Sunscreen is a crucial part of sun protection, but for some people, applying it can cause stinging or burning. This discomfort is not uncommon, and experts emphasize that it should not deter anyone from using SPF.
Why Does Sunscreen Sting?
Dr. Aditi Senthilnathan, a board-certified dermatologist at the University of Pennsylvania’s Perelman School of Medicine, notes that complaints of sunscreen stinging are frequent. She adds that burning or stinging around the eyes after sweating is also a common issue.
Dr. Sungat Grewal, a 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, and some formulas may cause irritation due to their ingredients.
Alcohol-based sunscreens or those containing certain UV filters and preservatives can be irritating, especially for individuals with sensitive skin, according to Dr. Elizabeth Bahar Houshmand, a double board-certified dermatologist in Dallas, Texas. Dr. Joyce Teng, professor of dermatology at Stanford University, adds that non-active ingredients added for consistency or scent can also lead to skin irritation.
Who Is More Likely to Experience Stinging?
Certain groups are more prone to sunscreen sensitivity, says Dr. Houshmand. These include people with rosacea or eczema, those undergoing acne treatments, and individuals using active skincare ingredients like retinoids, exfoliating acids, or benzoyl peroxide. Over-cleansing or using too many active products can disrupt the skin barrier, making it more sensitive and less tolerant of certain sunscreens.
How to Prevent Sunscreen Stinging
There are two main types of sunscreen: chemical and physical (mineral). Chemical sunscreens contain compounds like oxybenzone and avobenzone that absorb UV rays, while physical sunscreens use minerals like zinc oxide and titanium oxide to reflect UV light. Dr. Senthilnathan recommends switching to a fragrance-free, alcohol-free physical sunscreen for those who experience stinging, as zinc oxide and titanium oxide are less likely to cause irritation.
She also suggests using a water-resistant sunscreen to prevent the product from dripping into the eyes during sweating. If sunscreen does get into the eyes, rinsing with water is advised. Applying a gentle moisturizer beforehand can help create a barrier and improve comfort, says Dr. Grewal.
However, if a severe reaction occurs—such as rash, swelling, itching, or persistent burning—it may indicate irritation or contact dermatitis, and a board-certified dermatologist should be consulted, warns Dr. Houshmand.
Choosing an Effective Sunscreen
Experts agree that the best sunscreen is one you will use daily, ideally multiple times a day. It should be broad-spectrum, protecting against both UVA and UVB rays, and have an SPF of at least 30, which blocks about 97% of UV rays.
For application, Dr. Houshmand recommends two finger-lengths of sunscreen for the face and neck, and a shot glass amount for the body. Sunscreen should be applied 15 minutes before sun exposure and reapplied every two hours, or sooner after swimming, sweating, or towel drying.
Dr. Houshmand emphasizes that sunscreen is only one part of sun protection. Seeking shade, wearing a wide-brimmed hat, sunglasses, and UPF clothing are also important measures.
