How ROSYFOXY Became Singapore’s Number One Best Selling Serum on TikTok Through Science and Real Results

ROSYFOXY, the London based skincare brand founded by Malaysian entrepreneur Lee Bin Hao, has quickly emerged as a rising star in the modern beauty world. Within its first year, the brand achieved a remarkable milestone, becoming the Number One best selling serum on TikTok Shop Singapore, driven entirely by genuine customer reviews and organic word of mouth.

While many beauty brands depend on heavy advertising and marketing, ROSYFOXY grew by focusing on science, transparency and real results.

A Global Skincare Brand Built on Collaboration and Biotechnology

ROSYFOXY positions itself as a global house of innovation built through strong scientific collaborations with leading European and Korean laboratories. Its signature Rosa serum contains the premium ingredient known as Rose Stem Cell, developed through advanced biotechnology by INNOVA BM Ltd in Bulgaria, and is formulated and manufactured in South Korea by HANACOS Co. Ltd, one of the industry’s most respected world class facilities.

“We’ve always believed that skincare should be powered by science and trusted by customers, not by marketing hype,” said Founder Lee Bin Hao. “Our serum’s success on TikTok Singapore is a reflection of the visible, real results customers experience. Transparency and authenticity are the heart of everything we do.”

A Scientifically Backed Skincare Revolution

At the core of ROSYFOXY’s serum is its signature Rose Stem Cell premium ingredient, a breakthrough known for supporting skin repair, regeneration and long term skin health. It is also rich in Exosomes, which help enhance skin renewal, brightness and texture.

The serum’s key ingredients are COSMOS approved, reflecting its dedication to safe, sustainable and high-quality formulations.

All formulations undergo strict stability testing, safety checks and R&D development through collaborations with European biotechnology laboratories and South Korea’s leading formulators. Every product is designed to deliver visible improvements within fourteen days, and to comply with the global regulatory standards of the United Kingdom, Singapore, Malaysia, Thailand and Vietnam.

A Global Footprint and Skincare Success Across Asia

From its headquarters in London, ROSYFOXY has expanded rapidly across key international markets including the United Kingdom, the United Arab Emirates, Singapore, Thailand, Taiwan, Vietnam and Malaysia. The brand is steadily growing throughout Asia and the Middle East, fuelled by its commitment to transparency and advanced biotechnology.

ROSYFOXY’s success on TikTok Singapore placed the brand firmly in the spotlight and attracted customers who value science backed formulas, honest communication and clear product origins.

The Power of Customer Trust and Word-of-Mouth

Unlike brands that rely on large marketing budgets, ROSYFOXY’s rise has been fueled by authentic customer experiences. The serum has generated thousands of genuine before and after results, with customers actively sharing their transformations on TikTok.

Customer testimonials speak for themselves:

”My 3rd repeat order. Finished 1 bottle in a week. Skin texture smoothen, complexion is more radiant. Pigmentation lightened, fine lines & neck lines visibly reduced within a week. A must use serum in my daily skincare routine.”

“I've been using this amazing Rosa serum for the past 7 months. Not only my pigmentation lightened, fine lines reduced, face is also more radiant & smooth. I now replaced hand cream with Rosa serum. My hands are no longer dry & look like old lady anymore. Picture speaks more than thousands words”

“Pigmentation n brightening the skin. Bought the triple pack for family member. It's easy n simple step that one bottle of the serum settle everything Hopefully the prices of ROSA maintain affordable so that more ppl can beneficial”

These honest results are the foundation of ROSYFOXY’s growth.

Overcoming Obstacles – A Founder’s Determination

There was a moment when the journey felt overwhelming, especially when Lee realised how difficult it is to build a skincare brand rooted in real science and full transparency.

Finding a truly world-class Korean manufacturer was one of the biggest obstacles. The Korean beauty industry has many factories, yet only a small number meet the highest global standards. It took years of evaluation before ROSYFOXY finally selected its manufacturing partner, choosing quality over convenience.

Finding the world’s best ingredients was equally challenging. After years of research, Lee discovered advanced Rose Stem Cell biotechnology in Bulgaria. He describes the process like cooking:
The manufacturer and R&D team are the master chefs, and the Rose Stem Cell is the premium ingredient. Both must work perfectly together to create an exceptional formula.

To ensure complete confidence, Lee personally flew to South Korea and Bulgaria, visiting laboratories and manufacturing facilities himself, documenting the entire process with real video proof.
This became a turning point in his journey. It reaffirmed that building with honesty and scientific integrity is difficult, but worth it.

ROSYFOXY’s Vision for the Future

Looking ahead, ROSYFOXY aims to expand even further across Asia and the Middle East while continuing to collaborate with the world’s top scientists and biotechnologists. The brand will maintain its commitment to transparent communication, advanced research, and high-quality formulations.

“We believe the future of beauty is built on science, integrity and customer trust,” said Lee. “Our goal is to keep delivering high performance skincare at honest prices, and to become a global skincare house recognised for real results.”
