Description
With nutrient delivery options of patches, gels, creams and more on the rise, the promise of absorption via the skin is being sold as simple and seamless—but is it really? This episode unpacks the difficult path nutrients must take to initially enter the epidermis and then (more difficult yet) make it out the other side and to the rest of the body. Rachel identifies which essential vitamins & minerals as well as nutraceuticals, in their natural state, are ‘permitted passage’. In addition to this she describes exactly the nature and number of modifications necessary for others to circumvent the skin’s barrier function. Under the Cosmeceutical category, and subject to even less regulation than our breakfast cereal, claims of ‘transdermal delivery’ (having actions beneath & beyond the skin) are being applied to products whose effects may be strictly skin-deep.
