The disciplined start of the OUMERE system. No. 9 is a calibrated blend of alpha- and poly-hydroxy acids formulated to exfoliate dead corneocytes without disrupting the lipid barrier or the skin’s acid mantle. It prevents the appearance of inflammation-aging while priming the complexion for UV-R, The Advancement, and Serum Bioluminelle.

Composition
Lactic + mandelic + lactobionic + gluconolactone in a base matched to the skin’s acid mantle. Includes mulberry, licorice, and goldenseal to support a calm-looking barrier during the exfoliation window.
Ritual
Apply on clean, dry skin; wait; then layer UV-R → The Advancement → Serum Bioluminelle. Steady, predictable progress.
Biological Mechanism of Action
Lactic Acid
Exfoliates surface corneocytes while supporting ceramide-associated comfort and Natural Moisturizing Factors (NMF).
Gluconolactone (PHA)
A high-molecular-weight acid that renews the surface slowly to help minimize neurogenic stinging and support antioxidant defense.
Mandelic Acid
Lipophilic properties support the appearance of clearer pores and smoother texture without dehydrating the aqueous layer.
Soothing Botanicals
Goldenseal and licorice support a calm-looking complexion during chemical exfoliation.
“Not the strongest burn—the smartest polish. We avoid the inflammatory burn to preserve long-term cellular health.”
What it does (cosmetic)
- Refines the look of surface texture by loosening desmosome bonds.
- Supports a clearer-looking complexion by helping prevent the appearance of pore blockage.
- Supports the look of a balanced acid mantle.
Signature pairings
- UV-R — antioxidant conditioning
- The Advancement — peptide refinement (Step 2)
- Serum Bioluminelle — barrier fortification (Step 3)
Sensory profile
Water-light; sets cleanly. Fragrance-free. Designed for a polished, non-tight finish.
How to use
Morning, 3–7× weekly
On dry skin, sweep No. 9 over face and neck. Wait 5–30 minutes before layering UV-R, The Advancement, then Serum Bioluminelle.
Sensitive introduction
Start 2–3× weekly; optionally dilute with distilled water. Extend wait time gradually as comfort allows.
Do
- Use regularly for steady, elegant results.
- Give layers time—~60s between serums improves finish.
- Right-size frequency by season and sensitivity.
Don’t
- Chase “burn” (neurogenic inflammation signals damage).
- Stack competing strong actives (e.g. Retinol/Vit C).
- Skip patch testing when introducing any formula.

Scientific Note: OUMERE formulations are developed for cosmetic use, focusing on the visible health and aesthetic quality of the skin. They are not pharmaceuticals and are not intended to diagnose, treat, or cure any medical condition.
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.
