What would be medical advantages?
There are several problems with what you're asking. It has to do with how you're framing the issue. But rather than get into a more convoluted point, I'll just answer your question:
- Reduced psychosocial well-being
- Longer term scarring
Maybe that matters to you, maybe it doesn't. For some people it can impact their life in a significant way, leading to depression, etc. Then again, the retinoid treatments for acne can also lead to depression or worse.
"Remaining a virgin at age 40" may not have an ICD-10 code, but it doesn't mean it's not a risk factor of acne worthy of attenuating.
Such as avoiding risk for infections, or other?
No, quite the opposite is possible:
Antibiotic Treatment of Acne May Be Associated With Upper Respiratory
Objective To determine if the long-term use of antibiotics for the treatment of acne results in an increase in either of 2 common
infectious illnesses: upper respiratory tract infections (URTIs) or
urinary tract infections.
Design Retrospective cohort study.
Setting General Practice Research Database of the United Kingdom, London, England, from 1987 to 2002.
Patients Patients with a diagnosis of acne.
Main Outcome Measure The onset of either a URTI or a urinary tract infection.
Results Of 118 496 individuals with acne (age range, 15-35 years) who were identified in the General Practice Research Database, 84 977
(71.7%) received a topical or oral antibiotic (tetracyclines,
erythromycin, or clindamycin) for treatment of their acne and 33 519
(28.3%) did not. Within the first year of observation, 18 281 (15.4%)
of the patients with acne had at least 1 URTI, and within that year,
the odds of a URTI developing among those receiving antibiotic
treatment were 2.15 (95% confidence interval, 2.05-2.23; P<.001) times
greater than among those who were not receiving antibiotic treatment.
Multiple additional analyses, which were conducted to show that this
effect was not an artifact of increased health care–seeking behavior
among our cohorts, included comparing the cohorts of patients with
acne with a cohort of patients with hypertension and the likelihood of
developing a urinary tract infection.
Conclusions Patients with acne who were receiving antibiotic treatment for acne were more likely to develop a URTI than those with
acne who were not receiving such treatment. The true clinical
importance of our findings will require further investigation.
