Trying a new skincare product should not feel like placing a bet on whether your face will cooperate. Yet that is how it feels when several products have disappointed you in a row.
The problem with changing too much
When you introduce multiple products together, even a useful reaction becomes hard to interpret. You are left with a mystery instead of a lesson.
Make the test boring on purpose
Keep the rest of the routine familiar. Introduce one change, use it consistently, and pay attention to the full experience rather than one exciting first use.
Judge the relationship, not the launch
A product should still make sense after the novelty wears off. Does it perform its job? Does your skin remain comfortable? Does it fit the routine you can actually maintain?
The bottom line
The safest way to test skincare is not to become afraid of products. It is to make each change teach you something.
