Ingredients Side-by-side
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
6 Benefits
Niacinamide has emerged as an all-star ingredient due to its many benefits.
Pentylene glycol is typically used within a product to thicken it. It also adds a smooth, soft, and moisturizing feel to the product. It is naturally found in plants such as sugar beets.
Zinc PCA (or "zinc salt") differs slightly from zinc itself. PCA stands for pyrrolidone carboxylic acid. However, Zinc PCA comes from zinc.
Dimethyl Isosorbide is a solvent and helps deliver actives into your skin. It is created from sorbitol.
Tamarindus Indica Seed Gum is from the seeds of Tamarindus indica. It is more commonly known as tamarind.
Xanthan gum is used as a stabilizer and thickener within cosmetic products. It helps give products a sticky, thick feeling - preventing them from being too runny.
Isoceteth-20 comes from Isocetyl Alcohol. It is an emulsifier. Emulsifiers help stabilize a product. It does this by preventing certain ingredients from separating.
Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.
Chlorphenesin is a synthetic preservative. It helps protect a product against bacteria in order to extend shelf life. In most cases, Chlorphenesin is paired with other preservatives such as phenoxyethanol and caprylyl glycol.
Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.
Dimethicone is a silicone used for making products smooth and silky. It also has the added benefit of sealing in hydration. The amount of dimethicone found in beauty products is considered safe and non-comedogenic, meaning it won't clog pores.
Cyclopentasiloxane is a silicone used to improve texture and trap moisture. An easier name for this is D5.
Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.
Propylene Glycol is an odorless, colorless liquid. As a humectant, it helps skin retain moisture. It also aids in delivering active ingredients.
Cyclohexasiloxane is a type of silicone more commonly known as D6. It is an emollient and solvent.
Betaine is a common humectant (a substance that promotes retention of moisture). It's known to be gentle on the skin and can help balance hydration.
Camellia Sinensis Extract is from the oil in tea plant leaves. The leaves give us various types of tea: green, black, oolong, and white.
Algae Extract is derived from Algae. Algae is an informal term for a group of aquatic organisms that can photosynthesize. It is estimated there are at least 30,000 types of Algae.
Antioxidant Helps brighten skin
Tocopheryl Acetate is AKA Vitamin E. It is an antioxidant and protects your skin from free radicals. Free radicals damage the skin by breaking down collagen.
Sodium PCA is the sodium salt of pyroglutamic acid and is naturally occurring on human skin.
Proline is an amino-acid. It helps moisturize the skin and plays an important role in creating proteins.
Arginine is an amino acid that is important for human development. Your body uses is it to produce hair keratin and skin collagen.
Glycine is an amino acid that helps build proteins. It is already present in our skin as our bodies produce them naturally.
Lysine is an essential amino acid. Your body is unable to produce it naturally and we mainly get lysine from food sources.
Glutamic Acid is an amino acid that is found in all living organisms. Our bodies use this to help nerve cells in the brain communicate with other cells.
Serine is an amino acid naturally found in our body. Our bodies use amino acids to create protein.
Threonine is an amino-acid. It helps hydrate the skin and has antioxidant benefits.
Sorbitol is a sugar alcohol. It is a hydrating and moisturizing agent created from the reduction process of glucose.
Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
Hydrogenated Polyisobutene is a synthetic polymer. Polymers are compounds with high molecular weight. Hydrogenated Polyisobutene is an emollient and texture enhancer.
C13-14 Isoparaffin is created from petroleum-based mineral oils. It is an emollient and helps thicken a product.
Polyacrylamide is a synthetic polymer. It is used to stabilize products and bind ingredients. When hydrated, Polyacrylamide forms a soft gel.
Carbomer is a polymer of acrylic acid. Its main role is to create gel consistency within products.
Laureth-7 is created by the ethoxylation of lauryl alcohol using ethylene oxide. Lauryl alcohol is a fatty alcohol with hydrating properties.
Disodium EDTA plays a role in making products more stable by aiding other preservatives.
Benzophenone-4 is a water-soluble chemical sunscreen.
Triethanolamine is an emulsifier and pH adjuster. It is created using ethylene oxide and ammonia. This gives Triethanolamine a nitrogen core and a similar scent to ammonia.
Phenoxyethanol is a preservative that has germicide, antimicrobial, and aromatic properties. Studies show that phenoxyethanol can prevent microbial growth. By itself, it has a scent that is similar to that of a rose.
Paraben 2 Concerns
Methylparaben is a preservative and is a paraben. It is used to prevent the growth of fungus, mold, and other harmful bacteria. Parabens are chemicals used as preservatives in both cosmetics and food.
2 Concerns
DMDM Hydantoin has antimicrobial and antifungal properties. It is a preservative that works by slowly releasing formaldehyde over time.

Gotta give credit where credit is due
WOW… lot of people ganging up on this incredibly affordable/popular serum. I understand the criticisms, but personally I don’t believe the intensity is warranted. For so many people this was the start of their skincare journey; it certainly was mine! And because I had never used ingredients like niacinamide or zinc on my face before, of course I noticed an incredible improvement in regards to my acne and skin tone evenness. This is a good serum to start with. No, you don’t need 10% strength (2%-5% works well) and for some that 10% can be irritating. However most people can handle 10% just fine so it’s not something many need worry about. The formulation isn’t elegant and sometimes it gets frothy or pills when you try to rub this in— BUT this is $6! You can’t really beat The Ordinary’s prices, and for some people $6 is all they can afford to spend on skincare so this is a good affordable option.
If you already have effective products with niacinamide in your routine, you do not need to add this in because it won’t really do anything for you. But if you’re just washing your face with something like dish soap then of course this will make an incredible difference. You’ll probably move on from it eventually, but it’s an effective place to start. Wishing everyone the best on their skincare journey. <3

(Tried Jan 2021) This was actually the product that made me realize that my skin does not mix with Niacinamide (especially at high concentrations because I can usually tolerate it at %4/less or when it isn't a primary ingredient). I tested it on my wrist and a small patch on my cheek to check, and I had hives in both areas. I wouldn't want to give this a poor rating solely on the account of my allergic reaction as I'm sure it works for many others.
