Stem cell treatment for acne scars involves a multi-step process often conducted in a clinical or dermatological setting. Initially, the procedure begins with a consultation to assess the severity of the acne scars and determine the suitability of stem cell therapy for the patient. If deemed appropriate, the treatment typically starts with the extraction of adipose tissue, commonly from areas like the abdomen or thighs, through a minor liposuction procedure. This tissue is then processed to isolate mesenchymal stem cells, which possess regenerative properties. The adipose-derived stem cells are purified and concentrated, creating a solution ready for injection into the affected areas.

Once the stem cells are prepared, the target sites are cleaned and numbed using a local anesthetic to ensure patient comfort. A series of precise micro-injections are then administered into and around the scar tissue. These stem cells work by promoting the regeneration of new, healthy skin cells and facilitating collagen production, which helps in improving the skin's texture and reducing the appearance of the scars. Post-treatment, patients may experience mild swelling or redness, which generally subsides within a few days. Follow-up sessions might be recommended depending on the scar's severity and the individual's response to the treatment. For optimal results, these procedures are often combined with other skin rejuvenation techniques like microneedling or laser therapy.
