BIOCORNEUM® by Sientra is the only advanced scar treatment with Silishield® patented crosslinking silicone plus the protection of SPF 30 — to support your skin inside and out. BIOCORNEUM forms an invisible shield to create an optimal environment that can

  • prevent and minimize the formation of new scars,
  • decrease the appearance of old scars, and
  • help to restore the function of healthy skin.

What kinds of scars can BIOCORNEUM treat?

BIOCORNEUM can be used to prevent and minimize the appearance of hypertrophic (raised, red) scars and keloids. It can be used on scars resulting from surgical and cosmetic procedures, trauma, wounds, and burns, and it can be effective on old or new scars.

What is Silishield?

Silishield advances the benefits of traditional silicone sheeting through the comfort and ease of a gel. Patented crosslinking silicone creates an invisible shield that feels like a second skin and helps reduce the appearance of scars. It can reduce redness and discoloration, soften and flatten new and older hypertrophic and keloid scars resulting from surgical procedures, injuries and burns. The SPF is designed to be effective while also maintaining Silishield’s silky-smooth feel and clear appearance.

Is BIOCORNEUM easy to use?

Yes. BIOCORNEUM feels silky smooth, is simple to apply and dries rapidly. The protective shield it forms is flexible, so it moves like a second skin. It is breathable and nearly weightless, so it’s comfortable, even under clothing. It is self-adhering, so patients don’t have to worry about it peeling off or having to tape it on. It contains SPF 30 sun protection to help protect scars from sun exposure’s darkening effects. Once dry, BIOCORNEUM continues to work when makeup, lotion, or additional SPF protection is applied over it.

Is it noticeable?

After it dries, BIOCORNEUM is barely visible. You may see a slight sheen over the application area.

Is BIOCORNEUM suitable for people with sensitive skin?

Yes. It is also suitable for use on children over 6 months of age.

How does BIOCORNEUM work?

BIOCORNEUM’s key ingredient, Silishield patented crosslinking silicone, forms a protective shield over the scar area that is optimal for physiological healing and cosmetic improvement. Sunscreen agents protect the area from sun exposure’s darkening effects. Together, these factors help to keep skin hydrated and normalize excessive collagen formation that contributes to abnormal scarring. The shield also aids in protecting the underlying tissue against chemical, physical and microbial invasion.

Why is Silishield important in my scar treatment?

The International Clinical Recommendations on Scar Management 4 published in 2014 named silicone as the single recommended topical (non- invasive) treatment for scars. Silishield patented crosslinking silicone bonds with skin more effectively than standard silicone. This is crucial, because silicone is effective as a treatment only if it is truly in contact with the scar area 24 hours a day for the duration of the treatment, which can be achieved with BIOCORNEUM in only two daily applications.

How should patients use BIOCORNEUM to get the best results?

For maximum effectiveness, patients should use BIOCORNEUM consistently for the duration of treatment you advise. Recommended minimum treatment time:

  • new scars: 60 days
  • older scars: 90 days

How should BIOCORNEUM be applied?

  • Ensure that the affected area is clean and dry.
  • Apply a very thin, even layer two times a day (morning and evening) over the scar area.
  • BIOCORNEUM is quick-drying. Allow to dry completely.
  • Once dry, BIOCORNEUM can be covered with pressure garments, clothing or cosmetics.
  • If the affected area is subject to abrasion, it may be beneficial to repeat the application midday.
  • Wait 15 minutes before sun exposure.

For maximum effectiveness, BIOCORNEUM should have 24-hour contact with the scar area for the duration of the treatment.
