How Much Sunscreen Should You Apply?

Educational information only; not medical advice. Follow the exact product label and consult a qualified professional for personal questions.

Short answer

Use enough to cover all exposed skin, and follow the product label. The American Academy of Dermatology describes about one ounce for an average adult’s exposed body and approximately one teaspoon for the face in its application guidance. Amount varies with body size and exposed area.

A practical routine

  1. Apply before going outdoors as directed on the label.
  2. Cover commonly missed areas such as ears, neck, hands, and the tops of feet.
  3. Reapply at least every two hours when outdoors, and sooner after swimming, sweating, or toweling when the label directs.
  4. Keep using shade, clothing, a hat, and sunglasses; sunscreen is one layer of sun protection.

FAQ

Can I use a stick as my only application?

A stick can be convenient, but coverage depends on applying enough and evenly. Follow its label and do not assume a few quick swipes equal a full application.

What about makeup?

Treat reapplication as a coverage problem first. A touch-up format may be convenient, but it does not remove the need to apply an adequate amount.

Compare stick and lotion formats and review layered protection.
