Scarend Silicone Gel is a topical skin-care product marketed in Hong Kong as a silicone-based gel that comes in a 15 g tube. According to the product label, the active ingredient is cycloserine. Silicone gels are widely used to improve the appearance of hypertrophic and keloid scars, while cycloserine is an antibacterial agent traditionally used for tuberculosis treatment. This article combines the known properties of both silicone gels and cycloserine to give a balanced, evidence-based overview of the product.
Silicone (polydimethylsiloxane) forms a flexible, breathable film on the skin. This film:
These mechanisms are well documented for silicone-based scar therapies and are the primary reason silicone gels are recommended by many dermatology societies.
Cycloserine belongs to the class of antibiotics that inhibit bacterial cell-wall synthesis. Its established clinical use is in multidrug-resistant tuberculosis. Evidence for cycloserine’s activity on skin tissue is limited, and the product’s label does not provide specific mechanistic data for topical use. If cycloserine reaches the skin surface, it may exert:
Because the topical pharmacokinetics of cycloserine are not publicly available, the contribution of this ingredient to scar remodeling remains uncertain. The silicone matrix is the component with the most established efficacy for scar improvement.
In Hong Kong, Scarend Silicone Gel is classified as a cosmetic/medical-device product rather than a prescription drug. The Department of Health (DH) regulates silicone scar-care gels under the Cosmetics Ordinance and the Medical Device Regulations. The product is approved for external use to:
No formal indication for treating skin infections, acne, or other dermatologic conditions has been granted by the Hong Kong DH.
There are no peer-reviewed studies that support off-label uses of Scarend Silicone Gel for conditions such as wound healing, acne, or eczema. Any investigation into alternative applications would be experimental and must be conducted under clinical supervision.
Off-label use requires medical supervision and individualized risk assessment.
If you fall into any of the categories above, consult a pharmacist or dermatologist before starting the gel.
No specific drug-drug interaction studies have been published for topical cycloserine. As a precaution:
Always read the accompanying patient information leaflet for product-specific instructions.

Fresh, open wounds lack the protective epidermis required for silicone gel application. Applying the gel may trap bacteria and impede healing. It is best to wait until the wound has fully epithelialized before using the product.
Clinical observations with silicone gels suggest visible improvements after 8-12 weeks of consistent twice-daily use, although individual results vary.
Silicone creates a semi-occlusive barrier that repels water but is not completely waterproof. Normal bathing or showering does not usually remove the gel, but vigorous scrubbing should be avoided.
The tube typically bears the brand name “Scarend” printed in black, along with the dosage strength “15 g” and a batch number. No universal imprint code exists for this product.
Yes, once the gel has fully dried (typically 5-10 minutes), a light layer of non-comedogenic makeup can be applied. Avoid heavy or oil-based cosmetics that could disrupt the silicone film.
No. The product is sold over the counter as a cosmetic/medical-device item. However, a pharmacist may provide usage guidance.
According to the ingredient list, the formulation is fragrance-free and does not contain parabens. Always review the full label for other potential allergens.
No direct interaction has been documented. However, applying multiple layers may affect absorption. If you use a corticosteroid, apply it first, allow it to dry, then apply the silicone gel.
Yes. The product complies with Hong Kong’s aviation liquid allowances (containers ≤100 ml). Keep the tube in a clear, resealable plastic bag for security screening.
Both silicone sheets and gels work by the same hydrating mechanism. Preference often depends on convenience, scar location, and patient comfort. No head-to-head clinical trial directly comparing this specific gel to sheets has been published.
