Crepidiastrum Denticulatum Extract (Pollux CD) in Skin Care

Crepidiastrum Denticulatum Extract is a plant derived antiaging cosmeceutical ingredient that has shown to protect the skin from the effects of air pollution. It is also called Pollux CD.


It is found in antiaging wrinkle creams, especially those meant to protect skin from pollution and increase autophagy.


Crepidastrum Denticulatum plant used in skin care

Plant derived natural ingredient

Crepidiastrum Denticulatum is a plant native to parts of Asia, including Korea and China. It grows in mountainous regions. The leaves and stems of the plant are used to make the extract. It is a natural ingredient that may be considered organic if grown following organic farming standards.

Diet

It has been in the diet of Koreans for many years.  The young leaves are consumed as a vegetable.

Topical Use

This water soluble plant derived ingredient is found in antiaging creams.

Skin Care Products

This is one of the most exciting new antiaging ingredients in 2023 and it is so new that it is not in very many products yet. We will continue to add products here as they come out. These are the medical grade brands that have Pollux CD:

Benefits

With its unique cellular effects, Crepidiastrum Denticulatum Extract offers several benefits for skin.  These benefits make it a great antiaging cream to begin in your 20s and 30s to help protect your skin.

  • Anti-aging: By stimulating autophagy and protecting against free radicals, it can help prevent signs of aging like wrinkles and dark spots.

  • Anti-inflammatory: Research showed it decreases inflammatory chemicals like interleukin-6, reducing redness and irritation.

  • Pollution protection: It shields skin cells from toxins found in urban pollution like cigarette smoke and heavy metals. This prevents damage from environmental factors.

  • Antioxidant: Its natural plant compounds scavenge free radicals, supporting the skin's defense system.

The antioxidant and has anti-inflammatory activity are the reasons this is an exciting new antiaging skin care ingredient. It helps treat and prevent aging because it:



The unique tissue-regenerating and protective effects of Crepidiastrum Denticulatum Extract make it an intriguing ingredient for anti-aging and anti-pollution skin care products. Its plant-based compounds work at the cellular level to promote youthful, healthy skin.

 

  • It activates autophagy, the cell's natural garbage disposal. This clears out toxins and damage that accumulate over time.
  • It limits inflammation by reducing inflammatory proteins like COX-2. This calms irritation.
  • It protects fibroblasts and keratinocytes from pollution-related chemicals like heavy metals and PAHs. This prevents toxicity from urban environments.
  • It acts as an antioxidant to neutralize free radicals from UV exposure and other stressors. This prevents oxidative damage.

Chemistry

The key active compounds in Crepidiastrum denticulatum extract are flavonoids and other polyphenols. 

Specific flavonoids found in the extract include quercetin, kaempferol, luteolin, and apigenin. These flavonoids have antioxidant and anti-inflammatory effects in the skin. 

In addition to flavonoids, the extract contains phenolic acids like chlorogenic acid and caffeic acid. It also provides sesquiterpene lactones which are anti-microbial. The combination of flavonoids, phenolic acids, and sesquiterpenes give Crepidiastrum denticulatum extract well-rounded active properties to benefit aging or at risk skin.

Safety

The EWG and CIR have not examined any safety data on this ingredient when used topially.


 It has been used in studies to show it can protect the liver from alcohol damage and the kidneys from reperfusion injury.  These all suggest that this ingredient is safe. 

Research Studies

A recent study published in the International Journal of Molecular Sciences (2) looked at how Crepidiastrum Denticulatum Extract works on skin cells. The researchers found that it increased autophagy in fibroblasts, which are cells in the dermis. It also protected the fibroblasts from damage caused by pollution chemicals. And it decreased inflammation in keratinocytes, which are cells in the epidermis.

Autophagy:

 In this study, they screened the autophagic activators from various plant extracts of family Compositae. Among them, CD extract showed increased the LC3 protein synthesis and LC3 cleavage with activating the phosphorylation of AMPK and beclin1 that are critical components in the regulation of autophagy.

Pollution protection:

It is known that pyrene and benzopyrene(BaP), which are poly-aromatic hydrocarbons(PAH), have the highest carcinogenicity and toxicity among the environmental pollutants. The treatment of CD extract recovered cell viability from BaP-induced cytotoxicity. In particular, the improvement of cell recovery was found to be superior than that of resveratrol, a typical autophagic activator.
