I did get my cosmelan 1 mask yesterday and Nurse Practitioner applied only the 1/2 jar of cosmelan 1 yesterday and instruct me to wash the mask off after 7 hours. Also I got cosmelan 2 cream to apply at home. She told me we will use the other 1/2 of the cosmelan1 in 3 month. Do I need to get this touch up cosmelan1 sooner?
