A free Chrome extension that grades every ingredient on Sephora, Ulta, Cult Beauty, iHerb and six other stores. Green, yellow, red – based on clinical trials, not brand copy. No signup, no tracking
Letter grades (A–F) borrow from pharmacology, where multiple RCTs are required to earn a top mark. Almost no cosmetic ingredient meets that bar, so the grade becomes meaningless. Three colors honestly reflect how much real evidence each ingredient has
Multiple RCTs, evidence-based dermatologists recommend. Retinol, niacinamide, glycolic acid
Limited studies or weak effect. Bakuchiol, most peptides, plant extracts
Molecule can't penetrate skin, or inefficacy is proven. Topical collagen, PDRN in creams
On Sephora, Ulta, Cult Beauty, Boots, iHerb and six other supported retailers.
The extension finds the ingredient list automatically and colors each component.
The summary panel shows how many ingredients have real evidence behind them and how many are filler.
INCI lists run in descending order of concentration. If alcohol or fragrance lands in the top five, the extension flags it.
Every component carries an irritation score with a note for sensitive or rosacea-prone skin.
Flags ingredients to avoid during pregnancy: retinoids, salicylic acid above 2%, hydroquinone.
Paste an ingredient list from packaging, a Reddit thread or anywhere else and get the same grading.

Letter grades borrow from pharmacology. Cosmetic research rarely hits that bar, so almost nothing would earn an A and the scale becomes meaningless. A traffic light is honest about how much real evidence each ingredient actually has.
