The concept of "whitening" has evolved to this day far beyond simply attempting to lighten the skin tone. It has become a comprehensive beauty approach aimed at improving skin texture and combating signs of aging, meaning you may need whitening more than you realize. Basic Whitening: Improving dull complexion and reversing short-term sun-induced darkening. Accelerating exfoliation When the skin is overly stressed, normal metabolism is disrupted, causing accumulated melanin in the epidermis, leading to a dull complexion. Timely removal of old keratin can help brighten the skin, ensure full absorption of whitening ingredients, and make the skin purer. Promoting microcirculation Enhancing skin brightness Healthy skin has smooth blood circulation, naturally presenting a rosy and translucent glow. When lacking sleep or aging occurs, blood circulation slows down, making the skin appear dull. Therefore, for those with a dull complexion, a whitening product that promotes skin blood circulation is essential. Use components such as citrus polyphenols and vitamin C to fight oxidation and promote microcirculation, while pairing with appropriate massage to create a rosy-white complexion. Intensive whitening care after tanning After prolonged outdoor activities or summer, everyone will get "tanned", making this the easiest time for whitening treatments to be effective. However, immediate whitening after sun exposure is not recommended; instead, hydration and soothing care should be done first until the skin reaches a resilient state before starting the whitening process. At this point, using an intensive whitening mask for a week can accelerate melanin metabolism, helping the skin quickly return to its original brightness. If you want to whiten rapidly after summer, it's suggested to use an intensive whitening essence for 28 days, so you won't still look like a fisherman who just returned from the beach as winter approaches.
