Introduction: Aging is considered to be a set of inevitable and irreversible physiological changes. Several techniques have been used with the aim of slowing down and even reversing this process. Objective: To compare the efficacy and local side effects of two phenol-based formulas: the Baker-Gordon formula and the Hetter formula. Methods: Seven pacients were included in a split-face comparative study. The Baker-Gondon and the Hetter formulas were applied on the right and left facial sides respectively. The pain felt during the procedure and intensity of clinical changes in the period following the peeling were measured through a 3 degrees subjetive scale, for each side of the face. The clinic results after 6 months were evaluated by patients and the doctor Who performed the procedures. Results: The pain intensity during the procedure was equivalent for both formulas. With the Hetter''''''''s formula the skin''''''''s integrity was restored more quickly and the undesirable effects were of lower intensity. Regarding the final clinical results two patients preferred the Baker-Gordon formula, one gave preference to the Hetter''''''''s formula and for 4 patients the results were unconcerned. In the medical evaluation, 5 patients had similar results on both facial sides , while 2 presented better clinical results with each formula, respectively. Conclusion: The Gordon-Baker and the Hetter formulas are equivalent for the treatment of facial rhytids.

Ascher syndrome (AS) is a rare disorder of unknown etiology characterized by the presence of double upper lip, blepharochalasis and nontoxic goiter (complete AS). The nontoxic goiter is present in 10-50% of cases (incomplete AS). Trauma, hormonal dysfunction, autosomal dominant inheritance, defects in elastic fibers and allergy are possible causes. Surgery is indicated due to the compromise of facial aesthetics, trauma, or visual difficulty, and to restore the patient's quality of life. The present article reports the case of a patient with a double and blepharochalasis lip, diagnosed as a bearer of the incomplete Ascher syndrome, and describes the adopted conduct.
