6 Sweat-Proof Makeup Hacks From A Celeb MUA That Really Work

How can someone check the expiration date for their makeup?

How many times have you picked up your order from Sephora or Ulta without looking at every detail of your makeup products? We're guilty of being more concerned about adding something to our routine too so don't feel like you're being called out! If you're not 100% sure how to start being mindful about something's shelf life, Prestidge and Healy want to let you in on a little secret.

"It's actually pretty simple. There's something called a PAO symbol, which stands for 'period after opening.' You'll find it on the exterior of makeup products — sometimes on the product itself but always on the box," he says. Wondering what it looks like? Healy says, "The PAO symbol looks like a small jar with a number followed by the letter 'M,' which stands for months. For example, '3M' means three months, '6M' means six months, and '12M' means twelve months."

Prestidge also adds, "Brands often print batch codes that consumers can input into websites like CheckCosmetic to determine the production date." If you've yet to open your product, Healy says "A good rule of thumb is to assume it will last about twice as long. So, if the PAO says '6M,' the product is good for six months after opening and likely up to twelve months if unopened."

Do some makeup products have a longer shelf life than others?

Based on what Healy shares, it's evident different makeup products have longer shelf lives than others, and there are plenty of different factors that determine why. "Products like mascara and eyeliner, which are used around the eyes and tend to be liquids or creams, typically have the shortest shelf life due to their risk of bacterial growth. You should replace them every three months," he says. Excuse us while we collectively clutch our pearls.

Now that we've caught our breath, we can breathe a sigh of relief because Healy says that's the only products we have to replace a little quicker. "Foundation and concealer, which are also liquids, can usually last up to a year. Lipstick is good for about a year, while lip gloss can last around 18 months," he shares. Still, Prestidge feels you should be especially mindful of liquid and cream products because their shorter lifespans are attributed to "their high water content which fosters bacteria."

For those of us who love other face products, we have an even longer time to replace them. "Powders, like brow powders, bronzers, and blushes, have a much longer shelf life — usually a year and a half to two years," Healy explains. Prestidge says this is because "they contain fewer ingredients prone to bacterial growth." And for good measure, Healy shares we can keep nail polish for "three years before it becomes dry and clumpy," and fragrances for "five years before they start to break down."

What are the top signs it's time to replace makeup?

Not always good at keeping track of when you bought your makeup? No worries — there are some key signs you can recognize that your makeup is likely expired. Healy points out you'll be able to see that "the formula may have shifted or separated, or the product may have dried." More often than not, both he and Prestidge agree expired products will often smell rancid. "For example, brow gel can smell musty if it's been sitting unused for a year. If you're unsure, it's better to throw it out," encourages Healy.

Not only that, but Prestidge says to pay attention to your product's color. "If the product's color shifts, it's a a sign it's degraded," she says. Also, your skin will let you know when expired products are irritating it. "If you notice itching, redness, or breakouts after using a product, it might be expired, she alerts.

To avoid this, go an extra step further by using a "label maker to note the purchase date on your products, or keep a record in your phone," suggests Healy. This will help lessen the chance you're using something that's full of harmful bacteria.

What can happen if someone keeps using expired makeup?

There are some things we'd love for you to be rebellious about, but using old makeup isn't one of them. Healy feels the same way and says, "Using expired makeup increases your risk of infection and irritation, which can lead to unsanitary conditions and even bacterial contamination."

The last thing we want is for you to get sick because you didn't want to let go of something. While symptoms may not always be as severe — Prestige says you could see allergic reactions, redness, or acne — Healy reminds us that "at the worst, it could result in serious infections that require treatment." This could look like developing styes or pink eye if you're "using old mascara or eyeliner," according to Prestidge.

Plus, your makeup won't give you the look you're going for if it's expired. "Expired products may no longer perform as intended, compromising coverage, color, or longevity," she says. Healy's ultimate advice? "Always be cautious, check for the PAO symbol, and replace products when needed."

Best Primers For Long-Wearing Makeup Looks

Smashbox Photo Finish Primer

Both Pucker and Cameron recommend this primer because it truly helps makeup stay put all day.

“When I need a primer that won't let me down, whether I'm at an important event or just want my makeup to last all day, this is my first choice," says Pucker. "It's versatile and reliable, the kind of primer I always have in my makeup bag.”

“This primer has a creamier texture, is non-oily and light," says Cameron. "It protects the makeup from starting to run due to sweat. This makes it excellent for occasions, such as weddings or photographs, where you need your makeup to be worn for long periods.”

