ONE/SIZE Beauty, founded by beauty creator Patrick Starrr, has developed a strong identity around high-performance makeup, bold self-expression, and products designed for a wide range of skin tones and makeup styles. Rather than trying to compete solely as another celebrity beauty brand, ONE/SIZE has built much of its reputation around complexion products, setting products, primers, powders, color cosmetics, and especially long-wear makeup.

After reviewing the brand’s official product information, customer feedback on Trustpilot and Sephora, Reddit discussions, and independent beauty commentary, my overall impression is that ONE/SIZE is a legitimate beauty brand with several genuinely impressive products, but the experience isn’t equally strong across every product or every customer-service interaction.

The brand’s strongest reputation is around makeup longevity, oil control, setting products, and full-glam performance. Its On ‘Til Dawn Mattifying Waterproof Setting Spray has developed a particularly loyal following among people with oily skin and those who need makeup to survive long days, heat, sweat, or events. At the same time, recent customer feedback reveals concerns around shipping, customer service, packaging and occasional product-performance issues.

If you’re considering an order, I recommend checking the latest ONE/SIZE Beauty coupons and deals before checkout, especially because the brand regularly runs promotions and offers.

What Is ONE/SIZE Beauty?

ONE/SIZE Beauty was founded by Patrick Starrr, a prominent beauty creator and makeup personality. The brand describes itself as a beauty company created for “every brand of beauty,” with an emphasis on performance, innovation, inclusion and self-expression.

According to ONE/SIZE’s official About page, Patrick Starrr is a licensed esthetician and developed the brand around the idea that makeup should perform across different skin types, skin tones, ages and genders. The brand also says its products are intentionally formulated for everyone and describes its formulas as clinically validated.

The current ONE/SIZE range includes:

• Primers
• Setting sprays
• Setting powders
• Color correctors
• Blushes
• Foundation and concealer products
• Lip products
• Eyeliners and mascara
• Moisturizer and skin-prep products
• Makeup tools and sponges

The official collection currently highlights categories such as Setting Spray + Powder, Primer, Color Corrector, Blush, Moisturizer, Foundation + Concealer, LIP, Eyeliner + Mascara, and Tools.

My Expert Assessment of ONE/SIZE Beauty

From a makeup-editorial perspective, ONE/SIZE is most interesting when you look at what the brand is actually trying to solve.

This isn’t primarily a minimalist “barely there” makeup brand. Even though ONE/SIZE offers products that can be incorporated into simpler routines, its strongest identity is performance-oriented makeup. The brand clearly appeals to people who want their complexion to look polished and stay in place.

That positioning is particularly apparent with its setting products. The brand’s On ‘Til Dawn Mattifying Waterproof Setting Spray is designed around long wear, matte finish and resistance to sweat and water. Customer discussions repeatedly come back to those exact benefits.

For oily or combination skin, that can be a major advantage. For very dry or dehydrated skin, however, the same level of mattifying performance can potentially feel too aggressive. Recent Sephora reviews illustrate this split: one verified buyer praised the spray for keeping makeup from moving, while another found the finish excessively matte and uncomfortable.

That difference in experience is important. ONE/SIZE isn’t necessarily a brand where one product will suit everyone simply because the brand name emphasizes “ONE/SIZE fits all.” Skin type, climate, makeup style and desired finish still matter.

On ‘Til Dawn Setting Spray: The Brand’s Standout

If I had to identify the product category that best represents ONE/SIZE’s reputation, it would be setting spray.

The On ‘Til Dawn Mattifying Waterproof Setting Spray currently has more than 2,600 customer reviews on Sephora’s international product listing and an overall rating of about 4.0/5. The review distribution shows a substantial majority of 5-star ratings, but also a meaningful number of 1-star reviews, which reflects the product’s polarizing nature.

Positive customers frequently describe the spray as extremely effective for extending makeup wear. Some Reddit users have also described it as one of their preferred setting sprays for long wear and oily skin.

One Reddit discussion comparing setting sprays included multiple users specifically preferring ONE/SIZE over Charlotte Tilbury because they felt it controlled oil better and extended makeup wear for many hours. One user described it as a product they repurchase and keep backups of.

