Cucumber Extract: A Versatile Ingredient for Skin Care Benefits

31 March 2025


Cucumber Extract in Skin Care




Cucumber



Cucumber extract from the (Cucumis sativus) is a very common ingredient in skin care products like acne cleansers, anti-aging moisturizers, and dark spot treatments.




It has broad benefits for a number of skin concerns, but is most commonly recommended to treat conditions like acne or inflammation.



When prepared for skin care, this product is usually odorless and thin, which is slightly unusual for a product in the essential oil category.




When used raw, cucumbers have a much higher water content than cucumber extract and while maintaining the same benefits; this is why people commonly put cucumber slices on their eyelids.



If you’re thinking about using cucumber extract in skin care, read below and take our quiz to find your Baumann Skin Type so you can find the right regimen for your skin!




What is cucumber extract?



Cucumber extract is the fruit of the cucumber plant blended, steamed, and distilled to remove most of the water content.




What is left is a thin, usually odorless liquid full of many antioxidant, anti-inflammatory, and antimicrobial compounds.



Because it is a thin, plant based oil with very low fatty acid content, it is considered an essential oil.




Even though it contains some unsaturated fatty acids, it is not considered a dry oil because it does not have enough fat to solidify at all in room temperature.



This liquid is alkaline, meaning it is basic (opposite of acidic, not “standard”).




It is a safe and common ingredient that has been used for centuries for various dietary and medicinal purposes. (1)



What is cucumber extract?




What are the active compounds?



Cucumbers are an extremely diverse organism in terms of chemical composition. They contain water, flavonoids, lignans, vitamins, some fatty acids, and minerals of many kinds.




To begin with, cucumbers are a great source of vitamin B, vitamin C, and vitamin E, and vitamin K. (4,5)



Triterpenes present in cucumber extract have been studied to aid in healing wounds. (6)




Flavonoids such as apigenin, luteolin, quercetin, and many other antioxidant compounds such as beta carotene are also present in cucumbers.

There is a very high amount of potassium in cucumbers, as a result, cucumbers are alkaline (high pH).

Even though the general pH within a cucumber is alkaline, it also contains the alpha hydroxy acids lactic and glycolic acid, as well as the beta hydroxy acid salicylic acid. (8)

The alkalinity of cucumber provides its antimicrobial effect.

Lastly for the sake of this blog, there is a small concentration of linoleic and oleic fatty acids. (9)

Linoleic fatty acid is good for moisturizing and repairing the skin barrier.

Oleic acid is used for aiding ingredient absorption.

Many other compounds are present in cucumbers, and many of them are also antioxidant, anti-inflammatory, and antimicrobial.

Benefits of cucumber extract in skin care

Benefits

The numerous phytochemicals (plant specific compounds) present in cucumber extract offer antioxidant, anti-inflammatory, and antimicrobial benefits.

Cucumber extract has notable abilities to scavenge and eliminate free radicals in the skin. (7)

Studies have also found that cucumber extract can reduce the production of sebum in the skin, making it a good choice for oily skin types.

Many of the soothing properties of cucumber oil make it a popular choice for burn ointments.

Studies have found some evidence that cucumber extract might have tyrosinase inhibiting effects as well, though it is not very potent at lightening skin. (3)

The triterpenes in cucumber extract are known for their ability to assist in wound healing. (6)

Overall, the benefits of this ingredient are wide in variety, although it is seemingly a jack of all trades, yet master of none.

In general, there are very few reasons to avoid cucumber in your skin care.

It can function as a respectable antimicrobial, antioxidant additive to a plethora of product types.

Side-effects

Since cucumbers are alkaline, overuse of them on your skin can disrupt the natural slight acidic pH environment of your skin. Additionally:

It can interfere with the effectiveness of your low pH cleansers.

If your skin becomes too alkaline, it can feel sensitive and enflamed.

It is very uncommon to have an allergy to cucumbers, but it is not impossible.

As with many other antimicrobial ingredients, extreme overuse can result in some damage to your microbiome.

Is it safe?

Cucumber extract is safe to use as a part of your skin care regimen as long as you do not have an allergy to it.

The EWG rating of cucumber extract is “1”, which means there are no common concerns associated with its use in cosmetics.

The Cosmetic Ingredient Review panel also deems it safe for use in cosmetics.

Take the Quiz

What is cucumber extract used for?

Uses

Cucumber has many potential benefits in skin care, so it can be found as an additive in many product types such as:

Acne cleansers

Hyperpigmentation treatments

Inflammation and soothing creams

Burn treatment creams and serums

Wrinkle treatment products

For acne

Cucumber extract is a good choice for acne treatments because it is antimicrobial, non-comedogenic, and helps with excess sebum on the skin.

