If I go tanning right before bed, should I still wash my face before I go to sleep? Or is it okay to wash my face before I go tanning, then go tanning, then go to bed?

When out in the sun, or in a tanning bed I never use soap on my face before bed. I splash some water on it and pat dry and put on my moisturizer same as always.

I guess it all depends on how much make up you have on. I don't wear make up.

You can wash your face with soap or a cleanser before you go tanning. After tanning, don't use soap on your face the same day because soap will make your skin dry and may peel your tan. However, you can rinse your face with luke warm water and then apply a moisturizer before you go to bed to prevent your skin from becoming dry.

If I went tanning today around 5, would it be bad to go tanning tomorrow around 3? I know you are supposed to wait 24 hours, but does 2 hours really make a difference?

It takes several sessions to get a good tan. So you have to tan regularly if you want to maintain your tan and keep it from fading. It's recommended that you wait at least 24 hours between each session. If you don't want to wait the full 24 hours, then you can go tanning in 22 hours. Just be careful when you go tanning and always protect yourself from the UV rays.
