Hiruscar Ultra Scar Care Gel is a topical gel built around four active ingredients: Allium Cepa (onion extract), Niacinamide, Acetyl Hexapeptide-49, and Centella Asiatica. Unlike a silicone scar gel, it does not form a surface film — instead it relies on several biological mechanisms at once. The onion extract calms inflammation and helps regulate excess collagen production, niacinamide fades dark marks and discolouration, centella supports orderly collagen structure, and acetyl hexapeptide-49 helps ease tension at the scar edge. The gel itself is clear, non-sticky, and absorbs quickly, making it easy to use daily for both scar care and brightening in one step.

Hiruscar Ultra Scar Care Gel is used on both raised (hypertrophic) scars and flatter scars that remain darker than the surrounding skin, including scars from surgery, caesarean delivery, acne, ear piercings, and everyday injuries. What sets it apart from other scar gels is its added focus on the dark marks and discolouration left behind once a wound has healed, making it a fit for anyone concerned about uneven scar pigmentation. It is not designed for deep pitted acne scars or stretch marks, which need a different type of skin-remodelling approach.

Clean and dry the scarred area before every application. Squeeze out a small amount and massage it gently in circular motions until absorbed, twice daily — morning and before bed. The gentle massage helps the actives penetrate and eases tension around the scar at the same time. Continuous use for at least 4-8 weeks is needed before dark marks start to fade, and 2-3 months or more for a clear change in raised scars. The 5g tube suits one or two small-to-medium scars and can be used on the face or body. No dressing is needed afterwards.

Side effects from Hiruscar Ultra Scar Care Gel are uncommon — occasional itching, mild stinging, or redness at the application site, particularly in anyone sensitive to onion extract or with reactive skin. Safety data on onion extract gel shows a slightly higher irritation rate than using nothing at all, so a small patch test on normal skin for a day or two beforehand is worthwhile. If swelling, burning, or a spreading rash occurs, stop immediately, rinse with clean water, and consult a pharmacist or doctor before reapplying.

Do not apply to open wounds that have not fully closed, infected skin, pus, or inflamed injuries. Avoid the eye area and mucous membranes. Anyone with a known sensitivity to onion or plant extracts should patch-test a small area first. For very new scars that are still swollen and red, check with a doctor before starting, and keep the treated area out of strong sun exposure during treatment since it stays prone to renewed dark discolouration. If it accidentally gets into the eyes, rinse immediately with plenty of clean water, and seek medical help right away if swallowed.

Hirudoid Cream (Mucopolysaccharide Polysulphate) uses an MPS formula that boosts local blood circulation, better suited to bruising and blood pooling than raised scars or dark marks — a different problem area from Hiruscar Ultra. Dermatix Ultra Gel (Polysiloxane) is a true silicone gel focused purely on forming a moisture-sealing film, with no bioactive or plant-extract ingredients, suited to hypertrophic scars and keloids that need continuous film coverage — a different approach from Hiruscar Ultra's bioactive-ingredient focus on fading dark marks alongside scar care. In short: choose Hiruscar Ultra when dark marks are a concern alongside the scar, Dermatix Ultra for hypertrophic scars and keloids needing a silicone film, and Hirudoid for bruising.

Hiruscar Ultra Scar Care Gel can be used alongside sunscreen as usual — let the gel absorb fully first, then apply sunscreen on top, since scars and dark marks are especially sun-sensitive. Avoid layering another scar treatment product over the same area at the same time. Leave at least a one-day gap if switching to a different scar product. Regular make-up can be applied once the gel has fully absorbed.

Onion extract gel does not work instantly. Most people notice dark marks fading within 4-8 weeks of daily use, while raised scars need longer, usually a clear change only appearing after a full 2-3 months. Fresh scars tend to respond faster than scars that have been present for years. Applying and massaging it consistently every day matters more for how quickly results appear than how much gel is used per application.
