility to keloid formation

- women who are pregnant or breast feeding

Croma is a leading specialist for injectable hyaluronic acid and applies the highest standards in order to guarantee the best quality and safety. Please bear in mind that the use of Croma HA fillers – despite its optimal quality – may cause some post-treatment discomfort or side effects, which can appear immediately after the injection or after a few days.
There may be mild reddening and swelling at the injection sites, which will normally disappear on their own after a few hours. Apart from light bleeding due to the injection, mild oedemas or erythemas can develop, which can be itchy or painful on pressure. In rare cases, small hematomas, indurations and nodules can form in the treated areas, which will dissipate within a few days. These reactions can last for one week. Please inform your aesthetic practitioner if inflammatory reactions or other adverse events last for more than one week, so that they can be adequately treated*.
