Colgate Optic White® Partners with Tsim Sha Tsui Cafe to Launch "Dental-Grade Teeth Whitening Lab"

Canto-pop Star Kaho Hung Joins as "One-Day Store Manager" to Champion the Aesthetic of "Drink Boldly, Smile Brightly"

Unlock the Secret to a "Zero-Distance" Dental-Grade Bright Smile with Hydrogen Peroxide (HP) - Hong Kong Dentists' Most Preferred Whitening Ingredient^{^}

HONG KONG, April 9, 2026 /PRNewswire/ -- For the modern urbanite who values quality of life, coffee is more than just a beverage; it is the ritualistic start to a quality lifestyle. Whether it is a rejuvenating morning black coffee or an afternoon latte with friends, coffee moments are essential for "charging" one's day. However, for coffee lovers, the lingering concern of dark, stubborn extrinsic stains and teeth yellowness often dims the experience. As the authority in professional teeth whitening, Colgate Optic White^®—Hong Kong's No.1 Whitening Toothpaste Brand^{^^}—is proud to unveil the secret to a professional-grade bright smile. Optic White^® Whitening Toothpaste Series is formulated with Hydrogen Peroxide (HP), Hong Kong Dentists' Most Preferred Whitening Ingredient^{^}. Unlike traditional toothpastes that only tackle surface stains, HP penetrates deep into the enamel to break down years of dark, stubborn extrinsic stains from the inside out, while creating a long-lasting protective barrier against new stains. By simply integrating this into a daily oral care routine, coffee enthusiasts can indulge in their favorite brews without compromise, showcasing a confident, bright and "zero-distance" smile.

From 11^th April to 11^th May, 2026, Colgate is breaking boundaries by transforming the popular Tsim Sha Tsui cafe, HOW to Live Well, into Colgate Optic White^® Dental-Grade Teeth Whitening Lab. This immersive pop-up aims to educate the public on the science of professional teeth whitening, revealing why Hydrogen Peroxide (HP) is the gold standard for achieving a dental-grade transformation. Adding to the excitement, Colgate has invited sensational Canto-pop singer and fan-favorite "Dean," Kaho Hung, to make a special appearance as the "One-Day Store Manager" on 18^th April, 2026. Known for his signature "zero-distance" bright smile, Kaho will lead guests through a sensory journey of coffee and professional whitening excellence, sharing how he maintains a camera-ready, bright smile amidst his hectic schedule using this dentist-preferred whitening solution.

"Drink Boldly, Smile Brightly": Master the Art of Coffee Living with the Hong Kong Dentists' Most Preferred Whitening Ingredient^{^} - Hydrogen Peroxide (HP)

For a connoisseur like Kaho Hung, coffee and a bright smile are the ultimate lifestyle duo. During the event, Kaho will personally craft the Colgate Optic White^® signature special (White Cloud Apple Jasmine Brew)—a bespoke coffee featuring cocoa-dusted Optic White^® motifs on creamy foam in Dental-Grade Teeth Whitening Lab. To elevate the experience, the drink is served with a creative Minty Cream "toothpaste tube", allowing shoppers to simulate the Colgate Optic White^® whitening process by adding their own minty cream to their coffee. This aesthetic experiment embodies Kaho's lifestyle motto: "Drink Boldly, Smile Brightly"—a reminder that with the right professional care —Colgate Optic White^® and its Hong Kong Dentists' Most Preferred Whitening Ingredient^{^}—Hydrogen Peroxide (HP), you never have to choose between your passion for coffee and a bright smile.

Limited Time Only! An Immersive Journey Where Specialty Coffee Meets Professional Teeth Whitening

Every detail, from the minimalist decor to the curated displays, reflects Colgate's professional authority and reinforces the professional reliability of Hydrogen Peroxide (HP), the Hong Kong Dentists' Most Preferred Whitening Ingredient^{^}.

Visitors can interact with a specially designed "Smile Phone" installation. Equipped with a high-definition camera, the device allows fans to capture their own Kaho-inspired bright smiles. Visitors can also record heartfelt voice messages for the "Dean" himself, creating a warm, interactive and personalized connection within this professional-yet-inviting space.
