[Comparative study of the efficacy and tolerance of 12% glycolic acid cream and 0.05% retinoic acid cream for polymorphic acne].
Topical retinoic acid has demonstrated its efficacy in acne. Glycolic acid has also keratolytic action and could be interesting to treat acne.


OBJECTIVE
To evaluate the efficacy and safety of topical glycolic acid (Glyco A 12%) and retinoin acid (Kefrane 0.05%) on facial acne lesions.


METHODS
It was a randomised double blind study of 40 patients, divided in 2 groups, 20 receiving GlycoA cream (Group A) and 20 receiving Kefrane cream (group B). Medical exam was realised by the same physician at day 0, 21 and 45. The improvement of acne as well as side effects were assessed by both the physician and the patients themselves.


RESULTS
2 patients developed severe eczema of the face and were excluded (one from group A and one from group B). 22 patients followed totally the study. 90% of group A and 83.3% of group B patients improved significantly their lesions. A comparative tolerability was observed for both groups.


CONCLUSIONS
Glyco A cream could be a good treatment for acne even in dark skin patients.
