Why do they get them?

First of all, as a hundred years ago, no one is immune to accidents, fires, attacks and diseases, which often end in surgery.
Secondly, plastic surgery is actively developing these days. People want to look better and they voluntary go for surgical procedures, thereby falling into an increased risk zone. Therefore, as a result, they have to think in advance about a strategy for getting rid of unattractive defects.

And finally, unpleasant scars on our body can appear without the participation of doctors. We do sports, do physical work, use dangerous equipment, and our children just love outdoor games.

Scars do not disappear by themselves. They need to be treated. There are many methods for this: corticosteroid injections, cryotherapy and silicone gels. The presence in this list of silicone gels proves that it is not necessary to get rid of scars in the hospital. This can be done at home. The results of the use of this medication evidence high efficacy of silicone gels and their safety.

We all want to look beautiful and flawless, regardless of age group, and scars and keloids on our skin often make us nervous and embarrassed. Some of these marks are almost invisible and do not cause much concern, while others are quite visible, and this sometimes puts us in an awkward position. Everyone wants to get rid of scars and keloids left on the skin after acne, surgeries, burns or injuries, but it is quite difficult to do.

There are various medical ways for the prevention and treatment of scars after injuries, burns or striae, as well as for the elimination of skin scars resulting from acne or pustules. It is possible to make postoperative scars and keloids less noticeable by applying various gels and ointments. One of the most famous preparation is “Contractubex”.

What is Contractubex?

This is a combination medication, the effect of which is due to the properties of its components. The action of the product is aimed at accelerating the healing of postoperative scars, activating tissue regeneration in case of skin lesions. The composition of the gel, according to the instructions for use, includes heparin, allantoin and onion extract, the properties combination of which provides pharmacological properties.

The gel helps very well to eliminate enlarged and thickened scars that occur after surgery, amputations, burns, and injuries. It is often recommended as a remedy against striae after pregnancy. It is also used to treat scars that occur after acne and furunculosis and to prevent the formation of pathological scars in the postoperative period or after an accident.

  • Contractubex gel forms a thin film; it has almost no odor and can be applied to all skin areas, including the face, joints, and folds. In the course of treatment, scars become soft, elastic and in some cases become almost invisible.
  • Contractubex comes in the form of ointment and gel, and the latter even is produced for children use.

There is a general recommendation that gels and ointments should be applied from the earliest postoperative period or immediately after the wound has healed. In order to ointments act, you need to use them regularly for a long time.


There are several precautions that should be followed when using this product. For example, Contractubex gel cannot be applied to an open wound. In addition, if there is a history of allergic reactions to any of the substances included in the composition of the drug Contractubex, its use should either be canceled or carried out under the supervision of a physician. Also, do not let the medication in the eyes. In this case, immediately flush eyes with warm water.

In the treatment course of scars of any origin, it is necessary to avoid direct sunlight and hypothermia, because in such conditions, the effectiveness of the medication is reduced. Also it is recommended exclude strong massage.

You should also be aware that drug Contractubex cannot be used to treat children under the age of 6 months. However, the use of the preparation in older children is permissible after consulting with a doctor and specifying the scheme and duration of treatment. If the child is prone to allergic skin reactions, it is necessary to ensure that there is no allergy to any of the components of the drug.
Due to the low systemic effect of topical agents, their use during pregnancy is not contraindicated. However, in order to avoid negative consequences, it is necessary to coordinate the treatment course with the specialist supervising the pregnancy.

The active components of the gel do not penetrate into the systemic circulation and other body fluids of a woman, including breast milk. However, taking into account that the use of the drug during pregnancy and during breastfeeding is not well understood, most experts do not recommend combining the use of Contractubex with a lactation period. In this case, therapy is delayed until breastfeeding is complete.

The decision on the use of Contractubex as a prevention measure against striae is made individually by the attending physician.

Before you start using this medication, you should carefully read the instructions attached to it.


It is usually recommended to use Contractubex at the rate of 5 mm of gel per 20-25 cm of the scar surface of the skin. Anyway, the treatment regimen is prescribed by the attending physician. Remember that in no case Contractubex should be applied to an open wound.

How to take Contractubex?

Gel Contractubex rubbed into the damaged surface of the skin 2-3 times a day with light massage movements, moving the palm from the center of the damaged surface to its edges. The formation of a thin invisible scar depends on the smoothness of the movement and the uniformity of the absorption of the gel. The course of treatment depends on the scar or keloid age, as well as on its size and location. For example, the treatment of fresh scars is usually not more than one month. Elimination of old scars or keloids will take longer time, from 3 to 6 months.

In addition, in order to achieve an early recovery, it is recommended to apply gel on steamed skin, which will allow the agent to act more effectively.

Moreover, the treatment of Contractubex allows for a combination with physiotherapeutic procedures, which are prescribed by the specialist.

  • urticaria, rash, skin irritation, papules, redness of the skin, a feeling of compaction on the skin
  • allergy (allergic reaction).

In case of any of these reactions manifestation, as well as any other unpleasant reactions, you must immediately inform your doctor.


Cases of overdose with this drug have not been recorded and are considered unlikely. However, it should be remembered that in the case of an extraordinary situation that arises during the use of Contractubex gel, it is necessary to stop using the drug and consult a specialist.

The manifestation of side effects in most cases is associated with individual intolerance to the components of the drug; restorative therapy is not required to eliminate side effects.


Gel Contractubex can be used simultaneously with other drugs, due to the lack of systemic absorption.

However, if the patient is prone to any allergies, you should carefully monitor all possible reactions that may occur as a result of the simultaneous use of Contractubex gel and other medicines.

I have to say that at first no results were noticeable, but a month later the skin leveled off and the color of the scar changed, it became almost invisible. I was enough 1 tube of 20 g for the whole treatment course.

As it was recommended I applied gel three times a day. Two months later, the place of the burn healed completely and now there is no different from the adjacent skin.

Sally: I bought Contractubex for the treatment of fresh postoperative scar left on my body after a serious abdominal surgery. I really wanted to minimize the external consequences of the surgical intervention, and I hoped that this famous German drug would help me.

A couple of weeks after the surgery, when the suture more or less healed and I got the opportunity of daily and independently treat it, the doctor advised me to use gel Contractubex. I started using it. During the first month I rubbed preparation into the scar every day. Healing went without complications and quickly. Now, three months later, the scar is almost invisible.

I had another keloid, which was formed as a result of a burn 12 years ago. I decided to try this medication again. During the last five months I use this agent to treat my keloid. Every day, in the evening after a shower I rubbed it into the keloid tissue. After five months of using the medication, the keloid has become completely flat, and the surface of the skin looks completely smooth.
