Give coffee to your skin? –

Have you ever heard of ‘coffee pack’ or ‘coffee scrub’? On social media ‘TikTok’, videos of skin care with caffeine in coffee are trending. Based on data from Everdie, let’s see if this is a well-founded claim.

Dr. Jeffrey Hsu, a dermatologist in Chicago, USA, said, “Caffeine constricts blood vessels, making them smaller and tighter, reducing blood flow to the skin, reducing swelling and making it appear brighter and more dense.” That is why, if you manage your eyes, face, and body with caffeine, you will look smooth without wrinkles.

In August 2020, a study published in the International Journal of Cosmetic Science found that ‘caffeine molecules are so small that they can penetrate the top layer of the skin, so caffeine molecules can get into the skin and really work’. However, Dr. Huh said, “The key is the proper formulation of caffeine.” In other words, “to be effective, caffeine must be used in high concentration doses.”

Dr. Ife Rodney, a dermatologist in Maryland, said, “Caffeine is primarily circulatory, so it works quickly, protects the skin from oxidative stress, and has anti-inflammatory properties.” It can also protect against damage such as fine lines after sun exposure.

“It helps when caffeine is applied after exposure to UVA and UVB rays,” he said. However, he emphasized that although this effect is immediate, the effect diminishes over time. “Caffeine is beneficial to the skin only for a short period of time after drinking a cup of coffee,” he said. He noted the need for other active ingredients to help regenerate the skin: aloe, tea tree oil, shea butter, vitamin C, and jojoba oil. He also recommends age-appropriate cleansing with salicylic acid, serums with vitamin C and hyaluronic acid and niacinamide, moisturizers with ceramides, and sunscreen.

Above all, people who are sensitive to caffeine should be careful. Caffeine increases blood flow and can irritate the skin by increasing blood flow, so it is recommended to put a small 10-cm patch behind the ear or on the jaw line to test it first and consult a doctor first.
