◎ Age Shield ◎ Sunscreen That Controls the Speed of Skin Aging Ultraviolet rays are categorized into UVA, UVB, and the most dangerous, UVC. UVC is almost entirely absorbed by the ozone layer, so there's no need to worry about it. The real concerns are UVA, which is directly related to aging, and UVB, which darkens skin tone. UVA, which accounts for the majority of UV rays that reach the skin, is present anywhere there is light bright enough to distinguish objects. Even on cloudy or rainy days, UVA penetrates through windows and reaches the dermis, damaging collagen and elastin, leading to sagging skin and wrinkles. UVB, on the other hand, penetrates the basal layer of the skin's surface, stimulating melanocytes — the cells responsible for pigmentation — and increasing the likelihood of dark spots. Choose the Right One As we enter a season of stronger UV rays, it is crucial to quickly find and keep a reliable sunscreen at hand. The first factors to consider are water resistance and long-lasting effects. It's important that the product remains effective even when sweating or spending extended time outdoors. For dry skin, look for a hydrating texture; for oily skin, choose a product that finishes light and fresh. Those with acne-prone or sensitive skin should select products that minimize irritation. A bonus is if the sunscreen includes skincare ingredients that brighten and improve skin health with continued use. Recently, tone-up sunscreens have become very popular — opt for one that spreads well, doesn’t clump or cake even when applied generously, and offers a natural color (HyangJang, 666). |
