The Abnormal Evaluation: A Evaluation of The 10 Greatest The Abnormal Skincare Merchandise

The Ordinary is a popular skincare brand under the global beauty brand, Deciem’s, umbrella. The brand’s founding philosophy is “clinical formulations with integrity”. For them, this means skincare treatments that provide solutions to real needs while maintaining open communication and honesty at all stages of their operations.

Each of The Ordinary skincare formulations is simple, containing only a few ingredients including one or two actives, and leaving out additives, fillers, fragrance, and dyes. Even the product packaging is minimal with straightforward names that describe exactly what the product is without any extra fluff or deceptive details. This approach to skincare has enabled The Ordinary to become one of the most popular (and affordable) skincare brands on the market today. In fact, none of the brand’s products cost more than $15. 

Even though The Ordinary skincare products are popular, it’s still necessary to evaluate the product formulations to determine what key ingredients are used and whether or not there’s research to support the use of these ingredients in skincare products.

What is The Best The Ordinary Serum?

The Ordinary serum collection is pretty extensive, which may leave you wondering which one is the best. While the serum you choose will depend on your skin concerns, we think The Ordinary Buffet is one of the brand’s best serums. With a combination of peptides, probiotics, amino acids, and multiple hyaluronic acid complexes, The Ordinary Buffet should help to reduce multiple signs of aging while also improving your skin’s hydration. 

What Are The Key Ingredients in The Ordinary Skincare Products?

After reading about the best selling The Ordinary skincare products, you may be wondering what exactly ingredients like peptides, retinol, squalane, and salicylic acid can do for your skin. Below we’ll give you a brief description of each of the key ingredients used in the best selling products by The Ordinary. 


Alpha Hydroxy Acids (AHAs)

AHAs are the key ingredients in The Ordinary Peeling Solution, but you’ll also find AHAs in several other The Ordinary skincare products. The primary benefit of AHAs is their ability to exfoliate the skin by targeting corneocytes (dead skin cells that make up the stratum corneum) in a process called corneocyte desquamation. By enhancing their breakdown and increasing the separation of skin cells, the rate of cell turnover is increased, leading to smoother, brighter skin and a more even complexion. According to a publication in the journal Molecules, AHAs can be used to easily peel all types of skin with minimal risk.


Salicylic Acid

The Ordinary Salicylic Acid Masque and The Ordinary Peeling Solution use salicylic acid, 

a type of beta hydroxy acid (BHA), to soften and dissolve keratin. Keratin is a protein found in the skin that acts as a “glue” to keep cells together. This allows salicylic acid to exfoliate the skin and slough off dead skin cells. Salicylic acid also has the ability to penetrate deep into pores, where it helps to loosen clogs and allows oil to flow out more freely. Thus, salicylic acid is known to break down blackheads and whiteheads.



Several of The Ordinary skincare products include multiple peptide technologies, one being the Matrixyl 3000 complex. Matrixyl 3000 is a combination of the matrikines palmitoyl tripeptide-1 and palmitoyl tetrapeptide-7 that provide anti-aging benefits by signaling to cells to produce more collagen.

Another technology in The Ordinary Buffet is the Matrixyl synthe’6 peptide complex with palmitoyl tripeptide-38, a peptide derived from the tripeptide KMK naturally found in collagen VI and laminin. In-vitro studies have found palmitoyl tripeptide-38 to have a matrikine-like effect that stimulates the synthesis of collagen I, II, IV, fibronectin, hyaluronic acid, and laminin 5.

The Ordinary Buffet also contains a unique peptide complex called SYN-AKE, a synthetic peptide that mimics the effects of the peptide Waglerin 1. Waglerin 1 is a component of the venom found in the Temple Viper, a poisonous snake native to southeast Asia. SYN-AKE peptide complex works by reducing muscular contractions in the face and reduces cell movement; thereby keeping the skin smooth.

The relistase peptide complex in The Ordinary Buffet is designed to increase skin firmness and improve the appearance of fine lines and wrinkles by inhibiting the enzyme elastase.

The final peptide complex in The Ordinary Buffet is ARGIRELOX peptide complex (with acetyl hexapeptide-8, pentapeptide-18). ARGIRELOX fights expression wrinkles by attenuating muscle contraction in the pre-synaptic pathway.



The Ordinary retinol products are ideal for those with signs of aging and/or acne prone skin. According to a publication in the journal Clinical Interventions in Aging,

retinol can minimize the appearance of fine lines and wrinkles, improve uneven skin tone, restore skin firmness, and shrink the appearance of enlarged pores. After application, retinol is converted to retinoic acid, which works deep within the skin where it boosts collagen synthesis, increases elasticity, and repairs connective tissue. It also increases cellular turnover, which helps to prevent clogged pores and promotes smoother, healthier skin. 



