Ingredient review
Acid Yellow 3 Aluminum Lake
INCI: CI 47005
A widely used synthetic yellow pigment that adds color to makeup but offers no skincare benefits.
In plain English
This is a man-made yellow dye that has been turned into a powder (a lake) so it mixes well with oils and waxes in makeup. It's what gives some lipsticks, eyeshadows, and blushes their yellow or golden tones. It doesn't treat or improve your skin—it's purely for color.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic organic pigment created by combining a water-soluble yellow dye (Acid Yellow 3) with an aluminum salt, making it insoluble and suitable for use in oil-based and powder cosmetics.
How it works
As a lake pigment, it is dispersed throughout the product's base (like a lipstick or eyeshadow) to provide a stable, uniform yellow color that doesn't bleed or migrate. It sits on the surface of the skin or lips and does not penetrate.
Pros
Vibrant color payoff
Gives a bright, consistent yellow shade that stays true in various lighting conditions.
Good stability
Resists fading from light and heat, so your makeup keeps its color longer.
Cons and cautions
No skin benefits
This ingredient is purely cosmetic and does not hydrate, protect, or improve skin health.
Potential staining
Can temporarily stain skin or clothing, especially in high-concentration formulas.
Best for
- Anyone looking for a yellow pigment in their makeup
- People who prefer synthetic colorants over natural ones for consistency
Use caution if
- Those with known allergies to coal-tar dyes (rare, but possible)
