If your self-tanner has settled into your pores, it usually means they were still open during application. Warm water and steam from a shower can open your pores, so if you apply self-tanner right afterward, it may settle unevenly. To avoid this, wait at least 2–3 hours after showering to allow your pores to naturally close. You can also help them contract by using something cold on your skin, such as rinsing your face with cold water or gently gliding an ice cube over your skin before applying the self-tanner.