There is another side, though. Reddit users have reported issues such as the spray separating, difficulty getting the product out of the bottle, or makeup performance not matching expectations in hot conditions.

Recent Sephora reviews also mention faulty spray mechanisms and inconsistent distribution. One verified buyer reported that the first several sprays repeatedly delivered little or none of the formula, while another complained that the product gave an oily appearance and that the spray mechanism stopped working.

My verdict on the setting spray: the formula appears to have a genuinely strong reputation for longevity, particularly among oily-skin and full-glam users, but the packaging/dispenser experience deserves consideration.

Is ONE/SIZE Good for Oily Skin?

This is probably the brand’s strongest target audience.

ONE/SIZE has built multiple products around controlling shine and extending makeup wear. The combination of primer, setting powder and long-wear setting spray makes it possible to create a routine specifically designed for people whose makeup tends to break down during the day.

Reddit discussions reinforce this reputation. In a BeautyGuruChatter discussion, a user with oily skin and hyperpigmentation said they particularly liked several ONE/SIZE products, including the contour/bronzer palette, concealer and setting spray. The same user described the setting spray as a staple and praised its ability to keep makeup in place.

Another Reddit user specifically asked about ONE/SIZE products for very oily skin and high-sweat conditions, mentioning the brand’s Secure the Blur and Secure the Sweat + Oil Sucker primers.

That doesn’t prove the products will work for everyone with oily skin, but it does demonstrate that oil control is one of the brand’s strongest areas of consumer interest.

ONE/SIZE Primers

ONE/SIZE offers several primer options intended for different makeup-preparation needs. Among the better-known products are Secure the Blur and Secure the Sweat.

Secure the Blur is positioned toward creating a smoother-looking base, while Secure the Sweat focuses more directly on makeup longevity and resistance to sweat.

These products are particularly relevant if your makeup tends to separate around the nose, forehead or other areas that become oily during the day.

However, primer compatibility is highly dependent on the foundation you use afterward. A silicone-heavy primer, water-based foundation, skincare-heavy base or very emollient complexion product can behave differently depending on how the formulas interact.

That is why I would avoid buying an entire ONE/SIZE base routine simply because the products are designed to work together. If you already have a foundation that you love, introduce one ONE/SIZE primer at a time.

ONE/SIZE Setting Powder

The brand’s setting powders are another important part of its performance-focused approach.

ONE/SIZE powders are designed to blur, set and help control shine without requiring a heavy-looking layer of traditional powder. Customer discussions frequently mention the brand’s powder alongside its setting spray.

A recent Trustpilot reviewer specifically described the brand’s airbrush powder as their favorite ONE/SIZE product and praised the makeup generally for its quality and reasonable pricing.

The key consideration here is skin type. A powder that looks beautifully smooth on oily skin can appear too dry on dehydrated skin. If your complexion naturally lacks moisture, a lighter application around the cheeks and heavier setting only in the T-zone is likely to be more appropriate than applying a large amount everywhere.

ONE/SIZE Concealer and Complexion Products

ONE/SIZE also offers foundation and concealer products designed to support fuller, polished makeup looks.

Reddit feedback about the concealer has been positive in some communities. One long-term beauty discussion described the ONE/SIZE concealer as providing a full-coverage satin finish and compared its appearance favorably with another popular full-coverage foundation/concealer product.

That type of feedback is consistent with the overall brand philosophy: ONE/SIZE generally seems more interested in performance and visible complexion enhancement than in creating barely detectable makeup.

If you prefer lightweight skin tints and very natural coverage, some ONE/SIZE complexion products may therefore feel more substantial than what you normally reach for.

ONE/SIZE Color Products

The brand has expanded beyond its original performance-focused complexion identity and now offers blush, lip, eye and other color products.

One of the earlier products that received attention from beauty enthusiasts was the Visionary Palette. A Reddit review of the palette described a 15-shade format containing nine mattes and six shimmers, with the reviewer also discussing the packaging, mirror and pan layout.

While that palette represents an earlier stage of the brand, it demonstrates something that has remained consistent: ONE/SIZE isn’t afraid of expressive makeup.

The brand is particularly attractive to consumers who enjoy creating a polished full-face look rather than limiting themselves to minimal makeup.

