King Di, originated from innovative technology from Britain in the 18th century. It is a brand under Haoyan Group (English abbreviation: finelab), focusing on the field of human oral health products.

The seven common oral problems in humans are tooth decay, gums, tooth sensitivity, tartar, plaque, breath, and unclean teeth. The modern pace of life has made many people ignore oral care. With the increasing scientific and mature concept of oral health, Diwang combines the essence of careful research and development of a century of human wisdom to inspire consumers to care for oral care and protect oral health.

In the 18th century, oral problems plagued many British families. Dr. Willen Addis's lover was also not spared. Seeing his lover's painful expression, Dr. Weilun felt extremely distressed. With concern and care for the lover, driven by the sincere heart of love, we have conducted many years of oral medical research.

At the Royal Medical Laboratory in the UK, Dr. Willen Atis discovered an active ingredient, including DNA globulin, HGH recombinant cytokines, whitening factors, purification and regulating and regulating cytokines, etc. This active ingredient has antibacterial, anti-inflammatory and anti-allergic effects.

The newly discovered active ingredients were successfully applied to oral care, which can slow down and treat bleeding gums, redness and swollen gums, bad breath, and dentin allergy.

In honor of Dr. Willen Addis' great research, the brand named after "DR.WLEN" was born in the UK and has been used to this day.
