If you have dark brown or black skin, you may not notice a change in your skin color after tanning. However, you can still develop a sunburn after 40 to 60 minutes.

Keep in mind that you can get sun exposure on a cloudy day, too. Just because you can’t see the sun doesn’t mean it’s not shining.

If you tan often and for long periods of time, you could experience leathery skin, wrinkled skin, or dark spots. Tanning too much also increases your risk of skin cancer.

There are 2 types of sunscreen: physical blocking and chemical. Physical blocking sunscreens have zinc and titanium, and start protecting your skin right away. Chemical sunscreen takes 20 minutes to soak into your skin, and doesn’t provide instant protection.
