“The transition between seasons is a big contributor to skin changes,” says Howard Sobel, MD, board-certified dermatologist in New York City and founder of Sobel Skin. “When the temperature and humidity drop quickly, skin works harder to maintain its hydration.” The extra effort can lead to inflammation spikes, especially if you’re prone to skin conditions like rosacea. Add gruesome indoor heating and tiresome back-to-school schedules, and your skin is probably crankier than a kindergartener in school.

Benefits of Caffeine in Skincare

That’s where caffeine comes in. You’ve probably heard that it can “wake up” your skin, but what does that truly mean? “It’s an anti-inflammatory when used topically,” says Dr. Sobel. “It can also reduce wrinkles, brighten skin, and de-puff by improving circulation in the skin.” What’s more, it’s antioxidant-rich, meaning it can help protect skin from UV damage, pollution stressors, and skin cancer. We asked dermatologists how to effectively use caffeine on every area of your skin—and if it works just as well as a cream as in your favorite mug.

For the Eyes

The under eyes are a fickle space. Factors like a restless night, a salty dinner, or even too much sun can all cause fluid retention and hyperpigmentation below your eyes. According to Dr. Sobel, caffeine is a great topical ingredient to improve puffiness and promote circulation. Results are not long-lasting, so dermatologists agree that twice a day is the magic number for best results. Keep eye cream in the fridge for some tingling morning magic, then pamper peepers at night after a long day of staring at the screen. Tip: Always tap eye treatments instead of rubbing back and forth. “Dark circles are caused by loss of volume,” says Susan Bard, MD, board-certified dermatologist at Vive Dermatology in Brooklyn, New York. “Rubbing creates shearing forces which can cause micro-cracks in the skin. It can also lead to irritation, stimulating pigment-producing cells to release its pigment.”

For the Face

Your eyes are not the only place that puffs up. Indulging in high-sodium foods can cause fluid retention, leaving you with a swollen face come morning. According to Tsippora Shainhouse, MD, FAAD, a board-certified dermatologist in Beverly Hills, California, caffeine is a vasoconstrictor. “Caffeine may temporarily constrict the superficial blood vessels in the skin, helping the skin to appear less red, irritated, and blotchy,” says Dr. Shainhouse. “By constricting the vessels, it may also help to prevent fluid seepage from those vessels, which may, in turn, help skin appear less puffy.” Caffeine is also packed with antioxidants. By applying topically, you can limit the number of free radicals (i.e., the cause of fine lines and wrinkles) that your body produces. Another anti-aging perk? amino acids. Some types of coffee, like green coffee bean oil, are full of them and can help aid in collagen and elastin production. Don’t expect to see instant results, but its soothing properties can promote these benefits when used long-term.

For the Body

Caffeine is a prime ingredient found in slimming and cellulite creams. According to Dr. Shainhouse, it can increase blood flow and is said to stimulate the removal of fatty acids from the fatty layer. But know this: While skin is smoother and more taunt after washing with caffeine products, don’t expect a cure for butt dimples. “Caffeine does not get rid of cellulite,” says Dr. Shainhouse. “It may temporarily reduce superficial fluid and inflammation in the skin, so that skin is temporarily dehydrated and less puffy, which can make cellulite visually less apparent. Caffeine does not destroy the fibrous bands that tack down the skin and trap subcutaneous tissue and fat that create the bumpy appearance of cellulite.” In short, don’t rely on caffeine as a cellulite cure. But it’s still worth adding to your body lineup; when caffeine is combined with other ingredients, it can energize the skin and optimize cellular energy to help keep the skin hydrated, conditioned, and healthy.
