Sun cream can be applied to sunburn in dog days, which can effectively resist the damage of ultraviolet rays and reduce the risk of sunburn and skin cancer. However, the following points should be noted:
1. Choose a sunscreen suitable for your skin type and needs. It is generally recommended to choose a product with an SPF value of more than 30.
2. Use sunscreen correctly and evenly to avoid missing any part. It is recommended to apply it 20 minutes before going out, and reapply it every 2-3 hours.
3. Wearing sunscreen can not completely avoid sunburn. It is also necessary to avoid exposure to strong sunlight and try to rest in the shade.
4. If the skin has been sunburned, do not wear sunscreen, and use soothing and repairing products.
