Retinol Correxion Deep Wrinkle Serum

What a month of use costs vs. the category
- About $7 per month to use
- $22 for 30 ml, used about once a day (about 0.3 ml each time), so a bottle lasts about 3.3 months
- Frequency is set by Retinol, which is used no more than 7x a week, so a bottle stretches further
- Band: $6/month or less earns full marks, $60/month or more hits the floor.

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Retinol | n/a | Studied |
A patented stabilised retinol with a mineral complex (magnesium, zinc, copper) and a little ascorbic acid and vitamin E, in an opaque, potency-preserving pump built to limit air and light. The percentage is undisclosed and the marketing runs hot, but RoC has formulated retinol for decades and the packaging is right for it.
How it’s delivered
Air- and light-sensitive actives (vitamin C, copper peptides) lose potency fast in the wrong packaging, so delivery and the bottle are scored, not just what’s on the label.
