Before treating your acne scars
, it is important to treat acne first in your case.
At the age of 35, if new pimples are appearing means either you have dandruff or hormonal imbalance leading to acne.
In case of dandruff, use Ketoconazole
shampoo, maintain scalp hygiene.
Hormonal imbalance, if present need to be dealt completely. PCOD is common underlying problem.
Once your new pimples are coming under control then you can treat scars either with laser treatment/filler substances/chemical peeling/cryotherapy
with or without steroid injections.
So consult dermatologist
, find out cause for acne and treat it.
