8 Exfoliating Toners to Turn to For the Glowiest Skin

Thankfully, toners, like the rest of your skincare routine, have evolved over the years. Today, many toners are alcohol-free, and instead, are used to refresh and treat the skin before you apply the rest of your serums and creams — without making you extra dry.

One such example is exfoliating toners, which are infused with chemical exfoliants such as AHA and BHA acids, which help to loosen and break up the dead skin cells clogging your pores, while also minimizing dark spots, and improving overall skin texture and tone. These formulas often include soothing and hydrating ingredients to balance out the exfoliation.

“The use of a toner can have the added benefit of mechanical removal of skin debris,” says Dr. Melanie Palm, board-certified dermatologist and cosmetic surgeon in San Diego, Calif. “Simple application of a skincare product such as a serum does not lift off dull skin cells.”

Dr. Palm also notes that a toner can help balance pH level for the skin microenvironment.

When choosing an exfoliating toner, it’s important to consider your skin type and its needs. Dr. Palm says that those concerned with aging can benefit from using a formula with AHAs such as lactic or glycolic acids.

Acne-prone skin can see an improvement with BHAs such as salicylic acid, or a combination of both AHAs and BHAs. As for sensitive skin types, they may fair well with PHA acids, which are larger in molecular size and more gentle on the skin. The same goes for mandelic acid, an ingredient that is great for rosacea or redness.

While an exfoliating toner can be used daily, it’s best to introduce it slowly into your routine to prevent irritation. And if you have sensitive skin, Dr. Palm recommends using a liquid exfoliant once or twice a week at first to gauge how your skin handles it. She adds that if you are using anti-aging products such as retinoids or retinol, gradually start to use the toner over a period of days to weeks. But when in doubt, follow the usage instructions on the back of the bottle.

Finally, don’t expect clear, brighter skin over night.

While you may see some instant improvement, like a bit of a glow, it can take much longer to experience the full benefits of incorporating an exfoliating toner into your skincare routine.

“It takes 30 full days for the epidermal layer of the skin to turn over,” says Dr. Palm. “Therefore, I tell most patients to use a new topical product for two to three months (two to three cycles of epidermal turnover) to gauge response by the skin to active ingredients. However, many patients may notice changes prior to the three month mark.”

It’s an especially good choice for anyone who struggles with post-breakout dark spots and inflammation, thanks to brightening kojic and azelaic acids. While this toner is gentle enough to use morning and night, just make sure you apply sunscreen if you use it in the morning, since chemical exfoliants can cause sun sensitivity. Additionally, Versed is a great option if you’re looking for an effective liquid exfoliant that won’t break the bank — it comes in at under $20.

Mario Dedivanovic’s Debut Line Takes Us Inside The Celebrity Makeup Artist’s Mind

It’s been 20 years since celebrity makeup artist Mario Dedivanovic entered the scene, forever contouring the shape of the beauty world with highlights, shimmers, and perfectly winged liner that launched an army of copycats on social media. 

Now, Dedivanovic, whom the New Yorker recently heralded as “The Makeup Artist at Ground Zero of Internet Beauty Culture,” has taken his years of expertise, massive internet fame, and a few personal checks to labs across the world to create his dream: a self-funded line of products titled Makeup by Mario. 

Welcome to Artist Spotlight #19 series on my blog.

For Dedivanovic, this moment is huge. He begins to tear up on a Zoom call as he discusses the project he began working on three years ago. “I’m just so excited for October 1st”—the launch date, Dedivanovic’s birthday, and the date he began working on the Sephora floor many years ago—“because it almost still doesn’t feel real to me,” he says. 

The artist comes fully loaded with all the bonafides to make a bestselling beauty line. He’s most famous for his work on one of the 21st century’s most famous canvases, Kim Kardashian-West, and helped launch her KKW Beauty line. He’s also had brand partnerships with Laura Mercier and hosts a mega-popular Masterclass. This is the last box to check on his way to beauty moguldom. 

