Pigments

A pigment is a substance able to absorb specific wavelengths of light and reflect others, thereby giving it a distinct colour. They can be natural, such as melanin in the skin or chlorophyll in plants, or synthetic and are utilised in various fields such as skincare.

FAQ about pigments

Are mineral pigments safer for sensitive skin?

Mineral pigments are often considered safer for sensitive skin, but in reality, there is no scientific evidence to support this claim.

What are the applications of pigments in the cosmetic industry?

Pigments are utilised in the skincare industry to add colour to products, such as foundations, lipsticks, eyeshadows, and nail polishes, and can provide various effects such as a mattifying or pearlescent effect.

Can pigments cause skin irritations?

Yes, certain pigments can cause skin irritations, particularly on sensitive or reactive skin types.

Are dyes similar to pigments?

Although there is no official distinction in the European cosmetic regulation, pigments are traditionally associated with insoluble inorganic powders, while dyes are generally considered as soluble organic compounds.

Do pigments and dyes provide the same colour intensity?

No, the pigments typically provide a more intense and stable colour than dyes, which are often more transparent and can degrade over time or under the effect of light.

How to choose between a pigment and a dye in cosmetic formulation?

The choice depends on the desired effect: pigments are favoured for opaque, long-lasting, and more covering colours, while dyes are used for more translucent and vibrant shades, often in liquid formulations.
