👉 Brighteners are substances that can help improve the appearance of your skin by brightening it and making it more radiant. They work by stimulating the production of collagen, which is a protein that helps to maintain healthy skin texture and elasticity. Brighteners also have anti-aging properties, which means they can help to reduce the signs of aging like fine lines and wrinkles. Brighteners are generally derived from natural sources such as fruits, vegetables, and flowers. They are commonly found in cosmetics products and skincare treatments
