at the beginning
Dr. Louie Kim’s work on self-preservation began early in his career at a pharmaceutical company, where he was looking for a way to replace the preservatives used in baby powder.
He found that alpha-bisabolol, the main active component of German chamomile, strengthens the antimicrobial activity of other ingredients with preservative-like properties.
That discovery led to a Korean patent registered under the company’s name in 1994 (Korean Patent No. 71457), and it was the start of a long journey.
PROGRESS
A few years later, he took his research further with a vegetable wash made entirely from edible ingredients (Korean Patent No. 112139, registered 1997). He even drank a cup of it to prove it was edible!
He went on to apply the same approach to other personal care products, including a deodorant stick (US patent application US 2005/0089488).
He eventually brought this work together into a complete self-preservation system (US patent application US 2006/0257347).
DrLOUIE Today
When he started his own brand, DrLOUIE, he developed an advanced version of this system. It adjusts the formula’s water activity and relies on the synergy of bisabolol and other ingredients with preservative functions to keep microbial growth in check.
The result: products made without conventional preservatives like parabens and phenoxyethanol, which stay fresh while staying gentle on your skin.
