The certification PAOT Technologies® is based on two different methods :
PAOT Skin® offers an in vivo analysis: that is, a product testing on volunteers.
An electrode will be placed directly on a body portion of the volunteer to analyze the antioxidant power of the tested product.
This technology is far more accurate than the PAO Liquid® ;due to the in vivo analysis it offers, PAOT Skin® labelling is more difficult to obtain.
This labelling will be more suitable for cosmetics, but may also be achieved by the food and nutraceutical industries.
PAOT Skin® labelling include three labels :
Gold PAOT® Silver PAOT® Bronze PAOT®
PAOT Liquid® provides an in vitro analysis: the measurement is made in a liquid medium, by dissolving the product in a reaction medium.
This technology is more suitable for food and nutraceutical industries.
For a PAOT Liquid® labelling, a different label is given: it is 5 hexagons, which will be filled based on the antioxidant power of the product which will be affixed on the label.
