How Soon Can I Start Treating a Bad Chemical Peel?

If you do a few microdermabrasions, that should help even out the little color changes you have since you weren't available to see your derm doc for prescription creams.  Also a couple of light jessner's peels would do the same thing.

Sorry for the issue of uneven blotching of the peel you received. I would use only local care as creams or lotion that heal and bleach. Do not do any more aggressive therapies like re peels.

Another peel is not appropriate at this time, and further sun exposure will worsen or prolong the recovery. Avoid any microdermabrasion too.

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.

The most important concern with uneven appearance in skin healing is infection. Your skin is extremely vulnerable after any resurfacing procedure, including chemical peels. Viral, bacterial, and fungal infections are potential complications. Inform you physician immediately if any areas appear infected.

Follow your skin doctor's post peel guidelines, and speak with him/her regarding this issue as soon as possible.
