Even though most diehard beauty addicts play the field every now and then to try new creams, serums, lotions, potions, masks, and more (in the name of research, of course), there are a handful of tried-and-true favorites that keep users coming back. And, when it comes to those never-disappointing products, we have pioneers in the skincare department to thank. Over the years, they鈥檝e hit a high note with some of the most influential launches based around advances in technology and development, which is why their lines keep selling out on the reg. Ahead, learn how these nine highly esteemed brands broke into the beauty biz.

Kate Somerville

Between her stunning LA med-spa (thanks to a fireplace filled with crystals and chandeliers everywhere, it feels more like a glam townhouse with treatment rooms than a skincare clinic) and her rapidly growing product line, Kate Somerville is on a roll. But back before she was a household name, there was one product that started it all: the ExfoliKate Intensive Exfoliating Treatment ($24). 鈥淚 was treating people who were constantly asking me to travel with them to keep their skin in shape, and when they couldn鈥檛 take me, I mixed an exfoliating product they could take on the go,鈥 says Somerville. 鈥淓xfoliKate is the next best thing to a facial since we use natural, exfoliating particles like pumpkin, papaya, and pineapple enzymes to lift dead skin cells, as well as lactic acid to dissolve them. After just one use, skin is brighter, smoother, and healthier-looking.鈥

La Prairie

When La Prairie鈥檚 team of uber-smart scientists first discovered the benefits of caviar on the skin back in 1987, their Skin Caviar Dermo Beads were launched, along with a revolutionary delivery system that would forever shape the skincare world. These potent pearls later went on to become the Swiss beauty brand鈥檚 iconic Skin Caviar Luxe Cream ($485), but now it鈥檚 back, remastered, and better than ever with the addition of Caviar Premier. 鈥淐aviar Premier is an advanced new caviar complex where we have enriched our natural caviar extract with a mix of biomolecules (lipids, proteins, peptides, DNA, and carbohydrates), their building blocks (amino acids, nucleotides, and sugars), and minerals obtained from various sources such as yeast, algae, plant, and chemical synthesis,鈥 explains Dr. Jacqueline Hill, director of strategic innovation and science for the brand. Basically that鈥檚 a lot of big words about a powerhouse product that lifts and firms while stimulating collagen growth through the power of caviar. And that鈥檚 why anything that comes in their coveted royal blue bottle is a winner by our standards.

Drunk Elephant

After setting out to eliminate the 鈥渟uspicious six鈥 (essential oils, drying alcohols, silicones, chemical screens, fragrance and dyes, and sodium lauryl sulfate) from her skincare routine, Drunk Elephant founder Tiffany Masterson ended up creating a system of what she calls six core SKUs that make up the perfect skincare solution. A Pekee Bar ($28), Juju Bar ($28), C-Firma Day Serum ($80), Virgin Marula Luxury Facial Oil ($40), Umbra Sheer Physical Daily Defense SPF 30 ($34), and T.L.C. Framboos Glycolic Night Serum ($90) later, her brand remains one of the fastest growing at Sephora. 鈥淭he product line came about by sitting down and defining which ingredients I wanted, then I put pen to paper and created what, as a consumer, I thought the perfect vitamin C looked like and so on,鈥 says Masterson. 鈥淭he system resets your skin to a healthy balanced state by eliminating the root cause of issues 鈥 the suspicious six 鈥 and I only use ingredients that are compatible with high levels of acids.鈥 Not for nothing, but the name and cute colorful packaging also play an important role in our love for DE.

Summer Fridays

If there was ever one product that blew up overnight, it was the Summer Fridays聽Jet Lag Mask ($48). Created by TV-host-turned-lifestyle-blogger Marianna Hewitt and her business partner, fellow lifestyle blogger Lauren Gores, this do-it-all miracle worker relieves stressed-out skin, plumps up fine lines, instantly refreshes, whether you鈥檙e stepping off a plane or waking up in bed after a big night out. Basically, it fixes all of life鈥檚 skincare issues for you. 鈥淢y jet lag life comes from traveling all over the world and having tired, dehydrated skin,鈥 explains Hewitt. 鈥淥ften I would take a red-eye, land, and go straight to a photoshoot, so I didn鈥檛 want my skin to look as tired as it felt. We wanted to create a product that would give skin an instant glow.鈥 Consider that mission accomplished. Another plus? It鈥檚 safe for pregnant women, since Gores was pregnant at the time they were testing the JLM and looking for both clean and effective products. The Jet Lag Mask鈥檚 success has been so insane they just launched a follow-up product, the Overtime Mask ($44), that鈥檚 their pumpkin and exfoliating apricot seed powder solution for luminous skin. (And yes, it smells divine.)

