Detailed answer

While salicylic acid and tea tree oil are commonly used to treat acne and reduce whiteheads, it is possible for whiteheads to still occur. This can happen due to a few reasons. Firstly, the effectiveness of any topical treatment can vary from person to person, so it may not fully prevent whiteheads for everyone. Secondly, if the salicylic acid and tea tree oil products are not formulated properly or used incorrectly, they may not effectively target the underlying causes of whiteheads. Additionally, other factors such as hormonal changes, diet, and skincare routine can also contribute to the development of whiteheads. Therefore, even with the use of salicylic acid and tea tree oil, it is important to maintain a consistent and comprehensive skincare routine to minimize the occurrence of whiteheads.
