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.

About OUMERE

OUMERE

Scientific skincare, formulated by a cellular biologist, made in small editions in Palm Beach, Florida.

Who we are

OUMERE is a research-driven skincare company founded by Wendy Ouriel, M.S., a cellular biologist. We formulate and bottle in our private lab in Palm Beach, Florida, and release products in limited monthly editions to preserve freshness, control quality, and maintain scarcity.

Founded: 2017
Discipline: Cellular biology-led formulation
Manufacturing: In-house, small-batch, lot-tracked
Location: Palm Beach, Florida, USA

Why OUMERE exists

Until the age of 25, Wendy never experienced acne, redness, or sensitivity. After a month of conventional luxury anti-aging products, she observed new breakouts, barrier stress, and irritation. Her academic work in extracellular matrix biology and the mechanisms of skin aging clarified a pattern: many products—across luxury, dermatologist, and “natural” categories—include potential irritants such as fragrance, essential oils, drying alcohols, and reactive fillers that can overwhelm the skin’s barrier.

OUMERE was created as a research-first alternative: formulations designed to work with biology rather than against it, produced in small volumes to keep variables tight (freshness, lot control) and to maintain precision.

Research & method

Every OUMERE formula begins at the bench: ingredient review, compatibility mapping, and stability testing, followed by small-scale iteration and controlled scale-up. We document results in the OUMERE Research Library and translate findings into practical steps in our Guides and Research & Methods.

Literature & mechanism first: pathway-level rationale before any ingredient is weighed.
Barrier-aware design: prioritize epidermal comfort and low reactivity.
Edition control: limit batch size; lot test, then release.
Field feedback loop: anonymized observations inform subsequent editions.

What we make

Our range is intentionally concise. Each formula has a defined role so routines remain simple, tolerable, and effective.

Bioluminelle — signature oil-serum emulsion for daily barrier support.
Cleansers & tonics — gentle cleansing and pH stewardship without harsh surfactants.
Serums — targeted actives placed where the literature supports them and the skin tolerates them.
Moisture & finish — weight-calibrated finishers for day and night.

Editor’s Lab Note

Biological principle: Skincare outcomes are most stable when formulations respect barrier integrity and minimize irritation load. OUMERE’s edition model keeps variables tight (freshness, lot control), allowing the biology to do the work with fewer confounders. See the Research Library for primary sources and the Guides for application.
