Fermenkol and Contractubex are marketed for scars, but neither product name tells us whether a scar is immature, hypertrophic, keloid, acne-related, contracted or still an open wound. That distinction changes appropriate care and whether a topical gel has a realistic role.
Short answer: Do not expect either gel to erase a scar. Product formulations and labels vary by market, and evidence for many topical scar ingredients is limited. Dermatology guidance gives more established roles to wound care, sun protection and, for selected raised scars, silicone gel or sheets; severe or changing scars may need procedures rather than home treatment.
Start with the scar, not the brand
| Situation | Why it changes the plan |
|---|---|
| Open, infected or poorly healed wound | Needs wound assessment; scar gels are not a substitute for wound care. |
| Raised, itchy or painful scar | May be hypertrophic or keloid and can need dermatologist-directed treatment. |
| Scar crossing a joint or limiting movement | Contracture risk requires prompt assessment and sometimes rehabilitation or procedures. |
| Flat, healed scar with colour change | Time, sun protection and realistic expectations are often central. |
What is supported more consistently?
The American Academy of Dermatology describes silicone gel or sheets as options for raised scars and keloids after a wound has healed. That does not prove that every scar gel works the same way or that one branded gel will remove an old scar. Avoid applying topical scar products to a scab or open wound unless a treating clinician and the local product instructions say otherwise.
How to compare products safely
Use the exact local label to check ingredients, approved age, whether the skin must be fully healed, how long use is expected, allergy warnings and whether the product is meant for a particular scar type. Patch testing may be sensible for sensitive skin. Do not delay evaluation of a changing, bleeding, ulcerated or rapidly growing lesion by assuming it is a routine scar.
When to get medical care
See a clinician for a painful, hot, draining or spreading wound; fever; a rapidly enlarging raised scar; a scar that limits movement; a facial scar or burn; scar symptoms after surgery; new pigment change; or any lesion that bleeds, ulcerates or does not heal. Seek urgent care for signs of infection or a serious burn.
FAQ
Can a scar gel be used on an open wound?
Not routinely. The wound needs to be closed and healed unless the treating clinician and the exact product instructions advise otherwise.
Which gel is best for a keloid?
Keloids often need an individual dermatology plan. Silicone products, injections, pressure therapy or procedures may be considered; do not rely on a brand comparison alone.
How long do scars change?
Scars can mature slowly over months. A clinician can help distinguish expected healing from a hypertrophic scar, keloid or another condition.
