For those experiencing discomfort, switching to fragrance-free, alcohol-free physical sunscreens can help. Dr. Senthilnathan states that zinc oxide and titanium oxide are less likely to cause stinging.
She also recommends water-resistant options to prevent the formula from dripping into the eyes during physical activity. If sunscreen gets into the eyes, rinse immediately with clean water.
Applying a gentle moisturizer before sunscreen can create a protective barrier and improve comfort.
When to See a Dermatologist
If sunscreen causes a rash, swelling, itching, or persistent burning, it may indicate irritation or contact dermatitis, and a board-certified dermatologist should be consulted, says Dr. Houshmand.
Dermatologists emphasize that the best sunscreen is one you will use consistently. It should offer broad-spectrum protection against UVA and UVB rays with at least SPF 30.
For the face and neck, most adults need two finger lengths of sunscreen. For full body coverage, apply an amount equivalent to a standard shot glass.
Apply 15 minutes before sun exposure and reapply every two hours or after swimming.

Dr. Senthilnathan adds that sunscreen is only one part of sun protection; seeking shade, wearing a wide-brimmed hat, sunglasses, and UPF clothing are also recommended.
