Lierac Glow Fresh Radiance Booster Serum 30 ml

Why choose this radiance-boosting serum for a dull, uneven complexion?

Lierac Glow Fresh Radiance Booster Serum is a serum with a fresh gel texture, suitable for all skin types. It combines three key ingredients highlighted by the brand: Lumiphenols®, derived from a climbing magnolia extract (Schisandra chinensis); a duo of high- and low-molecular-weight hyaluronic acids; and an antioxidant tulip flower extract, for which the laboratory has filed a patent. The formula contains 96% naturally derived ingredients.

A dull complexion, more noticeable dark spots, and skin that has lost its radiance: this serum addresses these concerns, just as our anti-dark spot serums do to even out the complexion. It brightens the skin and, day after day, evens out the complexion. In an evaluation conducted by the brand on 33 volunteers—using two applications per day and instrumental measurement—skin radiance was significantly improved in 87% of them after 28 days, and the visibility of dark spots was significantly reduced in 69%.

Its second benefit is hydration. The duo of hyaluronic acids maintains the skin’s moisture balance on the surface: the serum hydrates and plumps the epidermis. An instrumental measurement conducted by the brand on 10 volunteers showed that skin hydration lasted up to 72 hours after a single application. The gel texture melts into the skin without leaving a film, and its fragrance combines notes of bamboo water, bergamot, and luminous floral notes. In addition to these active ingredients, the formula includes common cosmetic moisturizing agents—such as glycerin, trehalose, and urea—present in small amounts.

This is a treatment meant for long-term use rather than a one-time application: the measured results were observed after four weeks of regular use. It’s naturally ideal for times when the complexion loses its radiance—at the end of winter, as summer winds down and the tan fades unevenly, or during busy weeks when the skin looks dull. Its lightweight texture layers effortlessly over your usual moisturizer—whether it’s a lightweight lotion or a richer cream—and doesn’t interfere with makeup.

A serum designed to address the appearance of dark spots loses some of its effectiveness if the skin remains exposed to UV rays without protection. We recommend pairing it in the morning with the État Pur Protect Visage SPF50+ mineral fluid: the serum enhances radiance and evens out the complexion, while the mineral filters in this very high-protection fluid limit the skin’s exposure to UV rays—one of the factors that exacerbate dark spots.

Our expert advice on the Glow Fresh Radiance Serum

Old and very pronounced dark spots—such as those caused by years of sun exposure or the patchy spots that appear during pregnancy—rarely respond to a single brightening treatment. This serum helps even out the appearance of the complexion; it does not replace medical advice when a dark spot is a cause for concern, and the warning about dark spots that change over time remains, by far, the most important. To assess the results, it’s best to compare two photos taken under the same lighting—one at the start and one after a month—rather than relying on what you see in the mirror every day.

A dull complexion can also result from the buildup of dead skin cells on the skin’s surface. For skin that can tolerate it, a gentle exfoliation once a week, in the evening, prepares the skin to absorb the serum. However, there’s no need to pile on “radiance-boosting” products in the same routine: beyond two or three treatments, the skin is primarily at increased risk of discomfort.

FAQ

Can I use Lierac Glow Fresh Radiance Booster Serum without applying cream on top?

A serum is a concentrated product with a fluid texture that doesn’t leave the comfortable film of an emulsion on the skin. For oily skin in the summer, it may sometimes be sufficient on its own in the morning; for normal to dry skin, a moisturizer is still necessary to prevent tightness.

Can I combine Lierac Glow Fresh Radiance Booster Serum with another serum?

Yes, provided you apply the products from the lightest to the thickest texture and allow each layer to absorb before applying the next. If you’re using a serum containing exfoliating acids or retinol, it’s best to alternate between morning and night to minimize the risk of irritation.

Can I use Lierac Glow Fresh Radiance Booster Serum on sensitive skin?

According to the brand, the serum has been dermatologically tested. For skin that reacts easily, testing it on a small area—such as under the jaw—for a few days will help you check for tolerance before applying it to your entire face.

Is Lierac Glow Fresh Radiance Booster Serum suitable for dehydrated skin?

Yes. Dehydration is a temporary lack of moisture that can also affect oily or combination skin: it manifests as tightness and fine lines that fade once the skin regains its moisture. The serum can be incorporated into these routines, provided you also pay attention to cleansing: very hot water or water with high mineral content often exacerbates the feeling of tight skin.
