A Beginner’s Guide to Serums

At Le Mieux, serums aren’t just part of our skincare lineup—they’re our specialty. As a professional skincare brand trusted by estheticians and dermatologists around the world, we’ve built our reputation on advanced, high-performance serums that deliver real results.

Whether you’re building your first routine or just trying to understand when and how to apply serums, this guide has you covered.

What Is a Serum, Anyway?
A serum is a lightweight, fast-absorbing skincare product that delivers a high concentration of active ingredients directly into the skin. Unlike moisturizers, which are designed to hydrate and seal in moisture, serums are focused on treating specific issues—think hydration, brightening, anti-aging, or calming inflammation.

WHEN TO USE A SERUM IN YOUR ROUTINE
Serums should be applied after cleansing and toning, but before moisturizing. Here's a simple order of operations to follow:

1. Cleanser – removes debris, oil, and makeup

2. Toner – balances your skin and preps it for treatment

3. Serum – delivers active ingredients deep into the skin

4. Moisturizer – locks in hydration and protects your skin barrier

5. SPF (AM only) – essential for protecting your skin from UV damage

HOW TO APPLY A SERUM (STEP-BY-STEP)

1. Cleanse and tone your skin
   Start with a clean canvas so your serum can penetrate effectively.
   
   
2. Use 1–2 pumps or drops
   Gently press or pat the serum into your face and neck—no need to rub aggressively.
   
   
3. Let it absorb
   Wait 30–60 seconds before moving to the next step. This helps prevent pilling and ensures the serum is fully absorbed.
   
   
4. Follow with moisturizer
   Moisturizer seals in your serum and adds an extra layer of hydration and protection.

Final Thoughts: Keep It Simple & Consistent
The key to getting results from your serum is consistency. Start with one serum that addresses your main concern, use it daily, and gradually build from there if needed.

Your skin will thank you.
