Goal-specific ranking

What deserves to come first for fine lines

Separate actives that can remodel over time from those that mainly create a temporary plumping effect.

Base priority and practical fit

What the priority tier means

Priority combines evidence, expected benefit, tolerability, practicality, time and cost. It is not an efficacy percentage. Evidence certainty is shown separately.

TretinoinThe strongest option here for photoaging, but access, irritation, and clinical oversight make it less practical.

How to read the tiers

The tier shows priority for this goal; evidence certainty appears in a separate column. A lower tier does not mean harmful.

Frequently asked questions

How long should I try an active?

It depends on the active. The ledger shows a reasonable evaluation window; changing too early makes it impossible to know what works.

Do I need the number-one ingredient?

No. The base ranking is a starting point. Tolerance, pregnancy context, access, and routine can make another option more suitable.

Why did my personalized order change?

Personalization adjusts practical suitability. Evidence certainty and the base priority tier remain visible.

Commission never changes a ranking.
