Skin can appear to glow due to a variety of factors, including hydration, exfoliation, and a healthy lifestyle. When the skin is well-hydrated, it appears plumper and more radiant. Exfoliation can help to remove dead skin cells, revealing fresher, brighter skin underneath. A healthy lifestyle, including a balanced diet and regular exercise, can also contribute to glowing skin by improving circulation and reducing stress. Additionally, certain skincare products, such as serums and masks, can help to brighten and improve the texture of the skin.
