Précieux Anti-Age Serum
Précieux Anti-Age Serum shows little evidence it works as marketed — the actives don't reach effective levels.
Actives pyramid
What's actually in it, ranked by how well it's dosed.
What it does
Evidenced benefit intensity, derived from dosed actives.
The receipt
Every point of this grade, traced to the active, its dose, and the evidence.
Retinol at 0.01% — underdosed
Below the ~0.25% effective threshold, so the labeled benefit is unlikely.
Peptides present — concentration not disclosed
A recognized active, but without a labeled % we can't confirm it reaches the effective ~1% dose.
No product-specific evidence
Grade rests on ingredient dosing alone — no study on this exact formula.
Pros & cons

- Recognized formulation base
- Retinol appears underdosed (0.01%) — labeled benefit unlikely
- Peptides concentration not disclosed — can't confirm it's effective
- No product-specific study — grade rests on dosing alone
- Premium price for a sub-C efficacy grade
