Because I’m so particular and OCD about reviewing products based on their ingredient lists before actually trying said products, I don’t have to test them for too long before deciding whether or not they’re suitable. I will typically try a new product for two weeks to determine if it fits into my routine and that it doesn’t trigger any negative reactions. Now, I’m very satisfied with my current routine because there are ingredients present that address virtually every problem or issue I have and will encounter. Therefore, the only reason why I’d switch out a product is if I think I’ve discovered something even better.
First, I identify what category of product I’m trying to find substitute. For example, the sunscreen, retinoid, or antioxidant serum.
Second, I make sure that for the two weeks of testing, the rest of my routine remains exactly the same. Think of it as a psuedo-scientific experiment: I try to keep all variables the same (dependent variable), and isolate/change a single variable (independent variable) that I’d like to investigate and improve.
Third, I apply the current product on the left side of my face, and the new product on the right side. I do this for two weeks. If the new product triggers a negative reaction, I discontinue use until said reaction is gone. Then I try the product again to see if I can replicate the same negative reaction. Obviously, if the negative reaction comes back, I throw the new product out. If it doesn’t come back, I continue with the two weeks of testing.
Finally, at the end of two weeks, I evaluate if there is a noticeable difference between the left and right sides. Obviously, if one side of the face has a noticeably positive difference, I will go for the product that was applied to that side. If however, and this occurs more frequently than nought, both sides appear the same, I will ultimately have to go back and consider the evidence, the ingredient list. If I still can’t decide which product I prefer based on merit alone, I factor in other aspects such as cost, ease of acquisition, and texture.
How do you guys go through this process? Is it as intense as mine? Let me know down below!
