A TikTok trend promoting frozen cucumbers as a skincare tool for a radiant complexion is raising concerns among experts. While cucumbers can hydrate and soothe skin, dermatologists caution that freezing them may cause irritation, especially for individuals with conditions like eczema or acne. The temporary benefits, such as reduced swelling and a cooling effect, can also be achieved using an ice cube. Experts recommend consuming cucumbers for better skin health, rather than applying them directly.
