Skincare graded by science, not marketing
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
Why a traffic light?
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
Works
Multiple RCTs, evidence-based dermatologists recommend. Retinol, niacinamide, glycolic acid
Uncertain
Limited studies or weak effect. Bakuchiol, most peptides, plant extracts
Doesn't work
Molecule can't penetrate skin, or inefficacy is proven. Topical collagen, PDRN in creams
How it works

The extension finds the ingredient list automatically and colors each component.
Make a decision
The summary panel shows how many ingredients have real evidence behind them and how many are filler.
What Evigrade does
Position-based analysis
INCI lists run in descending order of concentration. If alcohol or fragrance lands in the top five, the extension flags it.
Irritation potential
Every component carries an irritation score with a note for sensitive or rosacea-prone skin.
Pregnancy safety
Flags ingredients to avoid during pregnancy: retinoids, salicylic acid above 2%, hydroquinone.
Manual input
Paste an ingredient list from packaging, a Reddit thread or anywhere else and get the same grading.
Supported stores
More stores coming based on user requests.

Where the data comes from
Evigrade is built on peer-reviewed clinical trials, Cochrane systematic reviews and dermatology guidelines. Every ingredient is reviewed by a practicing physician on the editorial team. Full citations live on each ingredient page – no hand-waving, no proprietary scores.

Is it free?
Yes, fully. A paid tier with skin-type personalization and goal-based routines is planned later this year. The core ingredient grading stays free forever.
Why doesn't it work on my site?
We currently support 10 retailers: Sephora, Ulta, Cult Beauty, Boots, Lookfantastic, Beauty Bay, iHerb plus Goldapple, Wildberries and Ozon for the Eastern European audience. Want your store added? Drop us a line.
Do you collect user data?
No. The extension sends only the ingredient list from the current product page to our server for matching. No browsing history, no email, no account, no analytics SDK.
Why a traffic light instead of A–F?
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.
