The present disclosure relates to an acetylcholine receptor-binding peptide and, more particularly, to novel peptides which exhibit a wrinkle amelioration effect by binding the peptides to an acetylcholine receptor on which acetylcholine acts, thereby blocking secretion of acetylcholine. Peptides according to the present disclosure suppress secretion of acetylcholine by having a high binding strength with the acetylcholine receptor, thereby strongly binding the peptides to acetylcholine. Therefore, a cosmetic composition and a pharmaceutical composition comprising the peptides according to the present disclosure as an active ingredient exhibit an excellent wrinkle ameliorating effect.