What Customers Say on Trustpilot

Trustpilot gives a very different picture from product-specific retailer reviews because it captures the broader shopping and customer-service experience.

The current Trustpilot profile contains a mixture of very positive and very negative customer experiences. Positive reviews praise the makeup’s quality, particularly powders, and some customers say they are surprised by the negative feedback because their own shopping experience was good.

However, recent negative reviews repeatedly mention customer-service and fulfillment issues.

One customer reported that an order remained unfulfilled and that the tracking number showed only “label created.” The customer also described receiving automated responses that did not address the problem and frustration while attempting to obtain a refund.

Another 2026 reviewer complained about an order that could not be modified even though they contacted customer service within hours of placing it. The reviewer also alleged that international returns were not accepted in their situation.

There are also positive Trustpilot experiences. One April 2026 reviewer said they liked the brand, described the makeup as good quality and reasonably priced, and singled out the airbrush powder as particularly impressive.

This creates an important distinction: the product reputation appears stronger than the direct-to-consumer customer-service reputation.

Shipping and Customer Service

This is the area where I would exercise the most caution when buying directly from ONE/SIZE’s website.

The brand’s official FAQ says U.S. orders qualify for free standard shipping at $50, with different thresholds for Canada, the UK and Europe. The same FAQ states that U.S. customers can return or exchange qualifying items within 30 days of receipt, provided products are unopened or gently used.

That policy is reasonable on paper.

The problem is that several recent Trustpilot reviews describe difficulties with fulfillment, delivery, order changes and customer-service responses. These are individual customer reports rather than proof that every order will have problems, but the pattern is worth noting.

If you’re ordering directly from the brand, I recommend keeping your order confirmation and tracking information until everything arrives. If you’re in a hurry for a specific event, purchasing from a major retailer with a predictable local fulfillment network may be worth considering.

ONE/SIZE Returns

The official ONE/SIZE FAQ currently states that U.S. customers can receive free returns and/or exchanges within 30 days of receiving eligible products purchased from onesizebeauty.com. Returned merchandise must be unopened or gently used. Products bought through retail partners need to be returned to the retailer where they were purchased.

International customers should pay particular attention to the applicable terms because Trustpilot contains at least one recent complaint involving an international order and returns.

My advice is to check the return policy for your specific country before ordering rather than assuming that the U.S. policy applies internationally.

What Reddit Users Think About ONE/SIZE

Reddit is particularly useful for ONE/SIZE because makeup enthusiasts often discuss the brand in the context of specific skin types and makeup routines.

The overall sentiment I found is mixed-to-positive at the product level.

Some users describe the setting spray as a holy-grail-type product, particularly for oily skin and long-wear makeup. Others have complained that it can feel harsh, overly matte, smell strong, separate, or fail to perform under certain conditions.

There are also users who like multiple ONE/SIZE products. A BeautyGuruChatter discussion includes a user who praised the brand’s brow gel, contour/bronzer palette, concealer and setting spray.

Importantly, Reddit doesn’t show a universal consensus that the brand is either amazing or terrible. Instead, the strongest pattern is that product selection matters. Someone with oily skin who needs 12-hour makeup may love a product that someone with dry skin finds uncomfortable.

What About Quora and Facebook?

I also looked for useful independent discussions about ONE/SIZE on Quora and Facebook. The publicly accessible material I could verify was considerably less substantial than the Reddit, Trustpilot and retailer-review evidence.

Because of that, I wouldn’t manufacture a Quora or Facebook “consensus.” In my view, the strongest evidence currently comes from product-level customer reviews and beauty-community discussions, while Trustpilot is more useful for evaluating the brand’s direct customer-service experience.

Is ONE/SIZE Cruelty-Free?

ONE/SIZE products are listed as cruelty-free on retailer product information. For example, Sephora’s listing for the Turn Up The Base Infinity Beauty Sponge identifies the product as cruelty-free.

If cruelty-free status is an important purchasing criterion for you, I recommend checking the current product page and the brand’s current policy before purchasing because cosmetic-company policies can change over time.

Who Is ONE/SIZE Best For?

