One of the most important tips for a thrifty shopper to know when they enter a semi-overwhelming beauty store like Sephora is how they can focus on finding the products that are right for them. Thankfully, Sephora lets you grab up to three samples — though there isn't consensus that this is the hard limit — within each "world" or department, as in three perfumes, three items from the "color" world, or three of any packaged samples which brands invariably send to the store, according to a former Sephora employee who spoke with Byrdie.
In general, buying a full-size container of a product you've never tried is a big bet, and it might create waste or have you forcing your face into something that doesn't feel good. Luckily, Sephora has a 30-day return policy, which is valid as long as you haven't used up half of the product. That's right; you can try it multiple times, which is what it may take to realize it's the wrong fit for you.
