Because a bright and radiant smile holds power. And it is through a smile that beauty is seen.
IU’s beauty secret
Everyone knows K-Beauty. From glass skin to gradient lips and more, boys and girls have been raving over these trends. But one of Korean’s best-kept beauty secrets has always been their bright smiles. It’s a universal charm point that ignites connections, even between strangers. And for those in the limelight, a smile is what invites people in, building an emotional foundation for an unbreakable fandom. IU is the epitome of this.
The truth is, beauty is seen and welcomed with a smile. It brings “I” and “You” together. Simple as it may be, that’s the heart behind IU’s timeless appeal. Her beaming cheer, contagious laugh, and friendly giggles—these all add up to her desirable spark. And guess what, you can own that too!
The power of a smile
So here’s the scoop: Did you know that what really draws people in is a bright smile? Call it cliché, but it’s cliché for a reason! If you spend hours every day perfecting your makeup, but you can’t even make that simple effort of directing a smile to someone–be it a friend or a stranger–then what’s all that effort for? Because in the end, beauty is also something that you give. It’s meant to radiate. It’s felt. It’s experienced. And it spreads with a smile.
The tea is, oral beauty is the next evolution of K-Beauty. Moving beyond glass lips, aegyo-sal, and color analysis, Korea is finally exposing their most important beauty hack, and that’s owning a radiant, confident smile.
Leading this charge is Colgate Optic White Purple Toothpaste. Launched in the Philippines last March 2024, it quickly became viral on social media, resulting in out-of-stocks left and right. With many beauty awards earned, Colgate Optic White Purple Toothpaste also rose to the #1 spot as the country’s best whitening toothpaste brand in drugstores.
Purple = Whiter Teeth

PURPLE? Why purple?
Let’s dive into Color Theory, which tackles color combinations using the color wheel. Yellow and purple are opposites on the color wheel; when merged, it appears white. For oral beauty, this means purple color-corrects yellow tones to appear white.* Purple brighteners work by depositing a sheer violet tint on the tooth surface, effectively cancelling out yellowish hues through optical illusion. Cool, right?
*For temporary efficacy, results may vary.
