Cultivating Beauty
from Within

Beauty is more than skin deep – it starts from within. Having a healthy gut microbiome could be the key to healthy glowing skin. Our probiotic elixir is expertly curated to protect the health of your gut and restore your skin’s natural radiance.

Our antioxidant-rich strains naturally produce carotenoids and Riboflavin (Vitamin B2) in the gut, where they are immediately absorbed for maximum effect. While antioxidants from food and supplements do not survive the digestive system well, our strains have the ability to withstand stomach acid making them one of the most bioavailable and potent supplementary antioxidants.

Bacteria with benefits


Bacillus pumilus produces Riboflavin (vitamin B2), essential for maintaining the growth of tissue to promote healthy cell turnover for a bright, radiant complexion.

Helps restore skin hydration.

Helps to prevent dry, cracked skin caused by Riboflavin deficiency.

Skin Tone

Bacillus indicus produces carotenoids which guards the skin against premature sun damage.

Helps improve skin tone and prevent the formation of dark spots.


Riboflavin improves zinc and iron absorption, important minerals for acne-prone skin.

Helps maintain mucus secretion in the skin which inhibits acne-producing bacteria to prevent breakouts.


Riboflavin aids protection of the skin’s structural integrity to reduce inflammation and speed wound healing.

Bacillus subtilis has a unique ability to synthesis vitamin K2 which aids the skin’s healing process by supporting the skin’s natural barrier function.


Carotenoids and Riboflavin are among the most powerful antioxidants.

Helps protect the body against free radical damage (a consequence of exposure to sunlight) which can help to slow ageing.

Research and Development

Every one of our products is the result of extensive strain screening combining lab studies as well as in vivo. Each strain is DNA-verified and underwent thorough research before it was hand-picked for its specific targeted beneficial properties. All products are microbiologist-formulated in London and made in the UK.


The viability of probiotic bacteria is greatly impacted by the way in which it has been cultured which is why we only use bacteria that has been cultivated using a hypoallergenic, vegan, non-GMO growth medium. All bacteria is bio-fermented in pharmaceutical-grade facilities (conducted under cGMP and HACCP guidelines).


All of our products have undergone independent third-party testing to ensure correct dosage (defined as CFU) of probiotic bacteria and stability. Our products adhere to GMP guidelines throughout every step of the manufacturing process including the final product.

Facts & Questions

What is the gut-skin connection?

The skin is our largest organ and one of the major systems by which the body expels toxins and waste. This means the skin is often a good indicator of gut health and when our gut is out of balance, it can show up on your skin as spots, inflammation, eczema and rosacea. This link between the gut and skin is called the ‘GUT-SKIN AXIS’. 

Our probiotic strains are expertly curated to protect the health of your gut and restore your skin’s natural radiance.
