If you feel like there's something wrong when putting on makeup that wasn't there before, there probably is. When your skin is smooth and hydrated, your makeup looks and feels best. But if the canvas is acting up (you know, with flakes, dry patches, blemishes, pigmentation), then that's a sign that your skin care routine is doing you more harm than good.

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.
