Sensitive-skin people: what product took you the LONGEST to realize was causing your problem?
I work with sensitive and eczema-prone skin, and one thing that always fascinates me is how often the culprit isn't the product someone suspects.
Sometimes people eliminate their moisturizer or cleanser first, while continuing to use something like a hair product, lip product, sunscreen, essential oil, "natural" product, or even something that never gets applied directly to the irritated area.
And then there's the other tricky part, fragrance-free doesn't necessarily mean your individual skin will tolerate it.
So I'm curious...
What product or ingredient took you forever to figure out was bothering your skin?
And what finally made you connect the dots?
I'm especially interested in the unexpected ones — products you used for months/years before realizing there might be a connection.
