Organic face serums

What is a facial serum?

A facial serum is a skincare product highly concentrated in active ingredients. Thanks to its lightweight formula, a facial serum penetrates the skin quickly and deeply, making it highly effective for targeting specific skin concerns. For example, you can use a facial serum for dehydrated skin, an anti-wrinkle serum, an anti-redness serum, or a serum for acne-prone skin.
The formula of a Guérande Cosmetiques facial serum is made with ingredients sourced from the Guérande salt marshes: Mother Waters, green samphire, red samphire, macroalga Enteromorpha... When our laboratory develops a facial serum, it ensures its effectiveness on the skin through independently conducted tests, and also checks the formula to align with our commitment to offering certified organic cosmetics.

Why use a facial serum?

A facial serum is ideal for daily use or as a treatment over a few weeks, especially if you want to address a specific skin concern. Its high concentration of active ingredients makes it extremely effective, with visible results in a short time. It also allows you to personalize your skincare routine: you can easily add a serum to address a temporary skin issue without having to completely change the beauty ritual you already enjoy. Moreover, a serum can help improve the overall appearance of your skin. Regular use brings a higher dose of effective active ingredients to the skin whether it's for hydration, reducing wrinkles, or soothing redness.

How to apply an organic face serum?

An essential part of any daily beauty ritual, a facial serum should be applied after cleansing and before your moisturizer.
The application of a facial serum must follow a specific order in your skincare routine to maximize its benefits. Here are the ideal steps and timing:
1. Cleansing: Wash your face with a gentle cleanser suited to your skin type to remove impurities, excess sebum, and makeup.
2. Exfoliation (optional, once a week): If you exfoliate, do it after cleansing. This removes dead skin cells and prepares the skin for better absorption of products.
3. Toner: Use a toner to rebalance your skin’s pH and remove any cleanser residue. Toners also help prep the skin for better serum absorption.
4. Serum application: On clean, dry, and toned skin, apply your serum. Dispense a few drops onto your face and neck, then gently massage it in with your fingertips until fully absorbed. Use light pressure to help the product penetrate.
5. Moisturizer: After applying your serum, use a moisturizer to lock in the serum’s benefits and add extra hydration.

Most facial serums can be used morning and evening, but this depends on the formula and product instructions. Guérande Cosmetiques recommends following the directions on your specific product.

Why choose a natural face serum?

An organic face serum is formulated with ingredients of natural origin from organic farming, guaranteeing a composition free of parabens, sulfates, silicones, phthalates, artificial dyes and synthetic fragrances. Grown without pesticides or synthetic fertilizers, these active ingredients protect both the skin and the environment. Opting for a natural face serum also means favouring brands committed to sustainable practices and eco-responsible packaging, thus reducing their environmental footprint
An organic hydrating serum meets strict standards and is subject to rigorous controls. Certification labels ensure full transparency on the composition and origin of ingredients, giving consumers the opportunity to make informed choices. By integrating an organic face serum into your facial care routine, you support organic farming and adopt an approach that is respectful of your skin and your complexion.

The importance of a hydrating serum in a skincare routine

A hydrating serum is an essential ally to preserve skin health and radiance. More concentrated than a cream, it penetrates deeply and delivers essential hydrating active ingredients to help maintain the skin’s balance. Over time, external aggressors—pollution, cold weather, stress—naturally deplete the skin’s water content, leading to discomfort and signs of dehydration. Incorporating an organic face serum into your daily routine helps restore hydration and strengthen the skin barrier. Natural face serums act as hydration boosters, thanks to plant-based active ingredients rich in minerals and antioxidants. They also prepare the skin to better absorb subsequent treatments, maximizing their effectiveness. When applied morning and evening before a moisturizer, an organic face serum helps achieve softer, more radiant skin that’s protected from daily environmental stressors. Offer your skin a targeted, natural treatment to reveal its full glow.
