11 Products Beauty Pros Really Want You To Stop Using

Some face washes leave your skin positively dewy, while others leave it feeling more like old sandpaper. One shampoo may make your hair look lush and shiny—another, well, you get the picture. And most of time, you only discover which ones are subpar after buying them.So annoying. And expensive. That's why we talked to dermatologists, hair stylists, makeup artists, and nail experts to find out which products aren't doing you any favours—or worse—and what to start using to instead.

Full-coverage foundation

While foundation isn't necessarily bad for your skin, it can look heavy (and even accentuate wrinkles) and usually isn't even necessary.

Switch to: Sheer foundation with spot concealer
"I prefer the look of a sheer foundation paired with a creamy concealer to add the coverage where you need it," says makeup artist Ashleigh Ciucci. "Using these products gives the skin a fresher and more modern look." If you are looking for some hefty coverage to conceal frustrating issues like rosacea or vitiligo, then full-coverage foundation could be a good option.

Discount hair products

We've all seen those high-end hair products lining the shelves at discount stores. But hairdresser Jet Rhys says you shouldn't even think about buying them. "Often, those products have been sitting in warehouses for years, and they are watered down and expired," she explains.

Switch to: Salon-brand products from authorised retailers
If you're devoted to a particular brand, you can only be sure that you're getting the real deal—and something not past its expiration date—when you buy from a professional salon or authorised retailer. Check your favourite brands' websites for a list of sites and stores that carry your go-to products.

Cleansers with sodium lauryl sulfate

Sodium lauryl sulfate (SLS) is a detergent-like ingredient that gives cleansers their lather. Yes, it removes dirt, oil and makeup pretty well, but there's a big downside: "It can irritate your skin and dry it out," warns dermatologist Dr Debra Jaliman. The strong cleansing agent can strip skin of its natural oils, leaving it tight, dry and inflamed.

Switch to: A mild cleanser
Jaliman suggests face washes made with the ingredient decyl polyglucoside. "It's a natural and mild surfactant that cleans the skin, yet maintains balance without causing dryness," she says.

Cuticle cutters

Visible cuticles can cramp your mani style, but they serve an important role. "The cuticle is the nail's protective seal and key to overall nail health," says dermatologist Dr Dana Stern. Cutting or aggressively pushing back your cuticles leaves nails vulnerable to infection.

Switch to: A washcloth or a cuticle pusher
It's okay to clip any hanging, ragged cuticles with a pair of clean cuticle trimmers, but don't snip the rest of your cuticle. When you get out of the shower, use a washcloth or a cuticle pusher to gently push back the skin. Your skin will be super soft from the steam, so this should be a quick and easy task.

Alcohol-based toners to treat acne

Traditional, alcohol-based toners will only dry out your skin, cautions dermatologist Dr Joshua Zeichner. "Oftentimes, adult women with acne actually have dry skin, despite their oil and breakouts," he says. Like SLS, alcohol strips skin of its essential moisture, exacerbating dry skin.

Switch to: Oil-free moisturisers
They provide the hydration you need without the pore-clogging oil. "I find that oil-free moisturisers, alongside acne medications, get better results than the drying effects and barrier disruption associated with harsh toners," says Zeichner.

Bargain blow dryer

It gets the job done, so what's the big deal if it doesn't have all the bells and whistles? Here's the issue: "Basic run-of-the-mill blow dryers take extra time drying your hair and therefore damage it more," explains hairstylist Devin Toth.

Switch to: A tourmaline-infused dryer
Tourmaline emits negative ions that break down water molecules more quickly and efficiently than dryers made without it. That means your hair dries faster and is exposed to less damaging heat in the long run.

Facial scrubs containing walnut shells

Gritty scrubs made with pulverized walnut shells can be really abrasive, causing microscopic tears that leave skin vulnerable to infection and inflammation, says makeup artist Sophia Porter.

Switch to: A glycolic acid exfoliant
The acid gently and safely dissolves away the glue-like substance that holds dead skin cells on your skin, allowing them to be easily sloughed off. No scrubbing, or rough particles required.

Waxy root sprays

Temporary root cover-up products made with waxes are a colourist's pet peeve. "They're hard to remove from the hair and block dye from penetrating," explains colourist Doug Macintosh.

Switch to: Root-covering powders
No need to walk around with visible roots; just switch to wax-free products that won't impede dye molecules from getting into the hair shaft. .

Long-lasting lipsticks

Matte, long-wearing lip formulas tend to be overly drying on lips, leaving them looking and feeling rough—not exactly a look you'd want.

Switch to: Gloss
Lips with a glossy or frosty texture look more kissable and touchable, says Ciucci. Look for a product that also adds hydration.

Anti-frizz serums that contain silicone

Silicone hair products make hair appear smooth and shiny—at first. But they leave behind a coating that can, over time, dull hair and block nutrients from getting into the hair shaft, says celebrity hairstylist Juan Carlos Maciques. Not sure if your go-to products contain the chemical? Check the ingredient panel and look for words that end in 'cone:' Cyclomethicone, dimethicone, and methicone, for example, are all types of silicone, and there are countless others.

Switch to: Lightweight hair oil
A little oil adds sheen, control, and hydration to hair without the buildup.

Nail polishes containing formaldehyde

This noxious chemical alters the structure of the nail plate, making it harder. It also reduces nail flexibility and increases brittleness—a recipe for broken nails—and can cause irritation and separation of the nail plate and the bed (ouch). But a bigger issue? The Department of Health and Human Services named formaldehyde a known human carcinogen in 2011. "It's remarkable that there are still many nail products, especially those touted as 'nail treatments,' that contain formaldehyde," says Stern.

Switch to: Three-, five-, or nine-free nail products
With these formulas, you can rest easy that there is no formaldehyde lurking in the bottle. These products are also free of other potentially harmful ingredients such as toluene and dibutyl phthalate.
