PEOPLE, SUNLIGHT & CARE

BORN IN KOREA, SHAPED BY THE WORLD

Vision

Skincare that feels good, works hard, and fits into real routines.

Where it began

hansori was born from my life between Korea and Mexico, two places defined by bright sun, vibrant people, and busy days. After growing up in Latin America, studying in Mexico to become a dentist, I moved to Korea to conduct public health research.

In dentistry, brushing is a non-negotiable step in preventing long-term damage. The same framework applies to skin. True skincare starts with prevention, and sunscreen is the essential first step to protect your skin.

I believe healthy skin shouldn’t be complicated.

My promise is that hansori will always make sun care simple, effortless, and grounded in what truly matters: protecting your skin, every day.

Founder

The Solution

Everyone knows the frustration of traditional sunscreen: the stickiness, the stinging, the mess.

The 01 Sun Stick was created as a solution: a clean, natural, reef-safe formula powered by ingredients like licorice root that glide on silky smooth.

No stickiness, no stinging, no mess.

Just convenient, effortless skin health at your fingertips.

That is the spirit of

  • Hansori (한소리) means "one sound" in Korean — simple, strong, resonant (just like sun care should be!)

  • Yes! As the founder also has extremely sensitive skin, the 01 Sun Stick was formulated as a fragrance-free, lightweight sun stick with soothing ingredients chosen to minimize irritation. It’s made for everyday use, even for skin that reacts easily.

  • No. The 01 Sun Stick was developed to melt seamlessly into the skin with no white residue, making it ideal for all skin tones — designed for comfort and no extra fuss.
