It is not recommended to apply sunscreen and tanning oil together. Tanning oil is designed to enhance the tanning process by attracting more UV rays to the skin, which can increase the risk of sunburn and skin damage. Sunscreen, on the other hand, is meant to protect the skin from harmful UV rays. It is best to apply sunscreen first, allow it to absorb into the skin, and then apply tanning oil if desired, but always prioritize sun protection. **

It is recommended to apply sunscreen first before tanning oil. Sunscreen helps to protect the skin from harmful UV rays, while tanning oil is designed to enhance the tanning process. Applying sunscreen first ensures that your skin is protected from sunburn and long-term damage, while still allowing you to achieve a tan with the help of tanning oil. This approach prioritizes skin protection while still allowing for a bronzed glow. **

I recommend using a broad-spectrum sunscreen with at least SPF 30 to protect your skin from both UVA and UVB rays. Look for a sunscreen that is water-resistant and suitable for your skin type. As for tanning oil, it's important to note that tanning oils do not provide sun protection and can actually increase the risk of sunburn and skin damage. Instead, consider using a self-tanning lotion or spray to achieve a bronzed look without the harmful effects of UV exposure. **
