The accidental beauty mogul: Catherine Tan and the story of Crystal Tomato

“Nobody had done it,” Tan says of turning this research into a supplement. The scientists were thinking of just a product perhaps for cosmetics.

She thought: “Since it's a tomato, I’m sure you can eat it.”

Her pragmatic logic led to international negotiations, two years of exclusivity rights, and the beginning of what would become Crystal Tomato.

The manufacturing moved to the United States while the tomatoes remained with their original cultivators, a decision driven by regulatory considerations for Asian expansion. The exclusivity wasn’t just contractual—it was practical. The scientists had spent over 10 years studying and researching this natural plant variety.

The credibility gap

Launching Crystal Tomato in Singapore presented immediate challenges. Tan had no beauty industry credentials, no medical background, and a product name she’d coined herself. “There [was] a doctor who said ‘I searched the whole night for Crystal Tomato and I couldn’t find it on Google.’ [I thought], ‘Of course you can’t, because it’s a brand I coined.’”

Her strategy was audacious: bypass retail entirely and go straight to doctors. “From day one, I wanted it to go to the doctors.” This wasn’t just about prestige—it was about credibility in a field where medical validation matters. But doctors were sceptical, understandably so. Their body language and attitude suggested they were tired of meeting people making unsubstantiated claims.

The breakthrough came through what she describes as a “really, really dangerous” decision: requesting the National Skin Centre conduct clinical trials. “If it turned out with no good results, then my brand would be over the next day,” Tan declared.

The process lasted more than 18 months, involving ethical board approvals, Health Science Authority clearance, patient recruitment, and months of testing. During this period, the product was already selling well, prompting some doctors to suggest she abandon the study. Her response was characteristically direct: she couldn’t sleep well if the product didn’t work and wanted to find out for herself.

The trials exceeded expectations, demonstrating up to 50 per cent improvement in melasma in just 84 days, validating both the product’s efficacy and Tan’s conviction that evidence should precede marketing, not follow it.

This commitment to clinical proof over celebrity endorsement remains central to Crystal Tomato’s identity. “I don’t believe in using stars, using celebrities, to endorse my product,” Tan states firmly. “I would rather invest my money in the clinical trial, proving that the product really work and then it does give results in the long term. And more importantly is safe.”

Her approach extends to claims themselves. Where the sunscreen tests showed higher protection levels, Crystal Tomato claims conservative figures. This practice has earned her recognition as someone who maintains integrity in an industry prone to overstatement. She added: “At this age and time, I don’t want to do something like that. It’s really my reputation.”

Crystal Tomato’s expansion beyond supplements demonstrates Tan’s patience with research and development. The Beyond Sun Protection sunscreen, launched after five solid years of development, began with her attendance at a 2014 dermatological conference where she first learned about blue light damage.

The speaker discussed how blue light was discovered to be potentially more damaging than UVA and UVB rays. The challenge was creating a product with very high protection that wasn’t heavy or greasy—a seemingly impossible combination since high protection typically requires multiple filters that are naturally heavy and greasy.

She worked with laboratories across different countries before settling on a formulation completed in Singapore. The testing was equally rigorous, involving laboratories around the world because so few facilities could measure blue light protection. The final product achieved an impressive SPF 79+ and PA++++ rating, with clinical studies showing 54.1 per cent superior blue light absorption rate and 87 per cent of users seeing significant improvements in skin texture.

This methodical approach makes Crystal Tomato’s National Day Parade sponsorship all the more remarkable. When her team proposed sponsoring sunscreen samples for the 216,000 attendees, Tan’s initial reaction was: “Are you joking?”

But the logic was sound. After years of B2B sales through doctors, direct consumer engagement made strategic sense. The NDP organisers were enthusiastic—sunscreen was both practical and unprecedented. But the timeline was punishing. Crystal Tomato produces fresh batches rather than drawing from warehouse stock, meaning 216,000 units had to be manufactured specifically for NDP.

The real crisis came when Tan realised the tiny tubes would disappear in the goody bags. Last-minute sleeves had to be designed and printed, adding significant cost. The packing became a community effort—there were between almost 30 people from within Tan’s circle, from bankers to doctors on top of staff members who all put on hairnets and hand-packed products in Crystal Tomato’s facility.

“My whole office stopped work and just did that … we were all just doing manual packing,” Tan remembers. Despite missing the original deadline, the NDP organisers accommodated the delay. The investment was substantial, but Tan viewed it as giving back to Singapore. 

Tan’s investment in skincare isn’t purely business. She shows photos from 2011 revealing severe melasma that transformed over eight months using her own products. The dramatic improvement came without lasers, which she believes worsen pigmentation by triggering protective responses. Her daily routine centres on the clarity cream she developed, applied morning and night with extra attention to pigmented areas. But her most emphatic advice is simpler: “You can skip any product but never miss your sunblock.”

At 16 years old, Crystal Tomato spans around 20 countries, primarily across Asia and Southeast Asia where pigmentation concerns create natural demand. The brand is now trusted by over 3,000 dermatology clinics worldwide and available at major medical institutions like National Skin Centre and Tan Tock Seng Hospital, as well as retailers including Tangs, Robinsons, and online platforms.

Future products remain in development, following the same lengthy R&D cycle that characterises all Crystal Tomato launches. The company takes a “very long time for R&D”, Tan acknowledges, refusing to launch products unless they can be medically proven to work. The skincare focus continues, having covered internal supplementation, topical treatment, and protection through their curated range of signature formulations.

Tan’s team reflects her commitment to long-term thinking. Some employees have worked with her for over 20 years, with others having been with her for over 40 years. “We have got a very good team that I can actually leave [to themselves]," she says, crediting their support for her ability to maintain a healthy work-life balance.

Her advice for aspiring beauty entrepreneurs? Focus on product efficacy rather than being savvy in marketing. Finding a product that actually works is the real challenge, she emphasises. Integrity is paramount—making claims that aren’t true will eventually backfire.

The approach requires patience and substantial investment in research, but Tan’s long view extends beyond immediate returns. Her passion for the work is driven by reputation and personal conviction.

When asked about success after over a decade, her response is typically measured: “I wouldn't call it success. There’s still a long way to go.” The initial goal was doctor acceptance and understanding. Now it’s geographical expansion and continued innovation within the rigorous framework she’s established.

Tan’s journey from paper trading to pioneering oral skincare supplements illustrates how second careers can become defining ones. Her insistence on clinical validation over celebrity endorsement, conservative claims over aggressive marketing, and patient development over quick launches has created a brand that stands apart in an industry often criticised for style over substance.

Plus, the National Day sponsorship represents more than marketing—it’s a gesture from someone grateful for the opportunities Singapore provided. At an age when most entrepreneurs have either sold their companies or stepped back from daily operations, Tan remains actively involved in product development, proving that in beauty as in life, the most enduring success often comes to those patient enough to build it properly from the ground up.
