Honestly, as someone who didn't wear any makeup for years and now wears it daily, even if your makeup is totally fresh, everyone should bear in mind that it's all full of chemicals and also mineral ores of every kind, that can be extremely drying on delicate skin, if not downright harsh.
If you are wearing makeup of any kind, you owe it to your skin to thoroughly remove it as soon as you are done for the day and to use plenty of nourishing skincare packed with moisture and anti-oxidants. They don't have to be costly - there are plenty of fruits, veggies and oils that are absorbed through the skin, though they might not do some of the more targeted things like the tech stuff does. I definitely see the toll especially on the skin around my eyes, after I started wearing makeup regularly, but it's nothing I can't keep under control if I make sure to soothe and pamper it to balance things out.
Be good to yourself!!
Agreed. You only have one skin. Old cream products on skin = wrinkle galore in the long run
But everyone has the right to make their own decision.
