Chemical peels are not suitable for all. The skin burning effect of the acids used in the chemical peel is not suitable for patients with dark-colored skin. Further, this treatment could be devastating for people with freckles. This is predominantly because the chemical peel eliminates the developed freckles as soon as the chemical solution is applied on the face. This makes the treated as well as the untreated areas look extremely different. This method of skin rejuvenation is certainly not appropriate for individuals who wish to eliminate all the spots and patches on the face. Further, it proves to be ineffective to treat areas of the skin other than the face.  Apart from the above conditions, this treatment is not advised to candidates who are pregnant or breast feeding. It is strictly banned for people suffering from cardio-vascular disorders. It shows no results on the skin of the person damaged by pigmentation and scarring. Further, the treatment proves to be futile with patients having loose and sagging skin as it is unable to uplift and tighten the skin. Those who opt for a phenol peel must discuss their medical history with their doctor so as to avoid long term side effects of this skin deep treatment.
