What is Hexylresorcinol: Neutrogena skincare ingredient glossary

Hexylresorcinol is a versatile synthetic compound celebrated for its ability to combat hyperpigmentation and enhance overall skin tone, boasting skin-brightening and anti-aging benefits. It's a peach-colored powder or sticky yellow liquid that solidifies at room temperature. A derivative of resorcinol, a known antiseptic, hexylresorcinol packs a skin-solving punch with antimicrobial properties, making it an excellent choice for skincare formulas.

Numerous studies highlight hexylresorcinol's impressive antioxidant capabilities, too. By neutralizing harmful environmental aggressors — we're looking at you, pollution and smog — this ingredient helps maintain youthful, radiant skin.

But it doesn't stop there. Hexylresorcinol also stimulates the production of skin-saving molecules like glutathione, which helps further safeguard the skin from oxidative damage. Hexylresorcinol's safety and effectiveness in over-the-counter products make it a trusted ingredient in the skincare industry.

You probably won't overhear friends talking about hexylresorcinol when sharing their secrets to even, youthful-looking skin (or at least not yet!). But while it isn't exactly a skincare buzzword, this superstar ingredient has a few impressive uses for skin.

Reduces dark spots

Hexylresorcinol can help lighten dark spots when applied topically to the skin. One study showed that 1% hexylresorcinol was well tolerated and provided equivalent results to 2% hydroquinone — a commonly sought-after skin-lightening ingredient — in reducing the appearance of pigmentation on the face and hands.

Brightens skin

In addition to lightening dark spots for a more even complexion, hexylresorcinol is clinically proven to enhance skin brightness. Research showed that participants who used a topical facial formula including vitamin C, vitamin E and hexylresorcinol saw a 45% improvement in skin brightness.

Supports collagen production

This ingredient has also been shown to improve collagen and elastin synthesis, two key proteins responsible for firm, youthful-looking skin.

Minimizes signs of skin aging

If crow's feet, wrinkles and skin laxity have you feeling down, hexylresorcinol can help. Thanks to its antioxidant and anti-inflammatory properties, research published in the Journal of Cosmetic Dermatology showed this ingredient can help mitigate ultraviolet (UV)-induced photoaging, or sun damage that accelerates skin aging.

Meanwhile, the International Journal of Cosmetic Science reported that a combination of hexylresorcinol and niacinamide markedly improved crow's feet, fine lines and wrinkles.

Discovered in 1925 by Baltimore chemist Dr. Veader Leonard, hexylresorcinol is a chemically modified derivative of resorcinol, an organic phenolic compound. Historically, people used hexylresorcinol in the medical field as an antiseptic and anesthetic before it caught dermatologists' and skincare enthusiasts' attention.

Today, hexylresorcinol is incorporated into cosmetic and skincare formulations for its skin-brightening and toning benefits and ability to reduce hyperpigmentation and promote a more even skin tone.

Discover easy ways to incorporate hexylresorcinol into your skincare routine.

Start with a patch test

As with any new product, apply a small amount of a skincare formula containing hexylresorcinol to a discreet area of your skin, like the bend of your elbow or inside your wrist, before applying to larger areas of skin.

Apply an evening repair cream

Apply hexylresorcinol products in the evening to allow your skin to repair and regenerate overnight, making the most of its brightening and anti-aging benefits. Try Neutrogena® Triple Age Repair Night Moisturizer with HEXINOL® technology and vitamin C to smooth the look of wrinkles, even skin tone and support a firmer, brighter complexion.

Pair with SPF in the morning

Get sun protection and hexylresorcinol benefits in one step with a formula like Neutrogena® Triple Age Repair Moisturizer Broad-Spectrum SPF 25. This attacks uneven, sun-damaged skin from both ends, helping prevent additional UV damage and hyperpigmentation with SPF while lightening existing dark spots with hexylresorcinol.

Combine with other brightening ingredients

Maximize your results with skincare products that include hexylresorcinol alongside other brightening agents, like vitamin C and niacinamide.
