Overall, it has been found that dipping your face in ice water does have many benefits for your skin. It has been found to have properties that can help reduce puffiness and inflammation. According to The Skimm, “When your skin interacts with super-cold temperatures, the blood vessels beneath the surface constrict, reducing redness, swelling, and puffiness. When your face returns to its normal temperature, the capillaries reopen and you’re left with a refreshed, healthy flush” (Holden and Knot). Many people argue that it's not an immediate transformation, but the main immediate effect is that it can make you feel more awake and energized. According to Bill Bachand at RENU Therapy “Submerging your face in ice water activates the parasympathetic nervous system, reducing stress and anxiety, and promoting relaxation by lowering your heart rate” (RENU Therapy, 2024). This actually proves that the benefits of dipping your face in ice water can go far beyond just the appearance of your skin but can help you feel refreshed and energized. Although there is proof behind this, it isn’t for everyone. According to Sara Choi from Healthline (2024), “Would I do this again? No. The ice water facial did not help me achieve any noticeable changes to my face. I felt I looked the same before and after the week. I also felt this was a waste of water to feel more awake. I usually wash my face in the morning with water on a washcloth, which achieves the same effect.” This proves that this method doesn’t work the same for everyone and many factors can go into it, like skin types. In the end, dipping your face in ice water might not be the ideal magical skincare hack, but it’s an easy way to wake up your skin leaving it refreshed, but it might be better to not expect any major changes.