Sunday Riley

It seems like everyone has heard of Sunday Riley鈥檚 Good Genes All-in-One Lactic Acid Serum ($158). When discussing how her bestselling formula came about, Riley says: 鈥淚 believe everyone needs an alpha hydroxy acid, retinoid, and vitamin C in their regimen, and lactic acid is great because it hydrates, exfoliates, unclogs pores, reduces the appearance of fine lines and wrinkles, and is suitable for all skin types and ages.鈥 Sign us up for all of that. Also worth noting is that Good Genes delivers instant results 鈥 within three minutes, to be exact. Fine lines are reduced, texture is smoothed out, pores are diminished, and you are left with a J.Lo-worthy glow. 鈥淕ood Genes is a wonderful primer too 鈥 I use it every day under my foundation,鈥 adds Riley.

Joanna Vargas

Celebrity facialist and founder of Joanna Vargas Salon and Skincare Collection Joanna Vargas is a skincare goddess in the industry, beloved by celebrities, models, and everyday gals alike. With a roster of celeb clients that reads a mile long and an award-winning product line that鈥檚 consistently seen on every 鈥渂est of鈥 list, Vargas is at the top of her game. And although her current collection includes 17 products in total 鈥 including cult favorites like Super Nova Serum and the Twilight Face Mask 鈥 there was one that started it all, the Daily Serum ($85). 鈥淚 wanted something that really increased circulation and oxygenation and provides intense vitamins,鈥 Vargas says of her firstborn product. 鈥淚 also wanted the product to be universal for all skin types. It was by far the hardest formula to make 鈥 and took over two years鈥 but it is still my top-selling product.鈥 We can see why.

Tata Harper

If you鈥檙e anything like us, you have a lineup of Colombian skincare guru Tata Harper鈥檚 instantly recognizable (and beyond stunning) bottles lined up on your vanity. Seriously, name a more gorge packaging line 鈥 we鈥檒l wait. Yet when Harper was first setting out to develop her all-natural, non-toxic line, there was one product in particular she wanted to focus on: the Hydrating Floral Essence ($89). 鈥淚 wanted a lightweight, fast-absorbing essence to help prep the skin for the rest of the regimen, but I also wanted it to have an obsession-worthy aroma so that the application experience was memorable,鈥 recalls Harper. 鈥淭hat鈥檚 one of the reasons I wanted a mist, rather than an essence that鈥檚 applied to a cotton pad and then to the face.鈥 We鈥檒l thank her for that, because not only is the scent heavenly, but one spritz of this stuff and you鈥檒l feel invigorated and ready to take on the day.

Peach & Lily

K-beauty brand Peach & Lily sold a staggering 100,000-plus sheet masks and sold out within the first week of launch (without any paid marketing) after they debuted their Dream Sheet Mask Collection ($15). And ever since, the world鈥檚 been obsessed. There鈥檚 Good Skin Day Mask to drench and nourish, Reset Button Mask to soothe and restore, and Chubby Cheeks Mask to lift and plump, but founder Alicia Yoon鈥檚 journey to launch these beauty bad boys was unconventional, to say the least. 鈥淥ur Peach & Lily community started asking us if we had our own skincare line and were very interested in sheet masks, so we asked what kind of mask they would want and received thousands of in-depth answers. It took us months to digest the feedback, but essentially, the main requests were for sheet masks that didn鈥檛 have alcohol, synthetic fragrance, or any harsh ingredients while having a lot of high-quality, good-for-skin ingredients,鈥 she says. If you鈥檝e ever tried P&L, you know they are drenched with nourishing ingredients like chia seed, algae, hyaluronic acid, and snail secretion filtrate (their shining star), which is why they cling to your face so well without any tackiness post-application. Verdict? Keep a bunch on hand for a skin pick-me-up whether you鈥檙e on the go or just in your PJs at home.

Orveda

You don鈥檛 always think of 鈥渧egan鈥 and 鈥渓uxury鈥 together, but Orveda founder Sue Youcef Nabi did 鈥 and that鈥檚 how this highly concentrated vegan skincare line and its signature mix of a marine enzymes, natural prebiotic, hyaluronic acid, and bio-fermented kombucha black tea came about. 鈥淥ur very first launch was The Healing Sap ($150),鈥 says Nabi. 鈥淚t鈥檚 a hybrid between a toner that ends the cleansing routine and a serum that starts the treatment routine, but it鈥檚 also a product that can fit anyone鈥檚 skin needs 鈥 25 to 90 years old.鈥 This appropriately dubbed 鈥済low shot鈥 contains all-vegan actives that literally reset your skin鈥檚 glow by boosting hydration levels, improving skin texture and tone (hello, #glassskin), and the best part? The product list of 鈥渇ree-froms鈥 is endless, which is why it sold out after only two days 鈥 online and in-store 鈥 twice. Pro tip: Stock up before it does again.
