Every product gets two numbers. One measures the formula. The other measures whether it’s right for you. Here’s exactly how we arrive at both.
Most apps give you one number and call it a day. We think that’s incomplete. A product can be objectively safe and still wrong for your skin — or flagged by generic databases but perfectly fine for you.
An objective formula rating. It evaluates ingredient safety, formulation quality, and regulatory compliance. Same number for every user — it’s about the product, not the person.
A personalized compatibility rating. It cross-references the formula against your skin type, concerns, sensitivities, and conditions. Your score will differ from your friend’s.
Both scores land on the same 0–100 scale. Each range has a plain-English label so you don’t need to interpret the number yourself.
Your Skin Match Score isn’t one flat number. It’s a weighted average of up to ten goal-specific sub-scores, selected dynamically based on your profile.
How well the formulation fits oily, dry, combination, sensitive, or normal skin. Always evaluated.
Pore-clogging risk. Scored inversely using an evidence-based 0–5 comedogenic scale, weighted by INCI position.
Presence of proven actives like retinoids, niacinamide, vitamin C, AHAs, BHAs, peptides, ceramides, and hyaluronic acid.
Irritation potential. Cross-references fragrance, essential oils, harsh surfactants, and your specific sensitivities list.
From truly fragrance-free (100) to multiple synthetic compounds (0–10). “Parfum” is never treated as safe by default.
Flags retinoids, high-dose salicylic acid, hydroquinone, and other ingredients contraindicated during pregnancy.
Evaluates presence of retinoids, peptides, vitamin C, niacinamide, AHAs, CoQ10, resveratrol, and bakuchiol.
Multi-layer moisture support: humectants, emollients, and occlusives. Products that strip moisture score low.
Broad-spectrum SPF 30+ with photostable filters scores highest. Evaluated when your profile includes sun concerns.
Ceramides, cholesterol, fatty acids, centella, panthenol. Penalizes barrier-disrupting ingredients like harsh surfactants.
We don’t just score the product — we break down every ingredient in the INCI list and tell you exactly what it does, whether it’s a concern, and why.
Beneficial for skin. Proven actives, soothing agents, and well-tolerated base ingredients.
Neutral or standard cosmetic ingredients. Emulsifiers, thickeners, and preservatives within safe concentrations.
Potentially irritating or comedogenic for some skin types. Certain fragrances, essential oils, and moderate comedogens.
Known irritants, high-risk comedogens, or ingredients your profile specifically marks as unsafe. We explain exactly why.
We believe you should know how your scores are generated, and what our limits are. No black boxes.
Scores are generated by an AI system trained on cosmetic chemistry principles and regulatory data. Not a substitute for a dermatologist.
Barcode scans pull from Open Beauty Facts, a community-maintained database. We supplement with our own OCR when the label is available.
Your Skin Match Score gets more accurate as you scan more products and rate results. We infer your skin profile from patterns, not a quiz.
0% of our revenue comes from brands. No sponsored placements, no affiliate deals, no “preferred partner” arrangements. We score what we see.
