4 seborrheic keratoses with similar size and thickness on the patients face are randomly chosen and numbered from 1 to 4 and written on a set of cards ;treatment modalities are also randomly named A,B,C or D and written on another set of cards.A blinded person chooses a number from 1 to 4 from the first group and a letter from the second group representing the treatment modality.Assessment of the final results is done by 2 dermatologists who are unaware of the treatment used for any of the lesions and is based on the photographs .</study_design>

      <hc_freetext>seborrheic keratosis.</hc_freetext>
      <i_freetext>Intervention 1: Control group 1: Electrodessication with the same parameters on seborrheic keratosis lesions. The electrodessication (electrosurgical unit, MEG1, Iran Kavandish System co, made in Iran, 2013)  is performed by the mode of biterminal monopolar on seborrheic keratosis lesions with the same parameters and with low energy in one treatment session. Intervention 2: Control group 2: Cryosurgery with the same parameters on seborrheic keratosis lesions. In all patients, cryotherapy is performed with the application of liquid nitrogen with an open-spray for a single 10 to a 15-second freeze-thaw cycle and in one treatment session. Intervention 3: Intervention group 1: Er: YAG laser with the same parameters on seborrheic keratosis lesions. The next device used is Er: YAG laser, LOTUS II erbium device (LOTUS II; Laseroptek Co., Ltd., Sungnam, Gyenggido, Korea). We applied the energy of 500 MJ, with a spot size of 4 mm. All lesions were treated in one session and they received the same amount of energy, fluence, pulse duration, and spot size. Intervention 4: Intervention group 2: Co2 laser with the same parameters on seborrheic keratosis lesions. The CO2 laser used in the study is a fractional CO2 laser (Mixel; Hironic Co., Ltd, Korea). We applied the energy of 1.5 J / cm2, pulse duration of 0.4 sec and spot size of 4 mm.  All lesions were treated in one session and they received the same amount of energy, fluence, pulse duration, and spot size.</i_freetext>

      <results_IPD_description>What will be shared:
All collected demographic data and primary and secondary outcomes are going to be shared after  de-identification of the participants.

When:
These data files will become available starting 6 months after publication.

To whom:
The deidentified IPD and additional supporting information/documents will be available for people working in academic institutions.
