What would happen if I put on Vaseline petroleum jelly before tanning?

Curiosity about skincare and tanning is always valid, no matter the question! Applying Vaseline petroleum jelly before tanning might seem like an unconventional approach, but it raises interesting considerations. While Vaseline creates a thick barrier that locks in moisture, it can also prevent tanning products from adhering properly to your skin. This could result in an uneven tan or a shiny appearance that may not be desirable.
