Freckles are small brown spots usually found on the face and arms. Freckles are extremely common and are not a health threat. They are more often seen in the summer, especially among lighter-skinned people and people with light or red hair.
Since freckles are almost always harmless, there really is no need to treat them. As with many skin conditions, it's best to avoid the sun as much as possible, or use a broad spectrum sunscreen with at least 7% zinc oxide physical blocker and SPF 30. This is especially important because people who freckle easily (for example, lighter-skinned people) are more likely to develop skin cancer. Read more about moles, freckles and skin tags.
