Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

moderateThere is useful support, but formula details and claim strength still matter.
What it is
Pigment Red 190 is a synthetic organic pigment from the class of azo dyes, specifically a disazo pigment. It is chemically engineered to produce a bright, stable red color that resists fading from light or heat.
How it works
In a cosmetic product, Pigment Red 190 is dispersed as fine particles throughout the formula. These particles sit on the surface of the skin or nail, reflecting and absorbing light to create a visible red color. It does not penetrate the skin or interact with biological processes.
Pros
Vibrant color payoff
Provides a strong, bright red shade that stays true in various lighting conditions, ideal for bold makeup looks.
Good stability
Resists fading from sunlight and heat, so your makeup color remains consistent over time.
Cons and cautions
No skin benefits
This ingredient is purely a colorant and does not hydrate, soothe, or protect the skin in any way.
Potential for staining
If not properly formulated or removed, it can leave temporary stains on skin or clothing.
Best for
- Anyone looking for red color in makeup products
- People who prefer synthetic colorants over animal-derived ones like carmine
Use caution if
- Those with known sensitivity or allergy to azo dyes (rare)
