After the age of 30, many problems begin to appear on our face, such as: pigmentation abnormalities (age spots, sunspots, etc.), sagging skin, fine wrinkles, facial redness, enlarged pores, and dull skin color. The combined result is that the skin starts to get older. But if we take a closer look, the skin on our body is still young and beautiful. Why? This means that these changes in our face are not really aging in the sense that we in dermatology call this aging photoaging. This means that light is causing premature aging changes in the skin. Photoaging can appear as early as before the age of 30 and may first manifest as pigmentation abnormalities and disorders, such as the appearance of dots or irregular brown pigmentation spots on the face, similar to freckles, which we call heliotrope. In some people, this pigmentation will fuse into larger brown spots. Some people also develop age spots and hypopigmentation changes. Later, the skin will gradually sag and form wrinkles, some people will also have tiny capillary dilation (facial redness), and some people’s skin will start to become rough, with large pores and even an orange peel-like appearance, etc. The combined result is that the skin gradually ages and loses its former beauty.
