How to turn off Browsersync caching?

Question

caching

When you run Gulp, the website opens with the old design, while not having certain changes. If you run directly without Browsersync, everything is displayed correctly. Can you tell me how to disable caching?
gulp code:

(function (r) {
    "use strict";

    // Module includes
    var sass = r("gulp-sass"),
        gulp = r("gulp"),
        browserSync = require('browser-sync').create(),
        // Source folder for SASS
        sourceSASS = "scss/**/*.scss",
        // Destination folder for SASS
        destSASS = "stylesheet";

    // Compiling SCSS to SASS
    gulp.task("sass", function () {
        gulp.src(
            sourceSASS
        )
        .pipe(sass(
            {"bundleExec": true}
        ))
        .pipe(gulp.dest(destSASS))
        .pipe(browserSync.reload({
            stream: true
        }));
    });

    // BrowserSync
    gulp.task('browserSync', function () {
        browserSync.init({
            open: 'external',
            // host: 'local.project.com',
            proxy: 'local.project.com'
            // port: 8080
        })
    });

    // Watcher
    gulp.task('watch', ['browserSync', 'sass'], function () {
    // gulp.task('watch', ['sass'], function () {
        gulp.watch(sourceSASS, ['sass'], browserSync.reload);
        // gulp.watch('app/*.html', browserSync.reload);
        // gulp.watch('app/js/**/*.js', browserSync.reload);
    })
}(require));
