The right ingredients can help to target specific skin concerns. Neutrogena® is here to help you understand the benefits of key skincare ingredients like AHAs, PHAs, Salicylic Acid, Retinol, Peptides, Benzoyl Peroxide, Vitamin C and more. Explore all the skincare ingredients Neutrogena has to offer and their skin benefits.

Hyaluronic acid

Hyaluronic acid is a compound that occurs naturally in the skin and helps it hold onto water. And when water is retained in the skin, your complexion appears plumper, smoother and more radiant. 1 The problem is, as the skin matures, it doesn’t hold onto water as effectively, meaning that moisture is more easily lost. – which is why adding moisture back into the skin via a topical hyaluronic acid, such as Neutrogena® Hydro Boost, is so important.

Salicylic acid

Salicylic acid is one of the most common beta-hydroxy acids (BHAs) that occurs as a natural compound in plants. Because of its anti-inflammatory and anti-bacterial nature, salicylic acid is used within skincare to promote exfoliation (keratolytic agent), and to remove bacteria, particles, and sebum. 2 Salicylic acid works by softening the top layer of the skin (epidermis) to remove dead skin cells and debris. Neutrogena provides a variety of products that contain salicylic acid for targeting common skin concerns such as acne and blackheads, or simply as a day-to-day skincare for keeping your complexion clear.

Vitamin C

Vitamin C is the most abundant antioxidant in our skin and co-exists to protect our skin from free-radicals. Products with Vitamin C offer reparative properties and can help treat an array of skincare concerns, such as dark spots and anti-aging. Vitamin C is among the most beneficial ingredients in the skincare industry, and is used to combat signs of aging, wrinkles, dark spots, improve water retention, and much more. Neutrogena® is proud to offer multiple skincare products that contain Vitamin C.


Retinol is a type of over-the-counter topical retinoid, which is a derivative of Vitamin A. Retinol has become one of the primary ingredients used by skincare companies today, especially as an anti-aging skincare ingredient. 3 Retinol complements the skin’s natural surface renewal, revealing radiant-looking, new skin while sloughing off dead skin cells to help diminish the signs of aging. Neutrogena® offers a line of retinol skincare products that can help you defy visible effects of aging to look and feel your best.


An AHA is an alpha hydroxy acid, such as glycolic acid. The chemical exfoliation factors in AHAs can help remove dead skin cells to complement skin’s natural turnover process for a smoother complexion.4 Polyhydroxy acids, or PHAs, are acid compounds that tackle the look of fine lines and wrinkles and have similar effects as AHAs.5,6

There are multiple benefits of relying on AHAs and PHAs as part of your skincare regimen such as exfoliating the skin, unclogging pores, reducing the look of surface lines and wrinkles and more.


Peptides are chains of amino acids. They form the building blocks of essential proteins, such as collagen and elastin, that keep skin soft, bouncy, and healthy-looking. 7 Peptides in skincare products can be absorbed within the skin's surface and provide targeted benefits for a multitude of skincare concerns such as increasing skin firmness, improving skin texture, and reducing the appearance of fine lines and wrinkles. Neutrogena® products that contain peptides are scientifically proven to help firm and contour skin and target visible effects of collagen and elastin depleted skin.

Benzoyl Peroxide

Benzoyl peroxide is an antiseptic topical ingredient that kills bacteria that cause mild-to-moderate acne, making it a key ingredient in many acne-fighting products.

Benzoyl Peroxide can be an effective addition to a regimen, with several acne-fighting benefits such as drying and helping clear up acne pimples, reducing the number or severity of acne pimples, helping skin stay clear and prevents new pimples and more.9 Neutrogena® offers many acne-fighting products with benzoyl peroxide.
