Should I do fully-ablative CO2 laser, or is there a better option for me? (Photo)

Results from ablative CO2 laser resurfacing can vary, but you have a good skin type for the procedure.  I have not seen this procedure create enlarged pores or fat loss.  In fact, the procedure should help improve large pores.  The laser should not penetrate deep into the fat layer, so this should not be affected.

Based on your photos, it appears you might be a very good candidate for an ablative CO2 treatment. This procedure would work deeply enough into the dermal tissue to produce dramatic improvement in your skin. I would caution you that this is an intense treatment that requires experience and expertise to perform correctly. I recommend scheduling a consultation with a very experienced, board-certified dermatologist for further assessment and a customized treatment plan.

co2 will help alot but you will need more long term treatments with halo, peels, and dermarolling.

Acne scar treatment needs a combination approach for improvement.  For the best results, one should target the acne scar type.  As everyone has a unique pattern of acne scarring, the best solution is a tailored one.  Typically you need fillers like bellafill and sculptra for atrophic indented type scars with or without subcision.  Subcision for depressed tethered scars.  Vascular lasers like yellow laser, aerolase, excel V or IPL for redness or thick scars. And lasers such as fraxel, erbium, co2 or fractional radiofrequency like venus viva, skinfinity, intensif or fractora microneedling RF for textural issues and superficial scarring.  Deep ice pick scars and narrow box car scars are best treated with TCA CROSS and punch excision.  All lasers are combined with microneedling and PRP to get even better results and improve healing times.   The majority of patients will have a collection of different scar types, and hence a tailored treatment plan is needed by an expert physician.  It is never about the laser or product that gives the results, its about the expert behind the equipment that gets you the outcome.  Scars cannot be cured and will need life-long treatments to maintain and build on the results.  For those at high risk for hyperpigmentation (darker skin types or asian or hispanic or mixed ethnicities) we already pre-treat the skin with cosmelan or enlighten lightening peels to prevent complications from energy-based or chemical-based treatments.  Best, Dr. Emer.
