/R E P E A T -- Sirona Biochem Announces Launch of First Commercial Product Containing TFC-1067/

Sirona Biochem Corp . (TSXV: SBM) (FSE: ZSB) (US-OTC: SRBCF) is pleased to announce the launch of the first commercial product containing the Company's proprietary ingredient, TFC-1067. TFC-1067 will debut as the active ingredient in New Rodan + Fields REVERSE Targeted Dark Spot Corrector. It will precisely target stubborn discoloration for a brighter, even-looking skin tone.

Rodan + Fields licensed TFC-1067 from Sirona in 2019.

In Rodan + Fields clinical trials*, REVERSE Targeted Dark Spot Corrector had the following results:

• After 4 Weeks: 77% had less visible dark spots
• After 8 Weeks: 72% didn't feel like their dark spots were the first thing people noticed

Rodan + Fields additional claims:

• Diminishes the appearance of stubborn dark spots without leaving a halo
• Stubborn dark spots look smaller, less defined, less intense
• Skin tone looks more uniform and even
• Stubborn dark spots are less visible, less noticeable
• Skin looks clearer, more translucent

Sirona also recently partnered with a top-ten pharmaceutical company to conduct a European clinical trial to assess the efficacy of TFC-1067 at .4%. The 12-week study was completed successfully in February. Results are being consolidated into a final report to be released within the next few weeks.

"Rodan + Fields' use of TFC-1067 in their new REVERSE Targeted Dark Spot Corrector after extensive testing is the strongest validation of our technology to date. Rodan + Fields demand product excellence and innovation for their customers. TFC-1067 is the basis for a product that can uniquely brighten dark spots without leaving a halo effect," said Dr Howard Verrico , CEO of Sirona Biochem. "Our long-term goal is to provide an effective alternative to hydroquinone for those seeking a solution for skin discoloration. With this launch, we have proven that we can take a compound from the laboratory through clinical trials to large-scale production and integration into a commercial product. This validates our business model and we aim to follow the same path exactly for our entire pipeline. This transformative event is only the beginning as Sirona Biochem evolves into a profitable broadly diversified large company."
