A true powerhouse of efficiency, serums can address lots of different skin concerns: dehydration, imperfections, dull complexion, dark spots, and more. But what is a serum, and how should you use it? What’s the best way to integrate one into your skincare routine for maximum effectiveness? As usual, we’re here to explain everything.
Summary
What is a serum and what is it for?
A facial serum is an ultra-concentrated blend of active ingredients. Its water-based formula is often light and fluid. Its texture is much lighter than a cream, which allows the ingredients to be absorbed deeply into the skin. A serum often has a low molecular weight: this means its molecules are very small. This helps the ingredients to reach the dermis, which is the densest and richest layer of the skin (containing collagen and elastin, among others). It effectively prepares the skin for the absorption of subsequent treatments, boosting their effectiveness.
A serum is a deep and targeted treatment. It’s designed to address specific skin needs. It can focus on a flagship active ingredient (such as hyaluronic acid and Bio-Retinol, for example), or combine different active ingredients with different properties. You can easily find one that’s adapted to your needs: redness, dehydration, lack of radiance, dark spots, dry skin, blemishes, blackheads...
How is it different from a cream?
While cream and serum are both facial treatments, these products serve different functions. Each has its own purpose and they complement each other perfectly.
Creams have a thicker formula than serums. Creams are not designed to penetrate the epidermis (the skin’s top layer), but to reinforce or create a protective barrier on it (the hydrolipidic film). This is the opposite principle of the serum, which penetrates deep into the skin.
Cream is composed of several ingredients in small quantities. It’s a treatment that nourishes the outer layer of the skin and protects it from external irritants. Serums, with their more targeted action, help to enhance the effectiveness of moisturizing creams. Both products work together to enable the optimal hydration of your skin.
How do I use it?
After cleansing your skin, apply your serum. Place a few drops into the palm of your hand, and then massage these on to your face. Then continue your routine with your moisturizer, to seal the serum's actives into your skin. Simple.
How do I choose a serum adapted to my needs?
Choosing a facial serum is primarily about what your skin wants and needs, and helping you to handle specific skin concerns. The ideal serum depends on the issues you may encounter with your skin; it will respond to a specific and targeted action.
Do you have dehydrated skin that feels tight? Opt for our Hyaluronic Acid + Panthenol Serum.
Wrinkles, fine lines or dark spots? Choose our Bio-Retinol + Argireline® Peptide Serum.
Do you have oily skin and enlarged pores? Go for our Salicylic Acid + Niacinamide Serum.
Do you have a dull complexion and want to give your skin a boost? Choose our Vitamin C + Glycolic Acid Serum.
For a complete skincare routine, the serum is a perfect complement to other treatments. For more intense hydration or to correct various imperfections, these ultra-concentrated formulas are the allies of clear and radiant skin.
