WellStar founder and CEO Christian Wiesner reportedly promised affiliates annual bonuses totaling €44.5 million, according to internal company documents. Wiesner, who established the personal care MLM in 2004, claims over a decade of international networking experience and previously led a team of 120,000 customers in Europe.

The company's operational history is marked by significant disputes. In 2015, top affiliate Kari Wahlroos departed WellStar, initiating a public feud. WellStar accused Wahlroos of criminal activity, while Wahlroos countered that the company failed to deliver on its promises and suffered from persistent "endless problems." He alleged that when he raised these issues with Wiesner, his only suggestion was to "recruit more" affiliates. Wahlroos later promoted OneCoin, a scheme later identified as a Ponzi.

According to Wahlroos, WellStar's business model is plagued by product flaws and a non-functional returns system. He also cited a lack of customer support and poor partner assistance. Wahlroos stated that many leaders left WellStar due to inadequate earnings, forcing the company to launch new markets every three months to sustain itself. A primary concern for leaders, including Wahlroos, was the consistent delay and inaccuracy in commission payments. He asserted that the "fast start" recruitment focus of the WellStar plan prevented most affiliates from earning money. Wiesner dismissed Wahlroos's accusations as baseless.

WellStar operates within the personal care sector, marketing cosmetic products. Their product line includes the BYAS Face Lifter, BYAS MOVE MST Eye Lifter, and BYAS Body Lifter, all described as high-tech skin rejuvenation or body-forming systems for home use. Retail pricing for these items is not publicly available on the WellStar website.

The company's compensation plan, though presented with diagrams and definitions, is poorly explained. It appears to function on a unilevel structure with additional performance-based bonuses. The plan outlines fifteen distinct affiliate ranks. Qualification for the lowest rank, Vice-President, requires generating 0.6 PV monthly through personal purchases, autoship, or retail sales. The Trainee rank necessitates maintaining 0.6 PV monthly and recruiting at least two new Vice-President affiliates, with each of these legs needing to generate a minimum of 5 GV per month. The Junior Manager rank has similar PV requirements and involves maintaining two downline Vice-Presidents.

Wahlroos, who later passed away in Malaysia, had been a prominent figure in the network marketing industry. His association with OneCoin, a notorious cryptocurrency scam, further complicated his business narrative. The issues raised by Wahlroos regarding WellStar’s financial practices and operational shortcomings echo common criticisms leveled against recruitment-heavy MLM schemes.
