Vaseline, known for its moisturizing properties, can contribute to making lips appear pinker. It doesn't directly change the pigment of your lips, but it can help to enhance their natural color by promoting a healthy, hydrated appearance.
While Vaseline itself is colorless, its ability to soften and smooth chapped lips can make them appear more vibrant. This is because dry, flaky lips often appear duller in color. By sealing in moisture and protecting lips from further dryness, Vaseline can improve their overall appearance, making them look more pink and healthy.
Additionally, Vaseline offers specific products, like Vaseline Lip Therapy Rosy Mini, which contain a sheer pink tint. These tinted versions can add a subtle flush of color, further enhancing the pinkness of your lips.
However, it's important to note that Vaseline won't make your lips drastically pinker or change their natural color. The effect is more about restoring a healthy, hydrated glow that emphasizes their natural pink tones.
