The specific HelioScreen Labs response
An unpublished approach for the
evaluation of the physico-chemical equivalence of two products in terms
of absorption :
… therefore, in terms of global protection.
Based on an 18 months study of 3 different products, manufactured every month, and compared to their standard sample.
This is the only method which allows the true comparison of two sun protection products, escaping to the usual variation linked to the SPF or UVA PF evaluation. |