In my assessment, ONE/SIZE is particularly well suited to people who:

• Have oily or combination skin.
• Need makeup to last through long days.
• Prefer matte or soft-matte finishes.
• Enjoy full-glam or polished makeup.
• Want strong setting and oil-control performance.
• Like experimenting with bold makeup looks.
• Prefer makeup with a strong performance-oriented identity.

Who May Not Love ONE/SIZE?

You may want to be more selective if you:

• Have very dry or dehydrated skin.
• Prefer naturally dewy makeup.
• Dislike strong fragrance or alcohol-heavy-feeling setting products.
• Prefer very lightweight makeup.
• Need highly responsive customer service for urgent orders.
• Are ordering internationally and want an especially simple return process.

Pros of ONE/SIZE Beauty

• Excellent reputation for longevity: Particularly with setting products.
• Strong for oily skin: Multiple products focus on shine and makeup breakdown.
• Good product variety: The range now extends from complexion to lips, eyes, blush, skincare and tools.
• Inclusive brand positioning: The company explicitly develops products for different skin tones, types, ages and genders.
• Strong community following: Several products have developed loyal repeat customers.
• Good retailer presence: Products are available through established beauty retailers, making them easier to test or purchase without relying exclusively on the brand’s own fulfillment.
• Free U.S. shipping threshold: The official site currently offers free standard U.S. shipping on qualifying $50+ orders.

Cons of ONE/SIZE Beauty

• Direct-order customer-service complaints: Recent Trustpilot reviews include multiple complaints about support and fulfillment.
• Some products are polarizing: Particularly the very matte setting products.
• Packaging/dispenser complaints: Some users report problems with the setting-spray mechanism.
• Can be too matte for dry skin: The brand’s strongest performance characteristics can become disadvantages for some skin types.
• International policies can differ: Customers outside the U.S. should carefully check return and shipping terms.
• Not every product has the same reputation: The strongest customer enthusiasm tends to concentrate around certain products rather than the entire catalog.

Is ONE/SIZE Beauty Legit?

Yes, ONE/SIZE Beauty is a legitimate beauty brand.

It was founded by established beauty creator Patrick Starrr, has an active official website, sells through major beauty retailers, and has a substantial volume of customer feedback across platforms such as Sephora, Trustpilot and Reddit.

The real question isn’t whether ONE/SIZE is legitimate. It is whether the specific product you want matches your skin type, desired finish and makeup routine.

Is ONE/SIZE Beauty Worth It?

For the right customer, yes.

I wouldn’t recommend buying the entire range simply because ONE/SIZE has a strong reputation. Instead, I would start with the product category that best matches your needs.

If your biggest problem is makeup disappearing during the day, the setting products are the obvious place to investigate. If you have oily skin, the brand’s primers and powders are also worth considering. If you prefer a fresh, dewy and barely-there complexion, I’d be more selective because some of the brand’s best-known products are intentionally designed to create a much more controlled matte finish.

The product-level customer feedback is considerably more encouraging than the direct customer-service complaints found on Trustpilot. That distinction is important when deciding where to buy.

My Final Verdict

Overall rating: 4.2/5

ONE/SIZE Beauty has successfully moved beyond being simply “Patrick Starrr’s makeup brand.” Its strongest products have earned genuine loyalty from beauty consumers, particularly people who want their makeup to stay put for long periods.

The On ‘Til Dawn Setting Spray is the clearest example. Its large volume of customer reviews and enthusiastic Reddit discussions demonstrate why it has become associated with long-lasting, oil-controlling makeup. At the same time, recent customer feedback shows that the product isn’t universally loved, particularly by people who dislike extremely matte finishes or have experienced problems with the spray mechanism.

The bigger concern is the direct-to-consumer shopping experience. Recent Trustpilot reviews contain enough complaints about fulfillment and customer service that I would consider buying through an established retailer when the price is similar and the retailer offers an easier return process.

Overall, ONE/SIZE is worth considering, especially if you have oily skin or prioritize long-wearing makeup. Just choose products according to your skin type rather than assuming the entire range will work equally well for you.

Before placing an order, it’s also worth checking the latest ONE/SIZE Beauty coupon codes and deals so you can potentially reduce the cost of your purchase.
