Mexoryl: Broad-Spectrum Ultraviolet a Photoprotection
Bibliographic record
Abstract
The deleterious effects of long-wave (320–400 nm) ultraviolet (UV) radiation on human skin have been recognized for decades. Human exposure to UV radiation may induce skin pigmentation and sunburn, cutaneous connective tissue alterations (photoaging), immunosuppression, and the development of skin cancers. Public awareness campaigns on the need for photoprotection advocate the regular use of sunscreens. Consumer demand and an expanding knowledge of the adverse effects of UV exposure have fueled the continual development of novel sunscreen formulations. Two organic UV filters, terephthlylidene dicamphor sulphonic acid (Mexoryl SX, L'Oréal, Paris, France) and drometrizole trisiloxane (Mexoryl XL, L'Oréal), provide effective protection from UV irradiation and offer improved safety profiles in terms of protection from UVA radiation. This article details the photoprotective benefits of Mexoryl SX and Mexoryl XL.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
