Even though they are sometimes confused, tinted oils, glosses, and lip tints are different products that are not formulated in the same way. The tinted oils rely on a base of plant-derived or synthetic lipids with strong affinity for the skin and capable of restoring the lips’ hydrolipidic film. These often include jojoba, castor, or almond oils rich in unsaturated fatty acids, as well as lightweight esters that provide a non-greasy finish. Tinted oils also contain dispersed pigments responsible for the color effect. Finally, tinted lip oils incorporate film-forming agents that aid in smooth product application and water retention in the skin. These ingredients also help thicken the oil formula, creating a silky, smooth texture that glides effortlessly over the lips.
Glosses, for their part, are formulated around a gelled or polymeric phase. Their viscous texture often comes from silicone- or cellulose-derived polymers that trap pigments and pearlescent particles while forming a glossy film on the lip surface. Mineral or plant oils are included in varying proportions to enhance the product’s slip properties. Some “treatment” glosses are enriched with humectants to improve application comfort. However, most remain designed for a luminous finish rather than a restorative effect.
Finally, lip stains rely on an aqueous or hydroalcoholic phase in which the pigments are dispersed using surfactant agents. Their light texture stems from the presence of volatile solvents, which evaporate rapidly to leave a thin colored film on the lips. This particular formulation—composed of water-soluble pigments, film-forming polymers, and one or more volatile solvents—is responsible for the long-lasting wear of lip stains, as well as their slightly drying effect on the lips, although some recent products are beginning to incorporate light hydrating active ingredients, such as pentylene glycol or lactate derivatives.
The formulation of each product dictates its texture, wear, and benefits: tinted oils are optimized for nourishment, glosses for shine, and inks for durable pigment retention.
