About SerumSavvy

SerumSavvy is an independent guide to skincare, haircare, beauty devices, and subscription boxes. Mireille Tan covered beauty supply chains and ingredient sourcing before reviewing products, and reads a label the way a formulator would — by active, concentration, and what a bottle actually costs to use.

Why cost-per-use beats the price tag

A pricey serum can be cheaper per day than a drugstore one you reach for twice as often. A subscription box can quietly outspend the products you'd have chosen yourself. We translate price into cost-per-use and flag what's worth pausing.

How we research

We start with full ingredient lists, published concentrations where available, brand disclosures, and current pricing. Reviews focus on the active that does the work, realistic results, irritation risk, and claims that aren't backed by anything on the label.

How comparisons are built

Individual product reviews come before ranked comparisons. Each comparison states its criteria and only includes options with enough current evidence to assess. A brand cannot pay for a better rating or position.

How this site makes money

Some links are affiliate links. If you buy or subscribe through one, we may earn a commission at no extra cost to you. Affiliate availability never decides whether a product is included, praised, or criticized.

Not medical advice

Skincare is individual. Patch-test new products, and for persistent or medical skin concerns see a dermatologist. Formulas and prices change — verify current details with the brand before buying.
