How Much Sunscreen is Enough?
The amount of sunscreen needed depends on the area being covered. For your face and neck, apply a nickel-sized dollop, approximately half a teaspoon or two finger lengths. For your entire body, use one ounce, enough to fill a shot glass.
- Face and Neck: A nickel-sized amount (approximately 1/4 teaspoon or 1.25ml) is sufficient to cover the face and front of the neck. This is equivalent to about two finger lengths. [Source: Dr. Marisa Garshick, MD; Multiple online sources]

- SPF: Choose a sunscreen with an SPF of 30 or higher for optimal protection. [Source: Multiple online sources]
- Coverage: Ensure all exposed skin is covered. Don't forget often-missed areas like the ears, tops of feet, and back of the neck. [Source: American Academy of Dermatology]
Remember that using the correct amount is crucial for achieving the advertised SPF protection. Insufficient application significantly reduces effectiveness.
