Our methodology

The 4 rating criteria

Each review breaks down the experience on 4 axes (plus an overall rating) — not a single Amazon-style star. These criteria feed the product score via our weighted engine (see below).

Efficacy

Does the product do its job? Felt hydration, soothing, barrier repair… depending on category.

Texture

Application comfort: greasy, sticky, matte or glowy finish, ease to spread and layer.

Hydration

Does skin feel tight during the day? Lasting comfort, not just at application.

Tolerance

Redness, stinging, reactions — central for sensitive and reactive skin.

How the product score is calculated

The displayed score (rating + recommendation %) is not a simple average. Each review is weighted then aggregated:

• Recency — newer reviews count more (decay over ~12 months).
• Reviewer trust — complete profile, tenure, helpful votes received.
• Credibility — anti-spam filter (short text, abnormal velocity).
• Bayesian average — prevents 5★ displays from just 2 reviews.
• Weighted recommendation % — not a simple yes/no percentage.
• Personalized score — same engine, matched to your beauty profile.

« What people like / What disappoints »

Since June 2026, you can add pro/con tags when writing a review (texture, scent, efficacy…). They are aggregated as percentages on the product page. Reviews published before this feature have no tags: the block then shows a summary based on the 4 criteria and the recommendation rate.

Where data comes from

• Reviews — published by registered members, one review per person and product. Skin type and usage duration required.
• INCI — entered by members in reviews and contributions, completed over time.
• Photos — Leclerc parapharmacy; manual moderation of questionable images.

Independence

Skinvisor is not affiliated with cited labs (Avène, La Roche-Posay, Bioderma…). No purchase affiliate links — rankings are driven only by community reviews.

Brands cannot pay to improve their ranking. The site is still young on review volume — scores refine with real contributions.
