DAILY SERUM 405
The DAILY SERUM 405 is the new expert treatment developed by Dr. Patricia Delarive – an antioxidant shield serum designed to protect the skin from oxidative stress, prevent premature aging and correct uneven skin tone.
Formulated as a true daily repair and prevention treatment, it combines powerful, highly concentrated actives :
✔ Pure Vitamin C 5% : a powerful antioxidant that neutralizes free radicals, stimulates collagen synthesis and enhances radiance for firmer, more resilient skin.
✔ Stabilized Golden C 5% : an innovative, oxidation-resistant form of Vitamin C providing continuous protection and long-lasting glow without irritation.
✔ Niacinamide 5% : works synergistically with Vitamin C to reduce dark spots, inhibit melanin transfer and visibly even out the complexion.
✔ Exclusive Phyto-Hormonal Complex : derived from medicinal plants, it mimics the action of female hormones on fibroblasts to reactivate collagen and elastin production, restoring density, elasticity and firmness.
✔ Hyaluronic Acid : maintains optimal hydration, strengthens the skin barrier and ensures lasting comfort and suppleness.
Day after day, the skin is better protected, brighter and more even.
Suitable for all women from 20 years old and for all skin types, including sensitive.
Formulated without retinol.

Reactivation of the skin’s natural mechanisms, particularly collagen production, to restore density and elasticity. Driven by the exclusive phyto-hormonal complex, which stimulates fibroblasts, firms the skin and redefines facial contours.
Smoothing and regeneration without retinol. The formula focuses on biostimulation and rejuvenation to refine skin texture and reveal a more even, radiant complexion.
Protection and cellular correction ensured by Vitamin C and Niacinamide. They protect against oxidative stress, correct dark spots, strengthen the skin barrier and restore hydration for a radiant, resilient complexion..
Dr. DELARIVE RESPONDS
From the age of 30, cellular metabolism gradually slows down. The natural production of collagen, elastin, and hyaluronic acid decreases, which directly impacts the density and firmness of the skin. This phenomenon is accentuated in women by the decline in hormones, which strongly influences skin balance.
A targeted biostimulation approach can then make the difference: by reactivating fibroblasts, certain active ingredients such as peptides or phyto-hormones (particularly in women) can restart collagen production, improve skin elasticity and gradually redefine volumes.
Not necessarily. It all depends on the form. HPR (Hydroxypinacolone Retinoate), used in some new-generation formulas, is a retinoid that's particularly well-tolerated, even by sensitive skin. It provides all the recognized effects of retinol—cell renewal, wrinkle reduction, and improved skin texture—without the typical irritation associated with more aggressive retinoids.
Phytohormones are plant extracts capable of mimicking some of the effects of female hormones on the skin, particularly estrogen. They are of major interest in anti-aging cosmetics: they help boost collagen production, improve elasticity, and strengthen skin density, particularly in women over the age of 30, when hormone levels begin to decline.
Exfoliation works on the surface, often in a one-off manner. Resurfacing, on the other hand, goes further: it actively stimulates deep cell renewal. Thanks to active ingredients like HPR retinol, it not only smooths the skin, but also reduces wrinkles, evens out skin tone, and regenerates the skin as a whole.
Not at all. It's not the number of steps that matters, but the quality of the formulas and their synergy. A short, well-thought-out routine with all-in-one treatments concentrated in dermatological active ingredients can be more effective than a series of poorly adapted products. The key is to act on the key dimensions of skin aging: stimulation, regeneration, and protection.
There is no single miracle ingredient, but several families of complementary active ingredients.
Retinoids (such as HPR retinol) stimulate cell renewal and improve skin texture. Peptides work deep down to boost the synthesis of collagen and support fibers. Antioxidants, such as vitamin C, vitamin E, and shikonin, protect the skin from oxidative stress, which is responsible for premature aging.
Gentle exfoliants, such as glycolic acid or salicylic acid, help remove dead skin cells, smooth skin texture, and revive radiance. Finally, phytohormones help compensate for the decline in hormones in women over 30 by reactivating key skin functions.