Because cucumber extract is alkaline, it creates an environment on the skin that bacteria cannot survive in.

At the same time, the anti-inflammatory compounds in this ingredient alleviate redness on clogged pores.

Studies have shown that cucumber can temporarily interfere with sebum production on the skin, which lowers the chances of future acne breakouts. (1)

For dry skin

Many products designed for dry skin types contain cucumber extract for its anti-inflammatory properties.

Cucumbers are mostly made of water which makes them effective at hydrating certain thin parts of the skin like the eyelids.

Cucumber extract does not strip any oil from the skin when used alongside fatty oils like jojoba or safflower oils.

For hyperpigmentation

Cucumber extract contains hydroxy acids which are associated with skin lightening treatments, however these acids are too weak in the alkaline environment to trigger any significant exfoliation.

Instead, cucumber extract expresses tyrosinase inhibiting activity, meaning it directly interferes with the production of melanin.

It is a very weak skin lightener, so it will not make a significant difference to dark spots on its own.

If you’d like to use cucumber extract as a part of your hyperpigmentation treatments, we recommend using it alongside a more potent skin lightening ingredient.

For wrinkles

Cucumber extract has a notable amount of antioxidant compounds which are effective at binding and eliminating aging-related free radicals on the skin.

In addition, it has been used in treatments of sunburns, which could otherwise cause genetic damage to skin that leads to aging. (3)

Supplemental as cucumber extract might be to an anti-aging skin care regimen, it won’t fix wrinkles on its own.

For significant results you should always use anti-aging ingredients in combinations.

Some generally common and effective anti-aging ingredients in skin care are:

Coenzyme Q10

Hyaluronic acid

Resveratrol

Cucumber extract for wrinkles

Difference between cucumber extract and cucumber seed oil

Cucumber seed oil is pressed specifically from the seeds, not the fruit, of the cucumber.

This oil is richer in moisturizing fatty acids than cucumber extract is, and has a slightly thicker consistency.

Though uncommon in skin care, it might serve in certain moisturizing or cleansing products due to its concentrations of linoleic and oleic acids.

It is not as efficient to separate the seeds of the cucumber for processing, so the entire fruit is usually used to make extracts in skin care.

Products

Cucumbers are a jack of all trades in skin care, good for most skin concerns, but not particularly effective at anything by itself.

If you are looking to include cucumber extract in your skin care routine, make sure you aren’t using ingredients with low pH alongside it, because they will neutralize each other and be less effective.

Keep how you should layer your skin care ingredients in mind.

