The Clinical Pyramid

It has taken us over four years of research to develop the 28 Day Skin treatment method. Our innovative approach to tackling the entire acne forming chain is based on the science on the acne rather than trending ingredients and our patent pending combination of nutrition, technology and topicals is unique in the world of acne treatment.

Every element of the 28 Day Skin approach is supported by independent robust clinical evidence. The combination of topicals and blue light phototherapy was the center of a groundbreaking clinical study by our medical consultant Dr Caerwyn Ash. We call this body of scientific evidence our clinical pyramid.

Our research is ongoing however and we are currently recruiting for a large multi-center study commencing in January 2020 to investigate the efficacy of our neutroceutical one pill combined with our exfoliating serum, blue/red light phototherapy and our innovative second generation repair serum.
