Serum is an essential ally for your skin, thanks to its high concentration of active ingredients and its texture. Let's take an up close and personal look at this first basic step of any skincare ritual.

What exactly is a serum?

Serums are skincare products that are generally fluid in texture and whose purpose is to boost the effectiveness of skincare creams. If you already love the effect your anti-aging cream has on your skin, you’ll be amazed at how incredible the results can be when you start with a serum adapted to your needs.

How do serums work?

Thanks to their unique texture, serums have the ability to penetrate deep down into the skin. They also have a high concentration of active ingredients, which means they can provide spectacular results! Anti-aging serums, for example, truly go above and beyond, outperforming all other types of skincare products.

Do I really need to include a serum in my skincare routine?

To understand just how useful a serum can be, let’s have a little fun by comparing it to wearing underwear! Although you don’t have to wear it, once you’re used to it, it’s hard to go without! Not only is it more comfortable, it also has many other different functions.

And, to continue with our analogy, serum is always worn under your cream, the same way that underwear is worn under clothing. When combined, serums and creams provide you with the best possible result!

Serums and creams: what’s the difference?

There are actually two key differences between a serum and a cream:

• The concentration of active ingredients, which is significantly higher in serums.
• The texture, which is more fluid for serums and more dense for creams.

These two types of skincare complement each other perfectly, most notably because the lighter texture of the serum allows it to work deep down in the skin while the cream is essential for providing the protection and comfort your skin needs.

When should serums be used?

Ideally, you should use serums both in the morning and evening, all year long.
If you insist on applying it only once a day, evening is your best option.
In fact, nighttime is when your skin kicks into regeneration mode. That’s why anti-aging ingredients are always more effective if you let them do their work while you sleep!

Which serum should I choose?

With so many serums available, it can be rather daunting to choose the right one.

Let’s start by talking about serums with anti-aging virtues. You’ll want to choose one that has three essential active ingredients:

• - Hyaluronic acid, to keep your skin well hydrated—specifically because hydration is essential to ensuring the effectiveness of any anti-aging serum. As an added bonus, hyaluronic acid is a key contributor to visibly plumped skin.
• - A high-performance anti-aging peptide, to help care for the skin’s most important cells, thereby preserving skin’s youthful appearance.
• - An antioxidant, which can often be found in plants. In fact, nature has a simple rule when it comes to antioxidants: the more pigmented a plant is, the greater its antioxidant properties. Lierac Paris Laboratories’ serums, for example, contain antioxidants extracted from black or purple flowers.

Can I use a combination of several serums?

Absolutely! If you have different needs and are hesitating between two serums, you can definitely use them both! You can use the one that targets your biggest areas of concern at night and the other one during the day.

Which are the best among Lierac Paris Laboratories’ serums?

The HYDRAGENIST Serum is the ideal solution for helping the skin restore a perfect level of hydration. It promotes cell oxygenation thanks to biomimetic oxygen (and good oxygenation is the key to hydrated, radiant skin). HYDRAGENIST also contains hyaluronic acid.

For the best in anti-aging serums, there are two options available to you: Absolute Anti-Aging Booster Serum and PREMIUM the Cure.

The CURE, which is used the same way as a serum, is incredibly impressive and fulfills its promise in just 28 days. It reverses cell aging in no time, leaving skin looking youthful. This serum can be a great option when experiencing periods of intense physical or psychological stress, for example.

The PREMIUM Serum, for its part, is a complete skincare product that can be used year-round and both during the day and night. It has a great overall effect, and stands apart from the rest by promising to reduce the age of your skin’s dermis by 5 years*.

The secret behind the effectiveness of the two Premium serums is the best high-performance peptides, black flowers with the highest concentration of antioxidant properties and a hyaluronic acid concentrate exclusive to Lierac Paris Laboratories.

So, now that you know what makes serums so great, it’s time to test their effectiveness—and enjoy the results for yourself!
