Shoppers Say This $15 Serum Is ‘Great’ for ‘Mature’ Skin and Helps Depuff Under Eyes

It’s like giving your face a cup of coffee.

Caffeine does more than just provide energy with your morning cup of joe. In fact, it’s a powerful ingredient in a variety of anti-aging skin care products, including some of the best eye creams for dark circles.

It’s also a key ingredient in Tru Skin’s Caffeine Face Serum, which customers say brightens the eye area and promotes a radiant complexion.

Tru Skin’s Caffeine Face Serum contains the energizing ingredient matcha green tea, and is also rich in skin-protecting antioxidants like the polyphenol EGCG.

When applied topically, the stimulant can reduce puffiness and dark circles by constricting blood vessels, Marisa Garshick, M.D., F.A.A.D., a board-certified dermatologist in New York City, tells Prevention.

“It also has antioxidant properties that can protect the delicate eye area from environmental stressors.” Caffeine can also temporarily boost overall blood flow to the skin, which can reduce wrinkles and help you look more alert and refreshed, adds Janiene Luke, M.D., a board-certified dermatologist in Loma Linda, California.

The serum also contains niacinamide, a form of vitamin B3, which minimizes the appearance of enlarged pores, improves skin texture and redness, and promotes hydration.

Two key active ingredients in one bottle do all the important things you would normally expect from a complete skincare product. Other key ingredients include herbal actives like ginseng, which has been shown to have anti-inflammatory properties.

Customers also recommend TruSkin’s Caffeine Face Serum. “I started using the Caffeine Face Serum under my eyes morning and night. It improved the dark purple dark circles I had since childhood,” one customer wrote.

I’m over 65 and have tried a lot of products. I was really surprised when I noticed a change. My dark circles weren’t as dark anymore. I asked myself, “Is this real?”

It moisturizes my eyes but doesn’t leave a sticky residue when it dries, so my under-eye concealer goes on smoothly. I’ve tried a lot of expensive brand name products to combat dark circles. What a relief to finally find something that works as promised. ”

One reviewer reported improvements in skin texture, skin tone, and overall appearance after use. Another said the serum left a tingling sensation, “like I spilled a pot of coffee on my skin—in a good way.”

Others appreciated how gentle it was on sensitive skin and how it didn’t cause breakouts, “which is great,” she wrote. The serum is also suitable for people of all ages.

“I have dry, mature skin, and TruSkin’s Caffeine Face Serum brought dramatic results,” raved another reviewer. “It invigorated my skin and made it look moisturized, firm, and radiant.”

It’s important to note that the immediate effects of caffeine in skincare are only temporary. Using this serum regularly is the best way to achieve the desired results.

However, if you use it every morning as directed, it could become a new, regular part of your routine.
