Costco Beauty Deals to Watch: Clean Beauty, Dupes & Viral Favorites
Costco isn’t just for bulk snacks and household staples anymore — it’s quietly becoming a beauty lover’s treasure trove. As beauty trends evolve toward cleaner ingredients, sustainable packaging and social‑media‑driven “dupes,” savvy shoppers are looking for ways to stock up on cult‑favorite products without draining their wallets. In this week’s Costco Beauty Deals breakdown, we explore four of the biggest beauty trends of 2025 and show how Costco’s product selection and pricing stack up. Get ready for a mix of dermatologist‑backed advice and insider deal alerts so you can glow up while keeping more money in your bank account.
Clean beauty & sustainable packaging
Interest in clean formulas continues to climb. An Exploding Topics report notes that more than 65 % of consumers are looking for environmentally friendly brands, and over half will pay more for sustainable products. At the same time, nearly a third of beauty products are now labeled “clean.” Consumers also want sustainability to go beyond the ingredient list: a recent trend report points out that “biotech innovations” and “sustainable packaging” are top trends for 2025–26. That means refillable components, post‑consumer‑recycled plastics and carbon‑neutral shipping are no longer niche — they’re expected.
How Costco taps the clean‑beauty trend
Costco has responded by offering more bundles featuring clean ingredients and eco‑conscious packaging. Korean brands like TirTir and Round Lab recently hit warehouse shelves. The TirTir Ultimate Hydrating & Lifting set — a three‑pack containing ceramic cream, collagen‑lifting eye cream and a bonus mini size — sells for $32.99 at Costco, while the individual items cost $49 if purchased separately at Ulta. Round Lab’s 1025 Dokdo Cleanser comes as a two‑bottle bundle with a travel size for $24.99, versus $15 for a single bottle at other retailers. Both brands emphasize microbiome‑friendly formulas and minimalist ingredient lists, making them ideal for shoppers seeking gentle, clean options.
Beauty dupes: affordable alternatives to luxury brands
The cost‑of‑living squeeze has accelerated the popularity of dupes — lower‑priced products that deliver results comparable to prestige formulas. A Cosmetics Business report found that 29 % of European shoppers have bought beauty dupes, and that figure jumps to 52 % for consumers aged 18–34. The same research notes that social media fuels dupe culture by flooding feeds with must‑have launches; budget‑conscious shoppers see dupes as a smart way to join the conversation without overspending.
Dupes you can score at Costco
Costco often bundles or discounts mass‑market products that perform like high‑end favorites. For example, L’Oréal Lumi Glotion — a luminous tinted moisturizer lauded on TikTok (over 30 million views) as a dupe for prestige glow primers — comes in a two‑pack for $15.99 at Costco. Similarly, Costco’s Maybelline Lifter Gloss three‑packs offer plumping glosses formulated with hyaluronic acid for under $10, saving shoppers about $25 compared with buying individual tubes at Target. These deals let you test trending dupes without paying full price.
Winter skincare routines: hydrate and protect
As temperatures drop, dermatologists recommend tweaking your routine. Winter skin‑care should “include hydrating formulas to keep seasonal dryness to a minimum,” according to Allure. Cold weather brings lower humidity, indoor heaters and chilly winds that make skin feel drier and look duller. The solution? Swap out harsh cleansers, layer humectants and moisturizers, and never skip sunscreen.
Bulk buys to winter‑proof your skin
Warehouse pricing makes it easy to stock up on hydrating essentials. Costco frequently offers multi‑packs of gentle cleansers, rich body creams and barrier‑strengthening serums. Korean brands like MediHeal sell Collagen Ampoule Pads in a 100‑pad box plus a refill for $28.99, whereas a single box runs about $24 at Ulta. Layering these collagen‑rich pads under your moisturizer can help retain moisture and improve elasticity all season long. Consider pairing them with Costco’s deals on Ceramide‑rich moisturizers and SPF creams to lock in hydration and defend against winter UV rays.
TikTok viral products: trending finds at Costco
Social media platforms like TikTok drive beauty discoveries. Over the past month, feeds have been flooded with “microbiome‑first” routines featuring prebiotic cleansers, probiotic serums and barrier‑friendly oils. These products cater to the skin’s microbiome, a living ecosystem that thrives on balance; over‑exfoliation can lead to redness and breakouts.
Viral hits you can stock up on
Costco has capitalized on viral buzz by stocking brands that regularly trend on social media. Some standouts:
K‑beauty cleansers & serums. The ACWELL Licorice pH Balancing Serum is a popular compliment to the wildly successful ACWELL Licorice Toner and is known for its skin brightening and hyperpigmentation reducing qualities. It’s currently available at Costco Online in a 2-pack for just $33.99.
Collagen masks and pads. Viral favorites like MediHeal Collagen Ampoule Pads and MediCube Collagen Night Masks give skin a glass‑skin glow with probiotic and collagen ingredients. TikTok fans love that these products deliver spa‑like results at home.
Designer fragrances and luxe skincare. Costco’s fragrance aisle has become TikTok‑famous thanks to designer scents like Chloé Eau de Parfum; a 3.3‑ounce bottle is $60 at Costco, compared with $181 at Ulta. Creator Brianna Ancheta’s viral video shows high‑end names such as Maison Margiela, Lancôme and Gucci all priced around $60.
From clean formulations and sustainable packaging to viral K‑beauty cleansers and affordable dupes for luxury products, Costco continues to align its shelves with the biggest beauty trends of 2025. By paying attention to what’s resonating with consumers — like microbiome‑friendly skincare and sustainable packaging — the retailer offers members the chance to experiment with buzzy products at lower risk.