For Dedivanovic, the Sephora gondola, the display for all a brand’s beauty products inside the store, is the ultimate symbol of his success. “I used to manifest into those Sephora bottles when I was cleaning them, that I would one day have that, knowing very well that I had to work very hard and it probably wouldn’t be 20-plus years until I did that,” he explains. “I’ve been dreaming about this moment for a long time.”

His dreams are finally a reality. The new line includes 21 products and tools, including eyeshadow palettes, brushes, and highlighters created to flatter any and all skin tones. “When I work, I tend to like products that I can use on all skin tones,” he says. 

Below, a few beauty tips from the seasoned vet, plus a peek at the products in his collection.

He knows you’re bad at winged eyeliner.

A standout product in the line is the Master Pigment Pro Pencils, inspired by his older sister Vicky, a relatable queen with an inability to work with eyeliner. 

“I think it’s hard even for an artist to really do a beautiful wing,” Dedivanovic says. “I know that a lot of people want to do wings, but it’s challenging and can be intimidating. With this pencil and brush shape, you take the pencil and draw a line from there [the center of your eyelid] to the corner. You stop at the corner and flip the brush over and up and lift. [The brush] literally does the flip for you. I wanted to make this technique very, very easy.”

Dedivanovic added that he will provide new content that inspired tools like the eyeliner and tutorials around how to use it on his social media platforms. 

He likes both contoured and natural makeup.

“I know I’m [known] as the contour king, but I think there was a little misconception,” he says. “I’m not the type of artist that typically will do the heavy stripes and all those types of things. I like makeup to look as if one were born with it in terms of the colors and finishes on the skin. I like it to enhance a woman’s face, not to have it feel unnatural or that they have a ton of makeup on. My goal at the end is that when you are up close, in person, you do makeup to make it look beautiful there. But for me, that’s not enough. I want it to look beautiful for the person as well. Bot in the sense, Oh, wow, your makeup is beautiful. More in the sense of, Wow, you look beautiful.

The brand is for novices and beauty experts alike.

While the line is infused with years of experience from Dedivanovic, he wanted to create something that was easy for the most green of makeup appliers to use. 

Here’s his tip for the Master Metallics palette:

“This is a very creamy formula that’s a blend of powders and creams, so it’s very easy to use with just a swipe of a finger on your lid for a quick application. I wanted to separate my products by texture because as an artist, I was always trained from the very beginning that you always separated your mattes [from] your metallics. That’s the way you packed your bag as well.”

The packaging is the future of beauty.

Dedivanovic was inspired by the iPhone and how easily it can fit into your hand. He wanted the tools to feel accessible and comfortable while you apply your makeup. Think 2001: A Space Odyssey meets BTS’s “On” music video: The full, nearly all-white kit comes in what looks like a briefcase from a space-age population that cracked the code on product design. “It felt like the future of makeup in a sense,” he says. “I hadn’t seen something like this when it was presented. Also, it felt pure.” 

The Master Prep and Set

Available in three different tones—light, medium, and deep—each set comes with six shades to be used as an eye primer. Dedivanovicoriginally tried to get this product in the palettes but couldn’t configure it correctly and inclusion would make the palettes gigantic. Thus, it evolved into its own separate product. 

Buy at Sephora $37

Master Mattes 

The Master Mattes were the first product Dedivanovic began working on in 2017. “The Master Matte palette is inspired by human skin tones,” he explains. “It’s inspired by the technique I have done for many years, in which I shape and contour the eyes using typically different, varying shades of foundation and/or concealer to shape and contour the eyes before I apply eyeshadow.”

To find the right human skin tones for the palette, he researched the different pigments that make up our skin tones. The shades also have a bit of translucency because he prefers subtle to extremely pigmented eyeshadow. 

Buy at Sephora $64

Master Metallic and Master Metals

The all-metallic formula is a creamy blend of both powders and creams, making it very easy to use with a single swipe of your finger onto your lids. Dedivanovic, a self-proclaimed geek, researched the inside of our bodies for the pink, brown, and cream hues. “This is sort of representative of the shades that are within all our bodies on a cellular level,” he explains. “What’s really interesting is when you swatch all these colors together, it’s the epitome of my dream color palette when it comes to shimmery shades.” 

