“Going back to sunscreen itself:
What is a sunscreen? I read the ingredients of three popular-brand sunscreens I have in my cabinet (all with an SPF of 30). There's no replication of any active chemical and two products don't list chemical concentration levels. Inactive ingredients cover a wide spectrum including but not limited to Glycol, Diazolidinyl Urea, Oat Beta Glucan, Propylaparaben etc. etc. etc.
To the best of my knowledge, study findings haven't been reproducible; science has yet to identify and standardize a specific or group of active chemicals that do in fact offer UV light protection/buffering.
Meanwhile the " Sunscreen and Skin Protection" aisle at the Duane Reade store near me keeps growing and growing...”

“Did the research cite any subsets within the female population? Any additional profiles /percentages given? Recent studies designed with ethnically-diverse subjects consistently demonstrated quantitative metabolic differences, rates of absorption, inherent biological variances, etc.
Personally, I'll go for the chocolate-covered Dunkin Donut over a daiquiri any day but it would be interesting to know more about the design of this study.”

“Re: the design of the study, what was the exclusionary criteria? A direct correlation between age and I/Q or are we seeing medical conditions, medications, lifestyle habits (i.e., smoking, drinking) factored in? I can't imagine those variables weren't screened out but I'm curious. No mention of this in your article. Great writing as always!”

“thanks for commenting.
the study had two separate cohorts and in one environmental factors such as education, smoking, drinking, eco status etc.were factored in. There was still an IQ difference, but not as great.”
