Applying sunscreen can sometimes cause stinging or burning, but dermatologists stress that this discomfort should not deter people from using sun protection. Dr Aditi Senthilnathan, a board-certified dermatologist at the University of Pennsylvania's Perelman School of Medicine, notes that complaints of sunscreen stinging are common, particularly around the eyes after sweating.
Why Does Sunscreen Sting?
Dr Sungat Grewal, double board-certified dermatologist and co-director of the UCSF Dermatology Laser & Cosmetic Center, explains that not all sunscreens are formulated the same. Two products with the same SPF can feel very different on the skin. Stinging may be caused by alcohol-based formulas, certain UV filters, or preservatives that irritate sensitive skin, according to Dr Elizabeth Bahar Houshmand, double board-certified dermatologist and founder of Houshmand Dermatology & Wellness in Dallas, Texas.
Dr Joyce Teng, professor of dermatology at Stanford University, adds that non-active ingredients added for consistency or scent can also cause skin irritation. People with rosacea, eczema, or those using acne treatments, retinoids, exfoliating acids, or benzoyl peroxide are more likely to experience sensitivity. Over-cleansing or using too many active ingredients can disrupt the skin barrier, making it less tolerant of certain products.
What to Do If Your Sunscreen Stings
There are two main types of sunscreen: chemical and physical (mineral). Chemical sunscreens contain ingredients like oxybenzone and avobenzone that absorb UV rays, while physical sunscreens use zinc oxide and titanium oxide to reflect UV light. Dr Senthilnathan recommends switching to a fragrance-free, alcohol-free physical sunscreen, as zinc oxide and titanium oxide are less likely to cause stinging. She also suggests using a water-resistant sunscreen to prevent dripping into the eyes, and rinsing eyes with water if sunscreen gets in them.
Dr Grewal advises applying a gentle moisturizer beforehand to strengthen the skin barrier and improve comfort. However, if the reaction is severe—such as rash, swelling, itching, or persistent burning—Dr Houshmand says to see a board-certified dermatologist, as this may indicate irritation or contact dermatitis.
How to Ensure Sunscreen Works Effectively
The best sunscreen is one you will use daily, ideally multiple times a day. Experts recommend a broad-spectrum sunscreen with an SPF of at least 30, which blocks about 97% of UV rays. For the face and neck, Dr Houshmand suggests using two finger lengths of sunscreen; for the body, a shot glass amount. Apply sunscreen 15 minutes before sun exposure and reapply every two hours, or sooner after swimming, sweating, or towel drying.
Dr Houshmand emphasizes that sunscreen is only one part of sun protection, also recommending seeking shade, wearing a wide-brimmed hat, sunglasses, and UPF clothing.