Buy at Sephora $64

If you’re looking for the easiest-to-use product in the collection, this palette is your go-to. But, if you’re looking for more of a high-intensity pigment, Dedivanovic created the Master Metals and Master Metals Manipulator to create your very own dream eye looks. “The idea is that the artist could scrape several shades and mix their own metal shades,” he says. “What happens when you use the Master Metal Manipulator is it turns it into a molten liquid metal. You can do liquid liners with it, you can do a quick all-over eyeshadow shade, or just the inner corner. 

Buy at Sephora $64

Bonus points: The Master Metal Manipulator also turns them into a completely waterproof product. 

Mario’s Master Metal™ Manipulator™ is the ultimate mixing agent for metallic pigments. It instantly transforms loose or pressed metallic pigments into a liquid, creating a gorgeous metal foil. When mixed with pigment, it provides intense grip, lasting power, and locks the formula in place.

Buy at Sephora $18

The Master Crystal Reflectors

The Master Crystal Reflectors come in three shades: quartz, citrine, and bronzite. The reflectors are a few of his favorites because of their sheer finish that “sparkles while dancing on the eyelid.”

The product also reflects light beautifully and gives a bit of reflection and dimension to the eyelid, but can be worn all over the face. “It’s a global exclusive formula, so no one can ever have this formula,” he adds. “I’m very excited about that.”

Buy at Sephora $32

The Master Secret Glow

“For years, I liked to use a highlighter on the cheek or on the eye that is a completely sheer emollient glow,” he says. “I envisioned this even for the girl who really doesn’t wear any makeup. I do clients that have a very natural look and I like natural looks as well. This product really fits both of those.”

Buy at Sephora $29

The Master Tools 

Master Mattes™ Brightening Eye Pencil  

For the collection, Dedivanovic created four pencils and four eyeshadow brushes. According to him, “Pencils are one of the most transformative aspects of makeup, especially when it comes to the eyes.” He incorporated his signature liner techniques into crafting them. 

Buy at Sephora $27

Master Pigment Pro™ Eyeliner Pencil

Mario’s dual-ended liner has all you need to create a precise line. The velvety gel-based formula delivers a full-coverage finish in a single swipe. It has incredible grip after it sets but still allows time to blend, layer, and define. For a soft, symmetrical line, use the brush to smudge and blend.

Master Mattes™ Liquid Eyeliner

This liquid liner is extremely pigmented and features a super sharp, flexible felt tip for ultimate control. The bulletproof formula grips the lid and is completely smudge-proof for bold and lasting definition.

Gentle Makeup Remover Wipes

Last but not least, he created gentle makeup remover wipes. “When I work, I’m very particular with wipes,” he says. “I use them to gently exfoliate the skin right before I go on with skincare.” He wanted to move away from traditional oily formulas so he created something without fragrance or the normal oily residue. “These are made with 100 percent natural, pure cucumber water, and they don’t leave any oiliness.”

6 Skin Care Ingredients You Should Be Using

By now you know the drill: Every few months a new wunderkind skin care ingredient is discovered in some remote locale, and pretty soon it’s everywhere—in your masks, serums, foot creams, insert-step-in-your-beauty-routine-here. But at the end of the day, there are only a handful of ingredients that have stood the test of time and truly become essential. “In skin care, they’re the holy grail,” says Cambridge, Massachusetts, dermatologist Ranella Hirsch.

You’ve probably heard of all these by now. (Retinol, hyaluronic acid, AHAs, peptides, and vitamin C all make the list.) But you may still be a little confused on what exactly each one does—and how you should be using them. Here, I break it all down.

Retinol: For Softening Wrinkles and Fighting Acne

If there’s one ingredient lauded more than any other for its wrinkle-fighting, complexion-perfecting abilities, it’s this derivative of vitamin A. “Here’s the deal with retinol,” explains Hirsch. “We were talking about it in 1975, and we’re still talking about it now because it works.” In study after study, retinol has been shown to build collagen, decrease fine lines, improve skin’s texture, and fight acne.

