Uneven Results from a Chemical Peel?

Uneven redness and healing is not uncommon after chemical peels.
Different areas of the face and neck heal at varying rates, largely based on the thickness of the skin. Thicker skin of the nose or forehead may recovery much faster than the thin skin of the lower eyelids.
In addition, different areas of the face & neck area have received different degrees of sun damage. Areas of more sun damage will appear more red and irritated during the recovery period following a peel.
Although uneven application of a chemical peel might possibly result in an uneven cosmetic outcome, it's unlikely with medium/superficial peels. The lower strength peel you received makes any uneveness once all healing is complete more unlikely.
The most important concern with uneven appearance in skin healing is infection. Your skin is extremely vulnerable after any resurfacing procedure, including peels. Viral, bacterial, and fungal infections are potential complications.
Inform you physician immediately if any areas appear infected. Follow your doctor's post-peel guidelines, and speak with him/her regarding your concern.

Thank you for your question! It must take around one month to see the results of your peel. Uneven redness and healing is common after chemical peels. Different areas of the face and neck heal at varying rates, largely based on the thickness of the skin. Thicker skin of the nose or forehead may recovery much faster than the thin skin of the lower eyelids. In addition, different areas of the face & neck area have received different degrees of sun damage. Areas of more sun damage will appear more red and irritated during the recovery period following a peel. I would encourage you to be patient and wait for a few weeks. Use mild products on your skin and avoid the sun.  You can always visit your dermatologist in one month for assessment. Best of luck!

It can take one month before you see the results of your peel.  The areas that had more sun damage can be more inflamed and take longer to heal.  Use mild products on your skin and avoid the sun.  See your dermatologist in one month for assessment.  You may require more than one peel.

It is way too early to make that determination. The results from the chemical peel are often not seen for at least a month. In addition, sometimes more than one peel is required. I would wait at last a month before being concerned whether this peel did or did not work for you.

Just because one side of your face/chest is more inflamed than the other following a peel does not necessarily mean the tech did anything wrong. Sun-damaged skin in general will react more briskly with redness and even crusting. The degree of sun-damage to our skin is almost never totally symmetric. For example, people almost always have more sun damage on the left side of the face because of the sun exposure due to driving. I would encourage you to wait until the peeling has been completed and the skin has fully healed, then re-assess. If you are still dissatisfied, return to the office that treated you with the TCA peel. Healing incidentally does occur much faster with frequent application of bland moisturizers, e.g. Cetaphil or Aveeno.
Good Luck.
