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

What it is
Carmine is a red pigment extracted from the dried and crushed bodies of female Dactylopius coccus costa insects, which live on cactus plants. The main coloring agent is carminic acid, which is processed to produce a stable, vibrant dye.
How it works
In cosmetics, carmine is added as a colorant to impart a range of red, pink, or purple tones. It is mixed into the product base (like a lipstick wax or powder) and provides long-lasting, intense color that does not fade easily. It is approved for use in eye area products in many regions.
Pros
Vibrant color payoff
Carmine delivers intense, long-lasting red and pink shades that are hard to achieve with many synthetic alternatives.
Natural origin
Derived from a natural source, carmine is often preferred by consumers looking to avoid synthetic chemicals in their makeup.
Cons and cautions
Not vegan-friendly
Since carmine is made from crushed insects, it is not suitable for vegans or those who avoid animal-derived ingredients.
Potential allergen
A small percentage of people may experience allergic reactions, such as contact dermatitis or hives, especially if they have existing insect allergies.
Best for
- People who want vibrant, natural-looking red or pink makeup
- Those who prefer natural colorants over synthetic dyes
Use caution if
- Vegans and vegetarians
- Individuals with known allergies to insects or insect-derived products
