Modern Dermabrasion Techniques: A Personal Appraisal

The conversation discusses using high molecular weight hyaluronic acid after microneedling to form a protective barrier, though it's considered expensive and offers marginal improvement. Users share experiences with different microneedling tools like derma rollers, dermastamps, and Dr. Pen, with some opting not to use any products on the scalp.

OP injured their temple using derma rolling and tretinoin, causing peeling and potential hair follicle damage. Users suggest the injury might be permanent, possibly resulting in scar tissue where hair won't grow.

Carnosic acid in rosemary extract may enhance skin repair and promote hair follicle regeneration. It could be used alone or with verteporfin for scarless healing after dermal wounding.

Minoxidil may cause dark circles and affect collagen, and Tretinoin might help counteract these effects. Users suggest caution with Tretinoin due to potential Vitamin A toxicity and recommend using it sparingly with sunscreen and moisturizer.

Use tretinoin three times a week, dermaroll once a week, and apply minoxidil daily, but avoid using all three on the same day. Tretinoin is preferred over hydrocortisone and should not be used immediately after dermarolling.

Minoxidil may inhibit collagen synthesis at high concentrations, with anecdotal reports of skin aging but limited research. Dermatologists and other specialists show little interest in studying minoxidil's side effects.