The prescription version (retinoic acid, or Retin-A) acts fastest, but it’s pricey—and it can be drying. Over-the-counter retinols take eight to 10 weeks to show results (compared with six weeks with an Rx), but are normally paired with anti-inflammatories to calm the redness, peeling, or dryness; they can also cost less than a prescription, depending on your insurance, generally starting around $100.

Whichever type you use, you’ll want to ease into your retinol use slowly. “I start patients on the mildest version, one night a week at the onset,” says New York City dermatologist Amy Wechsler. As your skin begins to tolerate a pea-size amount, you can eventually go up to two nights a week. But stay off harsh physical scrubs and peels while you’re using retinol; remember to moisturize, moisturize, moisturize; and use extra sunscreen for the first six months.

Hyaluronic Acid: For Serious Moisture

This tiny molecule helps lubricate joints and keep skin plump, and is one of the world’s finest humectants (elements that attract and retain water). What does that mean for skin? “Hyaluronic acid is awesome,” says Wechsler. In addition to being a terrific moisturizer, she says, it partners well with other active skin care ingredients (so you can layer it with retinol, for example, and use it daily). “The beauty of hyaluronic acid is that it doesn’t have any fine print,” says Hirsch. “It benefits any skin type, at any age. And the truth is that everyone looks great with hydrated skin.”

Try L’Oreal Revitalift Derm Intensive Hyaluronic Acid Serum $30

Vitamin C: For a Glow Boost

Doctors love vitamin C because it’s an incredible antioxidant and it stimulates collagen production—in other words, it increases glow and evens out spots. For best results, look for a high concentration, up to 20% in a serum or cream.

Vitamin C does have a downside, though: It breaks down when exposed to oxygen and light. Seek out truly airtight packaging, watch out for discolored formulas, and know that because vitamin C loses efficacy in the sun, it’s best as a nighttime product, says Montclair, New Jersey, dermatologist Jeanine Downie. But “use it on the nights you’re not applying retinol,” she adds. It’s also great in an eye cream to help soften fine lines and spots.

Try SkinCeuticals C E Ferulic $166

Peptides: For Firming

“Think of peptides as Legos—they’re protein building blocks,” says Hirsch of the skin strengtheners. Studies show certain peptides can boost collagen production and speed wound healing; or they can mimic the effect of Botox when applied topically. That means you’ll likely want to introduce peptides in your 30s, when you notice your skin doesn’t feel quite as firm or bouncy as it did in your 20s. They can also be used on your body to smooth and firm skin, and they may fade old scars and stretch marks. There’s emerging science that some peptides have been found to safely treat eczema.

Salicylic Acid and Benzoyl Peroxide: For Eradicating Acne

Okay, these are technically two ingredients—but the pair is name-dropped so frequently in the same acne-fighting sentence that it seems a shame to split them up.

“Salicylic acid is a lipid-soluble acid, so it penetrates into oily pores to clean them out, and it’s anti-inflammatory too,” renowned dermatologist Fredric Brandt once told us. “Benzoyl is antibacterial, so together they work synergistically.”

Look for bacteria-zapping benzoyl peroxide in face washes or spot treatments. It’s widely available in drugstores, ranging from 2.5% to 10% concentrations. (To minimize irritation, start with the lowest.) Try salicylic acid in an allover toner or cream to prevent breakouts, or on pimples if you have sensitive skin—it’s gentler than benzoyl, explains Wechsler.

Alpha Hydroxy Acids: For Smoothing

“My patients love, love, love AHAs,” says Downie, who explains that the powerful exfoliators are genius for clearing up sun damage, hyperpigmentation, acne, and fine lines. Multiple AHAs exist, but the most popular (and potent) is glycolic acid, which penetrates damaged skin to spur fresh, new skin cell production. Glycolic acid does its exfoliating work in everything from once-monthly in-office face peels to nightly washes, but it’s best not to use glycolic acid while you’re on retinols. And if your skin is sensitive, try glycolic’s less intense AHA cousin, lactic acid, which also chemically exfoliates but isn’t as drying.
