Skin lesions like moles and cherry angiomas arise from genetic factors and can’t be prevented. However, you may be able to reduce your risk for other skin lesions by developing good habits. Have a good skincare routine, and avoid skincare products that might clog your pores. Avoid allergens and be careful not to cause damage or injury to your skin. To reduce your risk of skin cancer, wear sunscreen, limit time spent in the sun, and avoid using tanning beds.
