The invention discloses a cosmetic composition capable of improving closed acnes and a preparation process thereof, and the composition comprises the following components: butanediol, betaine salicylate, ethyoxyl diethylene glycol, 1, 2-pentanediol, 1, 2-propylene glycol, 1, 2-propylene glycol, 1, 2-propylene glycol, 1, 2-propylene glycol, 1, 2-propylene glycol, 1, 2-propylene glycol, 1, 2-propylene glycol, 1 The acne-removing mask is prepared from 1, 3-propylene glycol, trehalose, hydroxyethyl urea, capryloyl glycine, capryloyl salicylic acid, acne-removing essential oil, glycerol caprylate, allantoin, dipotassium glycyrrhizinate, disodium ethylene diamine tetraacetate, sodium hyaluronate, hydroxyphenyl propionamide benzoic acid and deionized water. The active components for improving the closed comedo comprise capryloyl glycine, betaine salicylate, capryloyl salicylic acid and acne-removing essential oil, and the most direct effect on solving the problem of the closed comedo is to inhibit propagation of propionibacterium acnes; the salicylic acid derivative capryloyl salicylic acid, the betaine salicylic acid and the capryloyl glycine are combined to jointly inhibit reproduction of propionibacterium acnes, so that a very good antibacterial effect is achieved, and the composition can mildly and effectively resist closed comedo, so that the skin is smooth and fine.