Hourglass Veil Mineral Primer

This is a great primer for oily skin since it has a slight mattifying element. It primes your face for makeup and makes it stay, all while simultaneously concealing redness, minimizing the appearance of pores, fine lines and wrinkles, and providing SPF 15 protection.

For drier skin that needs some extra love, this Too Faced primer is perfect. It's crafted with coconut water, which hydrates the skin, and probiotics that boost the skin's radiance and elasticity.

B+C Staff Writer, Jasmine, also adores this product.

"It's really great for dry, oily, and combination skin, which explains why my skin feels immediately hydrated after I use it," she writes in her review. "It's also non-comedogenic — giving my pores room to breathe — and it doesn't leave a white cast after it's applied to my face. I'm a brown-skinned girlie, so this is highly important!"

Laniege Glowy Makeup Serum Primer

If glow is what you want, this primer from Laniege expertly primes and hydrates your skin so you have a smooth base to layer on more luminous products. It's formulated with diamond mineral powder, which helps fill in any uneven texture on your face – which is why this is one of my personal go-to's!

1. Full Coverage Foundation

There was a time where wearing full-coverage foundation was all the rage. From drugstore to high-end brands, it seems like they were consistently shoved in consumers’ faces to help us achieve a ‘full beat’ without sitting in a makeup artist’s chair. Also, those of us with dark spots or hyperpigmentation may have relied on them when we were in the thick of our skincare woes.

But these days, wearing too much foundation isn’t as popular as natural and skincare makeup are prioritized. If anything, more people are interested in wearing light-to-medium coverage foundation, skin tints, or tinted moisturizers.

2. Too Much Concealer

It wasn’t until I watched this video by makeup artist Katie Jane Hughes that I realized some of us have been too heavy-handed with our concealers. There’s no reason we should be slapping products under the thinnest parts of our face, but we didn’t know any better!

Now that you know you can still get the desired effect with a minimal amount of concealer, don’t revert back to painting your under eyes!

3. 'Baking' Your Setting Powder

Before you throw away your setting powders, step away from your makeup drawer and have a sit-down chat with me. There isn’t anything wrong with applying them to your face to help ‘set’ your foundation and concealer. However, spending over 10 minutes ‘baking’ your powder (AKA letting it sit untouched) doesn’t work for everyone.

It can lead to creased makeup which can derail your look, plus it’s a pain to correct when you’re halfway through your routine!

4. Overlining Lips

I love a good lip liner, especially if it mirrors my favorite ‘90s makeup look. But, there’s such a thing as overdoing it. The key to lining your lips is following the natural flow of them. Going out of your way to draw above and under your lips’ lines comes off as comical and exaggerated. If anything, use a lip plumping gloss to help your lips look fuller.

5. Overtweezing Your Eyebrows

I don’t even have the words for this outdated makeup look besides wanting to say “no” 20 times in a row. But, I’ll bite and say why this shouldn’t be on your 2025 beauty moodboard.

Some people naturally have thinner eyebrows which is A-okay! However, purposely tweezing your eyebrows to smithereens is cringey. If you truly want to wear this look, here’s what you can do instead of tweezing:

• Create a faux bleached look by applying a skin tone colored setting powder all over your brows.
• Once they’ve ‘disappeared,’ take an eyebrow pencil or eyeliner to draw a thin line over them.

I’m…wondering what the ramifications of telling you how to do this will be, but only use go for this look if it’s a part of a themed party…like Halloween.

6. Exaggerated Highlighter On Cheeks

The shimmery look is in since it’s winter, but please don’t make it look like you dipped your cheeks into a vat of glitter. You can lightly dust highlighter onto your cheeks for a more natural glow that flows with the rest of your look. Otherwise you’ll look like a walking disco ball which could be the opposite of what you were going for.

7. Heavy Contour Or Bronzer

I know the ‘sculpted’ look is popular, but too much contour or bronzer can overpower the rest of your makeup and face. While it’s not impossible to fix if you do it by mistake, using the wrong shade of contour or bronzer may still peep through no matter how much you try to buff it out.

When in doubt, be gentle with your contour or bronzer application!

8. Incredibly Matte Makeup

Matte makeup that didn’t budge was the ‘It Girl’ look for oily and combination skin girls! We thought it was the answer to our skin’s incessant need to hydrate our faces instead of actually using skincare products that focused on combatting that issue (psst…Vitamin C serums help!).

But now’s the time to break up with this look for good for one reason: dewy skin looks healthier.
