While we have a good understanding of why acne occurs, the reason acne goes away as people age is still unclear. In general, acne tends to improve or disappear in many individuals after the age of 20. However, some people experience acne well into their thirties, forties, or even beyond. Yet, it is still not entirely understood why acne often fades with age for some people, while others continue to struggle with it much later in life.
Why Some People Never Experience Acne Again After Isotretinoin
One of the most fascinating aspects of isotretinoin treatment is its ability to potentially offer a permanent solution. Acne that has been effectively treated with isotretinoin often doesn’t return, even years after completing the treatment. This is in contrast to other acne treatments, which may only offer temporary relief, requiring long-term management.
However, the reason for this lasting effect remains unclear. It’s possible that isotretinoin alters the skin’s sebum production and the functioning of sebaceous glands in such a way that acne doesn’t return. But since we don’t fully understand the long-term mechanisms at play, we can’t explain why acne tends to “disappear” for some individuals after isotretinoin treatment.
There’s also the possibility that some individuals were naturally approaching the end of their acne journey when they started treatment, meaning their acne would have resolved with or without the medication. For example, individuals who begin isotretinoin treatment at the age of 19 may have been on the cusp of entering the age where acne typically clears up anyway.
Why Does Acne Go Away for Some and Not Others?
There is still no clear answer as to why acne naturally fades with age for some people and persists for others. One hypothesis is that hormonal fluctuations, particularly in women, can contribute to persistent acne. Hormonal changes during menstruation, pregnancy, or menopause may trigger acne outbreaks even in individuals who never had acne during their teenage years.
While isotretinoin offers a strong solution for those with persistent acne, it’s important to note that it doesn’t work for everyone. Some people may not achieve lasting results, and for others, acne may recur over time. Regardless, isotretinoin remains one of the most effective treatments for severe acne available today.
