Why apply a serum?

Pourquoi appliquer un sérum ?

In an effective facial skincare routine, a serum plays a key role. More concentrated in active ingredients than a cream, it acts in a targeted manner to meet the specific needs of the skin.

Radiance Serum: the facial treatment that illuminates, smoothes, and reactivates the skin

The Radiance Serum is part of this complementary approach: it smoothes the skin texture, brightens the complexion, and supports the skin's natural biological mechanisms, while strengthening the effectiveness of the moisturizing cream applied afterward.

Formulated with natural active ingredients and biotechnologies inspired by nature, the Radiance Serum is designed for those looking for a facial serum that is effective and respectful of skin physiology.

Why include a radiance serum in your facial skincare routine?

The skin functions according to precise biological cycles. To preserve its radiance and quality, it needs care that can act deeply without disturbing its balance.

Incorporating a radiance serum into your routine allows you to provide the skin with a high concentration of targeted active ingredients capable of stimulating cell renewal, improving skin texture, and reviving complexion luminosity. Used before moisturizing cream, the serum preps the skin and optimizes the penetration of the active ingredients applied afterward.

A facial serum to smooth skin texture and illuminate the complexion

The Radiance Serum acts directly on the skin's surface to improve its overall quality. Its formula relies on a dual action: exfoliating and smoothing.

The gentle exfoliating action of fruit-derived AHAs

The fruit acids (AHAs) present in the Radiance Serum promote gentle, gradual exfoliation. By helping the skin shed dead cells accumulated on the surface, they contribute to refining skin texture, evening out the complexion, and revealing the face’s natural radiance.

This respectful exfoliation also supports cell renewal, an essential process for maintaining luminous and homogeneous skin.

Natural myorelaxing active ingredients for visibly smoother skin

In addition to AHAs, the Radiance Serum incorporates natural myorelaxing active ingredients, such as Acmella oleracea and baobab extract. These ingredients, often described as botox-like, act on the skin's micro-tensions responsible for expression lines.

The result: features are visibly smoothed, the skin looks more relaxed, and the face regains a rested appearance.

Radiance serum: a solution suited for blemish-prone and mature skin

Thanks to its balanced formulation, the Radiance Serum meets the needs of different skin types without compromise.

A facial serum for blemish-prone skin

Blemish-prone skin fully benefits from the smoothing action of AHAs, which help limit the thickening of the stratum corneum and improve skin texture.
The presence of comfrey, a medicinal plant used since antiquity, supports the skin's natural repair mechanisms and aids the healing process.

The skin is clearer, more homogeneous, and visibly soothed.

A natural anti-aging serum for mature skin

Mature skin finds a targeted ally in the Radiance Serum. Baobab extract and Acmella oleracea help firm the skin and smooth expression lines, all while respecting the natural mobility of the face.

This natural anti-aging serum acts without freezing features, by supporting the skin in its biological mechanisms.

A facial serum that plumps the skin and preserves its elasticity

The Radiance Serum also contains persimmon extract, known for its antioxidant properties. This active ingredient plays a key role in preserving skin elasticity and protecting the skin against premature aging.

By supporting the suppleness and density of the skin, the serum contributes to a visible plumping effect. The skin appears more bouncy, comfortable, and better armed against external aggressors.

Maximizing the effectiveness of your moisturizing cream with radiance serum

Used before the moisturizing cream, the Radiance Serum acts as a true skincare booster. It provides the skin with complementary active ingredients derived from biotechnology that reinforce the action of moisturizing creams.

COMPLEX G5©: a biotechnology inspired by nature

At the heart of the formula is our patented COMPLEX G5©, derived from sprouted seeds. This complex combines buckwheat and amaranth, which complement the wheat and oat found in the moisturizing cream.

Inspired by the natural germination process, COMPLEX G5© releases essential micronutrients and helps reactivate the skin's cellular cycles, a mechanism demonstrated by genomic study.
Buckwheat is distinguished by its strong antioxidant power, its ability to support microcirculation, and its muscle-relaxing effect.

Radiance serum and mature skin: a targeted action against signs of aging

For mature and dry skin, the Radiance Serum ideally complements the Anti-Aging Moisturizing Cream. It provides specific active ingredients that stimulate cell renewal, smooth fine lines, and revive complexion radiance.

With continued use, the skin gradually regains its vitality and balance. Signs of skin aging diminish, without ever seeking to mask or deny the passage of time.

How to apply a radiance serum for optimal results?

The Radiance Serum is applied to clean, dry skin, before the moisturizing cream.
One to two pumps are enough for the entire face and neck.

It can be used in the morning and/or evening, depending on the skin's needs and the season. Applied regularly, it helps to durably improve the skin's quality, radiance, and texture.

For mature and dry skin, the Radiance serum complements the Anti-Aging Moisturizing Cream by providing complementary active ingredients to stimulate cell renewal and smooth fine lines. Gradually, the complexion regains its radiance and signs of skin aging diminish. Discover the mature skin ritual
