It's generally not recommended to use petroleum-based products like Vaseline on a fresh tattoo. While Vaseline may provide a barrier to prevent moisture loss and help with itching, it can also clog pores and trap bacteria in the skin, potentially leading to infections or other complications.

Instead, most tattoo artists recommend using a specialized tattoo aftercare product, such as a fragrance-free, non-alcoholic moisturizer or ointment. These products are designed specifically for tattoo healing, and are typically formulated with ingredients like shea butter, coconut oil, or aloe vera that help soothe and nourish the skin without causing irritation or other issues.

It's important to follow your tattoo artist's aftercare instructions carefully and to avoid using any products that they have not specifically recommended. If you have concerns about your tattoo healing properly or notice any signs of infection, be sure to contact your tattoo artist or a healthcare provider right away.
