The History of Whoo - Youth Guardian

At the heart of the Youth Guardian™ complex is the concentrated extract of “Irish Thistle“, officially known as Cirsium Japonicum and referred to as “Da Ji” (대계, 大薊) in Traditional Oriental Medicine.

In Oriental Medicine, Cirsium Japonicum has been traditionally used to cool the Blood, eliminate Blood stasis, relieve toxicity, and promote the healing of sores and swellings1.

Recent scientific studies have also highlighted the benefits of Cirsium Japonicum in combating skin aging and improving skin elasticity. Research shows that Cirsium Japonicum has a significant impact on skin glycation — a process that accelerates aging by causing sugar molecules to bind to proteins like collagen, resulting in stiffness, loss of elasticity, and wrinkles.

The primary active components of Cirsium Japonicum have been shown to combat glycation, thereby enhancing skin firmness and reducing the appearance of wrinkles2.

The efficacy of Youth Guardian™ is further enhanced by the use of an advanced low-temperature extraction technique that concentrates Cirsium Japonicum extract tenfold. This method preserves the integrity of the active compounds in the botanical extract, ensuring maximum potency and effectiveness.

Gong Jin Solution

Like all products from The History of Whoo, the “Jung Yuncho” line contains “Gong Jin Solution™”, also known as “Gongjinbidan” (공진비단, 供辰秘丹), a proprietary herbal complex that constitutes the core ingredient of the brand.

“Gong Jin Solution™” 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”3.

The History of Whoo - Gongjindan

“Gongjindan” appears in many traditional medical texts from China and Korea and it’s described as a remedy that strengthens the body’s immune defences and brings back the natural balance between its organs.

The Donguibogam (the most representative text of Traditional Korean Medicine) describes “Gongjindan” as follows:

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 science, LG Household & Health Care developed a cosmetic ingredient based on the original prescription for “Gongjindan”: “Gong Jin Solution™“.

Developed through The History of Whoo’s integrative medicine research technology, “Gong Jin Solution™” consists of:

1,2-Hexanediol, Angelica Gigas Root Extract, Arginine, Butylene Glycol, Cornus Officinalis Fruit Extract, Ethylhexylglycerin, Ganoderma Lucidum (Mushroom) Extract, Glutamic Acid, Glycoproteins, Thymus Vulgaris (Thyme) Extract, Water4.

In particular, the ingredient was enriched with four traditional herbal remedies:

  • Ganoderma Lucidum (영지버섯, 灵芝属), or “Ling Zhi”, is highly-regarded in Oriental Medicine for promoting health and longevity. The ingredient was first described in the Classic of the Materia Medica (also known as Shennong Bencaojing, 神農本草經) and it’s used to alleviate fatigue, strengthen the immune system, and promote overall well-being.
  • Angelica Gigas Nakai Root (참당귀뿌리, 当归), or “Dang Gui”, is known to replenish Qi and nourish Blood, meaning it restores vital energy levels and promote a healthy circulation of nutrients and energy across the body.
  • Cornus Officinalis Fruit (산수유열매, 山茱萸), or “Shan Zhu Yu”, is valued for its astringent and tonifying properties [T/N In Oriental Medicine “astringent” ingredients have the function of rebalancing the main vital substances that animate the human body: Essence, Body Fluids and Qi].
  • Thymus Vulgaris (Thyme) (타임, 百里香), which boasts antimicrobial and anti-inflammatory properties.

Overall, the ingredient promises to increase energy flow, while also rebalancing and reinvigorating skin to enhance the skin’s intrinsic energy and elasticity5.
