I have acne scars to my chin and lots of wrinkles above my lip. Would co2 laser or a TCA peel be better for tackling my problems

A combination of chemical peels and injections of hyaluronic fillers will improve these lip lines as well.  The peels and topical retinoids will improve your skin texture and tone and lines.  The fillers will help fill in the deeper lines aloe the lips.  Chemical Peels or Fraxel will help repair the skin and brighten your whole face. Please consult an expert in cosmetic injections and procedures for the best results. Best, Dr. Green

In the context of peels, sure a TCA with Jessners can help. Spot TCA can be used for deep scars like pick - Ice Pick scars. Given the static photo, CO2 either fully ablative or sessions of CO2 Fractional can help.  
Acne scar revision is a sub-specialised field. For the best results, one should target the acne scar type with ideal treatments and NOT just devices. 

For example deep ice pick scars, and narrow box-car scars can be treated with TCA CROSS peels, mixed scars, rolling, and atrophic scars treated with fractional devices such as Fraxel, fractional lasers, and radiofrequency. Atrophic scars (depressions) can be treated with either fat grafts, or dermal fillers. Tethered and anchored scars are best treated with surgical techniques such as subcision. Other surgical techniques that we use include punch elevation, surgical elevation, punch excision and traditional excision of focal scars. Devices should be viewed as tools to get the job done, and NOT as standalone modalities. 

 

The majority of patients will have a collection of different scar types, and hence a tailored treatment METHOD will be best. Careful examination, especially under angled lighting with scar mapping will give you an understanding of what are the best options for your scars. In the majority of patients its finding the correct combination that give you best results, and everyone is unique! All the best,
