How It Works

RengaLife launched in April 2018 as a multi-level marketing company selling dissolvable film strips marketed for smoking cessation, weight loss, and male sexual performance. Jason Cardiff served as CEO and his wife Eunjung Cardiff served as Marketing Director. Participants paid a mandatory autoship fee of $199.80 per month to remain eligible for commissions, meaning the scheme required continuous payment regardless of whether members were selling products to real customers.

The FTC found that the health claims attached to the film strips were false and unsubstantiated, according to the FTC's November 2018 complaint against Redwood Scientific Technologies, the parent company Cardiff controlled. The income opportunity attached to RengaLife was also built on unsubstantiated earnings claims, meaning the lifestyle and income representations used to recruit participants had no factual basis. Consumers were additionally subjected to unauthorized charges and unauthorized product shipments through a continuity billing program they had not meaningfully agreed to.

Redwood Scientific also operated abusive robocall telemarketing campaigns, according to the FTC's allegations. These campaigns drove consumers toward products and an income opportunity built on fabricated claims. The combination of fake health claims, fake income projections, unauthorized billing, and aggressive telemarketing represents a layered consumer fraud structure targeting people looking for health solutions and financial opportunity simultaneously.

When the FTC prevailed through default judgment in 2022, no monetary penalties were imposed because a 2021 US Supreme Court decision had limited the FTC's ability to seek financial restitution in federal court under the statute it had relied upon. That legal outcome meant victims received no court-ordered compensation despite the fraud being established by judgment. Cardiff subsequently faced separate criminal charges brought by the Department of Justice in 2023, a track that carries the potential for prison time and criminal fines rather than civil penalties.

Red Flags. What Victims Reported

• Mandatory monthly autoship fees required to qualify for any commissions, regardless of actual product sales
• Health claims for smoking cessation, weight loss, and sexual performance products found by the FTC to be false and unsubstantiated
• Income claims used to recruit members found by the FTC to be unsubstantiated
• Unauthorized charges and unauthorized product shipments billed to consumers without clear consent
• Robocall telemarketing campaigns used to drive recruitment and product sales
• FTC filed suit in November 2018, company collapsed shortly after launch, leaving participants holding worthless inventory and autoship obligations
• Operator Jason Cardiff was found by a federal court to have lied to the court and described as totally unbelievable
• Cardiff fled to Ireland in late 2024 after receiving court permission to travel three times over DOJ objections, declared a fugitive in February 2025
• Cardiff posted social media content showing luxury goods, golf trips, ski holidays, and a Bentley while listed as a wanted fugitive
• Extradition paperwork was delayed due to spelling errors in the US filing, indicating systemic coordination failures that prolonged victim uncertainty

Investigation Findings

Court filings and regulatory records reviewed by DefendMe analysts show a documented pattern of obstruction by Jason Cardiff stretching over several years. After a federal court entered default judgment against Cardiff and Redwood Scientific Technologies in 2022 following the FTC's 2018 lawsuit, Cardiff faced separate criminal fraud charges brought by the Department of Justice in 2023. As his criminal case proceeded toward trial, Cardiff requested and received court permission to travel to Ireland on three separate occasions, each time over the objection of DOJ prosecutors.

Before the third trip was granted on November 20, Cardiff's US attorney informed the court on November 18 that Cardiff would not be returning to the United States. Court filings indicate Cardiff had represented to the court that a gynaecologist had advised him not to travel, a claim DOJ attorneys later scrutinized. A federal court that had separately handled the FTC civil case had already found Cardiff and his wife to be, in the court's own language, totally unbelievable and to have lied to the court. That finding was made available to the criminal court before travel permissions were granted.

In February 2025, Cardiff was formally declared a fugitive. A US arrest warrant followed in March 2025. According to reporting by The Irish Times, a US extradition request was approved on May 1, 2026, and an Irish arrest warrant was issued on May 11, 2026. Cardiff was arrested at his home on Highfield Road in the Rathgar neighborhood of Dublin, described as a property valued at approximately three million euros, at 8am on June 18, 2026. He was brought before the Irish High Court and granted bail subject to conditions including surrender of his Irish passport, a geographic restriction to the Rathgar area, and an 11pm to 8am curfew. The Irish Times reported that Cardiff, in an interview conducted the day before his arrest, stated he believed the charges against him would soon be dropped and described the case as almost over.

Criminal Context and Enforcement Landscape

The criminal case against Jason Cardiff sits within a long-running federal enforcement effort. The FTC sued Redwood Scientific Technologies and Cardiff in November 2018 under the FTC Act, citing false advertising, unauthorized billing, abusive telemarketing, and pyramid scheme recruitment. A default judgment was entered in 2022. Although no monetary penalties followed due to a 2021 US Supreme Court ruling that limited the FTC's civil restitution authority, the judgment established the factual record of fraud. The DOJ then brought criminal charges against Cardiff in 2023 on multiple counts of fraud, a separate proceeding that can result in imprisonment and criminal financial penalties independent of the civil outcome.

Cardiff's flight to Ireland and subsequent fugitive status represent a pattern seen in large-scale MLM and consumer fraud prosecutions where operators attempt to exploit international borders to delay accountability. US-Ireland extradition is governed by a bilateral extradition treaty, and the Irish High Court is now the venue for determining whether Cardiff will be returned to the United States to stand trial. His next scheduled Irish court appearance, as reported by The Irish Times, is July 10, 2026. Similar extradition cases involving US fraud defendants held in common-law jurisdictions have taken months to years to resolve through the courts, meaning Cardiff's criminal trial in the US remains pending.

For consumers harmed by Redwood and RengaLife, the criminal proceedings do not automatically produce compensation. Victims who suffered unauthorized charges, product losses, or losses tied to the income scheme may have separate civil remedies depending on jurisdiction, applicable statutes of limitations, and documentary evidence preserved. The FTC's case established the fraudulent conduct as a matter of record, which can support individual or collective civil claims in appropriate legal forums.

What Victims Should Do Now

1. Stop any remaining payments or autoship charges linked to Redwood Scientific, RengaLife, or any affiliated entity immediately.
2. Preserve all evidence: bank statements showing unauthorized charges, product receipts, recruitment materials, income claim documents, emails, and text messages. Store copies in at least two separate locations.
3. Do not contact Jason Cardiff, Eunjung Cardiff, or any representative of Redwood or RengaLife. Any contact could complicate your legal position.
4. Do not pay any third party claiming they can recover your money for an upfront fee. Recovery fraud targeting victims of known FTC cases is common. Legitimate platforms do not demand payment before delivering results.
5. File a complaint with the FTC at reportfraud.ftc.gov and with your state attorney general. Reference the Redwood Scientific Technologies FTC case and the DOJ criminal case against Jason Cardiff.
6. If you suffered unauthorized credit card charges, contact your card issuer immediately and file a chargeback claim. Document the FTC judgment as supporting evidence.
7. Use DefendMe's criminal complaint tool to document your specific losses and connect with resources that can help you understand your options under current law.
