A method for treating skin, comprising the sequential steps of:
- a) applying to the skin a first dermatological liquid composition comprising an effective amount of at least one acid, about 0.1% to about 10% of at least one surfactant/emulsifying agent and a cosmetically acceptable vehicle, wherein the pH of the first dermatological liquid composition is between about 2.5 and about 4;
- and thereafter
- b) neutralizing the first dermatological liquid composition by applying to the skin a second dermatological liquid composition comprising at least one alkaline agent suitable for use in a skin care composition, about 0.1% to about 10% by weight of at least one surfactant/emulsifying agent and a cosmetically acceptable vehicle, wherein the pH of the second dermatological liquid composition ranges from greater than about 7 to about 12,
- wherein each of the first dermatological liquid composition and the second dermatological liquid composition has a viscosity of about 1 cps to about 500 cps.
