The Bichup (비첩) line is The History of Whoo’s representative skincare line. It’s a complete anti-aging skincare treatment that works both preventively and correctively. The products in the Bichup line work together to enhance skin’s natural self-repairing power, reduce visible and underlying signs of aging, and improve overall skin immunity.
Disclaimer: I personally translated the majority of facts and contents in this article from original Korean sources, so I kindly ask you to credit my work if you’re planning to use any of the information included in this guide.
Many concepts mentioned in this guide are based on Oriental Medicine principles, for a better understanding please refer to the introduction to Traditional Korean Medicine on this website. It’s important to stress out that there is no correspondence between Oriental Medicine organs and Western anatomy so capitalised names in this article shouldn’t be interpreted in the Western medical sense.
The main products of the Bichup line don’t have many ingredients in common, rather they are developed as standalone products with complimentary effects that work in synergy to stimulate skin regeneration and boost circulation.
Like all products from The History of Whoo, the products in the Bichup range contain the brand’s signature ingredient Gongjibidan.
All products from The History of Whoo incorporate Gongjinbidan (공진비단, 供辰秘丹) a proprietary herbal complex that constitutes the core ingredient of the brand.
Gongjinbidan is based on Gongjindan (공진단, 拱辰丹), a traditional Oriental medicine prescription originally created by Chinese physician Wei Yilin. According to the classical text or Oriental Medicine “Efficacious Remedies of the Physicians” (세의득효방, 世醫得效方), Gongjindan was a remedy exclusively reserved for emperors and for this reason, it earned the name of “Emperor’s Medicine”4.
Gongjindan appears in many traditional medical texts from China and Korea and it’s described as a remedy that strengthens the body’s immune defenses and brings back the natural balance between its organs.
The Donguibogam (the most representative text of Traditional Korean Medicine) describes the Gongjindan as follows:
If a man is sickly even after growing up, he is constitutionally weak. In such a case, body fluids should be increased but body heat should be cooled down. Other medicines are inefficacious against it, but this medicine is effective to harmonize internal organs with each other and to prevent various diseases.
DONGUIBOGAM (1613)
To this day, Gongjindan is a vital tonic that is still commonly used in many Asian countries to combat chronic fatigue, weak constitution and deteriorated immunity.
Through the integration of modern dermatology, LG Household & Health Care developed a cosmetic ingredient based on the original prescription for Gongjindan: Gongjinbidan.
The Gongjinbidan Complex contains equal amounts of six precious herbal ingredients2, including:
Bichup First Moisture Anti-Aging Essence
Bichup Ja Yoon Cream
Bichup Moisture Anti-Aging Mask
