Effect of pretreatment on the incidence of hyperpigmentation following cutaneous CO2 laser resurfacing.
Dermatologic Surgery : Official Publication for American Society for Dermatologic Surgery [et Al.] 1999 January
BACKGROUND: Transient hyperpigmentation is the most common complication seen following cutaneous carbon dioxide (CO2) laser resurfacing.
OBJECTIVE: The purpose of this study was to determine whether the use of a topical skin lightening regimen prior to cutaneous laser resurfacing reduces the incidence of post-laser resurfacing hyperpigmentation.
METHODS: One hundred consecutive CO2 laser resurfacing patients (skin types I-III) were randomized to receive preoperative treatment with 10% glycolic acid cream twice daily (n=25), hydroquinone 4% cream qHS and tretinoin 0.025% cream twice daily (n=25) or no pretreatment (n=50, control) for at least 2 weeks. Clinical and photographic assessments were performed prior to laser resurfacing and at 4 and 12 weeks following treatment.
RESULTS: There was no significant difference in the incidence of post-CO2 laser resurfacing hyperpigmentation between subjects who received pretreatment with either topical glycolic acid cream or combination tretinoin/hydroquinone creams and those who received no pretreatment regimen.
CONCLUSION: It is postulated that reepithelialization after cutaneous laser resurfacing includes follicular melanocytes that have not been affected by topical pretreatment. When instituted as a component of the skin care regimen postoperatively, topical hydroquinone, tretinoin and/or glycolic acid preparations may be helpful in reducing post-laser resurfacing hyperpigmentation.
