Post-Chemical Peel Precautions

Sun Protection

The American Academy of Dermatology recommends applying broad-spectrum sunscreen with SPF 30 or higher to all treated areas daily, regardless of season, reapplying every 2 hours when outdoors 1, 2
Avoid all unnecessary sun exposure during the healing period and maintenance phase, as even minimal sun exposure can cause repigmentation and worsen outcomes 3, 1
Wear protective clothing including hats to cover treated skin, and use sunscreens containing physical blockers (zinc oxide or titanium dioxide) as these are less irritating to healing skin 1, 2

Use only gentle, pH-neutral (pH 5) soaps and cleansers with tepid water—avoid hot water entirely, and pat skin dry gently with clean, smooth towels rather than rubbing 3, 1, 2
Apply alcohol-free moisturizing creams or ointments twice daily, preferably containing urea (5%-10%) 3, 4

Never use over-the-counter anti-acne medications, topical retinoids, or other skin irritants on treated areas, as this can increase the risk of complications 3, 1, 2
Avoid greasy or occlusive creams that may facilitate folliculitis, and do not manipulate, pick, or scratch treated skin, as this increases infection risk and can cause scarring 1, 2, 5
Avoid chemical irritants including solvents and disinfectants, and do not use hot blow-dryers on treated facial areas 3, 4, 1, 2

Keep hands away from treated areas unless freshly washed, and wear fine cotton clothing rather than synthetic materials that may irritate skin 5, 1, 2
Monitor for signs of infection including painful lesions, yellow crusts, discharge, or spreading pustules, and if infection is suspected, obtain bacterial cultures before starting antibiotics and treat for at least 14 days based on sensitivities 5, 6, 3

Avoid mechanical stress to treated areas (long walks without cushioned shoes, heavy carrying without protective gloves), and shave very carefully if treating facial areas 4, 1, 2
Avoid tight shoes or clothing that creates friction on treated skin 1, 2

Begin intensive moisturization immediately after the peel procedure, and use hypoallergenic moisturizing creams, ointments, and emollients at least once daily 1, 2
Urea-containing moisturizers (10%) are particularly effective for preventing complications 4

Increasing pain, warmth, spreading redness, or yellow discharge indicating possible infection, and development of fever or systemic symptoms require immediate medical attention 5, 6
Excessive inflammatory response, vesicle formation, or blistering beyond expected healing also require medical attention 5, 6

Patients with darker skin are at higher risk for post-inflammatory hyperpigmentation and exogenous ochronosis, and require special precautions and monitoring 5

Underestimating the importance of sun protection leads to treatment failure and repigmentation, and using topical steroids inappropriately can cause perioral dermatitis and skin atrophy 1, 2
Failing to recognize early signs of infection delays appropriate treatment, and resuming harsh skincare products too early disrupts healing 5, 6, 3, 1
