Let's be real for a second. Every year, around mid-September, the beauty world starts vibrating with this weird, frantic energy. It’s the advent calendar rush. Specifically, everyone loses their minds over the 25 days Sephora advent calendar. You've seen the TikTok unboxings. You’ve seen the "is it worth it?" Reddit threads that spiral into 400-comment debates.
But here’s the thing. Most people buy these things for the dopamine hit of opening a tiny cardboard door every morning, and they don't actually look at the math. If you're dropping over a hundred bucks on a box of samples, you better be getting more than just a cute countertop decoration. Honestly, the 25-day version—often labeled as the "Sephora Favorites" collection—is a different beast entirely compared to the smaller, brand-specific ones. It’s a curated chaos of high-end minis and full-sized surprises that usually sells out before you've even bought your first pumpkin spice latte of the season.
What actually comes in the 25 days Sephora advent calendar?
Look, Sephora doesn't just throw random clearance items into these boxes. Well, usually they don't. The 2025/2026 iterations have leaned heavily into "Clean at Sephora" hits and viral sensations. We’re talking about brands like Glow Recipe, Laneige, and Drunk Elephant.
In the most recent versions, the value proposition is wild. You might find a 15ml Sol de Janeiro Brazilian Bum Bum Cream tucked behind door number four, followed by a full-sized Tower 28 lip jelly a few days later. It’s this mix of "I’ve wanted to try that" and "I actually use this every day" that makes the 25-day count so much more satisfying than the 12-day versions. Twelve days feels like a teaser. Twenty-five days feels like a lifestyle overhaul.
The price vs. value trap
You’re usually looking at a price tag somewhere between $90 and $110 USD. Sephora loves to claim the "retail value" is upwards of $300 or even $400. Is that true? Technically, yes. If you bought every single travel-sized serum and mini mascara individually, you would absolutely go broke. But nobody does that. The real value is in the discovery. If you find two new "holy grail" products among the 25 items, the calendar has basically paid for itself. If you end up hating 20 of the items, you just bought a very expensive cardboard box.

Why the 25 days Sephora advent calendar keeps selling out
It's scarcity. Pure and simple. Sephora isn't stupid; they know that by limiting the stock of the "Favorites" calendar, they create a secondary market of FOMO.
I’ve talked to floor leads at Sephora locations in New York and Boston, and they all say the same thing. The minute those boxes hit the floor, they’re gone. It’s not just teenagers either. It’s collectors. It’s people who want to break the calendar apart to use the items as stocking stuffers for five different friends. It’s a smart move, honestly. You buy one 25 days Sephora advent calendar, keep the stuff you love, and suddenly you have "free" gifts for your sister, your coworker, and your mail carrier.
Timing is everything
If you're looking for this thing in December, you're already too late. You’ve lost. The 25-day calendars typically drop in late September or the first week of October. By the time Black Friday rolls around, you’re usually looking at "Out of Stock" notices or marked-up listings on eBay from resellers trying to make a quick fifty bucks.
The common complaints nobody mentions
Not everything is glitter and gold. One big gripe? Repeat products. If you’ve bought a Sephora advent calendar in the last three years, you probably have enough Milk Makeup Hydro Grip Primer minis to coat a small aircraft. There is a certain amount of redundancy that creeps in.

Also, let’s talk about the "filler" days. You know the ones. You open a door on December 14th and it’s... a hair tie. Or a single-use eye mask. It feels like a slap in the face when the day before was a luxury perfume sample. But that’s the gamble. The high-value days (usually the 1st, the 24th, and the 25th) are meant to balance out the "cheaper" days.
- The 2025 Trend: More hair care and wellness. We're seeing fewer eyeshadow singles (thank god) and more scalp scrubs and "inner beauty" supplements.
- The Sustainability Issue: People are getting louder about the packaging. It’s a lot of cardboard and plastic for a few ounces of product. Sephora has started making the boxes "reusable," but let’s be real—most of them end up in the recycling bin by New Year's Day.
How to actually get your hands on one
Don't just walk into a store and hope for the best. That’s a rookie move.
First, you need the app. Turn on notifications. Sephora usually gives "Rouge" members (those who spend way too much money there) a 24-hour head start. If you aren't a Rouge member, you’re fighting for the scraps.
Second, check the "Beauty Offers" section. Sometimes they bundle the calendar with a gift-with-purchase, which is just peak efficiency.

Third, if you see it online, buy it. Don't "think about it." It’ll be gone while you're debating whether you really need another mini mascara. You don’t, but that’s not the point.
A quick note on the "After Christmas" sales
Sometimes—and this is a big sometimes—the leftover calendars go on sale for 20% or 30% off after December 25th. If you don't care about the "advent" part of the advent calendar, this is the ultimate pro tip. You get all the same products for a fraction of the cost. The 25-day countdown is just a suggestion, anyway. Opening all the doors at once on December 26th is a chaotic, beautiful way to spend a Tuesday morning.
Is it better than the competitors?
The beauty advent calendar space is crowded now. Ulta has theirs, Cult Beauty has a massive one, and even brands like Charlotte Tilbury have gone all-in.
The 25 days Sephora advent calendar usually wins on brand variety. While a Charlotte Tilbury calendar is great if you love that specific brand, the Sephora version gives you a taste of the entire store. It’s the "sampler platter" of the beauty world. If you’re a brand loyalist, go with a single-brand calendar. If you’re a beauty polygamist who wants to try everything at once, Sephora is your best bet.
Actionable steps for the 2026 season
If you’re serious about snagging one of these, you need a plan of attack. It’s not just a purchase; it’s a mission.
- Download the Sephora App right now. Seriously. Enable the push notifications specifically for "New Arrivals" and "Back in Stock" alerts.
- Mark September 15th on your calendar. This is the "danger zone" when the first leaks and early drops usually happen. Start checking daily.
- Audit your current stash. Look at what you already have. Do you really need 25 more minis? If your vanity is overflowing, maybe sit this one out or plan to gift the majority of it.
- Set a strict budget. It’s easy to get caught up in the "value" talk and spend money you didn't plan to. Decide now if $100 for a box of samples fits your holiday spending.
- Check the "Favorites" vs. "Collection" labels. The "Sephora Collection" (their house brand) calendar is much cheaper but contains only Sephora-brand products. The "Sephora Favorites" calendar is the one with the big-name brands everyone wants. Don't mix them up in your excitement.
