Medical experts recommend using sunscreen with at least SPF 30 to protect the skin from harmful ultraviolet rays during summer activities [1].
Proper application and product selection are critical for preventing sunburn and long-term skin damage. As outdoor activities increase during the summer months, following clinical guidelines helps ensure that the skin remains protected from UV exposure [3].
Jennifer Lucas, MD, a dermatologist at Cleveland Clinic, said the sun protection factor is important. "The most important thing when you're grabbing your bottle of sunscreen is that it's at least 30 SPF," Lucas said [1].
Beyond the SPF rating, the order of application affects the efficacy of skin care routines. The American Academy of Dermatology (AAD) said to apply moisturizer first, followed by sunscreen, for optimal hydration and protection from UV rays [2]. This sequence ensures the sunscreen forms an effective barrier on the surface of the skin.
Experts from the Mayo Clinic and other medical institutions said that users can choose between chemical or mineral formulations based on personal preference [1]. The primary goal is consistency, choosing a product that the user will actually apply daily.
Guidelines for preventing sunburn were highlighted in reports as early as June 26, 2025, urging the public to maintain these habits during peak summer months in the U.S. [3]. Dermatologists said that the best sunscreen is the one that a person is willing to use consistently to maintain a shield against the sun's rays.
“"The most important thing when you're grabbing your bottle of sunscreen is that it's at least 30 SPF."”
This guidance emphasizes a shift toward standardized minimums for UV protection rather than chasing extremely high SPF numbers, which can provide a false sense of security. By prioritizing the sequence of application—moisturizer then sunscreen—medical professionals are addressing common consumer errors that may reduce the product's effectiveness.
