Brand Overview

The Inkey List’s Collagen Booster Face Serum is a great way for all skin types to see how peptides work to repair and, to some extent, improve collagen production. Assuming your daily skin care routine already includes broad-spectrum sun protection, you should see fewer fine lines and wrinkles from using this serum.

Like many products form The Inkey List, Collagen Booster Face Serum is packaged in an opaque, short bottle topped with a dispensing cap. This type of packaging works well to keep the fatty acid portion of the peptide ingredients stable during use--an important consideration in order to ensure the peptides remain effective during use.

The serum’s super-light, non-sticky liquid-gel texture glides over skin, and layers well with other products.

Along with peptides known to signal skin to make better collagen, skin also gets the salt form of hyaluronic acid, known as sodium hyaluronate. This ingredient plus the trifecta of glycerin, propanediol, and butylene glycol are what give this fragrance-free serum its pleasant slip and hydrating abilities.

All that’s missing are antioxidants and a better mix of replenishing ingredients to strengthen and reinforce skin’s barrier; however, at this product’s price, something had to be left out! As is, you’re getting a fairly impressive serum that can be combined with one of our top-rated serums for enhanced results.

The Inkey List is the creation of Colette Newberry and Mark Curry, respectively the former branding and product developers of the widespread UK-based drugstore chain Boots, which has its own namesake skin care line. As with a number of up-and-coming “indie” brands, the media coverage centers on their inexpensive products with minimalist formulas that tend to focus on a single star ingredient, such as hyaluronic acid, squalane, or retinol.

If you’re wondering about the inspiration for the name, it’s the pronunciation of the acronym “INCI,” which stands for the International Nomenclature of Cosmetic Ingredients, an agreed-upon, regulated list of how cosmetics ingredients should be identified on product labels. Each product has its chief ingredient listed on the packaging with dictionary-style writing underneath showing how the name is phoneticized, a clever and slightly erudite touch.

Though the formulas are somewhat basic, The Inkey List gets its packaging spot-on – all products are in opaque containers, with no jars or clear containers to be found. Fragrance isn’t on this brand’s radar, either--at least not in terms of adding it to their products (which will make your skin very happy).

We’d like to see more complex formulas, but then again such formulas cost more to make, and The Inkey List is mostly a bargain brand. We wrote “mostly” because in some cases, on an ounce-per-ounce basis, The Inkey List costs just as much as some other brands offering the same type of products (like leave-on exfoliants) in larger sizes.

Even with the predominantly one-note ingredient theme, the brand typically includes beneficial ingredients in efficacious amounts and skips irritants, with the exception of a couple a products that contain witch hazel water and drying denatured alcohol.

That aside, the brand offers a good selection of effective products, something we’re always glad to see. The Inkey List is sold exclusively in the U.S. at Sephora; you can learn more about the brand here:
