What it does
- Gives you a clear alternating system: Collagen for plump lift, PDRN for recovery glow.
- Keeps finish language consistent so products do not fight under makeup or SPF.
- Simplifies gifting and routine teaching — one ritual, two outcomes.
- Ideal catalog SKU for duo / kit PDP patterns in crawl demos.
How it works
- Bottle A (Collagen): CO₂ foam + hydrolyzed collagen / HA / peptides for hydration and lifted look.
- Bottle B (PDRN): CO₂ foam + Sodium DNA / 5% niacinamide for revitalized glow.
- Use on different nights (or AM/PM split) so each formula can be evaluated clearly.
- Neither bottle should be shaken; both are leave-on after bubbles collapse.

How to use
- Routine step
- Essence / serum system (alternating)
- Amount
- 1–2 pumps per bottle, per use
- Frequency
- Alternate nights or AM/PM split
- When
- Alternate nights or AM/PM
- 1Night A — Collagen: cleanse → 1–2 pumps → press until foam collapses → moisturize if needed.
- 2Night B — PDRN: same ritual with the PDRN bottle.
- 3Optional split: Collagen in the morning under SPF; PDRN at night.
- 4Do not shake either bottle. Do not layer both foams in one step unless your skin is very resilient.
- 5SPF every morning regardless of which bottle you used the night before.
Usage notes
- Each bottle: 1–2 pumps per use (see individual PDPs).
- If reactive, use each bottle 3× weekly rather than nightly.
- Collagen has trace fragrance; PDRN is fragrance-free — patch-test Collagen if fragrance-avoidant.
- Label bottles Night A / Night B if sharing a bathroom shelf.
Patch test
- 1Patch-test each formula separately on the forearm (24 hours).
- 2Introduce one bottle for 3 nights before adding the second to your rotation.