Many of The Ordinary skincare products include squalane because it is a very effective emollient. Squalane is a saturated and stable hydrocarbon that mimics squalene (note the e), a natural compound in your skin that plays an important role in lubrication and protection. Squalane helps to replenish and strengthen the skin’s lipid barrier. The Ordinary Squalane is a facial oil with 100% pure squalane, but you’ll also find this ingredient in several other products, such as The Ordinary Squalane Cleanser and The Ordinary retinol products. 



The Ordinary Niacinamide + Zinc is a great option for all skin types due to its high concentration of niacinamide, the amide form of vitamin B3 (niacin) that provides many benefits to the skin. For instance, a publication in theJournal of Clinical and Aesthetic Dermatology, states that niacinamide can repair the skin barrier and improve skin moisture, as well as reduce inflammation, blotchiness, hyperpigmentation, acne, and wrinkling.

You may want to consider The Ordinary Niacinamide + Zinc if you have acne-prone skin since niacinamide has antimicrobial and sebostatic effects, meaning it can help protect against the bacteria that cause acne while also helping to reduce oil production. Two double-blind studies published in the International Journal of Dermatology (one in 1995, the other in 2013) found that a topical preparation of 4% niacinamide treated moderate acne just as well as 1% clindamycin (a topical antibiotic prescribed for acne) when applied twice daily for eight weeks. And a study published in the Journal of Cosmetic and Laser Therapy found that a 2% topical niacinamide formulation could reduce oil production.

Where are The Ordinary Skincare Products Sold?

The Ordinary skincare products are sold on the brand’s website, as well as third party sellers like Amazon, Ulta, and Sephora. The brand has a store locator and list of authorized retailers on their website. 

What is The Ordinary Return Policy?

Is The Ordinary Cruelty Free?

The Ordinary is cruelty free. DECIEM and The Ordinary do not test on animals and do not ask others to do so. For this reason, none of their brands or products are sold in stores or conventional retailers in mainland China, since such sales require animal testing for registration purposes.

The Ordinary reviews on the brand’s website are overall very positive. We noticed that many of The Ordinary reviews focus on the brand’s effective formulations and affordability. It is common to find customers comparing The Ordinary skincare products to some of the most well known and respected skincare brands as comparable and more affordable.

Other The Ordinary reviews appreciate the detail the brand takes in explaining their products, ingredients, and the science behind why they work well for the skin. This helps customers feel informed about their skincare purchases and further exemplifies The Ordinary’s mission to provide clinical skincare solutions with integrity.

Negative The Ordinary reviews are mostly from customers who experienced reactions to these products, such as skin irritation and breakouts. To prevent this from happening, the brand recommends following The Ordinary Patch Test Guide. Patch tests are an easy way to help predict if you will have a negative initial reaction to a new product. It is recommended to perform a patch test before incorporating a new product into your routine.

Our Verdict

Since its debut, The Ordinary has received glowing reviews. The products work, and experts in the skincare industry respect the brand not only for the quality of their product but for the company’s transparency. They take the time to explain the ingredients and science behind each formulation. Overall, we think that The Ordinary products are formulated well with high-quality, evidence based ingredients. And it’s a plus that the products are priced low, making this brand accessible to many consumers.

What Are Some Alternatives to The Ordinary Skincare?

One thing that we noticed about The Ordinary is that all of their exfoliating products use chemical exfoliants, like AHAs and BHA. But keep in mind that as we age, our skin’s natural shedding process slows down. Excess dead cells build up on the outermost layer of the skin, resulting in a rough, dull complexion. All of this is to say you may need more than just chemical exfoliants to achieve deep exfoliation. That’s why we’d like to recommend Formulyst’s Retexturizing Microdermabrasion Exfoliator. 

The Retexturizing Microdermabrasion Exfoliator is formulated to gently exfoliate built-up layers of dead skin to expose the younger, more vibrant-looking skin beneath. The formula contains fine aluminum oxide crystals to effectively remove dirt, excess oil, and dead cells, while nutrient-rich jojoba oil, red tea extract, apricot kernel oil, squalane, and hyaluronic acid deeply nourish and soothe newly exposed skin. Also, by removing the dead surface skin cells, products can penetrate deeper and make-up goes on smoother, enhancing the efficacy of your overall skincare routine. Overall, Formulyst Retexturizing Microdermabrasion Exfoliator can help reveal smoother skin with less visible lines and wrinkles.

There’s no need to compromise when it comes to finding skincare that is effective and safe. Carrot & Stick takes a tough love approach to skincare, perfectly balancing the power of plants with cutting edge science. Not only is Carrot & Stick good for your skin, it is also good for the environment as the formulas skip harmful chemicals as well as the preservatives, emulsifiers and thickeners commonly found in skincare products.
