How does acne treatment defer for someone in his 40s or 50s?

Thank you for the question. This is a very interesting observation and there are a few clinical studies published that have indeed shown an association between dairy intake and acne. High dairy intake been shown to be associated with acne. A high glycaemic index diet e. g. diet rich in refined sugars, has also been linked to acne. Taking excessive cakes and ice cream may not the best for your acne. The cause of acne is multifactorial and diet control alone may not be sufficient to control acne.

As inflammation from an acne breakout resolves, it may leave behind residual redness (post-inflammatory erythema, PIE), brown pigmentation (post-inflammatory pigmentation, PIH), or true scars (pitted or raised). Often times, a patient may have any combination of PIE, PIH and true scars. Developing new scars often have redness within them as well. Although PIE and PIH tend to resolve over time (as opposed to permanent true scars), these blemishes are understandably frustrating and treatment is commonly requested.
