Dr Eglė Aukštuolienė explains that "teen acne can take a long time to treat. The first improvements usually start to occur after 4-6 weeks, as long as your skin tolerates the treatment. However, several months (sometimes four or more) can be necessary to achieve optimal results."
In most cases, teen acne treatments don’t provide the expected results as patients think the improvement will be very fast. They stop the treatment prematurely, after only a couple of weeks, if they don’t immediately get the results they want. What’s more, much of the medication used to treat acne irritates the skin, so at the beginning of the treatment your face may become red, dry, scaly and itchy. These undesirable side effects can be an obstacle, despite being relatively easy to eliminate.
