Is it okay to use nose strips if my nose is very red and oily and I have blackheads?

Yes, but before you use it, you need to wash your face, and then use it according to the instructions. Generally, you wet your nose, then stick it on your nose, wait for about 10 minutes, and wait for the nose stick to wear. After drying, tear it off slowly. Do not tear it off too fast, otherwise it will cause the pores to become larger. Also, do not use this method too much, otherwise it will dry out the skin and enlarge the pores. Use it in about a week. Once or so is better.
