You keep on waiting and waiting

Of course, there won't be any instant changes in your face when you've just started your routine. It's not magic, you've got to wait for the product to do their job... But if weeks and months have gone by and you're not seeing any changes, it might be right to suspect the product's effectiveness. Anti-wrinkles and dark spots might take more time, but effective acne products, and moisturizers should show results within a few weeks.