DQH Knowledge drop: In your 20s, your skin cell turnover decreases. (Cell turnover is a key component in keeping your skin youthful.) You know what else slows down? Your collagen production. Starting in your 20s, collagen decreases by about 1 percent per year. Should you want to prevent fine lines and wrinkles, start by eliminating behaviors that contribute to premature aging. “If it’s bad for you, it’s bad for your skin,” says dermatologist Michel Somenek. “Cigarette smoking reduces blood flow to the skin and causes premature wrinkling and a dull skin texture. Making the repeated pursed motion to inhale can also cause smoker’s lines. Alcohol and recreational drugs are toxins for the skin that damage its cellular structure and DNA,” Somenek tells us. “The faster you eliminate vices while you are young, the better chance your skin and body have to recuperate.” Also, adopting an anti-aging routine in your 20s is key. After all, the best offense is a good defense. We spoke to Somenek and experts Joshua Ross and Audrey Kunin to find out more. Keep reading for the best anti-aging products for your 20s, according to skincare professionals. Sunscreen “We all know that the sun is the number one cause of skin aging and starting the prevention in your 20s is very important,” Ross says. “The majority of your sun damage won’t start to appear until you’re in your 30s, so don’t wait until you see it surface or you’ll be behind the curve. Stay ahead of it with a good-quality zinc-based sunscreen worn daily.” Farmacy Green Defense Daily Mineral Sunscreen An invisible sunscreen with SPF 30, plus botanical extracts meant to protect skin with tons of antioxidants. Bonus: It’s clean and fine to use under makeup. Bareminerals Complexion Rescue™ Tinted Moisturizer Broad Spectrum SPF 30 Although we recommend you use your SPF and moisturizer separately, we also understand moments when you don’t have time or energy for that extra step. For those times, this bareMinerals moisturizer is a great thing to have on hand. Vitamin C Serum “A great introduction to anti-aging is to start with a vitamin C serum in your morning skincare routine,” Ross says. “It’s a powerful antioxidant that will neutralize free radicals and brighten the skin.” He adds that it’s a great way to counteract the effects of the sun’s harmful rays, which, as previously mentioned, are among the biggest causes of premature aging. Drunk Elephant C-Firma™ Vitamin C Day Serum The Drunk Elephant C-Firma is a lightweight serum that promises to give skin a glow by combining the brightening powers of vitamin C with ferulic acid, l-ascorbic acid, and vitamin E. The included sodium hyaluronate is meant to replace hydration loss, so you shouldn’t have to deal with any irritation. Sunday Riley C.E.O. Rapid Flash Brightening Serum This potent serum is jam-packed with vitamin C (15 percent, to be exact), which means it’s a potential superstar at both brightening skin and dousing it in antioxidants. Peptides Using peptides on your skin has many benefits, says Somenek. “The skin barrier is what defends the body against pollution, UV rays, bacteria, and toxins. It can be damaged by several everyday factors. Using topical peptides aids in building a stronger barrier,” he says. “Peptides comprise elastic fibers, which are a type of protein. These fibers help to make skin appear taut and firm. Peptides can also help repair damaged skin, relieve inflammation, and even out skin tone. Some peptides can kill acne-causing bacteria that is common in 20-somethings.” Kunin agrees, saying, “Peptides are an excellent entry point for supporting collagen.” She recommends looking for face and eye treatments that contain these collagen-boosting powerhouses. Charlotte Tilbury Magic Eye Rescue Cream This Charlotte Tilbury super-emollient eye cream has a base of coconut oil and shea butter (read: it’s incredibly hydrating). Botanicals plus peptides are meant to help reduce dark circles and boost collagen, respectively. This creamy moisturizer serves up potent collagen-boosting peptides and pycnogenol, and antioxidant-rich vitamin C. “Instead of sitting on top of the skin, peptides penetrate the outer layer so they go deep. The ‘signals’ they send tell the cells to produce elastin and collagen, which are needed for youthful-looking skin,” explains Somenek. At-Home Peel Pads Remember that skin cell turnover fiasco we talked about earlier? One way to help support it is by exfoliating. “Exfoliation is important to help keep skin fresh and luminous,” Kunin says. She recommends using at-home peel pads as an easy and effective way to exfoliate. “The goal in your 20s is to fight the slowing pace of cell turnover. It is wise to use products that gently exfoliate, yet still remove oil and other impurities. Products that have Alpha Hydroxy Acids (AHA) or Beta Hydroxy Acids (BHA) are a good choice.” According to Somenek, you should only exfoliate two to three times a week. “People of all ages are guilty of over-exfoliating and that can be too much of a good thing,” he says. Dermadoctor Kakadu C Intensive Vitamin C Peel Pad A few swipes of this Derma Doctor powerful peel pad promise to leave your skin glowing and smooth, thanks to the seven (yes, seven) types of chemical exfoliants, including AHA and BHA. It also contains vitamin C via Kakadu plum extract for added brightening and antioxidant protection. KEY INGREDIENTS Kakadu plum extract is sourced from the Kakadu plum, a fruit grown in northern Australia. It contains vitamin C, which restores the skin’s natural barrier, increases collagen production, and soothes irritation. Dr. Dennis Gross Skincare Alpha Beta® Universal Daily Peel Pads These are the gold standard of peel pads, with a cult following and over 900 five-star reviews on Sephora. They’re easy to use and contain a blend of anti-aging exfoliating acids. Emollient Night Cream “In your 20s, you need to start upping the hydration in your skincare routine. You may have been cautious of over-moisturizing because of acne in your teens, but as you enter your 20s, your skin transitions and becomes drier,” Ross says. “I recommend an emollient night cream added into your evening skincare regimen.” “Twenty-somethings need to make sure that they are not using creams that will clog their pores and cause excess oil production,” says Somenek. Opt for non-comedogenic products. Cerave Skin Renewing Night Cream One great choice is the CeraVe Skin Renewing Night Cream, which is a non-comedogenic night cream that leaves skin soft and glowy. It combines the moisturizing powers of ceramides and hyaluronic acid. RoC Retinol Correxion Max Hydration Creme “The best night cream ingredients contain retinol, benzoyl peroxide, and/or salicylic acid or hyaluronic acid. The goal is to moisturize, yet remove excess oil,” says Somenek. This Roc Retinol Correxion cream fits the bill as it contains both hyaluronic acid and retinol so it promises to moisturize while also being non-comedogenic.
