[ 11 · METHODOLOGY ]
How we built the Index
01 · COLLECT
1,510 product records from the DemythSkin database, each with an ingredient list traced to a real source.
02 · CLEAN
285 duplicate records merged into one row per product; 162 records with unconfirmed ingredient lists left out. 1,225 products remain.
03 · PRICE
The lowest US-dollar price on a US retailer or brand page for the full-size product. 989 products confirmed; no estimates.
04 · ANALYSE
Efficacy and safety scored from the ingredient list (0–5). Spearman rank correlation; Mann-Whitney tests for group differences.
LIMITS
- Scores rate the formula, not clinical results, texture or how a product feels.
- The database is products people scanned plus ones we added, not a random sample of the market.
- Prices aren't adjusted for size; a third of products have a usable size.
FULL DEFINITIONS →
- Budget = $30 or less. Expensive = $60 or more.
- Matched or beaten: a product in the same category priced $30 or less that scores equal or higher on both efficacy and safety.
- Overpriced: priced $60+, efficacy at or below its category's median; ranked by price ÷ the category's median price (categories with 20+ priced products).
- Added fragrance: an ingredient named parfum, fragrance, aroma or perfume. Fragrance allergens are the EU-labelled list (linalool, limonene, citronellol, geraniol and others). Essential oils are oils from aromatic plants, not carrier oils.
- Ingredient tiers: S and A are the top actives; C and D are low-value ingredients that don't do the work; the rest are bases and fillers.
- Brands: brands with 5+ priced products, compared by median price and average efficacy.
- Statistics: Spearman rank correlation with a 1,000-sample bootstrap interval; Mann-Whitney U for group differences.

Questions about the Index
Does expensive skincare work better than cheap skincare?
Not on formula. Across 989 products with a US price, price and efficacy score have essentially no relationship (Spearman ρ = 0.05), and 96% of products at $60+ are matched or beaten by a product at $30 or less.
What do the efficacy and safety scores measure?
They rate the ingredient list: which actives are present, where they sit on the label, and which ingredients raise irritation concerns. They don't measure clinical results or how a product feels.
Which skincare is the most overpriced?
By our measure, La Mer The Night Recovery Concentrate ($670), Chanel Sublimage La Crème ($505) and La Prairie Skin Caviar Liquid Lift ($545) top the list: each costs 20+ times its category's median price and scores at or below median efficacy.
How often is the Index updated?
Every quarter, from a fresh snapshot of the database.
