A chan\u00adge often beco\u00admes noti\u00adceable within the first week, and for some peo\u00adp\u00adle only over the cour\u00adse of about two weeks.

Obser\u00adva\u00adtions like the\u00adse make the result easier to dis\u00adcuss than the expec\u00adta\u00adti\u00adon that the skin must be per\u00adfect\u00adly dry at all&nbsp;times.<\/p>\n<p>You can usual\u00adly return to your nor\u00admal acti\u00advi\u00adties straight away.
