What is Contractubex?

Contractubex is a topical gel formulated to prevent and treat scars. It's used on hypertrophic scars, keloids, and disfiguring scars that form after surgery, burns, injuries, or acne. The gel works on both old and new scars, though it's most effective when started as soon as the wound has closed and the skin is intact. It doesn't erase scars, but it softens them, flattens them, and lightens the red or darkened colour that makes them stand out. The skin becomes smoother, less itchy, and more flexible over time.

The gel combines three active ingredients. Allium cepa extract, from onion, has anti-inflammatory and antibacterial properties and is thought to regulate fibroblast activity. Heparin is a mild anticoagulant that improves local circulation, helping to break down the dense collagen bundles that make scar tissue hard and raised. Allantoin promotes wound healing, softens the keratin in the outer skin layer, and reduces itching. Together, they create an environment where scar tissue can remodel into something closer to normal skin.

Contractubex is applied topically, and the effects are gradual. With daily use, a fresh scar may stay flat and pale as it heals. An older, hardened scar can become softer and less noticeable over 3 to 6 months. The 15 g tube is convenient for treating small to medium areas like a surgical incision site or a few acne scars.

Mechanism and Pharmacology

The three components of Contractubex work synergistically on the three main problems of scar formation: excessive collagen production, poor blood flow, and persistent inflammation.

Allium cepa (onion) extract contains quercetin and other flavonoids that have anti-proliferative effects on fibroblasts. In hypertrophic scars, fibroblasts are overactive, producing too much disorganized collagen. The onion extract helps suppress this activity and also has antihistamine and anti-inflammatory effects that reduce redness and itching. Heparin, a glycosaminoglycan, improves the microcirculation in the scar tissue, bringing oxygen and nutrients to the area and flushing out metabolic waste. It also binds to growth factors involved in fibrosis, reducing the stimulus for collagen buildup. Allantoin is a keratolytic and humectant. It exfoliates the thick, dry outer layer of the scar, moisturizes the tissue, and soothes the persistent itch that can be maddening with keloids.

When massaged into the scar, the gel also provides a mechanical effect. The pressure and movement help break up cross-linked collagen fibers and prevent the scar from adhering to underlying tissues. This makes the scar more pliable and less likely to contract and limit movement, especially over joints. The ingredients are absorbed locally, with negligible systemic uptake, making the gel safe for long-term use.

How to Use Contractubex

Apply a thin layer of the gel to the scar 2 to 3 times a day, or as directed by your doctor. Gently massage it into the skin in small, circular motions until it's fully absorbed. The massage is part of the treatment. It takes 2 to 3 minutes of gentle pressure to make the scar more flexible. If the scar is on a joint, flex and extend the area after application to stretch the tissue gently.

Start using Contractubex as soon as the wound is completely closed and there is no more scabbing or bleeding. For fresh surgical scars, this is usually 7 to 10 days after the operation. Don't apply it to open or infected wounds. For old, hardened scars, the gel can still be effective, but it will take longer. A course of treatment for an old scar is 3 to 6 months. For a fresh scar, 4 to 8 weeks may be sufficient to see a clear improvement.

If you're treating a large or very thick scar, you can apply the gel more thickly and cover it with a piece of plastic wrap or a non-stick dressing for a few hours. This occlusion softens the tissue further and enhances penetration. Don't leave it covered all day; a few hours is enough.

If you miss an application, just apply it when you remember and continue with the regular schedule. There's no need to double up. Consistency over months is what delivers results.

Side Effects of Contractubex

Contractubex is well tolerated by most people. The most common side effects are mild and local: a temporary burning or pulling sensation on the skin right after application, slight redness, or itching. These usually pass as the gel is absorbed. The itch from the gel should not be confused with the deep, persistent itch of a healing scar; the latter is often a sign that the scar tissue is active, and the gel can help reduce it over time.

Allergic reactions are rare but can happen, usually to the onion extract or the preservative in the gel base. If you develop a spreading rash, hives, swelling, or intense burning that doesn't go away, stop using the gel and wash the area with mild soap and water. Seek a doctor's advice if the reaction is severe.

Contractubex is not a bleach. It doesn't lighten the pigment of healthy skin, but by normalizing the scar tissue, the reddish or brownish discoloration of the scar itself gradually fades to match the surrounding skin tone more closely.

High-Risk Groups (Elderly, Pregnancy)

Pregnancy. Contractubex is a topical gel with ingredients that are not absorbed in significant amounts. Allantoin and heparin are commonly used in pregnancy skincare products. Onion extract has no known systemic effects. It is considered safe to use during pregnancy and breastfeeding for scar management, particularly for cesarean section scars once the incision has healed. However, it is always good practice to check with your obstetrician before starting any new treatment.

