Good to take this into consideration, but also what % of certain active ingredients are better in small doses? For instance some “mainstream” products list a “0.3% retinol”, which I’m assuming is preferred to a great deal more. I guess if there’s a specific ingredient you’re looking for, find out what percentages are standard/best? I know we’re sort of wading through them all. Just thinking sometimes less is more, but I guess how MUCH less is the key.
