No. 9 Daily Liquid Exfoliant
The One Product That Changed It All
The foundation of visible renewal.
No. 9 represents a disciplined advance in skin-renewal science—designed to help skin look smoother, clearer, and more resilient. Developed over a decade in our private Palm Beach laboratory, No. 9 supports the skin’s normal renewal rhythms and primes it for the rest of the OUMERE regimen.
At the core of the range, No. 9 prepares skin for clean layering: refined texture, balanced tone, and a fresher-looking surface, without fragrance or heavy occlusives.
Formulated with lactic acid, mandelic acid, lactobionic acid, gluconolactone, and selected botanical extracts, No. 9 provides controlled surface exfoliation to reveal a smoother, more radiant look while respecting the barrier.

The Science Behind the Formula
No. 9 uses a calibrated mix of alpha hydroxy and polyhydroxy acids with botanical bioactives to encourage a visibly refreshed surface—aiming for steady progress over “quick fixes.” The goal isn’t the strongest burn; it’s reliable results that respect the skin’s barrier.
No. 9 Questions & Answers
Q: What makes No. 9 different from other exfoliants?
A: Most exfoliants are marketed on strength: the harsher the burn, the faster the glow. No. 9 was engineered over a decade to do the opposite: provide controlled, daily exfoliation that respects the barrier. Its calibrated mix of lactic, mandelic, lactobionic, and gluconolactone gently refines skin for a smoother, clearer look without over-stripping.
Q: Is No. 9 safe for sensitive skin?
A: Yes. No. 9 combines alpha hydroxy and polyhydroxy acids with rare plant extracts like mulberry, licorice, and grapeseed. This balance makes it suitable for a wide range of skin types—even those who usually avoid exfoliants.
Q: How does No. 9 fit into an anti-aging routine?
A: By removing surface buildup while maintaining the skin barrier, No. 9 primes the skin for serums like UV-R, The Advancement, and Serum Bioluminelle. The result is a routine that layers cleanly and works more effectively over time.
Q: How often should I use No. 9?
A: Start 3x weekly in the morning on dry skin, then build up to daily use if tolerated. Wait up to 30 minutes before layering serums for optimal performance.
Q: Why did OUMERE create No. 9?
A: It was the first OUMERE formula: born out of the need for an exfoliant that didn’t sacrifice barrier health for quick results. No. 9 remains the foundation of the system, offering disciplined, reliable renewal instead of short-term fixes.
No. 9 should only be used with OUMERE products to avoid irritation and to experience the most powerful and profound anti-aging results. Apply several drops onto a cotton pad. For those with sensitive skin or skin not used to chemical exfoliation, add equal parts water to cotton pad to dilute. Beginning at the forehead, pat cotton pad gently onto face, neck, and décolleté. Do not rub product into skin as this can cause irritation. There is no need to rinse product off, No. 9 will cease exfoliating after approximately 30 minutes when your skin naturally returns to its normal pH level. Wait at least one minute before applying additional products. The longer No. 9 stays on skin before applying next product, the more exfoliation your skin will experience.
