I had always, whether summer or winter, greater perspiration stains under the arms. Not anymore! Apply directly the morning after the first time was the axillary region dry and no smell! Every 5 days the evening very little reloading and done! I have some sensitive skin, so may one day prior to application and mind. A day later not shave underarms and it is in the evening a little uncomfortable after the application, but I wear then under the arms a relatively narrow sleeping shirt, then it goes well !
