Standard guidelines of care for chemical peels Standard guidelines of care for chemical peels Member, IADVL Task Force*, Department of Dermatology, Safdarjung Hospital, New Delhi, India or correspondence: Dr. Niti Khunger, Department of Dermatology, Safdarjung Hospital, New Delhi, India. Chemical peeling is the application of a chemical agent to the skin, which causes controlled destruction of a part of or the
entire epidermis, with or without the dermis, leading to exfoliation and removal of superfi cial lesions, followed by regeneration
of new epidermal and dermal tissues. Indications for chemical peeling include pigmentary disorders, superfi cial acne scars,
ageing skin changes, and benign epidermal growths. Contraindications include patients with active bacterial, viral or fungal
infection, tendency to keloid formation, facial dermatitis, taking photosensitizing medications and unrealistic expectations.
Physicians’ qualifi cations: The physician performing chemical peeling should have completed postgraduate training in
dermatology. The training for chemical peeling may be acquired during post graduation or later at a center that provides
education and training in cutaneous surgery or in focused workshops providing such training. The physician should have
adequate knowledge of the different peeling agents used, the process of wound healing, the technique as well as the
identifi cation and management of complications. Facility: Chemical peeling can be performed safely in any clinic/outpatient
day care dermatosurgical facility. Preoperative counseling and Informed consent: A detailed consent form listing details
about the procedure and possible complications should be signed by the patient. The consent form should specifi cally
state the limitations of the procedure and should clearly mention if more procedures are needed for proper results. The
patient should be provided with adequate opportunity to seek information through brochures, presentations, and personal
discussions. The need for postoperative medical therapy should be emphasized. Superfi cial peels are considered safe in
Indian patients. Medium depth peels should be performed with great caution, especially in dark skinned patients. Deep
peels
are not recommended for Indian skin. It is essential to do prepeel priming of the patient’s skin with sunscreens,
hydroquinone and tretinoin for 2-4 weeks. Endpoints in peels: For glycolic acid peels: The peel is neutralized after a
predetermined duration of time (usually three minutes). However, if erythema or epidermolysis occurs, seen as grayish
white appearance of the epidermis or as small blisters, the peel must be immediately neutralized with 10-15% sodium
bicarbonate solution, regardless of the duration of application of the peel. The end-point is frosting for TCA peels, which are
neutralized either with a neutralizing agent or cold water, starting from the eyelids and then the entire face. For salicylic acid
peels, the end point is the pseudofrost formed when the salicylic acid crystallizes. Generally, 1-3 coats are applied to get
an even frost; it is then washed with water after 3-5 minutes, after the burning has subsided. Jessner’s solution is applied
in 1-3 coats until even frosting is achieved or erythema is seen. Postoperative care includes sunscreens and moisturizers
Peels may be repeated weekly, fortnightly or monthly, depending on the type and depth of the peel.
Key Words: Glycolic acid, Trichloroacetic acid, Salicylic acid

Indian J Dermatol Venereol Leprol | Supplement 2008 Khunger N: Standard guidelines of care for chemical peels The concept of peeling the skin to improve the texture, smoothen and beautify it has been used since ancient times. In ancient Egypt, Cleopatra used sour milk, now known to contain lactic acid, an alpha hydroxy acid while French women used old wine containing tartaric acid, to enhance the appearance of the skin.[1, 2] Chemical peeling is a common office procedure that has evolved over the years, using the scientific knowledge of wound healing after controlled chemical skin injury.[3] In spite of the Active bacterial, viral, fungal or herpetic infection advent of newer techniques and lasers, peeling has stood the test of time as a simple procedure, requiring hardly any iii H/O (history of) drugs with photosensitizing iv.
