Agree on the sunscreen also. Those who never got into tanning also seem to age better.
And this. I can't believe the price of some products when you read their ingredients and discover they're just a basic moisturizer. You're often paying for brand/packaging.before putting anything on your skin check out product reviews on makeupalley.com and try to find out more about the active ingredients.
I got obsessed with cosmetic labels a few years back & educated myself on what all those long, clunky words mean, and now I can make a quick estimate of whether a product is worth the price or not. I have a strong need to understand something before I'll accept its claims, especially if that something is expensive, and research has more than once prevented me from wasting my money.
