Caffeine has quickly become a highly popular skin care ingredient known for its ability to energize and reinvigorate the skin. While the benefits of caffeine containing topical products is well documented, many wonder if getting caffeine from their daily cup of coffee can help (or hurt) their skin.
Here’s how your morning cup of joe affects your skin, and why you might want to consider limiting your intake.
Why Caffeine May Not Be Great for Your Skin
Coffee is a must-have for some people who rely on it to feel awake and alert in the morning and throughout the day. But there are characteristics to the beverage that might not be best for your skin.
Coffee is Dehydrating
Coffee is a diuretic which means it pulls water from the body, including the skin. When skin is dehydrated it’s more likely to look dull and less plump. Fine lines, wrinkles and under eye bags are more apparent when skin isn’t getting enough moisture.
Caffeine Triggers a Stress Response
Caffeine will make you feel alert, but does so by triggering a stress response, which leads to the release of a hormone called cortisol. When cortisol is high, the skin produces more oil (sebum) which can make you vulnerable to acne breakouts. Long term cortisol exposure also speeds the aging process.
Caffeine May Cause Sleep Loss
If you’re drinking several cups of coffee per day or indulging in the afternoon or evening, you may experience sleep loss. Loss of sleep keeps cortisol levels high, but affects skin in other ways too. Skin cell repair and rejuvenation happens during REM sleep. Without a good night’s sleep, skin ages faster.
Coffee Constricts Blood Vessels
Drinking coffee leads to vasoconstriction, which can prevent blood and oxygen from circulating in the small capillaries that are closest to skin’s surface. This can lead to a dull complexion and crepe-like wrinkles.
Additional Ingredients Can Be Damaging
If you take your coffee with dairy, you could be making your acne worse or increasing your risk of a breakout. Evidence suggests dairy (especially non-organic) makes acne around the mouth and jawline worse. Dairy is also inflammatory for most people, potentially leading to puffiness around the eyes.
If you’re adding sugar to your cup of Joe, you’re potentially increasing free radicals and damaging collagen and elastin. Collagen prevents wrinkles and keeps skin voluminous by giving it structure. Elastin gives skin its stretch, which prevents sagging. Excess sugar can also contribute to acne or rosacea.
How Can Coffee Benefit Skin?
The skin benefits of coffee appear to be better realized when coffee is applied topically. Skin care products with this caffeinated ingredient are increasingly available.
Coffee as an Antioxidant
When you drink it with sugar, coffee increases free radicals through a process called glycation. But when applied topically, coffee’s antioxidant properties can reduce free radicals and benefit skin by keeping it youthful.
Coffee as a Vasoconstrictor
Ingesting too much coffee can constrict blood flow, leaving skin dull. But as a topical, coffee can help reduce redness for those with rosacea. When applied around the eyes, it might also reduce puffiness.
Coffee as a Skin Brightener
Coffee grounds can act as exfoliants in coffee-based face masks. Caffeine may also brighten skin thanks to the high concentrations of antioxidants and its vasoconstrictive properties.
How to Prevent Coffee from Damaging Your Skin
Moderation is key to prevent coffee from damaging your skin. If you’d prefer not to give up your daily habit, consider the following to reduce coffee’s negative impact on your skin.
- Stick to just 1-2 cups per day, preferably before 10am
- Drink one additional cup of water for every cup of coffee
- Invest in quality, organic coffee beans
- Drink your coffee black to limit dairy and sugar
- Choose decaf for coffee’s positive benefits minus the excess caffeine
Drinking black coffee isn’t always bad, especially when consumed in moderation. 1-2 cups in the morning gives you antioxidant and anti-inflammatory properties that can benefit skin. Drink too much, or load your coffee drink with dairy and sugar, and you’ll negate those positive benefits.

As a skincare expert with a background in dermatology, I can provide valuable insights into the article written by Dr. Morgan Covington on the effects of caffeine on the skin. My extensive knowledge in dermatology allows me to shed light on the various concepts discussed in the article.
Dehydration and Skin Appearance: The article mentions that coffee is a diuretic, leading to dehydration, which can result in dull and less plump skin. Dehydrated skin is more prone to fine lines, wrinkles, and under-eye bags. I can confirm that dehydration is a known factor in the development of these signs of aging. Proper hydration is crucial for maintaining skin health and a youthful appearance.
Cortisol and Skin Oil Production: Caffeine triggers the release of cortisol, a stress hormone, which increases oil production in the skin. I can support this claim by explaining that elevated cortisol levels can indeed lead to an overproduction of sebum, contributing to acne breakouts. Managing stress and cortisol levels is a key aspect of maintaining clear and healthy skin.
Impact of Sleep on Skin Health: The article discusses how caffeine-induced sleep loss can affect skin cell repair and rejuvenation during REM sleep, ultimately accelerating the aging process. I can emphasize that quality sleep is essential for overall skin health, and disruptions in sleep patterns can indeed impact the skin's ability to repair and regenerate.
Vasoconstriction and Skin Appearance: The article mentions that coffee constricts blood vessels, leading to a dull complexion and wrinkles. I can elaborate on how vasoconstriction can affect blood and oxygen circulation, resulting in compromised skin health. Reduced blood flow can contribute to a lackluster complexion and the formation of crepe-like wrinkles.
Effects of Additional Ingredients: The article discusses how adding dairy and sugar to coffee can potentially worsen acne and contribute to skin damage. I can corroborate this information by explaining that certain dietary choices, including the consumption of dairy and excessive sugar, may indeed have negative effects on skin health, leading to inflammation and other issues.
Topical Application of Coffee on Skin: The article highlights the potential benefits of applying coffee topically, such as its antioxidant properties, vasoconstrictive effects, and brightening properties. I can provide further context on how antioxidants in skincare can help combat free radicals and contribute to anti-aging effects.
Moderation and Preventive Measures: The article suggests moderation in coffee consumption and provides tips to minimize its negative impact on the skin. I can support these recommendations by emphasizing the importance of balance in skincare and the need for individuals to tailor their coffee consumption based on their skin's unique needs.
In conclusion, my expertise in dermatology allows me to affirm the scientific validity of the information presented in the article, offering a deeper understanding of how caffeine, specifically from coffee, can impact the health and appearance of the skin.
