Skin Pharmacology and Physiology, 2004
The present work uses the initial step of the whole cascade of biological effects in the skin, the creation of free radicals by means of UVA/UVB radiation, to develop a total sun protection factor. Until now, existing in vivo indices have not been fully satisfying: SPF only reflects protection from UVB light, and persistent pigment darkening is ...

Correlation of in vivo and in vitro measurements of sun protection factor
Journal of Food and Drug Analysis, 2020In this study, the correlation of measuring sun protection factor (SPF) values between in vivo and in vitro tests was investigated for the purpose of monitoring the in vivo efficacy of sunscreen products using in vitro tests instead of in vivo tests to ...

Lip Sun Protection Factor of a Lipstick Sunscreen
Dermatology, 2001<i>Background and Objective: </i>There is a well-documented need for effective human UVA and UVB photoprotection. Since there are important anatomical variations, the sun protection factor (SPF) of a lipstick sunscreen was measured on the anatomical site intended for use. <i>Methods: </i>The SPF tests were performed according to

SynopsisThe absorption of ultraviolet light by a film of sunscreen product on the surface of the skin is considered from a theoretical standpoint. It is apparent that Beer‐Lambert's Law would predict protection factors in excess of the actual factors by many orders of magnitude.

Sunlight is important to health, but higher exposure to radiation causes early aging of the skin and skin damage that can lead to skin cancers. This study aimed at producing a stable octyl p-methoxycinnamate (OMC)–loaded nanostructured lipid carrier (NLC)

The perplexing dilemma of measuring sun protection factors
International Journal of Cosmetic Science, 2017AbstractTruth, like knowledge, is surprisingly difficult to define. Indeed, every definition of truth that philosophers have developed falls prey to the question, ‘Is it true?’ In this essay, we consider what is the true SPF of a sunscreen product and whether it can ever be realizable.
