Face serums explained: niacinamide, vitamin C, hyaluronic acid and dark spot serums

Serums are lightweight, leave-on products applied after cleansing. Here is what each of ours says on its product page, in plain language. These are cosmetic products and results vary.

Niacinamide

Our 10% Niacinamide Serum ($30) is a 1 fl oz serum that lists niacinamide with sodium hyaluronate, chamomile flower extract and allantoin. The page describes it as aimed at the look of uneven tone and pore appearance. To use it, take a pea-sized amount and tap it gently onto your face and neck.

The Vitamin Glow Serum ($30) also contains niacinamide, along with 3-O-ethyl ascorbic acid (vitamin C), vitamin E, panthenol and linoleic acid. The page describes it as supporting a healthy-looking glow and a more even-looking tone. Apply 3-4 drops after cleansing.

Vitamin C

The Vitamin C Serum ($25) lists L-ascorbic acid, magnesium ascorbyl phosphate, 3-glyceryl ascorbate and ferulic acid, plus botanical extracts. It is described as promoting a brighter-looking complexion. Apply a small amount to clean, dry skin, and avoid sun exposure after application.

Hyaluronic acid

The EvenWell Hyaluronic Acid Serum ($25) lists four forms of hyaluronic acid with glycerin and propanediol in a water-based formula. The page describes it as supporting hydration. It is a cosmetic product and makes no claim to change skin permanently.

Dark spot serums

The EvenWell Dark Spot Serum ($25) lists niacinamide, kojic acid, azelaic acid and hexylresorcinol with botanical extracts and glycerin. It is described as supporting a brighter, more even-looking complexion. The page notes that results vary and that it does not promise to remove pigmentation permanently. It also recommends broad-spectrum sunscreen during the day.

The EvenWell Dark Spot Serum for Sensitive Skin ($35) does not contain kojic acid. It relies on mushroom and other plant extracts instead, and is described as supporting an even-looking tone.

Using serums sensibly

Every ingredient is listed on each product page. Patch-test a new serum first, add one new product at a time, and stop if irritation occurs. All are for external use only; avoid your eyes. Not sure what to pick? Take the 60-second quiz or see our bundles.

Frequently asked questions

Do I need sunscreen with these?

Will a serum give me guaranteed results?

No. These are cosmetic products and results vary.

Can I use more than one serum?

Add one at a time so you can tell how your skin responds, and follow each product label.
