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.

OUMERE Laboratory

Research & Methods — The Biology Behind OUMERE

OUMERE is led by Wendy, M.S. in Cellular Biology, with additional study in physics and mathematics at Stanford University. Her academic work includes published research on ovarian development in the black widow spider, and side projects in wound healing and anti-aging biology. Today, that rigor powers a private Palm Beach laboratory focused on cosmetic science: disciplined formulation, microscopy, ingredient testing, and transparent methods.

Scientific Foundation

Graduate field: Cellular Biology (M.S.). Independent study in physics and mathematics at Stanford (distinct from biology work).

Primary research: Ovarian development in the black widow spider — characterizing pre-vitellogenic stages that precede egg formation.

Secondary focus: Biological basis of wound healing; exploratory work on natural ingredients and anti-aging biology as they relate to visible skin quality.

Publication: Journal of Invertebrate Biology.

Cellular signaling Tissue formation Barrier biology Oxidative balance

Laboratory Methods & Instrumentation

Microscopy & imaging: Electron microscopy, light microscopy.

Histology: Tissue preservation, embedding, staining (incl. Mallory trichrome).

Molecular techniques: Western blots, PCR.

Product testing: Ingredient screening, stability checks (light/heat), phase behavior, texture & layering trials, ex vivo observations on human skin samples.

Our Research Framework

Biology-first: Begin with cell signaling & tissue behavior; formulate to respect barrier and renewal rhythms.

Minimalist chemistry: Prioritize bioavailable plant extracts, stabilized peptides, and non-oxidizing lipids. Avoid unnecessary perfume and heavy occlusives.

Predictable layering: Every formula must play cleanly with the rest of the system, AM and PM.

Small-batch control: Composed in limited cycles for consistency over mass production.
