One of the biggest mistakes you can make as a beauty consumer is automatically buying something without really trying it out first. In my experience, this particularly applies to complexion products like foundation and concealer, as well as all types of skincare products. Something that I really love about being a frequent Sephora shopper is that they offer a really generous sample program. I have asked them for samples of foundations and skincare so that I can try them out for about a week and see if I actually love the products further than just a swatch on my hand in the store. This helps to ensure that the colour match is perfect and that the products are actually compatible with my skin type.
