When basking in the sun, applying sunscreen is a must. But what happens when your protective layer starts to sting? This discomfort is more common than you might think, and experts urge that it shouldn’t deter you from using SPF. Understanding why some formulations irritate the skin can help you make better choices for sun protection.
The Science Behind Sunscreen Sensitivity
Dr. Aditi Senthilnathan, a board-certified dermatologist at the University of Pennsylvania’s Perelman School of Medicine, notes that complaints about sunscreen stinging are frequently reported. “We often hear about burning or stinging, especially around the eyes after sweating,” she explains. While this issue can be bothersome, experts caution against abandoning sunscreen altogether.
Dr. Sungat Grewal, a double board-certified dermatologist and co-director of the UCSF Dermatology Laser & Cosmetic Center, emphasises that all sunscreens are not created equal. “Two products with identical SPF ratings can feel vastly different on your skin,” he says.
What Causes the Sting?
The irritation some individuals experience can often be traced back to the ingredients within the sunscreen. Certain formulations that contain alcohol, specific UV filters, or preservatives can be problematic, particularly for those with sensitive skin. Dr. Elizabeth Bahar Houshmand, founder of Houshmand Dermatology & Wellness in Dallas, Texas, notes that these components can lead to discomfort for some users.
Moreover, Dr. Joyce Teng, a professor of dermatology at Stanford University, points out that additives designed to enhance texture or fragrance may also provoke irritation. Those with conditions like rosacea or eczema, or individuals using aggressive acne treatments or active skincare ingredients, are particularly vulnerable. Excessive cleansing or layering too many active components can compromise the skin barrier, heightening sensitivity and discomfort.
Navigating Sunscreen Choices
There are two primary categories of sunscreen: chemical and physical (or mineral). Chemical sunscreens, which include ingredients like oxybenzone and avobenzone, work by absorbing harmful rays. In contrast, physical sunscreens utilise minerals like zinc oxide and titanium dioxide, reflecting UV rays away from the skin.
If you find yourself experiencing stinging or burning sensations, Dr. Senthilnathan suggests switching to a fragrance-free, alcohol-free physical sunscreen. “Zinc oxide and titanium oxide are less likely to cause irritation,” she advises. Additionally, opting for a water-resistant formula can prevent the product from dripping into the eyes when you sweat. Should sunscreen inadvertently enter your eyes, rinsing them with water is recommended.
Applying a gentle moisturiser before your sunscreen may also act as a barrier, enhancing comfort. However, if the irritation escalates to a rash, swelling, or persistent burning, seeking professional advice from a board-certified dermatologist is essential.
Ensuring Effective Sun Protection
Regardless of whether you choose a chemical or physical formulation, the most effective sunscreen is the one you’ll apply daily. It’s crucial to select a broad-spectrum product with an SPF of at least 30, which blocks approximately 97% of UV rays.
Dr. Houshmand recommends that for the face and neck, most adults should apply two finger lengths of sunscreen, while a shot glass amount is ideal for the body. For maximum effectiveness, sunscreen should be applied 15 minutes before sun exposure and reapplied every two hours, or more frequently after swimming, sweating, or towel drying.
“Sunscreen is just one facet of sun safety,” she adds. Incorporating shade, wearing a wide-brimmed hat, sunglasses, and UPF clothing can further enhance your protection against harmful UV radiation.
Why it Matters
Understanding the nuances of sunscreen formulations and the reasons behind skin irritation is vital for anyone looking to safeguard their skin from the sun’s harmful rays. With the right knowledge and choices, you can enjoy the outdoors confidently, knowing you are adequately protected without the discomfort. Making informed decisions about sunscreen can lead to a healthier, more enjoyable sunbathing experience, allowing you to soak up the sun without fear of irritation.
