What is the difference between a serum and a moisturizer?

A serum is a lightweight treatment that delivers concentrated actives to the skin’s surface, while a moisturizer traditionally sits on top to lock in hydration. OUMERE serums deliver actives with a light feel, and Serum Bioluminelle provides moisture without occlusive weight.

Do I need a separate eye cream or is an eye serum better?

Heavy eye creams can feel occlusive. A lightweight eye serum absorbs quickly and supports a smoother, brighter look. The Eye Serum uses peptides and plant extracts to improve the appearance of dark circles and fatigue without heaviness.

What is the best skincare routine for sensitive skin?

Prioritize barrier respect and avoid harsh acids, scrubs, and perfume. A simple routine: Oil Dissolution Theory for cleansing; No. 9 sparingly to refine texture; UV-R and The Advancement for antioxidant and peptide support; finish with Serum Bioluminelle for hydration without congestion.

Why do some moisturizers cause breakouts?

Heavy occlusives can trap oil and debris. Serum Bioluminelle uses a balanced lipid profile with non-comedogenic oils to provide moisture while maintaining a clean, lightweight finish.

What are peptides and do they really work in skincare?

Peptides are short chains of amino acids used to signal the skin’s surface for a smoother, firmer appearance. OUMERE concentrates multiple peptide families in The Advancement and Advancement II to support visible texture, tone, and resilience.

How often should I exfoliate?

Aim for steady renewal rather than strong peels. Start with No. 9 three times weekly in the morning on dry skin, then increase only if comfortable. Its calibrated AHA/PHA blend refines the look of skin while maintaining comfort.

What’s the difference between AHA, BHA, and PHA exfoliants?

AHAs like lactic and mandelic smooth texture and brighten; BHAs like salicylates help with oil and debris; PHAs like lactobionic acid and gluconolactone exfoliate more gently while drawing in hydration. No. 9 unites AHAs and PHAs for balanced, barrier-respecting renewal.

Is fragrance in skincare harmful?

Fragrance is a common source of cosmetic irritation. OUMERE formulas are fragrance-free to prioritize comfort and performance.

What is barrier health and why does it matter?

The skin barrier helps retain moisture and keep irritants out. When it’s disrupted, skin can look red, dry, or sensitive. OUMERE products are designed to support barrier comfort so hydration and actives perform predictably.

Do antioxidants in skincare actually work?

Stabilized antioxidants help address the visible effects of oxidative stress, which can make skin look dull or uneven. UV-R and UV-R Concentrate use multi-extract complexes—such as green tea, ginseng, and resveratrol—to support a revitalized appearance.

How can I make my skincare routine more effective?

Consistency and compatibility matter. Use formulas designed to layer cleanly, avoid irritants, and follow an order that supports absorption: cleanse, refine as tolerated, apply targeted serums, then finish with lightweight moisture.

What’s the best serum to use after sun exposure?

Sunscreen is essential during the day. After daily exposure, antioxidant-rich serums help the skin look balanced and refreshed. UV-R Concentrate is designed for PM use, while UV-R (AM) complements morning routines. Neither product is a sunscreen.

Are expensive skincare products worth it?

Price alone isn’t a guarantee. Focus on composition, stability, and how products layer. OUMERE invests in rare actives, controlled composition, and limited cycles to prioritize performance over perfume or filler.

Why does OUMERE avoid acids in some products but use them in No. 9?

Daily strong acids can compromise comfort, so OUMERE excludes them from serums. No. 9 is a calibrated exception: a gentle AHA/PHA blend with botanicals for visible renewal while respecting the skin’s surface.

How do I layer serums correctly?

Apply from lightest to richest. Within OUMERE: No. 9 in the AM as tolerated; then UV-R or The Eye Serum; next The Advancement or Advancement II; finish with Serum Bioluminelle (or Bioluminelle Concentrate at night) for a refined, luminous finish.

Autumn 2025 — Comfort, Clarity, Continuity

As air turns cooler and drier, I refine my routine for steady radiance and consistent anti-aging: calibrated exfoliation, peptide signaling, antioxidant conditioning, and a lipid finish that feels weightless—never waxy. This is my exact AM/PM protocol for autumn.

From the Lab: “Autumn is about continuity—keeping summer clarity while restoring water balance. I prioritize gentle morning renewal, signal peptides at night, and a biphase finish that seals comfort without occluding.” — Wendy Ouriel, M.S. Cellular Biology

Morning Protocol

Renew: No. 9 on dry skin, 3–7× weekly. Wait up to 30 minutes.
Condition: UV-R for lightweight antioxidant hydration.
Signal: The Advancement for peptide support.
Finish: Serum Bioluminelle as the final serum step. Follow with sunscreen.

Evening Protocol

Cleanse: Oil Dissolution Theory, massage 30–60s, emulsify, rinse.
Target: The Eye Serum to the orbital bone.
Peptide Renewal: The Advancement II. Let sit ~60s.
Antioxidant Density: UV-R Concentrate, thin layer.
Seal: Serum Bioluminelle Concentrate as the final step.

Why These Steps Work in Autumn

Humidity shifts can exaggerate TEWL and tightness. No. 9 sets a smooth baseline without over-stripping; UV-R restores a comfortable, bright look; peptide signaling in Advancement/Advancement II supports a refined, elastic appearance; Bioluminelle finishes with a breathable lipid profile that feels light but lasting.
