No, Vaseline does not help with tanning in the way that tanning oils or lotions do. In fact, using Vaseline while tanning can be harmful.
The Dangers of Using Vaseline While Tanning
Applying Vaseline before sun exposure can actually increase your risk of sunburn. This is because Vaseline acts as an occlusive, meaning it creates a barrier on the skin. While it might seem like this would protect your skin, it actually traps heat and intensifies the sun's rays, leading to more severe burns. As one source states, "Tanning with petroleum jelly can cause damage to the skin, as it helps to attract and intensify the sun's rays on the skin," resulting in increased sunburn and skin irritation.

Some sources suggest Vaseline can be used strategically with self-tanning products to prevent over-staining of dry areas. Applying a thin layer to dry patches like elbows and knees acts as a barrier, preventing excessive color absorption.

Vaseline and Existing Tans
Vaseline does not fade a tan. It acts as a barrier, preventing moisture loss, which might indirectly help maintain the tan for a slightly longer period. However, this is not because Vaseline actively contributes to the tanning process but because it helps retain the skin's hydration. [Source: r/SkincareAddiction]
Conclusion
While Vaseline has some uses in relation to tanning (protecting dry areas from over-staining with self-tanner), it should never be used to enhance tanning from sun exposure. Using it in this way can lead to severe sunburns and skin damage.
