No, hot water doesn't directly wash off a tan, but it significantly accelerates its fading. Hot water strips the skin of its natural oils, leading to quicker tan loss. Therefore, while it doesn't remove the tan instantly like soap might remove makeup, it contributes to its premature fading.
Why Hot Water Affects Your Tan
-
Oil Stripping: Hot water removes essential oils from your skin. These oils help to retain moisture and lock in the tan's color. By depleting these oils, your skin becomes drier and the tan pigments are more easily shed. (Source: "Hot water can be detrimental to your tan's lifespan. It can strip your skin of essential oils, causing your tan to fade more quickly.")
-
Accelerated Cell Turnover: Hot water can also increase skin cell turnover. Since your tan resides in the outermost layer of skin, a faster cell turnover rate means your tan is shed more quickly.
-
Overall Damage: Prolonged exposure to hot water, such as long baths or showers, further exacerbates the drying and cell turnover processes, resulting in faster tan fading. (Source: "Additionally, avoid long soaks in hot baths or hot tubs, as they can also accelerate tan fading.")
Best Practices for Showering with a Tan
Instead of hot water, opt for lukewarm or cool showers to preserve your tan. Keep showers short and avoid harsh scrubbing. Moisturizing after showering helps to counteract the drying effects of water and maintain your tan's longevity. (Source: "Avoid exposure to hot water, as it can cause your tan to fade and come off at a faster rate. Keep your skin healthy with a daily moisturizer,")
Multiple sources recommend waiting several hours, often 6-24, after getting a spray tan before showering, using lukewarm water, and avoiding soap or harsh scrubbing. (Source: "It is recommended to wait 6-24 hours before your first shower. 2. Rinse with warm water alone. Do not use soap or body wash before the 24 hour…")
