The Radiance Powder is safe to take with other supplements.

However for best results and if it is your first time taking the Radiance Powder, we recommend pausing all other voluntary supplement use for the first 30 day, in order for the Radiance Powder to have the best effect on your body long term.

We recommend taking the Radiance Powder on an empty stomach for best results and to limit exposure to digestive enzymes and bile salts. 

We recommend adding the Reforming Liquid to water and drinking on an empty stomach, with or ideally after food consumption.

However, you know your body best—if either is more comfortable for you to take with or without food, please feel free.

Nothing with the Reforming Liquid and Universal serum.

There’s no harm if you miss a day on your first jar of the Radiance Powder also, or even if you miss a few. But for optimal results, daily intake is encouraged. This is because our Powder is created to reach and keep its potency by the time it gets to your colon (where the majority of your microbiome resides) to activate systemic benefits through programmed interactions with your existing bacteria and your body. This is why continuous intake is important—it’s the clinically-studied dosage to optimise for the most impact.

It’s safe to take more than the recommended dosage, though there is not necessarily any added benefit to do so.

It is not necessary to do so as the jars our products come in have a patent which protects the product from UVA and UVB light, and keeps the formulation stable.

Radiance Powder

A 6-in-1 clinically and dermatologically studied supplement formulated to improve overall skin health from the inside, out.

The Radiance Powder benefits go beyond just skin health. You can read more on the Shop page about the digestive, gut barrier function and immune health benefits it has also.

The Radiance Powder should be taken continuously until the whole jar is finished. Once a day, either mornings or evenings on an empty stomach. Try not to miss a day, but if you do just start up again as soon as possible.Once you have finished the first jar you can wind down the dosage and usage depending on what your skin needs and how it reacts. 

There is no harm in taking the Powder every day continuously, however it was formulated to ‘reset’ skin from within in 30 days and then be used after as a skin treatment from within whenever you need a booster and to get back on track.

We recommend seeing how skin feels after 30 days. If your internal dysfunction is severe, you are struggling with irritations and reactions you can’t get to the bottom of, continue use alongside adopting new lifestyle changes to suit your skin’s needs and taking the relevant tests to determine what might be the root cause of your breakouts and skin’s inflammatory response.

Our whole team now takes it a week before their period to calm hormonal acne, when they are particularly stressed or haven't eaten well as a digestive relief and aid. It is not necessary to take daily after the first jar but a great tool to have on hand to support your skin in becoming and staying permanently clear and healthy.

Universal Serum

The Universal Serum is an active topical facial serum to be applied to the whole face or specific areas of irritation, daily. We used enzymes to manipulate the molecular structure of the ingredients within so it acts as a topical treatment, sinking deeper into cell structures than conventional serums for longer lasting results.

We recommend applying the serum to skin daily. It is a step in all of our skincare routines that we do not miss. Most of the ingredients within are found naturally in skin and cell structures so are literally supplementing back in daily what is lost with age, stress and depleted by external toxins and pollutants. Your skin will thank you for sticking to this Serum as a base product long term.
