Depending on the formulation technology, you may achieve the same SPF while using less amount of Active Ingredients (so that the cost is less too), this must be the case, as long as they have clinical test data to back up their SPF claim, but, who knows? Sometimes, the testing lab not so good they may not follow test procotol correctly and produce false data. Does the percentage of the active ingredients matter, or is it only important to look at the SPF number? For example, if one sunscreen has Zinc Oxide (10.0%), Titanium Dioxide (7.5%) as the active ingredients, and another one has Titanium Dioxide 4%, Zinc Oxide 4%, but they both say SPF 50, are they both equally effective, or is the higher percentage better? My Dad the Chemist’s take on active ingredient percentages My message to My Dad the Chemist Let’s see what my Dad the Chemist thinks. Now I have to add yet another layer to my search?…Active ingredient percentage? The other sunscreens I’ve used in the past, including Olay Sensitive Skin Moisturizer SPF 15 and NO-AD Sport Sunscreen SPF 50 were both listed as recommended products.Īnyway, back to the percentage of active ingredients…is this yet another thing we have to watch out for when we look at the label? The path for me goes: look for the words SPF 30+ -> look for “broad spectrum” -> look for physical sunscreen ingredients ->look for the words non-comedogenic. I was sad to see that my latest favorite, Australian Gold, wasn’t listed there, but that might not mean anything (I hope). You can visit the site to see if your favorite sunscreen earned the Seal of Recommendation. However, it can’t hurt for a product to have this Seal of Recommendation, right? It doesn’t provide much data about how the committee validates the claims in the scientific data that manufacturers provide. According to the website, in order to gain a Seal of Recommendation, the manufacturer must give proof (scientific data) that its product can successfully block ultraviolet radiation. The Skin Cancer Foundation has something called a Seal of Recommendation that it gives to select sunscreens. Is there anything we should be looking for? The study concluded that in order to help ensure that you’re getting a sunscreen that delivered true SPF 30 protection, it may be safer to buy a sunscreen with an SPF that’s higher than 30. It also found that 80 percent of the chemical sunscreens they tested with an SPF claim of 40–100 were found to deliver at least SPF 30, while only 20 percent of mineral sunscreens held true to that claim. In 2016, Consumer Reports conducted a study that found that almost half of sunscreens (and almost 75% of natural sunscreens) did not pass tests that verified the SPF claims on their labels. SPF claims! What are they good for? Absolutely nothing? So the FDA has published this Industry Guidance for nonprescription sunscreen drug products. I did some research on the topic, and by “research”, I mean that I frantically Googled things like, “spf claims lab test”, “how to check spf claims”, “spf sunscreen test results”, “independent lab sunscreen spf effectiveness”…but I only came back with a few findings.
