Do not apply sunscreen with insect repellent
Hot and humid. Insects are out. The natural reaction is to apply sunscreen and add some insect repellent — a two-in-one solution, so to speak. The latter is essentially a chemical cocktail. In the height of summer, sunscreen and insect repellent might seem like the perfect duo, writes https://xrust.ru/. However, a recent study has shown that this duo can render sunscreen ineffective. Scientists treated human skin samples with both products and exposed them to sunlight and UVB rays. What they discovered was astonishing. The sunscreen worked well, but when repellent was added, the protection dropped dramatically. The reason was the thinning of the sunscreen layer.
As for the numbers, a 1997 study showed that DEET, a common ingredient in insect repellents, reduced SPF by 34%. However, in some cases during the 2025 study, it was as if no sunscreen had been applied at all. Based on the research, the U.S. Department of Health recommended against using “two-in-one” products. Sunscreen needs to be applied more often than repellent, and overusing repellent can be harmful due to its toxicity. Therefore, it’s better to avoid combining them altogether.
