How can I tell if my new product is working?
First, you have to give a new product 60-90 days, unless it irritates you. Change only one product at a time. Make sure the difference you’re seeing isn’t just seasonal or a fluke …..as in you just got back from Hawaii and your skin looks worse/better, etc.
It helps – okay maybe this is a little too scientific – to keep a small notebook and just write the product, start and end date, and your impressions after 60-90 days. One good measure is are you getting more compliments on your skin?
“Selfies” aren’t that helpful because the lightening and angles vary too much to get a good photo.
