That's a bad idea.

No. You don’t get a meaningful tan from mixing them—you just increase your risk of burning.

Sunscreen blocks UV rays. Tanning oil encourages absorption by removing the sunscreen’s protection. The result isn’t a magical middle ground; it’s a patchy, unreliable layer of protection that makes you think you’re safe when you’re not. You’ll either burn or spend longer in the sun than you should, chasing a tan that your sunscreen is actively preventing.

If you want to tan safely, don’t use tanning oil at all. Use a good sunscreen and let your color come from gradual, controlled exposure. Tanning oil is for people who want to skip the “safe” part. Your skin will thank you later.
