Topical clobetasol in conjunction with topical tretinoin is effective in preventing scar formation after superficial partial-thickness burn ulcers of the skin: A retrospective study.

ABSTRACT

BACKGROUND: Deep erythema and inflammation after re-epithelialization of superficial wounds is a sign of scar formation. Corticosteroids may prevent scarring by suppression of inflammation and fibroblast activity. Tretinoin may increase the efficacy of corticosteroids in this setting. OBJECTIVE: To evaluate the efficacy of corticosteroids plus tretinoin for prevention of scars after superficial wounds. METHODS: In a retrospective study of patients with superficial partial thickness thermal skin burn, we compared the patients who received clobetasol plus tretinoin after re-epithelialization with patients who did not receive any medication. Clobetasol propionate 0.05% ointment was used twice daily with overnight occlusive dressing in conjunction with twice weekly topical tretinoin 0.05% cream. RESULTS: Among 43 patients who had light pink or no erythema after re-epithelialization and consequently did not receive clobetasol + tretinoin, no scar was developed. Among patients who had deep erythema after re-epithelialization, rate of scar formation was significantly higher in 14 patients who did not receive clobetasol + tretinoin than in 21 patients who received clobetasol + tretinoin (64% and 19%, respectively; p = 0.01). CONCLUSION: Clobetasol + tretinoin can significantly decrease the incidence of scar formation in patients with inflammation after re-epithelialization of superficial wounds.