Breastfeeding. Topical application of Contractubex to a healed scar is safe during breastfeeding. It should not be applied directly to the nipple area to prevent the infant from ingesting it.

Children. Contractubex can be used safely on children for scars from minor injuries or surgical procedures. The massage technique may need to be adjusted to be gentler and quicker, but the gel is gentle enough for a child's skin. Do not let the child ingest the gel.

Elderly patients can use Contractubex without restrictions. Older skin is thinner and more fragile, so the massage should be done with light pressure to avoid damaging the skin. The gel can be particularly helpful for preventing contractures over joints that limit mobility.

Interaction With Activities (Driving, Alcohol)

Contractubex is a topical gel that does not affect your alertness, coordination, or ability to drive. There is no interaction with alcohol. You can go about all your daily activities as normal, including showering and exercising. The gel absorbs quickly and does not leave a sticky residue, so it won't stain clothing.

Drug Interactions

There are no known drug interactions with Contractubex. The active ingredients work locally in the skin and do not enter the bloodstream in amounts that could affect other medications. You can safely use it alongside any oral or other topical medications. If you are using other topical treatments on the same area of skin, it's best to apply them at different times of day to avoid diluting or washing away the other product.

Alternative Options

Contractubex is one of several evidence-based options for scar management, and the best approach often combines multiple methods.

Silicone gel sheets or silicone ointments are the gold standard in scar management, according to most dermatology guidelines. They form a protective, hydrating barrier over the scar that reduces collagen production and flattens the tissue. Silicone sheets are reusable and particularly good for raised scars, but they can be visible and don't allow massage. Silicone gels are invisible but must be reapplied.

Onion extract gels (like Mederma in the US) are similar to Contractubex but may not contain heparin. The evidence for onion extract alone is mixed, but many patients find it reduces redness and itching.

Pressure garments are used for large burn scars to physically flatten the tissue. They are custom-fitted and worn for many hours a day over months.

Corticosteroid injections or tapes (fludroxycortide tape) are used by doctors to soften and flatten keloids and hypertrophic scars. They work by suppressing inflammation and fibroblast activity more aggressively than topical gels.

Laser therapy and microneedling are professional procedures that resurface the scar and stimulate normal collagen remodeling. They are often combined with topical treatments like Contractubex to enhance results.

Getting the Most Out of Contractubex

Massage is not optional. The active ingredients need to be worked into the tissue. The mechanical action of massaging a scar for a few minutes, twice a day, is as important as the chemical effect of the gel. Press firmly enough to feel the scar tissue move under your fingers, but not so hard that it hurts or turns white. Over several weeks, you'll feel the tissue become softer and more pliable.

For best results, combine Contractubex with sun protection. New scar tissue has almost no melanin and burns very easily. A single sunburn can permanently darken a healing scar, making it much more visible. Keep the scar covered or use a high-SPF sunscreen on it every time you go outside. This alone makes a big difference in how the scar will look a year later.

Contractubex is a time commitment. It does not erase a scar overnight, but with consistent use, the scar will become flatter, paler, and less bothersome. Take a picture before you start and another every month. The slow improvement is easy to miss day-to-day, but the photos will show you the gel is working.

Frequently Asked Questions

How old of a scar can Contractubex treat?
It works best on scars that are less than a year old and still actively remodeling. However, even scars that are several years old can show improvement in texture and color with persistent use over 6 months or more. Very old, mature scars are less responsive, but the gel can still reduce itching and make them more comfortable.

Can Contractubex remove a scar completely?
No topical treatment can make a scar disappear entirely. A scar is fibrous tissue that replaces normal skin. Contractubex can significantly improve the appearance, making it flatter, softer, and closer to your natural skin color, but it will not leave perfect, unscarred skin.

Can I use Contractubex on my face?
Yes, it is suitable for facial scars, including acne scars. Be careful to avoid the eyes, and don't apply it to active pimples or broken skin. For rolling or atrophic (depressed) acne scars, gels have limited effect, and professional treatments like microneedling work better, but Contractubex can help smooth the surface texture.

Does the gel work on stretch marks?
Contractubex is formulated for scars, and the science is similar. While the company doesn't claim it removes stretch marks, the heparin and allantoin can improve the color, texture, and itchiness of fresh, red stretch marks. It is less effective on old, white, silvery stretch marks.

Can I apply makeup over it?
Yes. After massaging the gel in completely, let it dry for a few minutes. Then you can apply sunscreen, moisturizer, or makeup over it.
