From my experience, applying self-tanner without considering the weather can lead to unexpected results. For instance, if it's humid or you're expecting rain, the self-tanner might not set properly, causing uneven color or streaks. On the other hand, if you know you'll be in the sun, some self-tanners may react differently, so choosing one that suits the conditions can make a big difference. I always check the forecast to plan my self-tanning sessions. If the weather predicts rain or heavy sweating, I postpone the application to ensure the tan develops well and lasts longer. Also, exfoliating your skin beforehand and moisturizing dry areas helps the tanner apply more evenly. Keep in mind that temperature and humidity are key factors affecting drying time and pigment development. Another tip is to allow enough time after applying self-tanner before showering or exercising, especially on days when the weather is warm. This helps prevent the tan from washing off prematurely or creating blotchy spots. By incorporating these small habits and staying aware of the forecast, I’ve had much better success with self-tanning, achieving a natural-looking glow that lasts.
