Your skin should recover, but may take months. You can try lighter superficial peels such as AHA peels or Jessner's peels done by a licensed Aesthetician or Physician in a Docotrs office. You should not do another 30% TCA on your tummy. I recommend that you try using Retin-A mixed with Hydroquinone 4% once a day for a few months combined with an SPF 30 or higher. Avoid direct sun exposure. Make sure to discontinue the use of products 3-4 days prior to having another treatment done. While your skin may be dry, scaly, scabbed or peeling, avoid picking it before it's ready to come off. This can cause your skin to become darker or discolored.
