Skincare Science FAQ

At OUMERE, skincare begins with biology—not marketing. These are the most common questions about skin health, anti-aging, and routines, answered in plain language and grounded in formulation work from our Palm Beach laboratory.

Q1: 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. A moisturizer traditionally sits on top to lock in hydration. OUMERE rethinks this split: serums like The Advancement and UV-R deliver actives with a light feel, while Serum Bioluminelle gives moisture without occlusive weight.

Q2: Do I need a separate eye cream or is an eye serum better?
Thick eye creams can feel heavy and perfumed. The Eye Serum is a lightweight, fragrance-free concentrate with soy–rice peptides, licorice, alpha-arbutin, suma, and bladderwrack. It’s designed to help the eye area look brighter, smoother, and refreshed—without heaviness.

Q3: What is the best skincare routine for sensitive skin?
Respect the barrier. Skip harsh scrubs, strong scents, and daily over-exfoliation. A simple OUMERE routine:
• Oil Dissolution Theory (gentle cleanse)
• No. 9 (use sparingly to refine texture)
• UV-R and The Advancement (antioxidant + peptide support)
• Serum Bioluminelle (hydration without congestion)

Q4: Why do some moisturizers cause breakouts?
Heavy occlusives can trap debris. Serum Bioluminelle uses a balanced lipid profile (e.g., watermelon, grapeseed) for moisture with a clean, non-comedogenic finish.

Q5: What are peptides and do they really work in skincare?
Peptides are short amino-acid chains used to signal the skin’s surface for a smoother, firmer look. OUMERE concentrates multiple peptide families in The Advancement and Advancement II to support visible texture, tone, and resilience.

Q6: How often should I exfoliate?
Aim for steady renewal, not strong peels. Start No. 9 three times weekly in the morning on dry skin; increase only if comfortable. Its calibrated AHA/PHA blend refines the look of skin while maintaining comfort.

Q7: What’s the difference between AHA, BHA, and PHA exfoliants?
• AHAs (lactic, mandelic): smooth texture/brightness.
• BHAs (salicylates): help with oil/debris.
• PHAs (lactobionic, gluconolactone): gentler exfoliation with a hydration feel.
No. 9 unites AHAs + PHAs for balanced, barrier-respecting renewal.

Q8: Is fragrance in skincare harmful?
Fragrance is a common source of cosmetic irritation. All OUMERE formulas are fragrance-free to prioritize comfort and performance.

Q9: What is “barrier health” and why does it matter?
Your barrier helps retain moisture and keep irritants out. When it’s disrupted, skin can look red, dry, or sensitive. OUMERE products—particularly Serum Bioluminelle and UV-R—are designed to support barrier comfort.

Q10: Do antioxidants in skincare actually work?
When stabilized and properly paired, antioxidants help address the visible effects of oxidative stress (dullness, uneven tone). UV-R and UV-R Concentrate use multi-extract complexes (green tea, ginseng, broccoli sprout, resveratrol) for a revitalized look.

Q11: How can I make my skincare routine more effective?
Consistency and compatibility matter most. Use formulas designed to layer cleanly, avoid irritants, and follow a predictable order so each step supports the next.

Q12: What’s the best serum to use after sun exposure?
Sunscreen is essential in the day. After daily exposure, antioxidant-rich serums help skin look balanced and refreshed. UV-R Concentrate is composed for PM; UV-R (AM) complements morning routines. Neither product is a sunscreen.

Q13: Are expensive skincare products worth it?
Price alone means nothing. OUMERE invests in rare actives, controlled composition, and limited cycles—performance over perfume or filler.

Q14: Why does OUMERE avoid acids in some products but use them in No. 9?
Strong daily acids can compromise comfort, so OUMERE excludes them from serums. No. 9 is the calibrated exception: AHAs + PHAs with botanicals for visible renewal while respecting the surface.

Q15: How do I layer serums correctly?
Apply from lightest to richest. Within OUMERE:

1. No. 9 (AM, as tolerated)

2. UV-R or The Eye Serum

3. The Advancement or Advancement II

4. Serum Bioluminelle (or Bioluminelle Concentrate at night)

At OUMERE, every formula belongs to a fragrance-free system grounded in biological research: disciplined renewal, barrier respect, and results that last.
