Machine learning for the prediction of sunscreen sun protection factor and protection grade of UVA

Abstract

We report a prediction model for sunscreen sun protection factor (SPF) and protection grade of ultraviolet (UV) A (PA) based on machine learning. We illustrate with real clinical test results of UV protection ability of sunscreen for SPF and PA. With approximately 2200 individual clinical results for both SPF and PA level detection, individually, we were able to see that active ingredient information can provide accurate SPF and PA prediction rates through machine learning. Furthermore, we included four new factors—presence of pigment, concentration of pigment grade titanium dioxide, type of formulation and type of product—as additional information for the prediction model and were able to see increased prediction rates as results.

The Clean Beauty Trend Among Millennial and Generation Z Consumers: Assessing the Safety, Ethicality, and Sustainability Attributes of Cosmetic Products

“…Most commonly, regression analysis has been used to develop equations for prediction (Apaolaza-Iba´n˜ez et al, 2011). Furthermore, machine learning, a computational analysis of the complex relationships between parameters that cannot easily be interpreted by the human mind, has been used for various purposes in the cosmetic and skincare research fields for regression analyses or development of prediction models (Cho et al, 2022;Shim et al, 2019). Given the multitude of parameters, encompassing both quantitative and qualitative data, our belief was that machine learning would be the most effective approach for developing RCS.…”
