Introduction: The splines are dermal parallel linear macroscopically apparent scars associated with the atrophy of the epidermis. A desfigurante and aestética condition of skin; if present as splines rubras, who are recent, and the psychological comimpacto white striations in patients and without therapeutic options for effective reversal. Objective: To assess randomized clinical tests to demonstrate therapeutic effectiveness of protocols used in dermal splines. Method: Searches of major studies in electronic databases (BVS; MEDLINE/PubMed®; EMBASE; LILACS; Cochrane Library), with search strategy through the following descriptors indexed (DeCS and MeSH). Results: Fourteen manuscripts met the eligibility criteria, but without fully effective results. Limitations in the studies are related to the limited number of patients and high-risk or risk of bias uncertain. Conclusion: More detail and clarity in trials are necessary for more consistent decisions.
