"So it goes with overthinking—or, more accurately, not overthinking." - so it goes with X = the same is true with X = the same logic (i.e. what was just mentioned) applies to X. So the writer is saying that the same logic he/she was explaining using the Maybelline ad (that what strikes you as the most plausible is usually the correct answer) also applies to overthinking. Overthinking (thinking too much, going beyond the simple and obvious) is the opposite of what the writer was talking about. They're saying the answer can usually be gotten simply and intuitively without overthinking, and to drive this point, they add 'or, more accurately, not overthinking'. The last part stresses that what the writer is proposing is NOT overthinking, in case the reader get the wrong idea that they are a proponent of it (because people might mistakenly take the key phrase (overthinking), rather than the negative of it (not overthinking), as what's recommended).

Here if you see. The main emphasis is being given to Maybelline Products.The Slang given here is Maybelline is an Awesome product and actually no one should have doubt in it.. Now coming to your question : It goes with Overthinking , meaning it starts with little Overthinking ( what should be the product name , which product is this ) , but suddenly it strikes that Definately it should be Maybelline As no other products stands in between ( for this the writer had written "more accurately not Overthinking " . Hope this helps. Sorry for typo. Writing in big screen with small fingers 😂
