To achieve the best results when using Ubatuba Tan's tanning oil, it is recommended to apply the oil evenly to your skin before sun exposure. The tanning oil should be applied in a thin layer and massaged into the skin to ensure even coverage. It is important to remember to reapply the tanning oil every 1 to 2 hours to avoid over-tanning too quickly. Additionally, it is recommended to use sunscreen in addition to the tanning oil to protect your skin from sun damage. Ubatuba Tan's tanning oils are made with natural and organic ingredients and do not contain any chemicals.
