Dull skin can be caused by a variety of factors, including dehydration, lack of exfoliation, and poor circulation. If your skin looks lackluster and tired, it may be a sign that it needs some extra care and attention. To combat dullness, it's important to focus on hydration, gentle exfoliation, and promoting circulation. Look for skincare products with ingredients like hyaluronic acid to boost moisture, and consider incorporating a gentle exfoliating treatment into your routine. Additionally, regular exercise and facial massage can help improve circulation and bring a healthy glow back to your skin.
