La Sincia Trance Tint Lip 3.5g

Even though it’s a grey lipstick, it turns pink when you apply it because it’s formulated to change colour in response to the moisture content, pH and body temperature of each individual lip!
The more alkali and moisture there is, the stronger the red colour becomes. Tint means “to dye,” and instead of the pigments used in regular lip products,
tint lip products use dyes to color the keratin. Tint lip products dye the surface of the skin on your lips, but this can be removed with our cleansing gel.
In addition, the metabolism of the skin on your lips is active, so even if the surface is slightly colored, the keratin will peel off quickly, so you can use it with confidence.
