To keep lips naturally pink, prioritise hydration by drinking enough water daily. Use lip balms with SPF to protect your lips from sun damage, which can lead to darkening. Avoid smoking, as it can cause lip discolouration. Eat a balanced diet with fruits and vegetables to nourish your lips and maintain their natural colour. Gentle exfoliation can remove dead skin cells and enhance the pink shade. Choose natural lip care products to keep your lips moisturised and healthy. With these simple practices, you can maintain naturally pink and beautiful lips.
