Why Tannic Acid is important for skincare

TANNIC ACID [also known as Tannins] are polyphenolic compounds widely distributed in the plant kingdom and are believed to provide in plants a chemical defense against predators and ultraviolet radiation. They are classifieded into two major categories:

  1. Hydrolysable Tannins (HTs) which include gallotannins and ellagotannins,
  2. Condensed Tannins (CTs), proanthocyanidins. 

These plant polyphenols are potent antioxidants that may protect against free radical damage caused by exposure to UV light and, in turn, reduce the risk of skin cancer and premature aging. 

Tannins are found commonly in the bark of trees, wood, leaves, buds, stems, fruits, seeds and roots. In all of these plant structures, tannins help to protect the individual plant species. Tannins that become stored in the bark of trees protect the tree from being infected by bacteria or fungi. In this case, the tannins precipitate out the enzymes and other protein exudates from bacteria and fungi thus not allowing these organisms to infect the tree. Many bud scales on woody plants contain tannins to protect the inner leaf tissue from being consumed and in many seed plants, the initial set of leaves from a germinating seed is also high in tannins.

the importance of polyphenols for healthy skin

Flavonoids are widely distributed plant pigments and tannins occurring in barks, roots, leaves, flowers, and fruits. Their roles in plants include photoprotection and contributing to the plant color. Flavonoids also referred to as “plant polyphenols,” have been recognized as potent antioxidants. Their free radical-scavenging and metal-chelating activities have been extensively studied. By direct protein interaction, condensed tannins have shown to protect collagen and elastin against degradation, these are two important dermal matrix proteins in the dermis that form a mesh-like layer providing flexibility, stretch and strength to your skin.


Astringent Properties: Tannins owing to protein precipitation have a constricted and protective effect on the skin, therefore reducing the appearance of pores.

Soothes inflammation: Phytosterols reduce redness, inflammation and helps to soothe itchy skin.

Photoprotection: Tannins have significant anti-inflammatory effects on the skin response induced by UV-B [is primarily associated with sunburn].

Antifungal: Condensed tannins have been shown to have moderate antifungal activity against Candida species which causes fungal infection.

Absorption: The astringent properties of botanical oil high in tannins, provide a  less 'oily' skin feel and absorb more readily into the skin.

Until next time

Hello Bronte
Thank you for reading the Blog. You will be happy to learn we have incorporated a plant based ingredient which has the same effects as a Retinol without any of the skin down time associated with Retinol. It will not cause increased photosensitivity associated with Vitamin A retinoids – so a massive win for our skin! This ingredient has undergone clinical trials and has been proven to reduce the appearance of fine lines and wrinkles, even out the skin tone, regulate sebum and reduce inflammation.

sounds amazing and looking forward to trying the product. I am using Retin A product but concerned about getting enough sun protection and then all the nasty ingredients in sun cream.

When are you launching your face oil? I am a busy working mum and I just do not have time for complicated skin care routines, I need minimal products which are multi-taking! must be organic, H&KO tick my boxes from reading your blog posts. Loving the sound of tannic acid and what it can do for the skin.
