A lesser-known skin care ingredient is reported to be safe for all skin types and effective in fading dark spots and brightening complexion. However, the specific ingredient is not consistently identified across reports, with some outlets mentioning various dark spot correctors and others discussing different skincare ingredients, such as centella asiatica and vitamin C serums. The effectiveness of these ingredients is reportedly backed by dermatologists and testers, but some skincare hacks, like using baking soda, are warned against due to potential skin damage.
